Power connections
An external DC power supply may be connected to pins 1 and 2 of the external connector. Make sure the power supply meets the requirements outlined in Appendix B. When the external power connections are used, the internal power selector switch must be set properly. Do not reverse power supply leads; the camera will be damaged.
External trigger operation
The external trigger line allows the camera to be activated by an external switch closure (door/gate switch or a motion detector). The operation is the same in both AUTO and ON power modes, except in AUTO mode the camera will automatically turn on and off in response to the trigger signal, conserving battery power. The camera is always powered in the ON mode. The external trigger function is always available; no configuration settings are required. Do not connect to this signal if this function is not required.
The external trigger line must be switched to the ‘return’ line for a minimum of 300 milliseconds to activate the camera. In AUTO mode the external trigger must be released from the ‘return’ connection before the camera will turn back off. If the external trigger line remains connected to the ‘return’ the camera will remain powered. Do not hook this signal up to anything other than ‘dry’

External lighting control
The external lighting control provides a signal that can turn on an external illuminator. When enabled, via the check box on the Camera Settings configuration page this signal will become active when the auto exposure algorithm detects a low light condition. The exposure will be made one second after the signal becomes active.
The signal provides the return path (- side) for a DC power supply. The signal can sink up to 1.5 amperes at 30 volts DC. Exceeding these limits will damage the unit. The
