Kedacom NVR1821/2800 series NVR (hereinafter referred to as the NVR) is a turnkey solution for video
surveillance and video recording. The NVR supports Open Network Video Interface Forum (ONVIF) and
Real Time Streaming Protocol (RTSP) interoperability standards. Additionally, it features native
integration to cameras and encoders from third party manufacturers, therefore making it an open
system.
The advanced system capabilities make the NVR easy to use with functions like Automatically Adding
Devices and One-Click Partition and Initialization and meet various customer needs with functions like
Record Fragment and Privacy Mask for every day security users to advanced video surveillance users.
The NVR works with the following management system and applications:

3 Monitoring a Site
3.1 Automatically Adding the Target Camera
You can use the Automatically Adding Devices feature to add the target camera that is monitoring the
target site to your NVR.
Working principle of the feature
This feature automatically adds a camera to an NVR when the following conditions are true:
The registration address of the camera is 224.1.1.1 (the default registration address).
The camera is located on the same subnet as the NVR.
The Auto Networking feature is enabled on the camera side.
For details on how to enable this feature on the camera side, see the related document of the
camera.
Alternatively, this feature can add the camera to the NVR when the following conditions are true:
The registration address of the camera is one IP address of the NVR.
The camera can reach the NVR.
This feature can also retrieve a camera that registered with the NVR but was preempted by another NVR
later if the following conditions are true:
The camera is still on the camera list of the NVR.
The camera is located on the same subnet as the NVR.
After the target camera is added to your NVR, you can find the camera on the camera list. Then, drag
the target camera to a view window on the main screen of your NVR to monitor the target site.
Note
The registration address of a camera is one IP address of the NVR to which the camera registers.
Querying the registration address of a camera
You can use IPCSearch to query the registration address of a camera. The following is an example.
