6 Troubleshooting
6.1 Camera Rebooting / Turning Off
A. Check the voltage ofthe camera (under load) ifbelow 10.8V thenmove the power supply
closer to the camera.
B. For 12V DC cameras only ever use regulated power supply rated at above 750mA, 1A
would be recommended. So that the camera is always receiving the correct supply.
C. Use thicker gauge copper cabling to reduce the voltage drop.
6.2 Poor Quality Images
A. Check the fly-lead is set to the correct output – see 4-In-1 Technology
B. Ifset to CVBS, thenthis is a low quality video output for legacysystems (Analogue), when
using a 5 MegaPixelDVR or above thenuse another video format, like HD-TVI.
C. Reset the camera menu via Zip Coaxitron – OSD Menu
D. Check ifyour DVR supports 5 MegaPixelcameras.
6.3 Image is Black & White
A. Check the video format your DVR supports, thenset the camera to the relevant video format
– see the 4-In-1 Technology
B. Reset the camera menuvia Zip Coaxitron OSD Menu
C. Check the recorder supports 5 MegaPixelcameras.
6.4 NCD / No Image Displayed on Recorder
A. Test that the camera has the correct voltage supplying it, this must be done with the camera
connected so that there is load on the PSU. A 12V DC camera should have at least 10.5V DC
connected to it.
B. The camera cannot function without the correct power supply. For 12V DC cameras only
ever use regulated power supplies to ensure that the camera is always receiving the correct
voltage.
C. Ensure that the BNC – BNC lead that is connected between the camera and DVR has no
shorts or open circuits.
