The size of the recording is mainly determined by its bit rate. The higher the bit rate, the better image and audio quality, and the bigger the file size. Vice versa.

Applies to: Reolink NVRs

The table below shows how long the Reolink NVR can record 24/7 under different Bit-Rate (bitrate of clear stream+bitrate of fluent stream) and HDD capacities. The results are calculated as follows:

Note: Compared with 24/7 recording, the maximum video length of motion detection recording will be much longer.

Note: Unlike the 2-TB HDD that comes with the Reolink NVRs with less than (or equal to) 8 channels, the HDD coming with the Reolink 16-Channels NVR is 3 TB. The capacity of Reolink NVRs can be expanded to up to 12 TB. You can refer to How to Expand the Capacity of Reolink NVRs for more details.
