A closed circuit television (CCTV) security camera is a good way to ensure safety in a public building, but as with any type of electronic equipment, there are possible performance problems. Such issues include the camera not sending images to the monitoring station, sending blurry images and images flickering on the monitor. Depending on the problem you encounter, there are several solutions.


Step One

Picture Not Displayed on Monitor -Check the main power cord. If it is not securely plugged into an AC outlet, plug it in.


Step Two

Check the cables. If any of the cables is loose or disconnected, securely reconnect it.


Step Three

Check the IRIS mode select switch. If you are using a DC driven auto iris lens, it should be set to "DC" mode. If using a video driven auto iris lens, it should be set to "VI" mode.


Step Four

Blurry Image - Check the camera's lens for dirt or other contaminants. Use a soft cloth to clean both sides of the lens.


Step Five

Adjust the focus on the lens until the picture on the monitor comes in clearly.


Step Six

Set the iris select switch to "ES" mode if you are using a manual iris lens.


Step Seven

Flickering Images - Adjust the direction if the camera is facing fluorescent lighting or an area with too much sunlight, as these can cause interference with images.


Step Eight

Check the iris mode select switch. If you are using a DC driven auto iris lens, it should be set to "DC" mode. If using a video driven auto iris lens, it should be set to "VI" mode.


Step Nine

Set the iris select switch to "ES" mode if you are using a manual iris lens.
