How to protect Home Security Cameras from pollutants

Indoor Housings
Indoor housings must protect the Home Security Cameras and lens from pollutants such as dust and other particulate matter, a corrosive atmosphere, and tampering or vandalism. Indoor housings are constructed of painted or anodized aluminum, painted steel, stainless steel, and several types of plastic. The material for plastic housings must be flameproof or flame-retardant, as designated by local codes and UL recommendations. The housings must have sufficient strength to protect the lens and camera, and be sturdily mounted onto a fixed wall or ceiling mount, or recessed in a wall or ceiling. The lens should view through a clear window made of safety glass or plastic. Recommended plastic window material is either high impact acrylic or polycarbonate with a mar-resistant finish. The electrical input/output access locations should be designed and positioned for easy maintenance. For easy access and servicing of internal parts, the top half of the housing should be hinged or be able to slide open, or be removable. In some designs, the entire camera/lens assembly is removable for servicing.
The common rectangular housing is available in many sizes and is the least expensive. For vandalism protection, many housings are available with key locks or tamperproof hardware that allows the cover to be removed only with a special tool. In very high risk areas, welded stainlesssteel housings with thick polycarbonate windows (3/8 or 1/2 inch) and high-security locks are used. Some housings are designed to provide concealment and improved aesthetics by recessing them into the wall or ceiling. The five housing types that account for most security installations are:
(1) rectangular
(2) dome
(3) wedge
(4) triangular
(5) wall- and ceiling-recessed and surface-mounted.

Indoor Types

1. Rectangular
The most popular type of housing is the standard rectangular design since it can be fabricated at low cost, is sturdy, and is available from many manufacturers in many sizes and attractive styles. Under normal circumstances, indoor housings do not require any special corrosion-resistant finishes. The housings are made from painted or anodized aluminum, painted steel, or high-impact plastic, such as polyvinyl chloride (PVC), acritile buterated styrene (ABS), or polycarbonate (General Electric Lexan, etc.). In high crime areas and jails, stainless steel housings are used. Accessibility to the camera/lens assembly for installation and servicing is important. Video surveillance cameras are always mounted near or at ceiling height, on a pedestal, or at some elevated location requiring service personnel to be on ladders or power lifts. The housing design must permit easy access and serviceability under these conditions. Manufacturers provide one of several means to gain access to the housing:
(1) removable top cover
(2) hinged top cover
(3) top cover or camera/lens on slide
(4) removable front and/or rear cover
(5) hinged bottom cover (dome)
(6) top cover on slide.

2. Dome

A second category of indoor housing is of a round or hemispherical, clear or tinted dome in which a camera, lens, and an optional pan/tilt mechanism are housed. Chapter 14 described dome cameras in detail. The ceilingmounted hemispherical dome and the below-the-ceiling and wall-mounted domes on brackets look totally different from the rectangular housing, and often blend in better with architectural decor. Since they look like a lighting fixture, they are less obtrusive than rectangular housings. Since the hemispherical dome is circularly symmetrical, it can be in a fixed position and the Home Security Camera pointed in any direction to view the scene. A pan/tilt unit used in a dome can rotate and tilt the camera and lens while still remaining inside the confines of the dome. This is in contrast to cameras inside rectangular and other housings: if the camera moves, the entire housing assembly has to move as a unit. If the dome is tinted so that the person down at floor level viewing the dome cannot see the camera and lens, it is possible to point the camera in any direction without the observer seeing it move. This capability can act as an additional security deterrent because the observer does not know when he or she is under surveillance.
There are three different types of plastic dome materials through which the lens views the scene:
(1) clear
(2) semitransparent aluminum- or chrome-coated
(3) tinted or smoked plastic.
When the dome housing is used for protection only and its pointing direction need not be concealed, the clear plastic dome is the best choice, since it produces only a small 10 or 15% light loss. If the camera’s pointing direction is to be concealed for additional security a coated or tinted dome is required. The aluminized dome is the earliest version of the coated dome and attenuates the light passing through it by approximately two f-stops (equivalent to approximately a 75% light reduction or loss). While this type of dome is still in use, the preferred dome material is a smoked plastic or tinted plastic that attenuates the light approximately one f-stop, or 50%. In contrast to rectangular housings using flat plastic or glass windows with excellent optical quality and transmission, some dome systems add slight optical distortion to the video picture. In high-quality domes the image distortion is almost negligible, but in some systems the distortion or loss in resolution is noticeable.
Under this condition, there is at least symmetry of distortion, that is, the primary effect is that of a weak lens producing a small change in the focal length of the total lensing system and is usually not noticeable. If the camera/lens pointing axis is not perpendicular to the dome surface and looks at an oblique angle through the dome housing material, noticeable distortion will occur; for example, images may appear elongated vertically or horizontally. If the dome and camera are in a fixed position with respect to one another, the distortion is generally less noticeable than if the lens is scanning or tilting while the dome remains still.

