Recording that never blinks

Video surveillance punishes storage that wasn't designed for it — hundreds of continuous write streams, 24/7 duty cycles, and zero tolerance for lost footage. The Vess line was purpose-built for exactly this, from compact 4-bay NVRs to petabyte-scale analytics engines.

Surveillance

Appliances sized to the site

One product family covers the range: Vess A3120 for a storefront's worth of cameras, A3340 for mainstream commercial sites, and A6000/A7000 appliances where camera counts climb into the hundreds. Each runs the VMS directly — recording server and storage in a single chassis.

Surveillance

AI where the cameras are

The Vess A8000 family adds the compute that modern analytics demand. GPU-capable configurations run detection and classification on-box, so bandwidth-heavy raw streams don't have to leave the site to become searchable events.

Scale storage independently

When retention requirements grow faster than camera counts, Vess R3000 RAID with J3000 expansion shelves decouples storage from recording — add capacity behind the appliances without re-architecting the deployment.

FAQ

Surveillance questions, answered

How do I size an NVR for my camera plan?+

Camera count, resolution, frame rate, codec, and retention days drive the math. Send us those five numbers in a quote request and we'll return a specific Vess model and drive configuration with headroom for growth.

Do Vess appliances work with our VMS?+

The Vess A-series is validated with the major video management platforms — Milestone, Genetec, Network Optix, and others. Tell us which VMS and version you run and we'll confirm the right configuration.

What happens to footage if a drive fails?+

Vess appliances use hardware RAID, so a failed drive degrades the array without stopping recording. Swap the drive and the array rebuilds in the background. For critical sites we recommend keeping a qualified spare module on the shelf — we can add one to any quote.
