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.
