Digital Input

Used for connecting external alarm devices and triggering images for specific alarm-based events, the digital input is typically connected to a motion detector (or any other external security device) for taking images on each occasion that the detector is activated.

Digital Output

The supported transistor output can drive a maximum load of 24V DC at 100mA directly, and by connecting additional relay circuitry, can drive even heavier loads.From the Administration Tools you use ON/OFF buttons in the Layout settings to drive the output high or low.
