How to Connect DI/DO Devices (Optional)
Depending on your surveillance needs, you may connect one digital input and one digital output
device to your camera.
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.
Loosen the screw and insert the wire through the pin slot, then tighten the screw to secure the
wire.
To connect digital input / output devices (DI/DO), map the pins to one of the pin combinations
below:
