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.
Size O.D. between 4.6 mm (0.181 in.) and 7.9 mm (0.312 in.)

Central Conductor Standard copper center
Terminal Connector Male BNC

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.
Alarm Connections
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.
Wire alarms either Normally Open (N.O.) or Normally Closed (N.C.); you must program the
alarm inputs N.O. (the default) or N.C. through the on-screen display menus.
The following table summarizes the maximum distances for alarm wires:
