Flights are operated by FAA-certified pilots under FAA and Washington State operating rules, and the flight plan is reviewed against each contracted property before coverage is proposed. - Question: What about privacy? - Answer: Footage access, retention, and deletion are defined in the client agreement. The operations desk reviews footage only for incident documentation and client reporting. - Question: What if power or the internet goes down? - Answer: If site power or internet is interrupted, a responder remains on site to maintain coverage. Power and connectivity assumptions are also written into the site plan during the property walk. - Question: Do I have to install anything? - Answer: Not always. Some coverage tiers can work with the property's existing conditions, while AI camera monitoring requires the camera plan defined during assessment. - Question: What happens when someone is detected? - Answer: A human operator verifies the alert, a responder assesses the situation on site, and the incident closes with a timestamped report. Police are involved only when warranted — 97% of incidents are resolved on site without them. - Question: Are your responders armed? - Answer: No. Sentinel responders are unarmed and operate no-contact: presence, evaluation, and documentation. Police are brought in only when a situation warrants it. “No scene” is the standard. - Question: How fast can you start? - Answer: Coverage is typically live within 5 business days of the site assessment. The written plan defines what can start immediately and what depends on camera, responder, or drone setup. - Question: How is this different from a traditional guard company? - Answer: A traditional guard covers one post. 911 Sentinel combines responders, cameras, drones on large-acreage sites, human verification, and timestamped records so coverage can be audited. - Question: What areas do you cover? - Answer: 911 Sentinel serves the Seattle metro. The coverage page shows property-crime concentration and how the service footprint is evaluated. ## Research - [97% Closed Without Police. What Actually Happened Instead?](https://www.911sentinel.com/research/incident-closure-without-police): Among 3,486 incidents closed from July 1, 2025 through June 30, 2026, 3,366 did not involve police, and 75.3% of those non-police closures ended in an outcome other than ‘no issue found.’ The useful answer is the outcome mix behind the headline—not the 96.6% alone. - Important limitation: The cohort contains closed incidents and does not describe open or missing records. - Source: internal operational aggregate maintained by 911 Sentinel; methodology and limitations are published with the study. - [Why Two Properties a Mile Apart Can Face Very Different Security Problems](https://www.911sentinel.com/research/repeat-block-concentration): Not by itself. Across 114,934 accepted Seattle property-offense records from July 2023 through June 2026, the highest-count 10% of published blocks account for 56.2% of records while the median block has two. Recurrence can prioritize review, but it is not a property risk score. - Important limitation: A record is not a unique victim, property, call, or future event. - [Official source](https://data.seattle.gov/Public-Safety/SPD-Crime-Data-2008-Present/tazs-3rd5): Seattle Police Department, SPD Crime Data: 2008-Present. - [Does Property Crime Rise After Dark? Midnight Timestamps Change the Answer](https://www.911sentinel.com/research/after-dark-property-offenses): Across 116,814 accepted Seattle property-offense records from July 2023 through June 2026, the recorded night rate is 14.0% above daylight when timestamps are used literally, but it becomes 6.9% lower after 10,156 exact-midnight records are excluded. This dataset does not support a simple sunset rule. - Important limitation: Recorded start time may be estimated or may begin a broader occurrence window. - [Official source](https://data.seattle.gov/Public-Safety/SPD-Crime-Data-2008-Present/tazs-3rd5): Seattle Police Department, SPD Crime Data: 2008-Present. - [100 Security Alerts Come In. How Many Actually Need Action?](https://www.911sentinel.com/research/alert-to-incident-funnel): Across 64,800 alerts recorded from January through June 2026, every 100 alerts produced 77.75 automatic filters, 19.64 dismissals after human review, and 2.61 incident records. Raw alert volume is not the same as reviewer workload or distinct incident volume. - Important limitation: Reached human review is inferred from final stage rather than a dedicated review-start event. - Source: internal operational aggregate maintained by 911 Sentinel; methodology and limitations are published with the study. - [The Crime Map Has a Blind Spot: Last Week Is Not Finished Yet](https://www.911sentinel.com/research/offense-report-data-lag): Among 116,787 Seattle property-offense records published from July 2023 through June 2026 with valid nonnegative intervals, only 44.2% appeared within 24 hours of the recorded offense start and 16.4% took more than seven days. Recent occurrence-date totals should remain provisional. - Important limitation: The extract contains records that were published; it cannot reveal records still absent at extraction time. - [Official source](https://data.seattle.gov/Public-Safety/SPD-Crime-Data-2008-Present/tazs-3rd5): Seattle Police Department, SPD Crime Data: 2008-Present. - [Does Construction Really Attract Theft? Seattle Data Complicates the Story](https://www.911sentinel.com/research/construction-nearby-theft): Across 3,997 eligible Seattle permit projects completed from July 2020 through June 2025 and nearby larceny records through June 2026, no stable direction appears: the 250-meter exposure-weighted active rate is 3.1% below the pre-period rate, the 100-meter ratio is effectively flat, and the unweighted project mean is slightly higher during active permits. - Important limitation: Permit dates proxy project activity and do not establish the timing or intensity of work. - [Official