3. Wedge Housing

One version of the wedge housing is designed to replace an existing standard 2 feet × 2 feet drop ceiling tile and another version is designed for surface mounting.There are no additional accessories required. The design allows for manual pan adjustments of 360 and minor tilt adjustments. After final pointing the center camera/lens section is restricted from rotating by tightening thumbscrews. The camera’s wedge shape aims the camera about 15 down from the horizontal. The front of  the protrusion has a viewing window of clear acrylic with no distortion and virtually no light transmission loss. Another version is a small surface-mounted wedgeshaped housing that can be attached to any ceiling. These are available in either a surface- or recessed-mounting configuration.

4. Corner Mount
For example a high-security housing of welded stainless steel with a polycarbonate window. The tamperproof corner mount camera housing has a camera bracket assembly permitting the Wireless IP Camera to be tilted vertically ±10 for minor adjustments of the vertical pointing angle. The lens viewing window permits viewing a 95 horizontal FOV and 75 vertical FOV. The optimum pointing direction for the lens and camera is 45 with respect to both adjacent walls and 45 down from the ceiling horizontal plane. For an elevator cab application this housing with a wide-angle, 95 horizontal FOV can view entire elevator cab with no hidden areas and provide 100% video coverage of the cab area. The high-security housing has a hinged, lockable cover for easy, controlled access to all internal parts, and a tough mar-resistant polycarbonate (Lexan) window. All mounting, video, and electrical power access holes are located on the rear and top surfaces and inaccessible to the public. The installation meets codes that require unbroken firewalls. Three different housing sizes of this design accommodate most CCD solid-state cameras and wide-angle manual- or automaticiris lenses or variable focus (vari-focal) lenses. Since the housing is exposed to the public, it is securely locked and manufactured using tamperproof materials, such as steel or stainless steel, and a polycarbonate (Lexan) window.
The plastic housing has a lockable front cover and all mounting and electrical access holes are out of sight, and not accessible to the public. The housing has an adjustable bracket for tilting the camera vertically. There are many manufacturers supplying these types of corner mount housings in materials ranging from stainless steel, steel, and plastic. Finishes include brushed stainless steel and painted aluminum, steel, and plastic.
5. Ceiling- or Wall-Recessed or Surface Mount
Recessed or partially concealed housings are often mounted in ceilings and walls. The round, semicircular, and tapered housings shown offer design flexibility since the camera and lens can be pointed in any horizontal direction while the square or rectangular ceiling tile remains in place. These housings are used where a low-profile (but not covert) type of surveillance camera is required.  These cameras are well suited for looking down hallways, at cash registers, etc. In ceiling installations, most of the housing, camera, and lens are mounted above the ceiling level. The only portion below ceiling level is a small part of the housing and the window through which the camera lens views. The cameras and lenses are accessible from below ceiling level by unlocking a cover that swings down, or by gaining access from the rear of the housing above the ceiling from an adjacent ceiling tile. It is important that all ceiling tile mount housings be securely attached to a structural member of the building above the ceiling with a chain or cable so that if the hanging ceiling support fails, the housing and contents do not fall to the floor or possibly injure personnel below.
With the increased use of video surveillance in public locations, be they government, industrial, or private, more attention is being given to the decorative and aesthetic features of the housing. These housings often have finishes of brass, gold, or chrome, with satin or polished finishes. They are also available with custom paint colors and textures, and custom-colored plastics. Several manufacturers offer special shapes and custom configurations for matching specific architectural designs.

