High Voltage DO Device Connection
Even though the camera provides 12V power, this may not be enough for some high voltage DO
devices, such as a ceiling light or a motor that opens or closes a gate. In this case, there is a
need to connect an external relay. See wiring scheme below:
Note that when choosing an appropriate relay, please refer to its specifications and make sure
they match the above design. The triggering circuit voltage has to be around 12V DC and the
switch-controlled circuit voltage has to match the external power supply (e.g. 110V AC or 220V
AC).
The illustration below is a graphic example of connecting a relay to a high voltage DO device.
