Remote port and yard monitoring in Saint John
From the container terminal on Saint John's west side to the Irving Oil refinery, Sigma's live agents and AI cameras keep watch over truck yards, warehouses and construction sites around the clock.
Local and live
From the West Side terminal to Spruce Lake
Port Saint John's west side container terminal, run by DP World, handled 239,364 TEUs in 2025, up 29.4 percent from 184,879 TEUs in 2024, after a $247 million modernization project that gave the terminal more than four times its old capacity. Rail service reaches CPKC, CN and CSX through NB Southern Railway, and the Irving Oil refinery nearby processes more than 320,000 barrels a day on a 780-acre site, Canada's largest refinery. Across the harbour, Spruce Lake Industrial Park sits a kilometre from Highway 1 and ten kilometres from the port, with a heavy-lift tidal barge terminal and tenants that include Saputo and Day & Ross.
Construction sites in the city have had a rough stretch. In September 2025, developer Kevin McDonald told Global News his company had spent more than $100,000 on security over 18 months after repeated break-ins, thefts and threats at a Cliff Street project, and a separate Harding Street site was broken into twice within 48 hours, with windows, tools and wiring taken or destroyed. Near the port or the refinery, the exposure is the same once the gate closes: loaded trailers, tools and materials left unattended overnight.
Sigma backs that up after hours. Every camera on a Saint John yard is watched live, all day, every day of the year, and when AI detection spots a person or vehicle, an agent is already checking the footage. A live, instant talk-down goes out through the site's speakers, police and fire services get called in if needed, and you're left with video clips and a written report. Gate Operations can add driver checks against your pickup lists before the gate opens, and Yard Operations covers trailer damage inspections and visual seal checks on video.

FAQ
Saint John, New Brunswick monitoring questions
Can you watch a trailer yard near the West Side container terminal or Spruce Lake?
Yes. Agents watch every camera on the yard live, 24 hours a day, 365 days a year, whether it's beside the port, the refinery or Spruce Lake Industrial Park. AI person and vehicle detection flags movement, and the agent handles it from there with a live, instant talk-down and a call to police if needed.
Can agents check trucks and trailers moving in and out of our Saint John yard?
Yes, with Gate Operations. An agent sees each truck arrive, speaks to the driver through the gate speakers, checks them against your rules, schedules or pickup lists, and opens the gate remotely. Every entry and exit gets logged with the time, and drivers who aren't on your list are turned away.
Sigma is based in Ontario. How does setup work for a Saint John site?
Monitoring is remote and works anywhere with an internet connection, so the distance from Ontario doesn't matter. Sigma's technicians travel to your site to install the cameras and speakers, and many compatible cameras already in place can be connected instead. You provide the power, the internet connection and the gate.
