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.
Many DirectIP cameras have spot output and see the NTSC/PAL D1 resolution image to be able to see the image during installation. But, some cameras do not support spot output. So, you should check whether your cameras support spot output or not. Spot output ports are broken into two types - RCA and terminal block. If you want to use spot output, you should check spot output port type of your camera. Spot output on DC-X1XXX series camera works until the camera is registered to a DirectIP NVR.
