About CCTV Test Monitor
Closed Circuit Television has revolutionised and simplified the protection of homes, businesses and public buildings. As with all security devices CCTV systems need testing and, to carry out comprehensive testing a good CCTV test monitor is essential.
Today?s CCTV test monitors are lightweight, well equipped and battery powered. Most power units are lithium based and usually provide for approximately 4 hours of usage between charges.
The more sophisticated CCTV test monitors can analyse and test both digital and analogue equipment, the more basic units being analogue only. To be really effective, units should support RS232 ,RS485 and RS422 interfaces and baud rates ranging from 150, 600 to 19200bps.
Liquid crystal display monitor screens are normally 3.5? though some are smaller, typically 2.8?. LCD brightness, contrast and colour saturation should be adjustable in order to accommodate different environments and lighting conditions. The cost of CCTV test monitors has dropped dramatically over the years but generally speaking and as with most items, higher priced products offer more facilities and sometimes greater reliability.
As with most electronic items, it is advisable to purchase a suitable case for the test monitor in order to protect it from the elements as well as from general wear and tear. Carry cases should have a shoulder strap to facilitate ease of use.
CCTV installations use different protocols and CCTV test monitors should accommodate as many as possible, including PELCO-P, PELCO-D, SAMSUNG etc. Some more advanced CCTV test monitors are able to analyse and assess audio as well as visual input and the most sophisticated units are able to test video feeds as well. These CCTV test monitors are also capable of testing dome cameras and all-in-one camera units.
