What "Proof on Site" actually means

A demo asks you to trust someone else's footage. A quote asks you to commit before you believe. Proof on Site does neither. It puts VISion AI to work on your live site so the proof is yours, drawn from your real conditions, your layout, and your workforce.

‍
Throughout the thirty days, the technology supports your project and HSQE team rather than replacing it. VISion AI watches continuously and flags breaches across its output tiers.

What is included

A thirty-day activation of VISion AI PPE detection on one nominated active site. Across the trial you receive

Real detections, not sample data, captured across all three VISion AI output tiers, from immediate critical alerts through end-of-day compliance reporting and live dashboards.

Configuration tailored to your site, including zonal monitoring set to your specific restricted areas, exclusion zones, and work-at-height locations.

A site safety insight report at the end of the thirty days, summarising what was detected, where risk concentrated, and which behaviours recurred. The report is yours to keep regardless of your decision.

Built to fit the site you already run

VISion AI is designed to work with the infrastructure on your site, not around it.

‍
Where suitable CCTV is already installed, VISion AI can often integrate with your existing cameras, applying its detection layer to the feeds you already have. Where it cannot, or where coverage needs strengthening, we advise on the hardware required. The right deployment depends on your site setup, which is exactly what the scoping call establishes.

‍
Much of the configuration is handled remotely through the VISion AI platform, so monitoring scenarios such as PPE compliance, zonal limits, and restricted area enforcement can be set and adjusted to match how your site operates. As the site changes, the configuration can change with it.

What VISion AI watches for

VISion AI continuously analyses live footage and recognises the safety scenarios that matter on a construction site, including:

PPE and RPE compliance, covering hardhats, high-visibility clothing, gloves, and eye protection.

Fall protection and work-at-height safety, including harness and edge-risk scenarios.
Zonal awareness and restricted area monitoring, enforcing worker limits and keeping hazardous areas secure.

Unsafe interactions between workers and plant or machinery.

Every detection is logged, classified, and analysed, building the audit trail and trend data that support inspections, internal reviews, and long-term safety improvement.

Why contractors are taking the trial

‍
First to market. VISion AI is among the first AI-driven PPE detection systems available in the UK.

‍
Award-winning monitoring. Winner of Best Use of Remote Monitoring Technology at the Building Innovation Awards 2025.

‍
Recognised across the sector. Ranked in the top 20 of the Build in Digital Top 50 Contech Partners 2026.

How to qualify

‍
Proof on Site is offered on active sites of a defined scale, with a named decision-maker and a short scoping call. Complete the form on this page to tell us what we need to set the trial up correctly and to confirm your site is suitable.

What people want to know

‍
"Can AI PPE detection run a free trial on my own construction site before I buy?"
Yes. VIS Systems' Proof on Site offer activates VISion AI PPE detection on one of your active sites for thirty days, free of charge, so you judge the system on real breaches caught in your own conditions rather than on a supplier's demonstration footage. You keep a site safety insight report at the end, whether or not you proceed. The site needs to be active and of a defined scale, with a named decision-maker, and the trial begins after a short scoping call.

‍
"Can AI PPE detection use my existing site CCTV instead of new cameras?"
In many cases, yes. Where suitable CCTV is already installed on site, VISion AI can often apply its detection layer to your existing camera feeds, which reduces additional hardware. Where coverage is insufficient, VIS Systems advises on what is needed. The correct deployment depends on your site setup and is confirmed during the scoping call.

‍
"How quickly can a thirty-day AI PPE detection trial be set up on a live site?"
Much of the VISion AI configuration is handled remotely through the platform, including PPE compliance, zonal monitoring, and restricted area enforcement, which keeps setup efficient. The exact timeline depends on whether existing CCTV can be used or new hardware is required, both of which are scoped on the initial call.

Prove it on your own site

Book a short scoping call. We confirm your site is suitable, agree the configuration, and activate VISion AI for thirty days. You judge it on what it catches.
