Construction sites are high-risk environments for theft, vandalism and unauthorised access especially out of hours.
OC Services provides construction site security across Surrey with a practical, site-ready approach. We can combine CCTV, intruder alarms, access control and locksmith services into one joined-up plan, so you're not juggling multiple contractors.
Whether you're securing a small residential build, a refurbishment, or a larger commercial project, well help you protect your site, reduce losses, and keep access controlled.
Physical security is still the foundation. We can help with:
- lock upgrades and replacements
- securing temporary doors and gates
- repairs after break-ins or attempted entry
- keyed alike solutions (where appropriate)
- emergency call-outs when something fails
We design CCTV to capture usable evidence and deter opportunistic theft. Typical coverage includes:
- site entrance/exit and delivery gates
- compound and storage areas
- scaffolding access points
- plant and fuel storage
- welfare units and site cabins
Options can include:
- IP or analogue CCTV (best-fit specified at survey)
- remote viewing for site managers
- recording sized for the retention you need
- signage guidance and sensible access permissions
Alarms are ideal for protecting:
- site offices and cabins
- tool stores and containers
- temporary welfare units
- internal areas during refurb works
We can specify systems with:
- door contacts and shock sensors
- PIRs for internal detection
- external sounders for deterrence
- app control for keyholders
- optional monitoring (where appropriate)
If you need to control who can enter certain areas, access control can help manage:
- staff-only zones
- plant rooms and restricted areas
- temporary offices
- multi-trade access and permissions
Depending on the site and timeframe, we can advise on the most practical setup to control access without slowing down the job.
1. Site survey & risk review
we walk the site and identify likely access points, high-value areas and weak spots.
2. Confirm requirements
what you need to protect, who needs access, and how you want to manage it
3. System design
CCTV positions, alarm coverage, access control approach and physical security upgrades.
4. Installation
scheduled around site operations to minimise disruption.
5. Handover & support
we set up user access, test exporting/playback, and offer ongoing maintenance.
