Wireless
security camera systems are used on large estates, farms in the countryside and
in large buildings or multi-storeyed blocks that are difficult to keep secured
and safe. The wireless security camera systems consist of a wireless digital camera that can be installed
anywhere. It sends continuous pictures to a monitor which can be placed at a
distance from the camera in a secured room from where surveillance can be done.
The system can have more than one camera and the output of these cameras is
shown serially after a fixed interval of time.
Thus
the monitor will show the output of camera 1 followed by camera 2 followed by
camera 3 etc. in sequence, each output showing for about 15 to 20 seconds. At
the same time the recorder records the output of all the cameras and it can be
played back whenever there is a need to do so. The recording for about two
weeks or more is saved and after 2 weeks, the current
recording is written over the old one. Usually the wireless security camera
systems are well built and hardly need any maintenance. They are used all over
the country by farms and estates in the rural countryside and by large
buildings and housing colonies as well as commercial spaces.
