Home Video Surveillance–Peace of Mind through Wireless Technology
Home video surveillance used to be a costly and time-consuming project–but not anymore. A homeowner who is away on holiday or at work while contractors in her house can now access the webcam external feed via an IP address to see if something is wrong. Parents can watch that their child’s nanny and property owners can ensure that their rental properties are safe and secure with best rates guaranteed.
Home video security systems can count on wireless IP technologies, wireless sensors and webcam surveillance in order to meet the security needs for each homeowner budget. It is estimated that more than half of home monitoring systems purchased today are using wireless technologies. Jeff Hoover, says the past President of the Custom Electronics Design and installation Association, “as video systems get better and cheaper, more and more people begin to use them.”
Before the popularity of the webcam, tiny spy cameras or wireless video cameras, were the only option for cheap home monitoring. Price between $ 130 to $ 500, send these cameras their video signals (434 MHz, 900 MHz or 2.4 GHz) and a local base station. From there, the images can then be displayed on a TV, mobile phone, PDA, laptop or desktop computer. This surveillance cameras, which can be hidden in the clocks and smoke detectors, be bought to watch in the home, sometimes without their knowledge to patronize. Unfortunately, if the cameras in the low-end price points, there is a greater chance that their wireless signals can be picked up by “war-drivers,” that cruise the streets trying to hack into homeowners wireless signals. However, the higher-end cameras provide encrypted transmission and tie in standard WiFi networks.
SVAT electronics of Niagara Falls, Ontario, is the new GX5150 Baby Monitor home surveillance system with a tilting screen plus night vision equipped with eight infrared led lights to light up the baby in the blackness preview. Additionally, it is GX5400-system a nanny-cam that contains a memory card, and connects up to four cameras simultaneously, so that parents their cameras images via a personal Internet IP address control.
On the high side of the consumer products is home surveillance market the Smartvue S2. This system works with the pre-standard with WiFi 802. 11n, with which the cameras to send signals to a base station up to 800 metres away. The images of this wireless IP camera are extremely sharp (720 x 480 pixels) and deliver a frame rate of 30 images per second. The camera can also be used for low light conditions.
Motorola offers the Easy Start Kit HMEZ1000, priced at $ 280. The Easy Start comes with two movement and sound-detection cameras, along with sensors that the homeowner a warning if a door is open, if there is a leak, if there are temperature fluctuations, or if someone is approaching the front door. Once the images are included, they are sent through a broadband connection with a computer, PDA or mobile phone. Homeowners can also buy motion sensors without cameras that thoughtful the homeowner to intruders with high-frequency radio signals. In other sensor systems, infrared light is applied to the heat.
With a webcam surveillance system detects software, such as EvoCam (for Mac users) and TinCam (for PC users) movement, so that recording only occurs when something in movement for the motion sensors. The webcam does this by capturing two images, and then compare them for differences. This set-up saves space on hard disk memory and time because the images are per email sent directly to the user. These software applications allow the user to host the images via the built-in web server so that he or she can easily access them via a static IP address can also. The user must not forget to set up a port on the firewall to see the images.
Some of the disadvantages of the use of webcams for homeland security include their fixed positions that limit their reach, and the fact that they are USB devices that can not more than 16 feet away from the computer or the USB hub. In addition, perform webcams not generally well under low-light conditions compared to most wireless IP video cameras, so one should not forget to switch on a light for extra lighting.
Today, homeowners can choose from a variety of home monitoring options that give a sense of security when they are away from home. If there are any problems, they know that they will be alerted quickly. Home surveillance technology will only get smaller, faster and more reliable within the next few years, such as computers and cameras work together to ensure security with a touch of a button.
