Interfacing to the I/O Connector
The Alarm mode in Image Transfer feature requires the external sensors/devices 
to be connected to the digital input terminal of the I/O Connector. The sensor is 
customer provided and can be a door sensor or infrared red intruder sensor. In 
most applications a simple contact closure is all that is required.

DIRECTLY TO DEVICES THAT REQUIRE LARGE AMOUNTS OF 
CURRENT. IN SOME CASES, A CUSTOM INTERFACE CIRCUIT 
(CUSTOMER PROVIDED) MAY HAVE TO BE USED. SERIOUS DAMAGE 
TO THE NETWORK CAMERA MAY RESULT IF A DEVICE IS 
CONNECTED TO THE I/O CONNECTOR THAT EXCEEDS ITS 
ELECTRICAL CAPABILITY.
