6.2 Video Connection
Coaxial cable terminated with a male BNC connector is the
most common method for transmitting composite video from
the camera to a monitor. If the head end device features built in
video termination then no termination connector is needed.
Table 6.3 Recommended Coax Specifications
Connecting the Video
To connect the video, do the following:
1. Terminate the coaxial cable from the head end system with
a male BNC connector. Alternately, switch the head end
system to 75 Ohm termination.
2. Connect the male BNC connector to the Video Out female
BNC connector from the base of the camera.

The camera provides four alarm inputs and one alarm output.
Each input can be activated by dry contact devices such as
pressure pads, passive infrared detectors, door contacts, and
similar devices. The alarm output can activate an external
device, such as a buzzer.
