DVR's (Digital Video Recorders) replace VCR's, and Multiplexers with a Computer based system and require little Maintenance. A high resolution Monitor is recommended to allow you to see the quality of the live images and recorded video. A UPS is recommended to protect the system against fluctuations in power.

 Cameras need little Maintenance other than regular cleaning to keep dust & dirt off the lenses & camera body. Cameras should almost always be in a housing to help protect them from the elements & damage.

 Camera power supplies are one of the first things to check when you are experiencing camera problems. If back-up batteries are used they have to be replaced every 3 to 5 years.

 Monitors should always be turned off when not being viewed, this helps extend the life of the monitor and helps prevent screen burn.

 Overall, CCTV equipment should be kept away from excessive heat, cold, moisture or corrosive environments unless you are using equipment specifically designed for that environment.
