Between 2 p.m. on a Saturday and 7 a.m. the following Monday this August, thieves cut a locked perimeter gate at a Hydro One yard in St. Clair Township and drove off with spools of copper wire. Lambton OPP put the value at about $1 million, according to the Petrolia Lambton Independent. Police later asked anyone with dash or security camera footage to come forward.

A 41-hour window. A cut gate. A heavy truck. That is the classic weekend exposure at a large industrial yard, and it leads to a question every operations director eventually asks: should we put a guard on site, or invest in cameras and remote video monitoring?

The answer is usually “both, in the right ratio.” But it helps to start with the numbers.

What Does a 24/7 Guard Post Really Cost in Ontario?

A single post staffed around the clock, every day of the year, covers 8,760 hours. Federal Job Bank data puts the median hourly wage for security guards in Ontario at $20.00. Ontario’s general minimum wage rose to $17.95 on October 1, 2026, according to the Ontario government.

Run the math on wages alone:

• At the $20.00 median: about $175,200 per post, per year.

• At the $17.95 minimum: about $157,000 per post, per year.

That is before overtime, statutory holidays, supervision, training, vehicles, insurance and the contract firm’s margin, all of which push billed rates well above the wage. And it buys one person, at one location, with one pair of eyes. On a 40-hectare rail yard, refinery tank farm or trailer lot, that person might be a 10-minute walk from the fence line that just got cut.

What Can a Guard Do That Cameras Cannot?

Guards bring things cameras genuinely do not. They provide a visible human deterrent. They handle access control with judgment, manage visitors and contractors, respond physically to alarms, deal with medical emergencies and handle situations that need a conversation.

At sites with heavy daytime contractor traffic, such as an energy facility during a turnaround or a large construction project, an on-site presence is often non-negotiable.

The weakness is coverage. Patrols are periodic by design. A crew watching a yard from outside can time a patrol loop in one night. Fatigue on long overnight shifts is real, and it is no reflection on the people doing the job.

How Does Remote Video Monitoring for Ontario Industrial Yards Work?

Remote video monitoring for Ontario industrial yards pairs an on-site camera system with analytics and a monitoring centre that watches alerts, not hours of live feeds.

A typical setup on a large yard looks like this:

• Analytics-enabled perimeter cameras with virtual tripwires along fences and gates. Thermal cameras detect people in complete darkness.

• PTZ cameras that automatically swing to follow a detected intruder.

• An industrial NVR that records everything and pushes verified alarm clips to the monitoring centre within seconds.

• Two-way audio and strobes so an operator can challenge intruders live: “You in the grey hoodie by the north fence, police have been called.”

• An escalation plan that dispatches police, a mobile patrol or an on-call supervisor with verified video, which tends to get a faster response than an unverified alarm.

Because the system watches the whole perimeter continuously, it covers the gap that kills patrol-only models: the 20 minutes between rounds. And because a monitoring centre spreads its staff across many sites, the cost per site is typically a fraction of a dedicated 24/7 guard post. Get quotes, since pricing varies with camera count, hours monitored and alarm volume.

When Does a Hybrid Model Make the Most Sense?

For most large industrial operators, the best value comes from rebalancing, not replacing.

Daytime: guard plus cameras. Keep a guard or gatehouse attendant during operating hours for visitor management, contractor sign-in and gate control. Cameras with licence plate recognition at the gate give them a log of every truck without manual entry.

Nights and weekends: remote monitoring first. Shift overnight perimeter protection to analytics and a monitoring centre, with a mobile patrol on call for verified events. The Hydro One case happened over a weekend, exactly when on-site staffing is thinnest.

Turnarounds and peak periods: scale up. Add temporary guard hours and portable camera towers during shutdowns, peak season or major construction phases.

The savings from converting one overnight post can often fund a significant share of a well-designed camera system within the first couple of years, depending on site size and pricing. More importantly, the yard gets continuous coverage instead of periodic coverage.

What Else Do Operations, Safety and HR Get From the Camera Side?

A guard’s notebook rarely helps the plant manager. A 64-camera system does.

The same cameras that watch the fence at 2 a.m. show yard congestion at 2 p.m., reveal where trailers sit too long, verify that lockout or hot-work permits are being followed in camera-covered areas, and give safety teams real footage for coaching. For energy companies like Enbridge, Suncor or Imperial Oil, and for rail operators like CN and CPKC, that operational intelligence is often worth as much as the theft prevention.

It also changes how your own people experience night shift. Workers in a large, dark yard feel safer when they know someone is watching the perimeter in real time. That matters for retaining experienced operators.

ForceVision helps large industrial sites across Southern Ontario model the right balance between on-site guards, cameras and remote monitoring. If you would like a side-by-side comparison for your yard, we can put one together after a no-pressure site walk.

The Takeaway

Pull last year’s security invoice and divide it by the number of hours your perimeter was actually watched end to end. Then ask what happened on site between patrol rounds on your three quietest weekends. If you cannot answer that, it is time to price remote video monitoring for Ontario industrial yards alongside your guard contract, not instead of it.

FAQ

Q: Can remote video monitoring fully replace security guards?
A: At some low-traffic sites, yes, for overnight coverage. Most large industrial sites get better results from a hybrid: guards for daytime access control and response, cameras and remote monitoring for continuous perimeter coverage.

Q: How fast can remote monitoring respond to an intrusion?
A: Analytics typically flag an intrusion within seconds, and an operator can issue a live audio warning and escalate to police or patrol with verified video almost immediately.

Q: Does video verification improve police response?
A: Verified video showing a crime in progress gives police clearer information than an unverified alarm, which often supports a faster, better-informed response.

Q: How many cameras does a large yard need for remote monitoring?
A: It depends on perimeter length, gates and layout. Large rail, energy and logistics yards commonly need 32 to 64 or more cameras, with thermal and PTZ units on the perimeter.
