Crane Climbing Detection, Backed by 24/7 Live Monitoring

Crane climbing detection is an add-on to our 24/7 live video monitoring. Cameras watch the base and mast of your tower crane. AI flags anyone who gets close, and a trained, licensed operator checks the live video and talks them down before they get far.

Secure Defence has protected job sites since 2015. Live video monitoring is what we do. Our operators watch your cameras live from our own command centre in Richmond, BC, and they step in the moment something is wrong. We're the Fastest Growing Security Company in Canada, the highest-ranked security company on both The Globe and Mail and BIV growth lists for 2025 and 2026. We have 500+ customers and 1,000+ sites live monitored across Western Canada. Metro Vancouver is our home market, and construction site security is one of our two biggest areas of work.

Why crane climbers are a GC's biggest liability

Crane climbing has become a dare for thrill-seekers. People climb at night, film it on their phones and post it online. A fence slows them down, but a fence can't see them or speak to them.

For a general contractor, one climber can turn into a lot of trouble:

  • Injury or death on your site. If someone falls, it happened on your project, and questions about how your site was secured follow.
  • Stop-work and investigation. A serious incident can bring a WorkSafeBC investigation and a stop-work order. Every day the crane sits idle costs you schedule.
  • Rescue and police time. A person stuck up a crane means a rescue, and your site may be closed while it happens.
  • Your name in the news. Climbing videos spread fast, and the company name on the hoarding is in every shot.

The best time to stop a climber is before their feet leave the ground. That's what this service is built for.

How it works with your live video monitoring

AI detects a person at the crane base or mast

We set detection zones around the crane base, the mast and the ladder. Our AI detection picks out a person entering those zones during your monitored hours, and the alert goes straight to our command centre.

Richmond operator verifies on live video

A trained operator looks at the live video right away. Is it a climber, or the site super doing a late check? Birds, blowing tarps and swaying lights don't get escalated, because a person checks every alert. That's how we keep zero false alarms.

Live voice-down, strobes and siren

If someone shouldn't be there, the operator speaks to them through an on-site speaker: "This is private property. Get off the crane and leave now." If they keep going, the siren and strobes come on. Our voice-down and audio deterrents end most attempts right there.

Police dispatch with verified video and an incident report

If the person keeps climbing or won't leave, a supervisor calls police with a description of the person and where they are on the crane, and stays on the line until help arrives. This is Verified Police Response: police hear from a person who is watching it happen, not from an unconfirmed alarm. Our verified response takes about one minute. You get an incident report with operator notes and HD video for your safety, insurance and legal files.

Camera placement: base, mast and jib views

Good crane coverage starts at the ground. We usually place cameras to watch:

  • The crane base and ladder access, where every climb starts.
  • The mast, so operators can follow anyone who gets past the first section.
  • The approach routes, such as hoarding gaps, laneways and neighbouring roofs.

Cameras go on wooden or metal poles or on the structure, and run on site power. Every powered site gets a 24-hour backup power system, so an outage doesn't leave the crane blind. Our equipment is rated to -40°C for winter work. Pole cameras go live in 5 to 7 days, and if you already have cameras, they can connect to our command centre the same day.

Part of your site plan

Crane coverage works best as one part of a monitored site. The same operators watch your perimeter, gate and equipment, so a climber who came over the fence is usually spotted before they reach the crane.

High-rise projects across Vancouver and Western Canada

Most of our crane work is in Metro Vancouver, where towers go up in Vancouver, Burnaby, Richmond and Surrey. See our Vancouver construction site security page. We also cover high-rise and mid-rise projects across Western Canada, including Calgary and Edmonton.

Crane risk isn't only a construction issue. If you manage a mixed-use project or a building beside an active site, see our strata and property management security and commercial and industrial pages.