Personal GPS Tracker is allowing elderly people to live independently longer

Personal GPS Tracker is allowing elderly people and those with limited functionality to live independently longer, with caretakers doing their work remotely. General Electric, for example, has a product in which ubiquitous sensors can accurately and unobtrusively determine an independent elderly person’s activity. Currently, simple tracking systems are more common, such as a GPS-programmed “geofence” that sends an alert to a caretaker if the person has left a predefined area. The device is targeted to people who suffer from Alzheimer’s disease, although it can be used with children and teenagers as well. Lawmakers should be more aware of the possibility of caretakers abusing devices such as the i-TAG and the more sophisticated sensor systems. If an abused person leaves his or her home to escape, the caretaker would be notified instantly. And if gadgets or software monitor call logs as well, an abused person might have even more limited recourse.
The abusive caretaker situation resembles, in some ways, the much more common occurrence of domestic violence and even electronic stalking by a stranger. It’s a relatively straightforward task to install a tracking device on a person’s car without her knowledge. And in at least one case, a victim of domestic abuse has sued the gadgetmaker, Foxtrax Vehicle Tracking, for aiding and abetting her abuser in an attack. The police are also using personal GPS tracking on the other side of the domestic violence battle: more states are using GPS to keep track of people with restraining orders against them,24 a tactic that law enforcement has previously used to keep track of people convicted of sexually abusing children.
Although it’s clear that applications that use a person’s data can help him live a more productive life, exercise more, or kick a smoking habit and in themselves can be useful and exciting, they can’t exist without the accompanying questions of privacy. Researchers try to envision a world in which these applications have existed for decades, and so they often put out the call for a more in-depth “conversation” about the questions that need to be asked and the implications that inevitably arise with such technologies. However, it’s still often the case that the privacy concerns regarding or vulnerabilities within a new technology, be it a GPS-based phone application or RFID-based toll tag, emerge only after the technology has been adopted and started to cause problems.
One of the most popular ways of addressing concerns is by allowing people to opt in or opt out of programs or technologies. However, in some cases it’s not feasible to opt out entirely. Therefore, there need to be various approaches to data collection and analysis that offer a range of privacy options. Included with each privacy setting should be clear, concise explanations of the ramifications of that setting. For instance, many people allow mobile phone applications to use their location if the application asks, but few people are fully aware of how those data are used and shared.

Here is the Best GPS Tracker that we currently have in stock:

Indoor and outdoor Wireless Camera pan/tilt platform and controllers

The joystick is moved forward or backward, left or right corresponding to the vertical (tilt) and horizontal (pan) movements of the camera/lens unit. Likewise, the thumb trackball is moved using the thumb to initiate pan and tilt. For the disk, touch-pad, and four-button design, left and right initiate panning, and top and bottom initiate tilt. The security officer watches the video monitor and can point the Wireless Camera to view any area within the pan/tilt rotation range. The platform and camera move in accordance with the control signal sent by the control unit. Pan/tilt platforms are available in a wide range of sizes from lightweight, pan-only units (scanners) for indoor applications to heavy-duty, environmentally protected pan/tilts for outdoor applications. Rugged outdoor units are environmentally enclosed and intended to withstand severe conditions of temperature, precipitation, dust, humidity, and high winds.
In the late 1990s the requirement for faster, more compact, and discreet PTZ surveillance cameras surfaced from casino, retail store, warehouse, and other applications. This resulted in the development of the high-speed video-dome camera system. The technology that made this innovation possible was the availability of small, high resolution, high sensitivity CCD camera sensors and associated DSP electronics. This, in turn, permitted the use of smaller zoom lenses. The Sony and Hitachi companies then developed the core component of the highspeed dome camera: a unitized digital pan/tilt drive package surrounding the miniature camera/lens assembly.
There are three primary applications for pan/tilt units:
(1) monitoring a fixed or point site, (2) monitoring an area site, and (3) monitoring a volume site.

