C. Use thicker gauge copper cabling to reduce the voltage drop to the camera, using thicker
cable will reduce the resistance between the camera and the power supply and therefore reduce
the voltage dropped along the cable.
D. Ensure that the BNC – BNC lead that is connected between the camera and DVR has no
shorts between the ground and the centre core (positive) or open circuits along the centre core
(positive) or open circuits along the ground.
General Maintenance
Routinely clean the camera to prevent dust build up as this can effect the performance of the
camera. It is recommended to use a damp non-abrasive microfibre cloth.
Routinely check the connections for power and data to ensure no water ingress and corrosion.
Check that the cameras are firmly attached to the wall or mounting bracket.
Check playback in the recorder to ensure the camera is recording and triggering properly.
