● INSTALLATION & 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.