A point site might correspond to a bank teller, where the area of interest is the teller and customer, and the business transaction. An area site might be a building lobby where the activity in the lobby is of interest. A volume site might be a warehouse where many vertical bays (levels) must be under surveillance at different times. For the fixed or point site, a single fixed camera and lens are suitable to view the entire area. In the area and volume cases, a single fixed camera cannot see the entire area of interest, so a panning and tilting camera and a zoom lens are required.

Applications that use pan/tilt mechanisms can be roughly classified into indoor and outdoor types, mounted in either an overt configuration—without a concealing dome or housing—or a covert application, where the pan/tilt mechanism and lens/camera unit are hidden in a dome, hidden behind some visually opaque window, or camouflaged by some other means. A common type used in indoor applications consists of a panning platform that rotates the camera via direct operator control or automatically pans from side to side to cover the specific area. A second type is the pan/tilt unit in which panning and tilting are done manually (under operator control) or automatically. Both types can be augmented with a remotely controlled zoom lens to change the FOV and therefore the instantaneous camera coverage within the full range of the scanner or pan/tilt unit. In outdoor applications, the pan/tilt mechanism and the housing containing the camera/lens must be designed to withstand wind loading, precipitation, dust, dirt, and all types of vandalism.

In an outdoor application there are two options:

(1) the lens and camera can be enclosed in an environmentally shielded housing and mounted on an environmental outdoor pan/tilt mechanism or

(2) the lens, camera, and indoor pan/tilt mechanism can be installed in an environmentally enclosed housing or dome. The advantages and disadvantages of these two techniques are discussed.

Complete integrated video camera/lens/pan/tilt/ housing systems have been introduced, in which all these parts are integrated into a custom housing or dome. Typical systems are discussed in the following sections. In a parking lot or building exterior, pan/tilt lens/ camera systems are mounted on a pedestal or on a wall or ceiling, with mounting brackets. For covert applications, all pan/tilt and zoom camera/lens hardware is hidden behind a wall or ceiling. The transmission of the video signal and the control of pan/tilt mechanism movement and lens function are accomplished through separate video and control cables or through a multiplexed communication channel where the video signal and the controls are combined on a single coaxial cable or UTP, thereby eliminating additional wiring.

Scene coverage required

The intelligence the security guard obtains from the monitor picture is only as good as the information the camera/ lens combination sees. It is therefore important to determine the viewing requirements of each camera/lens and select the optimum combination for transmitting maximum intelligence to the operator. The video system designer must decide whether a camera will be mounted on a fixed mount (pointed in only one direction), or on a pan, tilt, or pan/tilt platform so that the camera can be pointed in any direction.

A good analogy is the seeing ability of a human: when we look in a single direction, we see all of the activity in that direction all of the time. When we move our eyes or head in another direction within a large FOV, we cannot see the entire scene at one time, and therefore cannot see all of the activity in the entire FOV that our eyes can see. The 3G Wi-Fi Camera in essence time shares the viewing of the scene, spending a fraction of time looking at any particular portion of the total scene area. In order to analyze this viewing requirement, video applications are divided into three types: point, area, and volume.
Point Scenes

