When the HDD/SD card is full, the NVR/camera will stop recording. If you want to make the NVR/camera overwrite the old files automatically, refer to the below guides.
Applies to: All Reolink cameras and NVRs except Argus 2, Argus Eco, Argus Pro, Argus PT, Argus 2E, Reolink GO, Reolink GO PT, and add-on cameras like B400, B800, D400, D800, B500, D500, B1200, D1200
Step 1. Log in to your Reolink Device on Reolink Client and click the Device Settings button.
Step 2. Go to the Surveillance > Record page. Enable Overwrite to set the HDD/SD card to overwrite.
Note: NVRs with Hw No. H3MB18/N2MB02/N3MB01/N5MB01/N6MB01/N7MB01 have the overwrite interval option. You can configure the NVR to overwrite the old recordings at a certain interval.
