1.
Power In:
Connects to DC 12V/AC 24V (NCR875E/NCR875PRO) or DC 24V/AC 24V (NCR875EH/
NCR875PROH) power supply. If using the DC power supply, make sure the power connector is wired to
correct polarities (Red+/Black–). If you are to use power via the PoE connection, this connector is not used.
2.
RJ-45 (Ethernet/PoE):
Connects to the LAN port of a standard 10BaseT/100BaseTX network device,
e.g. hub, switch or router. If you want to supply the camera with power via a PoE coonnection, you are
supposed to use an IEEE 802.3af compliant network device.
3.
BNC:
Connects to composite video in connector of a monitor.
4.
Audio Out:
Connects to an external speaker.
5.
Audio In:
Connects to an external microphone.
6.
Alarm Out:
Connects to alarm device that responds to alarm signals, such as buzzers or LED lights.
Besides, an external relay is also employed as a switch accompanying the buzzer or LED light. Therefore,
a diode is recommended being connected in parallel with the relay to protect against transient voltages.
Note that the supplied voltage and current for the relay must not exceed DC 30V and 1A.
