Other Cable Connections (Optional)
This section describes the procedures in preparing and connecting Digital Input and Output
(DI/DO), such as alarms, sensors, etc., and Audio Input and Output devices. The use of these
devices, however, is optional.
NOTE: If these connectors will not be used, leave the caps on to avoid water or dust from
entering the connectors.
How to Connect DI/DO Devices
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.
