Computer vision for UK construction sites.
Your CCTV is already on the gate, the compound, the scaffold. It's already recording. Most of the time, nobody's watching. I build vision systems that watch it for you, flagging PPE breaches, logging who's on site, spotting plant movements, and catching hazards before they cause incidents. Built on what you already own. Paid once, yours forever.

What's actually happening on your site right now.
Your H&S manager spot-checks PPE compliance maybe three times a shift. The other twenty-three hours, you're trusting people to do the right thing.
The HSE doesn't accept "we trust people" as a control measure. Site inductions tick a box. So do toolbox talks. But when the inspector turns up, or worse, after an incident, what they want to see is evidence, on every shift, on every gate.
That's what the cameras above your gates can do. They're just not doing it yet.
What I build for construction firms.
PPE compliance monitor
Plugs into your existing CCTV. The system watches your gates and active work zones, identifies workers entering without a hard hat or hi-vis, and sends a flag to a phone, an inbox, or a screen in the site office. Daily summary email lands at 7am with the previous day's compliance rate per gate, ready for your morning meeting. What you get on an HSE visit: a log of every breach, every camera, every shift, going back as far as you want to store it.
Quoted on scope.
Fixed price in writing before any work starts. Hardware, on-site installation, and any opted-in subscriptions quoted separately at cost.
Site entry & headcount
Knows who's on site at any moment, without anyone tapping a card or signing in. Useful for evacuation roll-call, HSE records, and the question subcontractors keep asking: "is my lot still here?" Pairs with your existing CCTV. Counts each person in and out across the gate. Shows you the current site headcount on a phone or a screen in the cabin.

Plant & vehicle tracking
Where's the telehandler. Where's the mixer. When did the skip lorry actually arrive. Time on site per asset, automatically logged from the camera on the gate or the compound. Works on registration plates, vehicle type, or both. Reports drop into an email or a shared sheet weekly. No GPS trackers to fit, no driver compliance to chase.

Slip, trip & spill detection
Flags unattended hazards in walkways, on stairs, in welfare areas. Cables across a route. A spill near the canteen. An object left at the top of a flight of steps. The kind of thing your foreman catches on a walk-round, except now it's caught the moment it appears, by the camera that's already there.

A few of the situations this system handles.
A site with three live gates and subcontractor traffic in and out from 6am. The system watches each gate for PPE compliance, flags breaches as they happen, and sends the site manager a daily summary email at 7am with breach counts per gate and timestamped stills.
A compound storing plant and materials overnight. The system watches the access road and the compound itself, alerts on vehicles or people present outside agreed hours, and logs every legitimate arrival with the registration plate and timestamp.
A site office that needs an accurate live headcount for fire roll-call. The system maintains a running count from the gate cameras, available on a tablet in the cabin and on the site manager's phone. No card-tapping or sign-in book required.
A regional contractor running multiple sites under one H&S team. The system runs at each site, with a single dashboard the H&S lead checks each morning showing compliance rates across the estate and the sites that need attention.
Why this, why me.
It runs on your existing kit.
Most CCTV cameras installed in the last five years are good enough. I'll tell you that for free from a 30-second clip. No replacement hardware unless you genuinely need it.
The code is yours.
Most construction-tech vendors sell a monthly subscription with vendor lock-in. Stop paying, lose access. Mine ships as code in your repo. You can host it yourself, change it, run it on your own hardware, or hand it to your IT team forever.
One person, start to finish.
You email me, you call me, you get the build from me. The person who scopes it is the person who writes it. No account managers, no rotating teams, no handovers.
Faces blurred by default.
GDPR-compliant out of the box. The system identifies behaviour (hard hat on, hi-vis on, person in zone), not individuals. If you need worker identification later, we add it as a deliberate step with the right controls.
Fixed price, in writing, before any work starts.
The quote is the price. The scope is the scope. You decide whether to extend, never me.
A call, then a build.
We talk
Fifteen minutes on a call. You tell me how many sites, what you want flagged, what you've got installed already. Every call ends with a clear answer: a fixed price and timeline in writing, or an honest pointer if it's not the right fit.
I build
Two to six weeks. You get a working system per site, the code in your repo, and the docs your IT team needs to run it.
Every quote breaks out the build fee, hardware, install labour, and any subscriptions in writing before you commit. One total, every line visible.
The things people ask before we start.
Will this work with my existing CCTV?
Almost certainly yes. Most CCTV from the last five years is more than enough for the kind of detection we're doing. The handful of times it isn't, it's because of a bad camera angle or a very wide lens, both of which we work out at the scoping stage before any money changes hands.
Where does the footage live?
On your own hardware, on your site, by default. The system sits next to your existing CCTV recorder and processes the feed locally. Nothing leaves the site unless you specifically choose a cloud setup, which most clients don't. This keeps your data protection officer happy and your IT team in control.
What about workers in the system?
Faces are blurred the moment the system processes the footage, before any alert, clip, or log is created. Your existing CCTV records the same way it always has, governed by whatever data protection setup you already have in place. The new system only ever works with the blurred version from that point on. Worker identification is a separate piece of work with its own consent and governance, only added if you genuinely need it.
What about subcontractors?
The system flags PPE breaches at the gate regardless of who employs the person. Your own staff, subcontractors, agency workers, visitors all treated the same way. The breach log is yours to share with whoever needs it, which most clients do with their subs as part of normal site management.
Will it work in bad weather, low light, on a busy gate?
Modern CCTV handles dawn, dusk, and most weather without issue. Night work needs an infrared-capable camera, which most newer CCTV already has. Heavy rain and direct low sun can briefly reduce accuracy, but the system logs uncertain detections rather than missing them, so you still have a record. We confirm what's realistic for your specific site during scoping.
How quickly can it be running on my site?
Two to four weeks for a single site. Multi-site rollouts are quicker per site after the first one because we reuse the configuration. A three-site rollout typically runs four to six weeks. Larger estates of twenty sites and up usually run eight to twelve weeks once the standard is agreed, with a phased rollout for anything bigger.
What happens if I want to add a feature later?
You own the system, so you have three options. Extend it yourself if you have the in-house skill. Hand it to your IT team. Or come back to me for another fixed-price job. No subscription gating new features and no per-camera fees creeping in over time.
Tell me what you need built.
