As shown in the table above, voltage decreases as the wire gets longer. Therefore,
the use of an excessively long power cable to the camera may affect the camera’s
performance.
Standard voltage for camera operation : DC 12V±10%.
There may be some deviation in voltage drop depending on the type of wire and the
manufacturer.
Please use a power adaptor that meets the required standards.
Please connect the power after installation.
Please use the input power with just one camera and other devices must not be connected.
