Tip: There is a SD card inside of the camera. Remember to initialize it first.
Step：Log in the Web interface of NVR，select Setting>STORAGE>Schedule>Record, enable ANR，modify the resuming time, click Save
When ANR is on, if the network is suddenly disconnected between the NVR and the front-end IPC normally, the NVR can also record a period of video (0-423200s) to the front-end IPC’s SD card storage (that is, the front-end IPC needs to support an SD card, and it can read&write normally after the SD card is installed). After the network restores normally, the video temporarily stored in the SD card can be searched to ensure that the video file will not be lost.
