Hardware Manual

Other Connections

This section describes the procedures in connecting Digital Input and Output (DI/DO) and

Audio Input and Output devices. The use of these devices, however, is optional.

NOTE: If these connectors will not be used, leave the rubber caps on and the wires twisted

together to ensure cables remain waterproof and eliminate short-circuit hazards.

How to Connect DI/DO Devices (Optional)

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.
