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. 
 
Wireless trigger and receiver devices are available which eliminate the need for cabling 
between the door switch or motion detector and the Observer Camera (see Appendix I). 
 
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 can be re-triggered.  Do not hook this 
signal up to anything other than ‘dry’ (un-powered) switch contacts. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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.