A typical security surveillance point scene might be a supermarket checkout line, where the information of interest is the merchandise being rung up, the amount displayed on the cash register, the cashier, and the customer; or the scene might be a bank teller station, where the crucial intelligence is the identity of the customer. In such scenes, all of the activity occurs in a relatively small part of the FOV. Although a single camera with an FFL lens may be satisfactory, a better solution might be a fixed two-lens, one-camera system, with one lens viewing the amount rung up on the cash register and the other viewing the cashier, customer, and merchandise. Another solution is a zoom lens with some panning and tilting motion. This would be necessary in a jewelry or department store where the counter area is viewed with a wide-angle lens and a small piece of jewelry is viewed with a narrow-angle lens. The pan/tilt is necessary with a zoom lens because the high-magnification (telephoto) position results in a very small FOV, so the camera must be pointed at the exact center of the target.
In the wide-field scene, the article of interest is not normally centered in the FOV. In this situation, the operator must redirect the camera/lens combination via the pan/tilt control to center the object of interest and make it observable in the high-magnification position

The future of Wireless Home Monitor technology

I don’t know about you, but most people would jump at the chance to automate more things in their lives if doing so were affordable and could be achieved with reasonably minimal effort. Well, you’re in luck. Most of us are able to automate at least certain aspects of home life today because they don’t cost an arm or a leg, and they aren’t difficult to install. This blog focuses on how you can simply and relatively inexpensively control many of your daily tasks. Not only that, most of what I cover can be handled remotely, meaning you don’t even have to be at home to do this awesome stuff.
Today, all you need to implement a home automation system is an Internet connection and (in some cases, but not all) a device to control it, such as a smartphone, table, or computer. Of course, you have to purchase a system or appliances, but many of them that utilize your Wi-Fi network (or even your home’s power lines) are inexpensive. Another bonus with today’s home automation technology is that you can start as small as you like and build up to as large as you like. For example, with a kit such as the WeMo Switch + Motion kit from Belkin, you can begin with just a smart wall outlet and a motion detector, but can add more and more WeMo devices to your heart’s content.

Benefitting from Wireless Home Monitoring

The idea of home automation is really cool and futuristic, but if that’s your only motivation to automate the things in your home, you just might be missing the forest for the trees. Sure, you can impress friends by turning on your fireplace with a tap of your iPhone, but benefits of home automation go way beyond bragging rights.

Convenience is key!

Convenience is indeed the key; otherwise, what’s truly the point? The words “home” and “automation” fit together perfectly to describe how to get things done easier, better, and faster than ever before, which equates to convenience. Want a few examples of how today’s home automation is convenient? Okay, here you go:

✓ Your teenage son calls from a friend’s cellphone and tells you he’s locked his keys and everything else he owns in the car you let him borrow. This kid is 30 minutes away — not good. Suddenly you remember you had installed a device in your car that enables you to unlock it (and even start it) from a million miles away with your smartphone. A few taps and swipes on your phone, and your son is back in the car. Convenience.

Wireless Home Cameras

✓ The lawn needs mowing before company arrives this weekend, but you’ve been in meetings all week on the other side of the country, and now you’re stuck in the airport. Whip out your Android phone, open your robotic lawn mower’s app, and tell it to get to work. The lawn’s done before your plane even lands. Convenience.

✓ You and the family are singing “Let It Go” of Frozen fame for the 100th time on your road trip to Disney World when it dawns on you (three hours away from home) that you left the lights on and an electric heater running in the bathroom. You calmly fire up your iOS tablet, open the app for your home automation system, and turn off the lights and the outlet the heater is plugged in to. Dare I use the “C” word again? You bet I do. Convenience.

Security

Fewer things in life are more appreciated than security — in this case, knowing (or at least feeling) that you’re more safe doing things a certain way or using certain devices. Today’s Internet-based home automation technology gives one just that kind of security. Sure, home security companies have been in existence for decades now, and they are great at what they do. People also have had personal means of protection that usually work as intended, provided they’re used properly. Wireless Security Cameras have also been providing more home security for some time, although they typically were expensive to install. With today’s tech,however, you can secure your home in myriad ways you never were able to before:

3G Wi-Fi Camera provide a look into your home from anywhere you have an Internet connection.

✓ Motion detectors keep you privy to any activity in your home.

