    Who is this for?

    For construction companies, housing developers, civil engineering firms, and site managers who need proven security on active building sites — especially those with no mains electricity, changing site layouts, and high-value plant and materials.

    • Housing developers with new-build estates and multi-phase projects
    • Commercial construction projects and office fit-outs
    • Civil engineering and infrastructure works including highways and rail
    • Demolition and site clearance contractors
    • Temporary plant yards, material storage compounds, and welfare areas
    • Local authority and public sector capital projects
    • Solar farm and renewable energy construction sites

    Construction site security problems we solve

    • Tools, materials, and plant stolen overnight or at weekends — costing thousands per incident and causing project delays that compound into penalty clauses
    • No mains power available on site, ruling out traditional wired CCTV and alarm systems
    • Unauthorised access by trespassers, rough sleepers, or children putting people at risk and creating liability exposure
    • Your insurer mandates monitored security with NSI Gold certification but your current setup does not meet the specification
    • Vandalism and arson targeting unoccupied sites — particularly over bank holidays and Christmas shutdowns
    • Your site layout changes every few weeks as the build progresses, making fixed camera positions impractical

    What is included in our construction site security service

    Solar-Powered Rapid-Deploy CCTV Towers

    Self-contained mobile towers with integrated solar panels, battery banks, and 4G connectivity. Each tower provides 360-degree coverage with no mains power, no broadband, and no trenching required. Deployed in under 2 hours per unit.

    PTZ Cameras with Smart Tracking

    Pan-tilt-zoom cameras that automatically detect and track intruders across the site. When motion is detected, the PTZ locks on and follows the target while recording in full HD — giving the monitoring centre clear footage to act on.

    Solar Power & Battery Backup

    High-efficiency solar panels paired with deep-cycle lithium batteries keep the system running 24/7 — even through overcast winter weeks. Battery capacity is sized for a minimum of 5 days without sunlight, with remote battery monitoring as standard.

    Wireless Perimeter Intruder Detection

    PIR beam detectors and fence-mounted sensors create a wireless detection perimeter around your site boundary. When triggered, the PTZ camera automatically points to the breach zone and the monitoring centre receives an immediate alert.

    24/7 NSI Gold Remote Monitoring

    Every alarm activation is received by our NSI Gold-approved monitoring centre in real time. Operators verify the threat via live PTZ cameras, issue an audio challenge through on-site speakers, and dispatch mobile response or police if the intruder does not leave.

    Mobile Response Teams

    When an intrusion is confirmed, a mobile response unit is dispatched to your site — typically arriving within 15 to 20 minutes in the Luton, Bedford, and Hertfordshire area.

    Scope of works

    Our qualified engineers carry out the following as standard:

    Initial site survey, risk assessment, and perimeter vulnerability mapping
    CCTV tower positioning for maximum coverage of high-value zones and access points
    Solar panel orientation and battery sizing based on site location and season
    PTZ camera configuration with smart tracking zones and preset patrol routes
    Wireless PIR beam and fence sensor deployment along the site perimeter
    4G connectivity setup and monitoring centre integration
    Audio challenge speaker installation and configuration
    Full system testing, commissioning, and false alarm tuning
    Site manager handover with app access and training
    Ongoing tower relocation as build phases progress — included in the service

    Case Study

    Solar-powered site security for a 14-month new-build housing development with no mains power

    Housing Developer — Houghton Regis, Bedfordshire

    Scale4 CCTV towers and perimeter detection covering an 8-acre site
    Duration14 months (ongoing hire)
    Outcome4 solar-powered CCTV towers deployed
    Challenge: A regional housing developer had experienced two significant plant thefts totalling over 40,000 pounds from an 8-acre new-build site near Houghton Regis. The site had no mains power, no broadband, and the layout was changing every 4 to 6 weeks as new plots were started. Their insurer required NSI Gold-monitored security as a condition of continued cover.
    Solution: We deployed 4 solar-powered CCTV towers with PTZ smart tracking cameras, positioned to cover the main compound, two material storage areas, and the site entrance. Wireless PIR beams were installed along the perimeter fencing. The entire system was connected to 24/7 NSI Gold monitoring with audio challenge and mobile response. We relocated towers 6 times during the 14-month project as the build progressed.

    Frequently asked questions

    Do your systems work without mains power on site?
    Yes. Every system we deploy on construction sites is 100% solar-powered with lithium battery backup. The batteries are sized for a minimum of 5 days without sunlight, and we monitor battery levels remotely. In over 3 years of deployments, we have never had a site go offline due to power.
    How do PTZ cameras with smart tracking work?
    The PTZ (pan-tilt-zoom) camera continuously monitors the site using preset patrol routes. When the built-in AI detects a person or vehicle, the camera automatically locks on and follows the target across the site while recording. The monitoring centre receives the alert immediately and can take over manual control of the camera to get close-up footage of the intruder.
    How quickly can you deploy security on our site?
    Standard deployment is within 24 to 48 hours of a confirmed order. For urgent requirements — such as after a theft or when insurance demands immediate action — we offer same-day deployment, typically within 6 hours. We keep towers ready to go for exactly this situation.
    What happens when an intruder is detected on site?
    The perimeter sensors or PTZ camera triggers an alert at our NSI Gold monitoring centre. The operator views the live camera feed, confirms the intrusion, and activates the on-site audio speaker to challenge the intruder. If they do not leave, a mobile response team is dispatched to site and police are called. The entire sequence from detection to audio challenge typically takes under 30 seconds.
    Can I view the cameras from my phone?
    Yes. We provide site managers and project managers with secure app access to view live footage, play back recordings, and check site status from their phone or tablet at any time. Multiple users can be set up at no extra cost.
    What are your hire terms and minimum contract?
    We offer flexible hire from 1 month with no long-term commitment. Most construction clients hire for the duration of their build — whether that is 3 months or 3 years. We invoice monthly and you can scale up, scale down, or end the hire with 30 days notice.
    Do you relocate equipment as our build progresses?
    Yes, and this is included in the service at no additional charge. As your site layout changes — new phases opening, compounds moving, access points shifting — we attend site and reposition CCTV towers and perimeter sensors to maintain full coverage. Most of our construction clients need relocations every 4 to 8 weeks.
    Is your monitoring compliant with insurance requirements?
    Yes. All our construction site systems are monitored by an NSI Gold-approved alarm receiving centre. This is the standard required by most commercial insurers and many main contractors. We provide compliance documentation and installation certificates that satisfy insurance and contract security requirements.
