Step 5Wiring the video camera

wiring the video camera
the video camera takes a 12V line and gives a video signal.

Cut and strip the wires coming out of the bullet camera. Cut near the connectors to leave lots of extra wire.
Under the insulation there should be 4 distinct wires. The red and black pair are for power, and the other two (yellow and black or insulated and not insulated ?) are for video.

+ the 12V line +
Cut and strip the ends of a battery pack. Use a multimeter to find the positive (+) and negative (-) lines coming out of the battery pack. Label the lines in some way so that you don't forget. On the connector match the (+) coming out of the battery with the red line on the camera, and the (-) with black.
The camera power lines connect to the connxall end piece, and the battery pack connect to the connxall wall mount piece.

+ the video signal +
The a/v cable should have 3 RCA connectors - red, white, and yellow. The yellow one is for video. Cut the a/v cable at a length that the connection to the camera will fit nicely in the box. The color theme will prevail inside the cut a/v cable.
The video signal (yellow and black pair) from the camera goes on the connxall end piece, and the video signal in the a/v cable goes on the connxall wall mount piece.

The picture shows the a/v cable (on the right) connected to both video and audio connectors. The camera is attached, microphone unpictured.
