ALARM IN connections
Connect external sensors to the 8-pin haness connec-
tor. Each alarm sensor should be connected with G
(GND). Input specifications are low-active, non-volt-
age contact (ON when active) or open collector (Low
when active).
Cautions
Alarm input connection must be connected to only
one port of two communication ports.
Do not connect one alarm sensor to the several
camera’s alarm input connector.
