Abstract
An audio/video surveillance recording system comprising both units having a video camera and units having a dummy lens is disclosed. The use of a dummy lens rather than tinted or mirrored glass on the camera housing provides a greater amount of light to the camera. A unique mounting assembly which lets the dummy units be substituted for the live units without removing the mounting brackets is also disclosed. Both the dummy and live units have illuminated indicators. The system uses weatherproof microphones manufactured using a novel plastic dipping and coating method.
