Connecting Digital Input / Output Devices (Optional)
Depending on your surveillance needs, you may connect digital input / output devices to your
camera using the supplied terminal block.
Digital Input (DI) devices can be used to notify the camera about an activity in the camera site. DI
can be triggers of events. For example, you can connect a “panic button” to the camera; as such
when the panic button is pressed, the alarm signal will be sent through the camera. Other
common DI device applications are emergency button, smoke detector, passive infrared sensor,
etc.
Digital Output (DO) devices are external devices that are activated by the camera upon an event
inside the camera. For example, you can connect an “alarm horn” to the camera; as such when
an event occurs inside the camera (e.g. detected intruder), the alarm horn will sound. Other
common DO device applications are motion-triggered lights, electric fence, magnetic door locks,
etc.
To connect digital input / output devices (DI/DO), map the pins to one of the pin combinations
below:

Loosen the screw and insert the wire through the pin slot on the terminal block, then tighten the
screw to secure the wire. Connect the terminal block to the cable connector of the camera.
After mapping the wires, connect the terminal block to the connector on the camera and make
sure to wrap the cable connection using a waterproof tape.
