How Much Does Construction Site Security Cost?
A useful comparison starts with the job each option must perform, then uses written quotes for the same hours and scope.

Start with the Security Job
Construction sites may need perimeter visibility, access control, overnight response, equipment records, incident documentation, or a combination. A guard, fixed camera system, mobile surveillance trailer, lighting, fencing, and access control solve different parts of that problem.
Mobile Trailer Starting Price
Complete Security Rental monthly trailer rentals start at $2,750. Available categories include solar power, cellular connectivity, fixed or PTZ cameras, alarms, recording, remote access, audio options, and professional monitoring. The proposal identifies what is selected for the site.

For a guard quote, specify the posts, hours, qualifications, supervision, holidays, and relief staffing. For a trailer quote, specify the areas covered, camera and alarm configuration, monitoring hours, response plan, recording access, delivery, setup, and support. Do not assume either option supplies capabilities that are absent from the quote.
Insurance and ROI
Do not add an assumed premium discount or theft-loss avoidance amount to the calculation. A broker or carrier decides insurance treatment, and no security measure can guarantee that an incident will not happen. Use your own approved budgets and loss data when making a financial comparison.
