Security is a broad industry spanning monitored services, cameras, connected devices, access control, software, installation, and public surveillance. The figures below distinguish company-specific revenue and account measures from international CCTV research and one randomized parking-facility evaluation.

Security Industry Revenue and Recurring-Service Scale
Company filings show how differently the security industry can be measured. ADT’s figures combine monitoring, related services, installation, products, and other revenue, so they describe one major United States-focused operator rather than the whole industry.
| ADT measure | 2022 | 2023 | 2024 |
|---|---|---|---|
| Monitoring and related-services revenue | $4.053 billion | $4.179 billion | $4.293 billion |
| Total revenue | — | — | $4.898 billion |
| Recurring monthly revenue | — | — | $4.177 billion |
Source: ADT Inc. Form 10-K for the fiscal year ended December 31, 2024. The monitoring figures are company revenue, not market totals.
ADT reported approximately 6.4 million security-monitoring service subscribers at December 31, 2024. Subscribers are not necessarily households or devices, and the company’s recurring monthly revenue is a company-defined category.
Other 2024 ADT revenue measures add detail without turning the filing into a camera-only market estimate:
- Security installation, product, and other revenue was $604.969 million in the 2024 fiscal year.
- Installation revenue was $258.760 million in the 2024 fiscal year, and is not limited to cameras.
- Amortization of deferred subscriber-acquisition revenue was $346.209 million in 2024; this is an accounting measure, not cash acquisition spending.
Security Camera and Smart-Device Adoption Statistics
Arlo’s filing provides a global view of connected security-device reach, but shipments and accounts should not be read as active installed devices or unique people. Its registered-account geography covered more than 100 countries.
| Arlo measure | 2023 | 2024 |
|---|---|---|
| Cumulative registered accounts | 8.652 million | 10.8 million |
| Cumulative paid accounts/subscribers | 2.813 million | 4.6 million |
| Annual recurring revenue at year-end | $210.078 million | $257.332 million |
| Total fiscal-year revenue | $491.2 million | $510.9 million |
Source: Arlo Technologies, Inc. Form 10-K for the fiscal year ended December 31, 2024. ARR is a run-rate metric rather than recognized annual revenue.
Arlo had shipped more than 37.4 million smart security devices from its first product launch through December 31, 2024. The filing also reported 10.8 million cumulative registered accounts and 4.6 million cumulative paid subscribers at that date; one account may serve multiple end-users, so these are company-defined populations rather than person counts.
Connected Security Technology Platform Data and Trends
Alarm.com illustrates the platform side of the industry, where software and device ecosystems process activity at a scale that is not equivalent to camera sales. The company reported more than 345 billion data points during 2024 from more than 160 million connected devices.
| Alarm.com measure | 2022 | 2023 | 2024 |
|---|---|---|---|
| Platform revenue | $748.561 million | $824.451 million | $870.587 million |
| Platform share of company revenue | 94% | 93% | 92% |
Source: Alarm.com Holdings, Inc. Form 10-K for the year ended December 31, 2024. Platform revenue includes security, video, automation, and related solutions.
The platform processed more than 345 billion data points during 2024, generated by more than 160 million connected devices. Alarm.com reported $939.827 million in total 2024 revenue, while the platform segment contributed 92% of company revenue; connected devices may include non-security IoT categories.
Access Control and Electronic Security Market Statistics
Access control expands the industry beyond surveillance cameras. Allegion’s global filing includes mechanical and electronic security products and services, while its regional segments include locks, doors, access control, workforce solutions, and software.
| Allegion measure | 2022 | 2023 | 2024 |
|---|---|---|---|
| Total net revenue | $3.2719 billion | $3.6508 billion | $3.7722 billion |
| Americas net revenue | — | — | $3.0124 billion |
| International net revenue | — | — | $759.8 million |
Source: Allegion plc Form 10-K for the year ended December 31, 2024. These categories include products and services beyond surveillance.
Allegion’s 2024 services and software revenue totaled $253.6 million globally, including access control, workforce, maintenance, installation, and software offerings. International revenue increased 3.1% in 2024 versus 2023, a company-reported segment change rather than a market-wide growth rate.
For additional 2023 context, Allegion Americas product revenue was $2.7567 billion and International product revenue was $644.6 million. Product revenue includes security products beyond cameras, so these values should not be combined with camera-market estimates.
CCTV Crime-Prevention and Public-Surveillance Evidence
The National Institute of Justice CrimeSolutions profile summarizes a 2019 meta-analysis of CCTV evaluations. The evidence base covered 76 studies in the overall-crime analysis, including 34 published and 42 unpublished evaluations.
The reviewed studies included 34 evaluations from the United Kingdom and 26 from the United States. Settings included 33 city or town-center locations and 16 residential-area locations; these descriptive categories can overlap across evaluation classifications.
| Outcome or evidence base | Result |
|---|---|
| Overall-crime analysis | 76 studies; 14% lower odds |
| Property-offense analysis | 22 studies; 16% lower odds |
| Vehicle-crime analysis | 23 studies; 16% lower odds |
Source: Practice Profile: Closed Circuit Television (CCTV) Surveillance. The pooled findings combine heterogeneous international evaluations, and odds reductions are not percentage-point crime-rate changes.
The meta-analysis found CCTV associated with a 14% reduction in the odds of overall crime versus control areas. Its property-offense analysis covered 22 studies and found a 16% reduction in the odds of property offenses, while the vehicle-crime analysis covered 23 studies and found a 16% reduction in the odds of vehicle crime.
Security Camera Evaluation Outcomes and Measured Limitations
A separate NIJ profile reports a randomized evaluation of cameras in Washington Metropolitan Area Transit Authority commuter-parking facilities. Its treatment and comparison changes show why one local evaluation should not be generalized to every deployment.
| Measure during the post-installation evaluation period | Treatment facilities | Comparison facilities |
|---|---|---|
| Change in all crime | -6.42 incidents; more than -11% | -4.67 incidents; -7% |
| Change in property crime | +1.58 incidents | +3.42 incidents |
Source: Program Profile: Camera Use to Prevent Crime in Commuter Parking Facilities (Washington, D.C.). The treatment results were not statistically significant relative to comparison facilities.
All crime fell by more than 11% in treatment facilities and by 7% in comparison facilities. The treatment facilities saw all crime fall by 6.42 incidents, compared with a 4.67-incident fall in comparison facilities, while property crime increased by 1.58 incidents in treatment facilities and 3.42 incidents in comparison facilities.
These results are facility-level findings from one randomized evaluation, not a universal camera effect. The broader CCTV evidence also combines different designs, settings, countries, and intervention implementations, so measured outcomes depend on the deployment and evaluation context.
