Surveillance Storage Sizing

How much storage do your cameras actually need?

Enter your camera count, resolution, and retention. You'll get the capacity to plan for and a TrueNAS configuration sized to match — in under a minute.

Your deployment

Across all sites you want on one platform.
Estimated bitrate
4.0Mbps / camera
Continuous recording. Smart-codec or motion-only recording uses less.
Most security teams treat all footage as critical. Recommends a dual-controller HA design — police, hospital, casino, evidence, compliance.

Capacity = cameras × bitrate (Mbps) × 86,400 × days ÷ 8 ÷ 1,000,000, plus 30% growth headroom. Bitrate is estimated from resolution, codec, and frame rate. A standard surveillance sizing model — your VMS overhead, scene complexity, and recording mode will shift the real number. High availability (dual-controller) is available on H, M, F, and V-Series; the R-Series is single-controller. 10GbE is the practical minimum network interface, even when aggregate ingest calculates lower.
Why teams record on TrueNAS

Built for the way surveillance actually scales.

Never drop a frame

OpenZFS is sequential-write optimized, so it keeps up with thousands of 4K streams at once. Every camera, every site, recorded clean.

Footage that holds up as evidence

OpenZFS scrubbing and self-healing catch bit-rot before it corrupts a file. What you recorded is what you play back, months later.

Ransomware-resilient by design

Immutable snapshots and replication live in the storage layer. No separate product to buy, no extra license to recover a clean copy.

Grow without re-architecting

Start at 20TB and scale to 40+PB on one platform. Add cameras and drives without per-camera fees or a forklift upgrade.

Want these numbers checked against your actual sites?

A storage specialist can validate your sizing, map it to your VMS — Milestone, Genetec, Avigilon, and others — and put a real cost-and-refresh comparison next to what you run today. No obligation.