source](https://data.seattle.gov/Built-Environment/Building-Permits/76t5-zqzr): Seattle Department of Construction and Inspections, Building Permits. - [The Five-Minute Average That Leaves One in Ten Waiting Twice as Long](https://www.911sentinel.com/research/response-time-distribution): Among 1,721 valid recorded arrivals from July 1, 2025 through June 30, 2026, half were within five minutes, one in ten took longer than 10.1 minutes, and one in twenty took longer than 12.3 minutes. Plan from the distribution—not the 5.6-minute mean. - Important limitation: The clock begins at dispatch order, not at the initial alert or acknowledgment. - Source: internal operational aggregate maintained by 911 Sentinel; methodology and limitations are published with the study. - [You Have Cameras. Do They Cover the Places That Actually Matter?](https://www.911sentinel.com/research/camera-blind-spots): Across 150 priority points in 30 consecutive property assessments, 25 properties had at least one blind priority point and 62.5% of blind points were attributed to field-of-view or fixed-obstruction problems. Audit the views before adding hardware. - Important limitation: The aggregate covers 30 properties and five predefined priority points per property. - Source: internal operational aggregate maintained by 911 Sentinel; methodology and limitations are published with the study. - [Thermal Cameras Do Not Win Everywhere. They Win When the Light Disappears.](https://www.911sentinel.com/research/thermal-visible-camera-trials): No. Across 720 paired positive trials and 48 negative hours per modality, thermal's sensitivity advantage was 0.6 points in daylight and 24.4 points near darkness, while its observed false-alert rate was 1.76 times the visible rate. The decision is condition-specific. - Important limitation: Generalization depends on the exact hardware, configuration, detector, environment, and annotation protocol. - Source: internal operational aggregate maintained by 911 Sentinel; methodology and limitations are published with the study. - [Last Year’s Hotspot May Still Matter—But It Is Not a Set-and-Forget Security Plan](https://www.911sentinel.com/research/hotspot-persistence): Across 1,918 eligible Seattle blocks in 25 rolling windows from July 2023 through June 2026, 63.4% of eligible top-decile memberships remained elevated 12 months later, while only 32.2% of ever-elevated blocks met the study's stability rule. Use history, but refresh it. - Important limitation: Top decile and stable are analytical definitions, not SPD labels. - [Official source](https://data.seattle.gov/Public-Safety/SPD-Crime-Data-2008-Present/tazs-3rd5): Seattle Police Department, SPD Crime Data: 2008-Present. - [1% of Seattle's Street Segments Hold 28% of Its Property Crime](https://www.911sentinel.com/research/seattle-street-segment-crime-concentration): Across 706,100 Seattle property-offense records from 2008 through mid-2026, 165 street segments — about 1% — carried 27.9% of records, the busiest 10% carried 64.3%, and the same segments stayed on top for 18 straight years. The concentration is sharp, durable, and gives a clear place to look first. - Important limitation: Records are published SPD offense records, not unique events, victims, or forecasts. - [Official source](https://data.seattle.gov/Public-Safety/SPD-Crime-Data-2008-Present/tazs-3rd5): Seattle Police Department, SPD Crime Data: 2008-Present. - [Disorder Reports Jumped 60% While Property Crime Didn't](https://www.911sentinel.com/research/disorder-reports-and-property-crime): Across 925,306 Seattle 311 requests and three years of property-offense records, encampment reports rose 60% and graffiti 57% while recorded property crime stayed roughly flat — and precincts report between 3.70 and 5.37 disorder reports per recorded property crime. Disorder reports measure reporting behavior, not crime. - Important limitation: 311 is a reporting process, not a disorder census; reporting propensity varies by neighborhood. - [Official source](https://data.seattle.gov/resource/5ngg-rpne): City of Seattle, Customer Service Requests (311). - [After Dark, Weather and the Moon Change Little](https://www.911sentinel.com/research/after-dark-environmental-model): Across 116,846 Seattle property-offense records, the night/day ratio is 1.080 as recorded but falls to 0.899 once 10,168 exact-midnight records are excluded. Full-moon days are within 3% of other days, and weather coefficients are near zero—so darkness remains a timestamp-precision question, not a scheduling rule. - Important limitation: Association does not establish that darkness causes offenses. - [Official source](https://data.seattle.gov/Public-Safety/SPD-Crime-Data-2008-Present/tazs-3rd5): Seattle Police Department, SPD Crime Data: 2008-Present. - [Crime Data Is a Process That Runs Late](https://www.911sentinel.com/research/offense-report-lag-survival): Among 116,754 valid Seattle property-offense intervals from 2023 through 2026, the median offense-to-report lag was 32.7 hours, only 44.2% appeared within a day, and 16% took more than a week. Motor-vehicle theft surfaced in 16.7 hours; all other larceny took 65.8. - Important limitation: offense_date is an offense start and can be a broad or estimated window. - [Official source](https://data.seattle.gov/Public-Safety/SPD-Crime-Data-2008-Present/tazs-3rd5): Seattle Police Department, SPD Crime Data: 2008-Present. - [A Response-Time Average Hides Dispatch Delay](https://www.911sentinel.com/research/public-call-response-times): Across 250,000 sampled Seattle calls from 2024, priority-1 calls had a 6.7-minute median response and 52.5% arrived within seven minutes, while priority-2 calls had a 21.1-minute median of which 14.8 minutes was dispatch delay. About 8.8% of calls had no recorded response time. - Important limitation: Response time is queued-to-first-arrival and includes dispatch delay; decompose before comparing. - [Official source](https://data.seattle.gov/Public-Safety/Call-Data/33kz-ixgy): Seattle Police Department, Call Data. ## Canonical Routes -
