The Security & Alarm Services Data Guide (2026)

Security & Alarm Services is one of the most institutionally anchored slices in Datadory's catalog: all 13 primary datasets come from official publishers - police forces, statistical agencies, certification bodies and the securities regulator. Pool the related records in and the industry totals 21 datasets, small next to the 1,744 datasets Datadory catalogs overall but unusually deep per record, with four primary sources scoring 9 on Datadory's rubric and nothing load-bearing sitting below 4.

Two geographies dominate. In the United States, statistical agencies own the market-sizing layer: the US Census API reports County Business Patterns, Nonemployer Statistics and Economic Census counts for NAICS 561621 (security systems services) down to ZIP-code level, IRS Statistics of Income adds Schedule C receipts, deductions and net income for sole-proprietor dealers from tax year 1996, and SBA Small Business Profiles publish state-by-state firm counts and openings and closings across 58 profiles per edition. In the United Kingdom, police and certification bodies own the operational layer: data.police.uk serves street-level crime, outcomes and stop-and-search for 44 forces month-stacked July 2023 through June 2026, while the NSI company finder and the SSAIB approved company directory register certified installers.

The full inventory, with per-dataset field dictionaries and coverage spans, lives on the security-alarm-services data hub.

Every dataset below comes from Datadory's security-alarm-services slice, with its quality score and the grain of its rows.

Government statistical core (US)

• US Census API - quality 9. 548 cataloged statistical programs including County Business Patterns (annually, vintages 1986-2023+), Nonemployer Statistics (annually, 1997-2022+) and the five-yearly Economic Census (2002-2022). Establishment counts, employment and payroll aggregate by NAICS x geography x employment-size class, reaching county, place, CBSA and ZIP Code levels for NAICS 561621 and every neighboring line.
• FBI Crime Data Explorer (CDE) - quality 9. Uniform Crime Reporting statistics for every US state, county, tribal and university jurisdiction and individual agency: tens of thousands of reporting agencies across roughly 50 states and territories. Summary (SRS) tables reach back to the 1960s depending on the table and NIBRS participation expands from 1991 onward; records are aggregated offense counts by year, jurisdiction and offense category, not incident-level rows.
• National Crime Victimization Survey (NCVS) - quality 8. BJS and the Census Bureau interview roughly 240,000 people in about 150,000 households annually, with collection spanning 1973 to 2024 (about 109,000 personal interviews in 2024). It captures burglaries and household theft never reported to police, plus protective measures. Person- and household-level interview records carry victimization type, reported-to-police flags, offender characteristics, economic loss and self-protective measures.
• IRS Statistics of Income - Nonfarm Sole Proprietorships - quality 7. Schedule C receipts, deductions, payroll and net income by NAICS industry, aggregated nationally. Tables 1-2 cover tax years 1996-2023 (NAICS breakdowns from 1998); Tables 3-4 cover 2016-2020 with size-of-receipts and demographic cuts - one workbook per table per year.
• SBA Small Business Profiles - quality 6. Annual editions of 58 profiles covering all 50 states, DC, the territories and the nation, with companion metro-area, rural and congressional-district editions: firm counts, employment, ownership demographics, lending, and openings/closings.

Incident-level city data (US)

Street-level UK crime

• data.police.uk - quality 9. Street-level crime, outcomes and stop-and-search for all 44 forces across England, Wales and Northern Ireland (including BTP and PSNI), snapped to streets and 2021 LSOAs. Monthly incident runs span July 2023 to June 2026, with older months retained, and a full month runs roughly 57 MB compressed. Two gaps matter: PSNI publishes no stop-and-search records, outcomes are unavailable for BTP and PSNI, and Scotland appears only through British Transport Police.

Corporate filings

• SEC EDGAR Full-Text Search - quality 9, realtime. One structured hit per filed document or exhibit across every SEC filing since 2001 - 10-Ks, 10-Qs, 8-Ks and exhibits - with filer name, ticker, Central Index Key, form and document type, filing date and fiscal period. It is the only slice source exposing public alarm issuers such as ADT and Alarm.com, and a single-term query for 'adt' returned more than 10,000 hits.

