Samsung SNV-7082, SND-7082F, SNB-7002 user manual Ethernet Connection, Power Supply

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.

J 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.

Electrical Resistance of Copper Wire at [20°C (68°F)]

Copper Wire Gauge (AWG)	#24(0.22mm2)	#22(0.33mm2)	#20(0.52mm2)	#18(0.83mm2)
Resistance (Ω/m)	0.078	0.050	0.030	0.018
Drop Voltage (V/m)	0.028	0.018	0.011	0.006
Recommended Distance (m)	Less than 20	Less than 30	Less than 30	Less than 30

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.
