DI/DO Input specifications

DO Digital Output:

￿Normal: open circuit

￿Trigger: short circuit

After powering on or rebooting the DCS-2121, the camera will be in Normal mode by default.

DI Digital Input:

￿Normal: no current

￿Trigger: 12V current

As the Digital Input signal is controlled by an external device, we recommend that you set your device to feed no current normally, and feed a 12V current only to trigger a DI event on the DCS-2121.
