How Does Home Video Surveillance Work?
It used to be the case that video surveillance systems were only used by businesses large enough to afford them. As prices have come down, they have become increasingly popular among homeowners. A home video surveillance system such as CCTV (closed circuit TV) can provide security against threats such as burglars by monitoring vulnerable areas.
The viewing monitor is a key element of the home video surveillance system. The monitor will display video images from the cameras. The images are usually black and white and of a higher resolution than that of an analog television set - typically between 500 and 1000 lines.
The video surveillance cameras are also an important component. When setting up the home surveillance system, the cameras are installed strategically around the outside of the home, in the most vulnerable locations. They should be placed where they are hidden or difficult to see. The cameras are always running, transmitting video to the monitors on an ongoing basis. To be effective at night, you will need either lighting or infrared security cameras which can monitor in complete darkness.
Unless you use a wireless security system, coaxial cables are also necessary for video surveillance systems. The coaxial cables transfer the video signals from the camera to the monitor. These cables are available in a variety of sizes and can be found at home security suppliers and electronics stores. Your home security system will come with coaxial cables, although you may need more depending on where you plan to set up your cameras.
Home video surveillance system also need switchers. Switchers permit you to transmit multiple camera feeds to one monitor. Normally, a switcher will cycle through the feeds unless movement is detected at a specific motion sensor security camera. When the switcher detects any movement, it will automatically lock on to the camera which observed the movement.
There are some home video surveillance systems that utilize video recorders to record any live video feed that you program. This can be useful if you travel a lot, as the recorder can capture a break in as it occurs. If the case goes to court or to the police, you can use the video recording as evidence. Video recorders can catch burglars in the act - especially if you locate the camera where it is hard to spot.
A monitor and video surveillance cameras can be combined so that home video surveillance systems can be used to easily detect burglaries and break-in’s. They are being used in thousands of homes across North America and have become quite affordable. If you are in search of the best way to secure your home- a home video surveillance system is definitely worth being checked out.
