Temporary security, delivered as a managed service.
Sentryva is built around a straightforward idea: businesses should be able to deploy professional CCTV where they need it, for exactly as long as they need it, without buying permanent infrastructure.
Temporary sites deserve better than a choice between two bad options.
Most temporary sites end up with one of two compromises. A manned guard is expensive, only ever in one place at a time, and stops covering the site the moment they clock off. A cheap camera on a pole looks like security but produces nothing usable if no one's actually watching it — and by the time anyone checks the footage, whatever happened has already happened. Sentryva exists to close that gap: a rapid deployment tower that's live within 48 hours, properly monitored when the site needs it, and collected again the moment the job's done — with no lengthy contract and no infrastructure left behind.
Practical security, not unnecessary complexity.
We focus on commercially useful capabilities: local recording, reliable connectivity, intelligent analytics, flexible hire and a clear support model. The service is designed for construction projects, property operators, industrial sites and other organisations with temporary or changing security requirements.
Footage that actually holds up.
Every REX tower we hire out is built by Upshot UK Ltd, an established UK manufacturer of rapid-deployment security platforms, and REX 700/800 units carry Dahua's 6MP WizSense AI cameras — the same class of hardware used in professional fixed CCTV installations, not consumer kit repurposed for temporary use. We chose that combination deliberately: a tower that's only on site for a few weeks still needs to produce footage a solicitor, insurer or police officer can actually use, not a blurry clip nobody can act on.
Three reasons sites choose Sentryva.
No minimum tie-in
Hire week to week, cancel with a week's notice. Most tower hire runs on a 4–8 week minimum — ours doesn't.
Priced by platform
REX 600's motion sensors and REX 700/800's full CCTV cameras are priced for what they actually carry — not one flat rate regardless of hardware.
Live in 48 hours, off-grid
Solar and battery powered, no mains, no cabling, no groundworks — site survey to live protection in 48 hours.
Focused coverage, not a national call centre.
Sentryva currently operates across Hampshire and the South of England, UK. We've kept the coverage area deliberately focused rather than spreading thin across the whole country from day one — it means a shorter drive to every site, a faster response if something needs attention, and a team that actually knows the patch. If your site falls just outside that area, get in touch anyway — we take enquiries on a case-by-case basis.
