Live remote security for London truck yards and sites
London sits where Highways 401 and 402 meet, and its industrial parks fill with trailers, food shipments and equipment. Sigma's live agents watch those yards 24/7 and talk intruders down live.
Local and live
Highways 401 and 402, food plants and industrial parks
The London Economic Development Corporation says the city's serviced industrial lands sit next to Highways 401 and 402, with easy access to three U.S. border crossings. The City sells land in its own industrial parks, including Innovation Park north of Highway 401 along Veterans Memorial Parkway, Skyway Industrial Park beside the London airport, Trafalgar Industrial Park and Huron Industrial Park. Rail freight links London to a network of over 14,000 miles across Canada and the United States.
Food processing is one of London's strengths. LEDC counts more than 7,500 people working across 120+ agri-food companies in the city, with large-scale meat processing, frozen foods such as pizza and desserts, spices and alcoholic beverages among them. For a frozen-food or meat plant, one trailer on the lot can hold a full load of finished product, and the docks, refrigerated trailers and equipment around it need watching nights, weekends and holidays.
Sigma's live agents watch London-area yards and sites 24/7. AI person and vehicle detection flags after-hours movement, the agent talks the intruder down live through the site's speakers, and police are called when someone won't leave. Video evidence and a written report follow every incident.

FAQ
London monitoring questions
Can you watch refrigerated trailers and loaded docks at a London food plant?
Yes. Cameras placed on your docks and trailer rows let a live agent watch them 24/7, with AI person and vehicle detection flagging activity after hours. Morning yard checks can include damage inspections, visual seal checks on video and a parking report.
Do you cover sites outside the city, like St. Thomas or Strathroy?
Yes. Sigma covers yards and sites across Ontario. Technicians install the cameras and speakers on site; you provide power, an internet connection and the gate.
Do you have an office in London?
No. Sigma is based in Acton, Ontario, and monitors sites remotely, so there's no guard to schedule. Agents cover nights, weekends and holidays, and every quote costs less than a 24/7 guard.
