This section describes the procedures in preparing the Digital Input and Output (DI/DO) and
Audio Input and Output devices that you can connect to the camera using the bundled terminal
blocks. The use of these devices, however, is optional.
Connecting DI/DO and Audio Devices (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
insi
de 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.
