Monitors for CCTV home security systems
![]() |
The monitor receives the transmitted
electronic video signal from the camera and displays the image
using a cathode ray tube
(CRT). Although similar in function to a TV set, a CCTV monitor
provides higher lines of resolution (better picture quality) and
accepts only video signals rather than RF/antenna signals. |

Lines of resolution refer to the total number of horizontal lines the camera or monitor is able to reproduce. The more lines on a screen, the better or sharper the video picture will appear. CCTV monitors can provide up to 1000 lines of resolution compared to an average of 300 lines provided by television sets. Several factors can affect the monitoring function: Size of the monitor (9" and 14" are popular sizes), its positioning and angle relative to where the viewer sits, the quantity of monitors, and the quality (resolution) of the monitor itself. In all cases, sufficient growth must be factored into any console design. It's also important to note that all monitors generate heat. Whether on a table or enclosed in a console, be sure to provide adequate ventilation and air-conditioning. Most CCTV systems use both dedicated monitors and switch able monitors. A dedicated monitor displays the video from only one camera. A switch able monitor enables operators to "call or switch" different cameras to the monitor. |
