Power-in Connections
Notes:
• Use only a class-2 power supply suitable to the
voltage and current required by the camera. See
specifications.
• Use a UL listed cable (VW-1, style 1007) to pre-
vent fire or electric shock.
You can use the formula below to select the power
supply, and power cable. The supplied voltage to the
power-in terminals must be between 10.8V and 16V.

1. Connect the power cable to the terminals while
identifying the polarity.
2. Fasten the screws.

Notes:
• See specifications for each terminal.
• Use a relay when the connected device exceeds
the ratings in voltage or current.
• The optical sensor validates the Day/Night function
if B/W is set to EXT in the setup menu.
Network Connections
Network Connection Types
• Use a router or switching hub when multiple cam-
eras are connected.
• Use a router handling PPPoE (PPP over Ethernet)
when running PPPoE to connect with the Internet,
because the camera is incapable of it.
• Use network cables complying with category5.
• Direct Connection to PC (Type 1)
