Cameras For Home Video Surveillance Systems
When it was first introduced, video surveillance systems were used primarily by medium to large businesses. Currently however, they are becoming much more common in homes. video surveillance security systems are also known as closed circuit TV (CCTV) and are used to monitor vulnerable areas around the home to provide protection from burglars and other threats.
A viewing monitor is a key component in a home video surveillance system. Such a monitor displays video images from cameras. These images are often black and white and will have a much higher resolution than the images from an analog TV set - say, from 500-1000 lines.
The 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.
A requirement of a video surveillance system, other than a wireless system, is a coaxial cable. These cables transmit video signals from the camera to a monitor. You can get many different kinds and sizes and find one that's right for your equipment at most security suppliers and electronics stores. While your home security system will come with coaxial cables, the location and set-up of your system might mean you need more.
A home video surveillance system should be controlled by switchers. The switches allow one monitor to show feeds from multiple cameras. If movement is detected by a motion sensor in one of the cameras, the switcher will lock the onto that camera feed. Otherwise, the switcher will cycle through each feed in turn.
Many home video surveillance setups use video recorders so that their live video feeds can be recorded and kept for future reference. If you travel or go on vacation, the recorder will see any break in that happens. If the burglar is arrested and goes to trial, the video recording makes excellent evidence against him or her. A video recorder in an inconspicuous spot, difficult to access, can ensure that burglars won't get away clean.
By combining a monitor and video surveillance cameras, home video surveillance systems can easily catch burglaries and break-in's. They are quite affordable these days, and are in use in thousands of homes throughout North America. If you're looking for the ideal way to protect your home - a home video surveillance system is certainly something you should check out.
