Troubleshooting
7.1 Camera Rebooting / Turning Off
A. Check the voltage to the camera (under load) using a digitalmulti-meter, ifbelow 10.8V then
move the power supply closer to the camera.
B. For 12V DC cameras, only use regulated power supply rated above the current consumption,
so that the camera is always receiving the correct supply whichis rated above the current
consumption.
C. Use thicker gauge copper cablingto reduce the voltage drop to the camera, using thicker
cable willreduce the resistance betweenthe camera and the power supply and therefore reduce
the voltage dropped along the cable.
7.2 Poor Quality Images
A. Check the video format the DVR (digitalvideo recorder), then set the camera to the relevant
video format – see the 4-In-1 Technology
B. Ifset to CVBS, then this is a low quality video output for legacy systems (analogue - CVBS),
when usinga 2 MegaPixelDVR or above then use another video format, like HD-TVI.
C. Reset the camera menuvia Zip Coaxitron – OSD Menu
D. Check ifthe DVR (digitalvideo recorder) supports the resolutionofthe camera.
7.3 Image is Black & White
A. Check the video format your DVR supports, then set the camera to the relevant video format
– see the 4-In-1 Technology
B. Reset the camera menuvia Zip Coaxitron OSD Menu
D. Check ifthe DVR (digitalvideo recorder) supports the resolutionofthe camera.
7.4 NCD / No Image Displayed on Recorder
A. Check the voltage to the camera (under load) using a digitalmulti-meter, ifbelow 10.8V then
move the power supply closer to the camera.
B. For 12V DC cameras, only use regulated power supply rated above the current consumption,
so that the camera is always receiving the correct supply whichis rated above the current
consumption.
