Some DirectIP cameras have built-in alarm in/out port. Normally, alarm input has TTL voltage level and NC/NO programmable. Alarm output only supports the NO mode with relay output. With reference to the alarm in/out specification, you can connect your alarm devices such as smoke sensor or fire alarm to the alarm in/out port on DirectIP camera.

DirectIP NVRs can set and use the each DirectIP camera’s alarm in/out ports as well as NVR’s alarm in/out ports.

For using alarm input device connected in DirectIP, you should select [Setup]-[Event]-[Alarm-In] menu sequentially. Then you can select the alarm input device connected in DirectIP as event signal channel.

For using alarm output device connected in DirectIP, you should select [Setup]-[Device]-[Alarm-Out] menu sequentially, Then you can select the alarm output device connected in DirectIP as alarm output channel.

Using the above setup configuration, you can use external alarm devices directly wired to the Camera input which will be seen by the system as if it were connected to the NVR directly.
