Samsung SNB-5001 Alarm input Wiring Diagram, Electrical Resistance of Copper Wire at 20C 68F

Be careful not to reverse the polarity when you connect the power cable.

-Please connect the power adapter when the installation is completed.

-As shown in the table below, 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.
