Prepare the DI/DO Connector (Optional)

Depending on your surveillance needs, you may connect digital input or output devices to your

camera to trigger events or notifications.

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.

You can connect one DI and one DO device to your camera.

To connect an input (DI) or an output device (DO), map the wires to the pin combinations below:
