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.
