VMS / NVR Server
Enter the number of cameras, bitrate and retention and I compute the recording bandwidth, storage (TB), write IOPS, server RAM and how many servers you need by their throughput/channel limit.
Bandwidth
0 Mbps
recording all cameras
Storage
0 TB
for the chosen retention
Write IOPS
0
sequential write (low)
Server RAM
0 GB
base + per camera
Servers
0
by throughput/channel limit
Cameras / server
0
even split
Why that many servers?

Storage uses decimal TB (1 TB = 10¹² bytes): BW(Mbps)/8 = MB/s, × 86400 s/day × days ÷ 10⁶. Add headroom for the operating system, indexes, RAID and growth. IOPS are low because recording is large-file sequential writing (≈ one stream per camera).
