1 About the NVR1822 and NVR1825

1.1 Product Introduct ion

Kedacom NVR1822/NVR1825 (hereinafter referred to as the NVR) is a turnkey solution for video surveillance and video recor ding. The NVR supports Open Netw ork 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 capabi lities m ake the NVR easy to use with functions like Automaticall y Adding Devices and One-Click Partition and Initialization and meet various customer needs with functions like Image Flip and Privacy M ask for every day security users t o advanced video surveillance users.

The NVR works with the following management system and applications:

 NVR Station: is a complete system for device manage ment, video su rveillanc e, and v ideo recor ding.  NVR Station Web: is a web-based application of the NVR Station.  Mobile NVR Client: is an iOS/ Andriod-compatible mobile application of the NVR Station.

For details about the NVR appearance and sp ecifications, see chapter 8 "Specifications."

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 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 defau lt r egistr at ion address).  The camera is located on the same subnet as the NVR.  The Aut o N etworking feature is enabled on t he camera side.

For details on how to enable this feature on the camera side, see t he r elated document of the

camera. Alternatively, this feature can add the camera to the NVR when t he following conditions are true:  The registration address of the camera is one IP address of the NVR. (This indicates that the

camera has registered wit h t he N VR.)  The camera can reach the NV R. This feature can also retriev e a camera t hat register ed with t he NVR but was p ree mpted by anoth er NVR

later if the following conditions are true:
