Perimeter-to-Site Security That Deters, Detects and Responds

Construction sites contain valuable materials, equipment and machinery and are often targeted outside working hours. BauWatch provides active site safety and security designed to deter, detect and respond to incidents, helping prevent loss, damage and disruption, day and night.

Highly Visible Security Towers, Deter Before Incidents Happen

Our tall, clearly visible security systems are designed to discourage theft and unauthorised access before an incident occurs, not just record it after the fact.

Full Visibility & Incident Reporting

Access live footage and recordings via the MyBauWatch platform, with clear incident reports provided to support site management, insurance and accountability.

24/7 Alarm Monitoring by Our NSI Gold Alarm Centre

'Our towers integrate intruder detection, live audio challenge and alarm monitoring, stopping incidents at the perimeter before they escalate. All sites are monitored from our NSI Gold alarm receiving centre, 24 hours a day.

Solar, Wired & 4G, No Mains Power or Internet Needed

Our security towers run on solar, wired, or 4G-connected power — no mains supply or internet connection required. Ideal for temporary construction sites, remote plots, and live building projects where infrastructure is still being installed.

Get in Touch

The team did a great job and stopped the break-in escalating. We were alerted straight away and BauWatch had the police on site in no time at all and the intruders were arrested.

Our mobile towers use intelligent video analytics to detect people and vehicles within agreed time windows. Alerts are sent to our 24/7, NSI Gold alarm receiving centre for remote alarm monitoring, where trained specialists verify events in real time and take immediate action (audio challenge, notify police or your nominated security partner).

We provide on-site installation within 48 hours. A free site check maps perimeter, entrances and blind spots; we then recommend the right number and placement. Towers work with or without mains (solar options available).

Wired towers include an integrated battery backup that keeps the system running for up to 48 hours during power loss. We also offer autonomous solar-powered systems (solar + battery + generator) for sites without mains power, with secure 4G connectivity for uninterrupted remote monitoring. Automated daily remote checks and our service platform identify issues fast; many are fixed remotely, and our technicians handle on-site repairs where needed.

Typically not. Guarding costs—especially with night surcharges—often exceed the cost of our 24/7 monitored solution. Human-only patrols are also more prone to gaps and error. BauWatch provides continuous, verified monitoring with immediate audio challenge and escalation, delivering stronger prevention and better value per protected hour.

Yes. For construction site deployments, we mask or avoid public space, use clear signage and follow GDPR requirements. Footage is retained for 28 days, access is role-based, and we don’t store biometric identifiers (e.g., faces or number plates) beyond incident evidence.
