Closed Circuit TeleVision or CCTV security camera systems are fast becoming the most popular means of security for residential and commercial applications. Thanks to modern technology these systems are incredibly versatile and reasonably priced.
CCTV security camera systems are available with 4, 8, 16, or 32 cameras. These systems are not required to use the number of cameras specified; in other words this is the maximum number of cameras the system can handle. So if your security system design calls for seven cameras you will require an 8 camera (also called “channel” CCTV security camera system).
