Backup/NM Standby Setup

Note :

1. All NVRs must be the same model and upgraded with the same firmware.

2. All NVRs must be in the same IP segment.

3. When Master NVR fail down and the Slave NVR will take over the task of it and then keep recording, but both of them will lose 90~120s recordings cos the Slave NVR need time to judge if the Master NVR is really offline. Meanwhile, you cannot do playback from any one of them.

4. But when you manually past the task and recordings from Slave NVR to the Master NVR when Master NVR recovered, the Master NVR will start to record and you can do playback from it.

N+M Hot Standby

N+M basic concept

• N = The number of NVR master

• M = The number of NVR slave

• When master cash, one slave take over master and start work

• When master get back, user can turn slave into standby position manually, user can choose to past back record data in slave at same time

• N+M can realize NVR secure backup and monitoring system uninterrupted work.

Real IP

• Real IP = master and slave NVR local IP

• Cluster IP = virtual IP, only on web of Master NVR, user can set this Cluster IP (Note : must be In the same network segment with master and slave and not occupied.)

• Each Master NVR have a different Cluster IP. If you want to use a software (VMS) to manage the N+M system, you can add the Cluster IP of N pcs Master devices to preview and playback. When one Master NVR crashed, the software will access the Slave NVR to get the realtime preview and playback automatically. But you may failed at the transition about 90s to 120s because the Master NVR is transfer the task from Master to Slave NVR

Cluster IP demo（5+2 mode

1. normal mode In normal mode, slave stay in standby position

2. When one master NVR cashes When one master cashes, one slave takes over master’s job

3. When two masters NVR cash Master N1 cashes，master N4 cashes at the same time， slave NVRs take over two masters’job

4. when three masters NVR cash master N1，master N4 cash ,slave M1，M2 take over .If N5 cash now, no slave can take over N5.

5.When master NVR get back Master N1 cash ，M1 take over，master N1 get back， user can choose to turn M1 into standby position，and get N1 back to work , user must load cluster IP or slave NVR’s IP to complete this process

How to Configure the N+M

Step 1. Set the cluster IP in the web of Master NVR.

Step 2. Add the Slave NVR on the web of it.

Step 3. Add the Master NVR on the web of Slave NVR.

Step 4. Set a “Arbitrage IP” on the web of Slave NVR.

Step 5. Enable Cluster Control on the web of Slave NVR.

Step 6. Cluster Control enabled on the web of Slave NVR.

Step 7. Check the status of Master NVR on the web of Slave NVR, now “Working”

Step 8. Check the status of Slave NVR on the web of it, now “Free”.

Step 9. If the Master NVR disconnected, the status of Master NVR is “Abnormity”.

Step 10. After about 120s, the Slave NVR take over the task of Master slave and the status is “Using” now.

Step 11. If the Master NVR online again, the status “Backup” and click the tick.

Step 12. Then Master NVR will take over the task again.

Step 13. Transfer the recording data to the Master NVR on the Slave NVR web manually.
