The recommended adaptor specification
for SIR-4260 is DC 12V/4A.
Please check the standard power
requirement before connecting to power.
• 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 : DC 12V±10%, AC 24V±10%
※……
There may be some deviation in voltage drop depending on the type of wire and the
manufacturer.
When the resistance value of copper wire is at [20°C(68°F)]
