Three monitoring models, three failure modes
Most contracts we audit are mismatched to the property. A high-traffic warehouse pays for self-monitoring it never uses. A low-risk office building pays for an enterprise SOC subscription it doesn't need. Match the model to the actual loss profile and compliance regime, not the model the last vendor sold.
1. Self-monitoring
The system records and pushes alerts to a phone or email. Nobody is paid to watch. Cost: zero or close to it. Best fit: light-risk properties with daytime-only activity and no after-hours valuables. Verkada, Avigilon Alta, Eagle Eye, and Brivo all push mobile alerts by default.
Where it fails: 3 AM events. The owner's phone is on do-not-disturb, the alert lands, nothing happens. The footage is forensic-only at best.
2. Third-party central station (UL 827)
A licensed center receives alarm signals 24/7 and dispatches per protocol. UL 827 sets the floor: 95 percent of signals answered within 90 seconds, 99 percent within 180 seconds, supervised communications, backup operator coverage at peak. Most commercial intrusion alarms (Bosch, Honeywell, DMP) and many video systems route here.
Cost: $30 to $80 per site per month for basic intrusion, $50 to $150 for video escalation. UL 2050 listing (defense contractor, cleared facility) adds an annual inspection and is required for any classified-information facility.
Where it fails: false-alarm fees. Most municipalities charge $50 to $400 per false dispatch, the penalty rises with frequency, and dispatched officers eventually deprioritize the location. SIA CP-01-compliant panels (entry-exit delays, abort windows) cut the rate but don't eliminate it without verification.
3. AI-verified video monitoring
Camera events are filtered by computer vision (person, vehicle, animal, environmental noise) before any human sees them. Verified events route to a remote operator for live audio talk-down or dispatch. Most systems also offer scheduled virtual patrols, with the operator walking the cameras at programmed intervals overnight.
Cost: $150 to $400 per site per month, depending on camera count and patrol frequency. Sites with high-value cargo (TAPA FSR Class A), nonprofits funded under NSGP, healthcare with workplace-violence exposure, and grant-funded education installs increasingly require this model in writing.
Where it shines: false-dispatch reduction (80 to 95 percent in the first quarter), real-time deterrence via talk-down, faster verified dispatch. Where it's unjustified: low-traffic, low-value sites with no after-hours risk.
What the contracts actually cost (and what gets missed)
- Per-site monitoring fee: $30 to $400 per month depending on model.
- Communicator costs: cellular line cards run $300 to $700 installed plus $10 to $30 per month per device. Required for supervised communications under UL 827.
- False-dispatch fees: $50 to $400 per incident depending on jurisdiction and frequency. Add up fast on a multi-site footprint.
- UL inspection: required for UL 2050; annual fee runs $1,500 to $4,000.
- Service truck rolls: $150 to $300 per visit unless covered by a service contract. SDM Magazine's 2024 contract survey shows a 4-hour critical SLA as the commercial norm.
Multi-site rollouts (10 plus sites) usually negotiate 15 to 30 percent off the per-site monitoring rate. The number that doesn't compress is the false-dispatch line. That one is the customer's to manage.
How we walk it
The free consultation pulls the last 12 months of false-dispatch history, the after-hours incident log, current contract terms, and the compliance overlay (PCI, HIPAA, NSGP, TAPA, CMMC, whatever applies). The output is a written model recommendation per site, not one model for the whole footprint. See AI video analytics for the camera-agnostic detection layer that drives most of the verification.
