Alarm Input

–AWG 26-16 max.(0.13-1.5 mm2); cut back 5 mm (0.2 in) of insulation.

–Impedence: Internal pull-up 10 kOhm to +5 VDC.

–Input voltage range: -5 VDC minimum to 40 VDC maximum.

–Input voltage treshold: low voltage 0.8 V maximum, high voltage 2.4 V minimum.

–Configurable as active low or active high.

Use the alarm input to connect external alarm devices such as door contacts or sensors. A zero potential make or break contact can be used as the actuator (use a bounce-free contact system).

Relay output

–Max. wire diameter AWG 22-28 for both stranded and solid; cut back 5 mm (0.2 in) of insulation.

–Output relay switching capability: Max voltage 30VAC or +40 VDC. Max 0.5 A continuous, 10 VA.

–Max. 42 V allowed between camera ground and each of the relay pins.
