Connecting DI/DO Devices (Optional)
Depending on your surveillance needs, you may connect one (1) digital input and one (1) digital
output device to the main unit 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 e
xample, 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.
1. Loosen the screws on the terminal block.
2. Connect the input/output pins to the corresponding pins on the terminal block, see mapping
table below.
3. Tighten the screws on the terminal block when done.
