Being aware of the basics of CCTV camera operation will help you solve problematic systems effectively. A CCTV camera makes synchronization pulses to make a picture be locked on the viewing monitor on the picture. 15,750 times per second is the rate these pulses occur. There is 1 sync pulse for every line in the screen frame. The sync pulse tells the video monitor to start drawing a video line across the picture screen. When it gets to the end of the screen, another synchronization pulse begins the next line until the screen has been filled. It takes 262 [fraction one-half] lines to form a frame and two frames to form the video picture seen on the monitor.
