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 pri nciple 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 def ault registration address).
 The camera is located on the same subnet as the NVR.
 The A ut o Networking feature is enabled o n the camera side.

For details on how to enable this feature on the camera side, see the related document of the
camera.
