b Connect an external device to the EXT connector.
Remove 9 mm - 10 mm of the outer jacket of the cable from the
external device and twist the core of the cable to prevent a short cir-
cuit.
Specification of cord (wire): AWG #22 - #28 single core, twisted
* Make sure that the exposed core wires are completely hidden
after inserting the cable.
Important:
• Do not connect 2 wires or more directly to a termi-
nal. When it is necessary to connect 2 wires or
more, use a splitter.
• Connect an external device with verifying that the
ratings are within the specification below.

q GND
w AUX OUT
Output specification: Open collector output (Maximum applied voltage: 20 V DC)
Open: 4 - 5 V DC by internal pull-up
Close: Output voltage of 1 V DC or less (50 mA or less)
e ALARM OUT
Same as AUX OUT
r ALARM IN
Input specification: Non-voltage make contact (4 - 5 V DC internal pull-up)
OFF: Open or 4 - 5 V DC
ON: Make contact with GND (drive current: 1 mA or more)
• When using PoE (Power over Ethernet: IEEE802.3af compliant)
Connect a LAN cable (category 5 or better) between a PoE device (such as a PoE hub) and
the network connector of the camera.
Important:
• Use all of 4 pairs (8 pins) of the LAN cable.
• Maximum length of an Ethernet cable that can be connected is 100 m.
• Make sure that the PoE device in use is compliant with IEEE802.3af standard.
• When connecting both the 12 V DC power supply and the PoE device for power supply,
PoE will be used for power supply.
• When disconnecting the LAN cable once, connect the cable again after 2 seconds or
more from the disconnection. When the cable is connected before 2 seconds passed, the
power may not be supplied from the PoE device.
• Refer to the provided slip (Recommended network devices for PoE (IEEE802.3af compli-
ant) connection with the WV-NP304) for applicable PoE devices.
v Connect a LAN cable (category 5 or better)
to the network connector on the rear.
