This is the latest in technology, the cameras are viewed in 5 megapixel and requires coaxial cable. This is an affordable way for upgrades of older CCTV systems as analogue systems where the norm until the ip revolution. Any system with existing coax cable can now be upgraded to true HD images ranging from 1080HD to 8 megapixel. The newest solution is POC [power over coax] the one coax cable can now feed the data and power meaning no power supplies.


The cameras are wired in coax cable and the maximum resolution is well below 1 mega pixel .Analogue video has been a universal standard for several decades and is now extremely affordable but is being phased out and HD analogue will soon become standard.
