GeoVision DVR Conflics & Possible Resolutions

No/Poor/blurred image on a camera

• On the box camera body, where the lens attaches to the camera body, make sure the big outer silver ring is removed. Only the small inner silver ring is required.
• Make sure the DC switch in the back of the camera is set to DC or AI-AMP, depending on the camera model and manufacturer.
• Make sure, if using an auto-iris lens, the 4 pin power cord is properly inserted in the 4 pin switch in the back of the camera.
• If you still have no image, or black screen, or even ‘ Video Lost,” you may have a bad channel on the DVR card. Move the video cable to another channel to see if the issue is the camera or the card.
• Try Refocusing the lens
• Ensure the lens is tightened ONLY finger tight
• Insure the correct version of octopus cable/dongle (the cable connected to the PC-DVR in the back of the PC) is attached to the DVR card
• An external light source or object that may reflect light into an IR camera can cause the image to “wash out” insure that there is no light from streets or external building lamps. If placed near a wall or roof overhang have enough clearance not to get a reflection into the lenses of the camera.
