TION & CONNECTION
Ethernet Connection
Connect the Ethernet cable to the local network or to the Internet.
Power Supply
Use the screwdriver to connect each line (+, –) of the power cable to the corresponding
power port of the camera.


If both PoE (Power over Ethernet) and DC 12V are supplied, the product will operate with the first-
applied power source.
- You can also use a router featuring PoE to supply power to the camera.
- Use PoE that is compliant with the IEEE802.3af protocols.
- It is advisable to use only one power source from PoE and DC12V.

The heater will operate properly only by the power source of PoE. (SNV-7082)
- If using DC 12V, the heater will not operate at all.
- Use PoE in a low-temperature place of less than -10°C.

Be careful not to reverse the polarity when you connect the power cable.

If you want to connect an external device, you must turn off the external device before proceeding.

As shown in the table above, you may encounter a voltage-sag depending on the wire length.
If you use an excessively long wire for camera connection, the camera may not work properly.
- Camera Operating Voltage : DC 12V±10%
- Voltage drop measurements on the chart above may vary depending on the type and manufacture of
the copper cable.
