Connection design
Transistor (Open Collector)
Voltage & Current
< 24V DC, < 50mA
After mapping the wires to the terminal block, connect the terminal block to the DIO connector
of the camera and make sure to wrap the connection using a waterproof tape (can be
purchased in hardware stores).
Typical Connection
Based on these specifications, if the DI device has a voltage of 0V ~ 30V or the DO device has
a voltage of < 24V (< 50mA), then the camera can supply internal power to these devices and
there is no need to connect the DI/DO device to an external power source.
In this case, use the
GND
and
DI
pins to connect a DI device and use the
12V
and
DO
pins to
connect a DO device. See wiring scheme below:
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:
