An alarm going off is not, by itself, a reason for police to come. Verified response in California means a growing number of cities now require independent evidence that a crime is actually happening before they will dispatch — an alarm signal alone earns a lower-priority response, or none at all.
Most business owners find this out after the second false alarm, not before.
Why California cities moved to verified response
The reason is volume. The Los Angeles Police Department reports responding to more than 100,000 privately installed burglar alarm calls a year, of which 97 percent are determined to be false — calls that, by the department’s own account, burden both patrol units and dispatchers.
Our own analysis of San Jose’s dispatch records shows the same shape at a different scale: San Jose police handled 21,680 alarm calls in 2025 — about 59 a day — and officers took a report on 102 of them. That’s under half of one percent. The full breakdown is in our review of San Jose’s false alarm data.
That ratio is the entire argument. A department fielding tens of thousands of alarm calls a year, where a tiny fraction involve a documented crime, is going to start asking for evidence before committing a patrol car. This isn’t departments abandoning businesses — it’s departments rationing a finite resource toward calls where something is known to be happening.
What actually counts as verification
The specifics are set city by city, and the differences matter.
Los Angeles is the most explicit. Under Municipal Code §103.206, a property that records two false alarms within a rolling 365-day period moves to verified response — LAPD will require verification of each subsequent alarm before dispatching a unit. Verification can come from a physical response to the property, from a Private Guard Responder, or from remote video. One important exception: the policy does not affect the dispatching of robbery or panic alarms, which are still treated as immediate. Our analysis of LA’s commercial burglary data covers the fee schedule and permit rules that come with it.
Fremont runs a verified alarm response policy that accepts four forms of verification: sound, video, a manually activated panic button, or an eyewitness account that a crime is occurring. Unverified activations receive a lower-priority “be on the lookout” response rather than a dispatch. The context is in our Fremont commercial burglary analysis.
Notice the thread running through both: remote video and sound are accepted verification. A human being does not have to be standing on the property. That single detail is what makes verification achievable for a building that empties out at 6 p.m.
What this means if your building sits empty at night
An unstaffed building cannot produce a physical eyewitness at 3 a.m. Nobody is there to see anything. So for most commercial properties, the realistic path to verification is remote — live video or live audio, observed as it happens.
This is where the distinction between recording and monitoring becomes concrete rather than theoretical. A camera that records to a hard drive produces excellent evidence tomorrow and nothing at all tonight, because at the moment verification is needed, nobody is looking at it. A monitored feed produces a live account: someone watching who can describe what is happening, right now, to a dispatcher.
None of that is a criticism of alarm systems. An alarm is very good at detecting that something happened. What it cannot do on its own is establish that a crime is in progress — and for most commercial properties, meeting a verified response requirement in California comes down to whether someone is watching the cameras at the moment it matters.
The honest limits
A few things worth stating plainly rather than glossing over:
Verification policies vary by city, and they change. Permit requirements, false alarm fee schedules, and the number of false alarms that trigger verified status differ from one jurisdiction to the next — the Los Angeles rules described above are Los Angeles rules, not California rules. A verified call also isn’t a guaranteed response time; verification affects whether police are dispatched, not how quickly they arrive. And no monitoring service can promise police attendance, whatever the marketing says.
The practical step for any business owner is to check your own city’s alarm ordinance and confirm your alarm permit is current. This page is general information about published city policies, not legal advice.
Where Guardian fits
Guardian Integrated Security’s monitoring agents watch a property’s existing cameras live. When something happens, an agent sees it as it happens, challenges the intruder over on-site speakers, dispatches Guardian’s own patrol, and alerts and coordinates with local police using a verified account of a crime in progress — the form of verification these ordinances name.
Our city-by-city analyses of San Jose, Oakland, and Sacramento show the same pattern behind these policies: commercial burglary happens overnight, in empty buildings, and clearance rates are low once it has.

Los Angeles alarm ordinance provisions come from Los Angeles Municipal Code §103.206 and the LAPD Alarm Section, which publishes the verified burglary alarm policy and false alarm call volumes. Fremont’s verified alarm response requirements come from the City of Fremont Police Department’s published alarm policy. San Jose dispatch figures are drawn from the city’s Police Calls for Service dataset, as analyzed in our San Jose false alarm statistics page.
