Prepare the DI/DO and Audio Input / Output Connector 
(Optional) 
Depending on your surveillance needs, you may connect digital input / output or audio input / 
output devices to your camera. The camera comes with one (1) terminal block for both digital and 
audio input / output devices. 
How to Connect DI/DO Devices 
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. 
Press and hold the orange tab as you insert the wire through the pin slot, then release the orange 
tab to secure the wire. 
To connect digital input / output devices (DI/DO), map the pins to one of the pin combinations
