Construction site security cameras, live video monitoring, gate access control and alarms for Texas builders, general contractors and developers. One local team from groundbreaking to handover, since 1990.

A stolen generator or a load of copper wire is only part of the damage. Every theft or act of vandalism on a construction site means reordering, rework and lost days, and those delays ripple through every trade on the schedule. Job sites are open, changing and empty at night, which is exactly what makes them a target.
Alarm Masters gives builders and general contractors construction site security that adapts as the project grows. We cover your perimeter, laydown yard and buildings with cameras, put live operators on watch after hours, control who comes through the gate, and then install the finished building's permanent fire and security systems when you are ready to hand over.
Axis and Hanwha HD cameras covering gates, laydown yards, equipment parking and buildings as they rise, viewable on Eagle Eye cloud video.
Operators and smart analytics watch the site after hours, warn intruders through speakers and dispatch police with verified video.
Credentials for crews and subcontractors at the site gate, with a clear log of who was on site and when.
Alarms for site trailers, tool cribs and finished interiors, monitored around the clock.
Permanent fire alarm design and installation for the finished building, coordinated with your schedule and inspections.
Fire alarm testing, inspection support and documentation for a smooth certificate of occupancy.
Recorded video tells you what was taken. Live video monitoring helps make sure nothing is. Our operators watch your site during the hours you choose, use speakers to warn trespassers off the moment they arrive, and send police verified video when a real crime is in progress, so response is faster and false alarms stay low.
Where construction site security cameras do the most good →Office, retail and industrial builds carry high-value materials and equipment for months at a time. We cover the perimeter, laydown yard and building with cameras, add live monitoring after hours, and control access at the gate so only approved crews are on site.
Subdivisions spread materials and appliances across many lots. Strategically placed cameras with live monitoring protect homes under construction and help stop theft of lumber, copper and appliances before they disappear.
Large vertical projects need coverage at several levels and entrances. We plan cameras and access control that move with the build, then install the permanent fire alarm, access control and cameras residents will rely on.
Remote and large-footprint sites benefit from long-range cameras, perimeter alarms and monitoring designed for wide open spaces, with the same local team supporting the site from start to finish.

“We just used Alarm Masters to do an entire security install at our new commercial site, and I can't recommend them enough. I communicated with the owner and tech manager, directly, through the entire project … We thought the job would take months (as our construction has), and they had it done in 2 days. 5 stars, all the way.”
“Sometimes business owners that communicate really well are some of the best ones to work with. These guys operate quickly, effectively, have attention to detail, and operate with the utmost integrity. I could not ask for anything more in a business.”
The most effective construction site security combines cameras that cover the perimeter, gates and laydown areas with live video monitoring after hours, so someone can respond while an intrusion is happening. Gate access control and alarms on trailers and tool storage complete the picture.
Trained operators watch your cameras during the hours you choose, usually nights and weekends. When someone enters the site, they can warn them through speakers, alert police with verified video and notify your team right away.
Focus on every gate and entrance, equipment parking, the laydown yard, material storage, site trailers and the building itself. As the project progresses, coverage should move to interiors where copper, fixtures and appliances are installed.