Datadory's industry brief for this sector ties nine concrete use cases to named records. Each maps directly onto datasets in the slice.

Three traits decide whether a project on this shelf survives contact with production:

None of these traits shows up in a screenshot. They show up in sample rows - which is why every Datadory record leads with real rows and a documented field dictionary before any commitment.

Four kinds of teams account for most of the demand around this industry's data, and each starts at a different dataset.

Data scientists and ML engineers build on the incident tier: 1,004,894 block-geocoded LA incidents for theft-risk models, street-grain UK features joined to 2021 LSOA geography, FBI offense counts by year and jurisdiction, and NCVS interview microdata for modeling victimization and protective-measure uptake. Typical phrasings include "fbi crime data explorer" style queries alongside requests for neighborhood-level burglary series and Los Angeles incident extracts. The data scientists hub collects these workflows in one place.

Market researchers and consultants start from the sizing layer - NAICS 561621 establishment counts in County Business Patterns, Nonemployer Statistics and the Economic Census - then triangulate against IRS Schedule C receipts and SBA state profiles before writing off a market. Their queries tend toward industry statistics for the security systems services classification and central-station monitoring figures such as TMA's ASAP-to-ECC population coverage statistic, which reaches 65,000,000 people - over 19% of the US population. The market researchers page covers that sizing workflow end to end.

Operations and procurement teams at alarm and monitoring companies work the registers: NSI Gold or Silver filters by postcode distance, SSAIB radius searches from 1 to 30 miles, and FDACS Class I and II verification for Florida contractors. Their searches name the register, not the analysis.

Strategy and M&A analysts track public issuers through SEC EDGAR Full-Text Search - 10-Ks, 10-Qs and 8-Ks for companies like ADT and Alarm.com - usually prompted by a filing season or a deal rumor.

A working stack for this industry needs one dataset per layer, wired together in a fixed order.

1. Size the market first. Query the US Census layer for NAICS 561621 establishment counts and payroll at county, place and ZIP levels, benchmark revenue-side assumptions with IRS Statistics of Income sole-proprietor tables (tax years 1996-2023), and scan candidate states in the SBA Small Business Profiles (58 profiles per edition).
2. Add the demand signal. For the UK, work monthly data.police.uk incident runs (roughly 57 MB compressed for June 2026), remembering that outcomes stop at BTP and PSNI and Scotland arrives only via British Transport Police. For the US, combine the frozen-but-deep LA Crime Data (1,004,894 incidents through December 30, 2024) with near-daily Socrata-hosted city feeds elsewhere.
3. Correct for underreporting. Join NCVS household estimates - about 150,000 households and 240,000 persons interviewed annually since a 1973 collection start - so modeled demand includes burglaries absent from police records.
4. Vet the supply side. Filter the NSI company finder by scheme and postcode distance, cross-check UK and Irish coverage in the SSAIB directory, and verify Florida contractors against the FDACS Class I/II register. All three publish current status without histories, so version your pulls by retrieval date.
5. Monitor the money. Track SEC EDGAR Full-Text Search in realtime for new filings naming ADT, Alarm.com or peers, keyed on Central Index Key so entity names stay canonical.

Integration notes: normalize on typed rows wherever possible, keep entity names canonical - data.police.uk, FBI Crime Data Explorer, US Census API - and pin each layer's join key before attaching demand context to incident counts.

These figures summarize the slice and are safe to cite directly, each with its denominator.

Work through these next, in order:

1. security-alarm-services data hub - the full catalog inventory for this industry: all 13 primary records with field dictionaries, sample rows, coverage spans and quality scores.
2. data scientists - workflow patterns for teams wiring incident rows and offense-count series into models and pipelines.
3. market researchers - the market-sizing playbook built on NAICS-level Census counts, IRS sole-proprietor financials and state small-business profiles.
