Most monitoring watches the gate. We watch the whole yard.
Many monitoring companies have one person watching dozens of sites at once, and they only look closely after an alarm, so the gate gets all the attention. Intruders rarely use the front gate.
- Dedicated agents who know your site. The same team watches your property every shift and gets to know your staff, drivers and routines.
- AI that ignores the noise. Agents are alerted to people and vehicles, not wind, rain or animals, so real threats get full attention.
- No blind spots. Auto-tracking PTZ cameras with virtual trip-wires follow movement anywhere on the property.
- We stop it before it happens. Live voice-down through on-site speakers warns intruders off before damage is done.
How it works
From first movement to final report
Every alert follows the same path, handled by a real person, around the clock.

The difference
Guards, typical monitoring, or Sigma
On-site guards only see what's in front of them. Basic monitoring waits for an alarm. Sigma watches everything, all the time.

FAQ
Questions, answered
How is remote monitoring different from hiring a security guard?
A guard can only see what's in front of them. Our agents watch every camera on your property at once, backed by AI that flags people and vehicles, and they can warn intruders off through on-site speakers. There are no breaks, sick days or injury liability on your site, and it costs less than on-site guards.
What happens when someone comes onto my property?
Our AI detects the person or vehicle and alerts your dedicated agent, who checks the live video. If it's a threat, the agent issues a live voice-down through your speakers, and escalates to police and your team if needed. Every incident is logged with video clips and a written report.
Can you use my existing cameras?
In many cases, yes. We can connect compatible existing cameras to our monitoring platform, and add AI, PTZ auto-tracking or 360° cameras where coverage is missing. Your free assessment will tell you exactly what's needed.
Do you install the equipment?
Yes. Our technicians design and install cameras, speakers and gate hardware, and we handle ongoing support and maintenance.
Can I watch my cameras myself?
Yes. You can view live and recorded video from your phone or computer, get real-time alerts, and request footage for any time period or incident.
Can Sigma manage my gate and visitors?
Yes. We manage gates remotely with ID verification, facial recognition, licence-plate recognition and two-way communication, and log every entry and exit.
Which areas do you serve?
We serve Ontario, Montreal and Quebec, and California, and we're expanding across Canada and the United States. If your site is somewhere else, ask us.
Can remote monitoring lower my insurance premiums?
In some cases, yes, but it depends on your insurer. Check with your insurance provider about available discounts and requirements; we're happy to provide documentation of your monitoring setup.
