Closed-circuit television surveillance cameras have been recording video in black and white because color cameras couldn’t match black-and-white cameras’ sensitivity to light. Recent electronic advances now enable CCTV color cameras to capture color as well as black-and-white cameras do, but if the color is not accurate, the image is hard to see. Adjusting CCTV color cameras so that they properly display color is a necessity for them to function at their optimal setting.
Things You’ll Need : 10 megahertz oscilloscope, Video equalizer
- Adjust the level of the synch pulse amplitude on the CCTV color camera to 40 Institute of Radio Engineers (IRE) units. View the image of the CCTV color camera to see if the picture is breaking up or rolling. If the picture is breaking up or rolling, readjust the synch pulse amplitude to a higher number and view the picture again. Stop adjusting the synch pulse amplitude when the picture on the monitor is no longer breaking up or rolling.
