As shown in the table above, voltage decreases as the wire gets longer. Therefore use of an excessively
long adaptor output line for connection to the camera may affect the performance of the camera.
*
Standard voltage for camera operation
：
SCD-1020P/1040P: DC 12V ±10%, AC 24V ± 10%
SCD-1020PD/1040PD: DC 12V ±10%
*
There may be some deviation in voltage drop depending on the type of wire and the manufacturer.
`
Be sure to connect power only after all the installation is complete.
`
Note that AC / DC adaptor is not supplied with camera.
