Security First 5005 camera wire pinout

Security First (which seems to be no more) 5005 cameras use RJ11 6 pin connectors. Their pinouts are as shown in this diagram.

The wires in the connector and 100 foot cable are Red white black black. pin 5 may be yellow in the 100 foot cable. the colors in the diagram are from the camera.

the wires internally to the camera are Red white black yellow.

Information I can find states the red wire can accept 12-15vdc which means that it probably has a voltage regulator in side and is compensating for the massive voltage drop through 100 feet of very small wire.

I have no other information than what is presented here.