✓ Smart locks and security apps allow you to lock and unlock your doors, no matter whether you’re home or visiting family halfway around the globe.

✓ When coupled with the use of door and window sensors, apps can alert you via text or email when someone enters your home uninvited.

✓ You can control lighting within your home from anywhere you have a connection to the Internet, making it appear to folks outside that someone is home. And these are just some of the things that Internet-enabled home automation systems and devices can do to help raise your level of personal and family security.

Rearview Mirror Camera and 3G GPS tracker technology

Rear View Mirror Camera , also known as car DVRs, record while you’re driving so you have evidence if anything happens.

In either case, the device draws power from a wired 12-volt connection to the car. JC900’s low power protection mechanism would prevent the battery from being dragged out when power is too low.

3G GPS tracker technology 

For many years GPS tracking devices have operated on 2G networks to transmit location data, and for simple black box solutions that only need to send small amounts of data this system has worked well. But to understand the necessity of a switch from 2G to 3G, it’s important to understand the major benefits the newer generation networks bring. Perhaps the biggest change 3G brings is the pure bump in data transfer rates. While 2G download and upload speeds capped performance at about 236Kbps, 3G can reach rates as high as 21 Mbps (nearly 90x faster than 2G). This is essential to compensate for the increased amount of data tracking that devices can be programmed to capture and transmit beyond just location, things like: ignition statuses, harsh braking events, vehicle performance information, speed data, odometer data and more.

Wireless IP Camera buying guide – From Image Quality to Progressive scan

How to select best Wireless Camera ? I know you may read many articles about this topic, but I’d like to share my some thoughts on this selection of Wireless Camera. Choosing the appropriate IP camera including many factors. IP cameras are widely used in many fields including industrial, military, civilian…etc. Today, we are going to narrow its scope, and merely discussing the selection of IP cameras for home. No perfect solution, only good camera to meet your needs, let me share my thoughts.
There are biggest 7 factors you should consider when choosing a Wireless IP Camera:

1. Image quality

Image quality is the most important feature of any camera. This is particularly so in surveillance and monitoring applications, where lives and property may be at stake. Superior image quality enables users to more closely follow details and changes in images, making for better and faster decisions. It also ensures greater accuracy for automated analysis and alarm tools, such as object recognition. When assessing image quality be sure to research the following factors: light sensitivity, the crispness of moving objects, and the clarity level. A camera’s datasheet will tell part of the story, but it is a good idea to field test a few cameras before making a decision. In addition, there are some simple steps you can take to ensure high quality images – use enough light, avoid backlight and reduce contrast whenever possible. It is also critical to take into account the location of the cameras, especially if the cameras will be used outdoors. An auto iris lens, which automatically adjusts the amount of light that reaches the image sensor, should always be used for outdoor applications. Direct sunlight should always be avoided. Mount the camera high above the ground to avoid a contrast effect from the sky. If the camera is mounted behind glass, the lens must be placed close to the glass to avoid reflections.

2. Power over Ethernet (PoE) 
In most buildings today, TCP/IP infrastructure is available by means of Cat 5 and 6 cabling. The cabling can be used for fast transport of data, and the distribution of power to devices connected to the network, using PoE technology. PoE reduces installation costs by eliminating the need for power outlets at the camera locations and enables easier application of uninterruptible power supplies (UPS) to ensure continual operation, even during a power outage. PoE technology is regulated by the IEEE 802.3af standard and is designed to not degrade the network data communication performance. When evaluating PoE-enabled network cameras, it is important to look for those that are based on the IEEE standard, to ensure that any brand network switch can be chosen, providing a truly open system.

