Applies to: Reolink NVRs
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.
The table below shows how long the Reolink NVR can record for 24/7 under different Bit-Rate (bitrate of clear stream+bitrate of fluent stream) and HDD capacity. The results are calculated as follows:
Note: Compared with 24/7 recording, the maximum video length of motion detection recording will be much longer.
|Bit-Rate/kbps||Total Recordings Channels||Maximum Video Length for 2 TB HDD/days||Maximum Video Length for 3 TB HDD/days||Maximum Video Length for 4 TB HDD/days||Maximum Video Length for 8 TB HDD/days||Maximum Video Length for 12 TB HDD/days|
Note: Unlike the 2-TB HDD that comes with the Reolink NVRs with less than (or equal to) 8 channels, the HDD capacity of a Reolink 16-Channels NVR is 3 TB, which can later be replaced with a 4-TB one. The capacity of Reolink NVRs can be expanded to up to 12 TB. You may refer to How to Expand the Capacity of Reolink NVRs for more details.