3. Progressive scan

Progressive scan capability is found only in network cameras,but not all network cameras have this functionality. Progressive scan involves exposing and capturing the entire image simultaneously, as opposed to analog interlaced scanning which is the exposing and capturing of only half of the lines in the image and then the other half 17msec later. With interlaced scanning, if an object is moving the image will become blurry. In a progressive scan image all lines are scanned in perfect order so there is virtually no “flickering” effect. While interlaced scanning may be sufficient under certain conditions, progressive scan technology allows for far better image quality on moving objects. In a surveillance application, this can be critical in enabling the user to view detail within a moving image such as a person running away or the license plate on a moving vehicle. When cameras capture moving objects, the sharpness of the frozen images depend on the technology used, and progressive scanning consistently produces the best results in clarity and recognizing important details.

4. JPEG/MPEG4 standardsIt is important for any network camera to follow JPEG and MPEG-4 standards in their entirety. Many vendors claim compliance with a standard, but do not adhere to that standard 100 percent. Full adherence ensures the flexibility to use video for many different applications. It also guarantees that you can view the video many years from now. If a camera uses one company’s proprietary compression technology and that company goes out of business, the video will be unreadable in the future. Also, if a company is following the MPEG-4 standards, ask if the licensing fees are paid, and how many licenses are included with each product. Proprietary compression technologies are also not always admissible in court, an im portant consideration for security and surveillance applications.

5. Day or night surveillance
Certainly, you want the camera watch your home at day/night. A day/night IP cam can provide you color images at day, and B/W (Black and White) images at night. What does make camera see at night? Typically, similar to our human eyes, camera also can’t see under complete darkness. The camera utilizes infrared illuminator to help them see at night. Infrared light is invisible light for human being, but image sensor can see, with this feature, it becomes ideal light sources for cameras. How far the illumination of Infrared determines the night vision range. For interior protection, the night vision range shouldn’t less than 5 meters, 10 meters is the minimum range for outdoor monitoring.
6. Extensive support of Video Management Applications 

The security industry migration to network video includes the use of open systems and platforms. Make sure to select a network camera that has open interfaces (an API or Application Programming Interface), which enables a large variety of software vendors to write programs for the cameras. This will increase your choices in software applications and will ensure that you are not tied to a single vendor. Your choice of network camera should never limit vendor options and functionalities.

7. Audio
If audio is required, consider whether one- or two-way audio is needed. Axis network cameras with audio support come with a built-in microphone and/or an input for an external microphone and a speaker or a line out for external speakers. Integrating audio into a surveillance system makes it possible for personnel to hear and speak with possible perpetrators. It can be easily integrated with video management systems. From a surveillance point of view it can also be used as an independent detection method triggering recordings and alarms when audio passes a certain threshold.

Below is one of the most popular Wireless Security Cameras on the market.

JH08 Wireless IP Camera allows you to view your home on the monitor or remotely from anywhere in the world on a computer or smart phone, giving you instant monitoring from your Phone or Pad. It also offers both sound and motion sensors. Users can set the system to automatically record footage upon activation of the sensors.One wireless IP camera is equivalent to a set of CCTV system.

How to select best Rearview Mirror Camera for your car

Rearview Mirror Camera technology is a fantastic safety feature in any car, so much so that by 2018 all new cars must be fitted with these units. From hooking up your trailer, reversing into a tight parking spot or just making sure your kid is not behind your car when you reverse, these units will make the job so easy. If you are in the market for a new rear view camera there are some pitfalls that will cause serious buyers remorse so this guide should make your decision much more informed and easier.
The biggest factor in choosing a rear view camera is how much can you see. So your biggest 5 factors are:
1. Automatic System Switching
Possibly the most important feature to look for when purchasing a rear view camera system, is that system’s ability to switch on automatically whenever the vehicle’s transmission is placed in reverse. This is accomplished by connecting a single wire to the vehicle’s backup light circuit, sending a signal to the rear view camera system, causing it to switch on without any action by the operator.Many so-called ‘rear view camera systems‘ don’t have this feature, and will require you to manually switch the system on every time you want to see behind you. The higher end systems will have this ability to switch on automatically, in addition to being turned on manually any time using the monitor’s front panel power button (or wireless remote control, if so equipped). Since it’s very inconvenient and extremely unsafe for the motor vehicle operator to be required to switch the system on manually every time he or she wants to back up, it’s imperative that you never purchase a rear view camera system without the ability to switch on automatically. If the system you’re considering doesn’t clearly list this feature, it almost certainly doesn’t have this feature. Never purchase a rear view camera system without this feature.
2. Field of View
The field of view of the camera is determined by a number of factors like the image sensor size, type and the lens focal length. Like a normal camera the bigger the sensor the better the quality of the picture, the better it performs in low light and the wider the field of view it can achieve. A 1/4” sensor can only deliver a 60 to 90 deg field of view while a 1/3” should deliver around 120deg.
90deg is the minimum field of view you should accept, but seeing there are so many units that perform better I would not purchase anything less than 120 deg. 1/3” image sensor and a 120 deg field of view should be your baseline. There are super wide-angle units of 180 and even 210 on the market. Sounds grea,t but these units create a fisheye lens effect and it is virtually impossible to use them to reverse. Imagine reversing by looking through the peephole in your front door, you are guaranteed to have an accident at some point.
3. Screen Size
No matter which rear view mirror camera system display you choose, it’s likely to be smaller than some of the standalone models just because the display has to fit inside the dimensions of the mirror.  A smaller display makes it more difficult to see the details in the image which are important in the case of a back up camera display.  Look for a monitor size in the mirror of at least 4.3 inches in order to get the best image possible.
4. Video Inputs
Some cameras come with multiple video inputs that can handle the inputs of both a car rear view camera and a car DVD player for instance.  If that’s important to you, look for dual video inputs on any display you buy.
5. Bluetooth Hands-Free

Some displays come with additional options that can be very helpful including Bluetooth hands-free capability. Bluetooth hands-free model can be connected to a Bluetooth-capable smartphone so that you can use your phone without taking your hands off the wheel.  It’s a great safety feature and one that can prevent you from getting a ticket in states where hands-free is required.

How parents Can Benefit from GPS Kids Phone

It’s not new in a country where people take advantage of GPS-enabled cell phones to keep tabs of their loved ones’ whereabouts. Personal GPS Tracker have been known to not work very well indoors and generally give the pinpoint accuracy of a few yards–not good enough to indicate definite physical contact. Thanks to modern technology, cell phones can now be tracked by a GPS chip. Today, GPS tracking and reporting technology is integrated into every device from smartphones to sneakers and watches. As this emerging technology goes mainstream, parents are starting to rely on GPS to ensure the safety and security of their children on their way to school.

How Will It Benefit Schools?

The heightened concern nationwide about security in the wake of campus shootings and other high-profile incidents, combined with the technical abilities of smart phones, is driving the creation and demand for the safety apps. Campus police are praising some of the apps for creating a new trove of incident alerts and detailed tips, complete with GPS coordinates, detailed physical descriptions, and photos of potential lawbreakers or license plates.It makes perfect sense to have GPS tracking technology installed in school buses to aid in the safety of children and drivers. Parents can receive text messages when their children are approaching the bus stop or when the school bus reaches a certain distance. Parents can also be notified when a child has reached the bus stop and is ready to be picked up.

School districts and authorities can benefit from school buses equipped with GPS tracking devices in several ways. With GPS tracking, they can reduce fuel costs, review time punches and ensure the safety of students. A GPS equipped school bus has the ability to map out the most efficient route for the bus driver, avoiding wrong turns or high traffic areas. This results in significant fuel savings since the bus driver would be traveling the shortest route possible. It also means immediate ROI since school districts can save money on paying bus drivers because travel time is greatly reduced.

GPS Tracker Device can help protect children from being abducted. Since cases of missing children are on the rise, utilizing tracking technology to help keep children safe is a benefit to both school officials and parents. A good GPS tracking device can confirm whether a child was on an assigned bus and if they got off the bus. Knowing that a child is on their assigned bus and traveling to the right location provides assurance to parents and can help law enforcement authorities in the event that the child was not where they were supposed to be.
