We published six reproducible models covering drone endurance, dock fleet sizing, viewsheds, sensor fusion, probability of interruption and guard-post cost, with the scripts available under Research. One result went against us: perching 2 m above high points did not beat greedily placed 9 m masts on synthetic terrain. We published it anyway.

FAA Remote ID (14 CFR Part 89) for site security: what drones broadcast, standard vs. broadcast-module compliance, how to use Remote ID receivers, and the drones Remote ID will never show you.

https://tencerindustries.com/learn/drone-detection-radar-vs-rf2026-10-30T00:00:00Z

Why small drones are hard for radar (range scales with RCS^¼), what RF detection can and cannot see, Albersheim's equation for detection SNR, and how to combine sensors. Worked numbers and sources.

https://tencerindustries.com/learn/dori-pixel-density2026-10-30T00:00:00Z

IEC 62676-4 DORI pixel densities (25/63/125/250 px/m), the formula for camera distance, worked tables for 1080p and 4K, and how Johnson's criteria relate. With a calculator method.

https://tencerindustries.com/learn/drone-security-regulations2026-10-30T00:00:00Z

What security teams need to know about drone rules in 2026: Part 107 waivers, the proposed Part 108 BVLOS rule, Remote ID under Part 89, EU Regulation 2019/947 and SORA, and counter-drone legal limits.

https://tencerindustries.com/learn/perimeter-intrusion-detection2026-10-30T00:00:00Z

PIDS explained for practitioners: sensor types, probability of detection, nuisance alarm rate, fusion logic, timely detection and coverage design — with models and worked numbers.

https://tencerindustries.com/learn/autonomous-security-drones2026-10-30T00:00:00Z

How autonomous security drones work in 2026: patrol drones, drone-in-a-box, tethered systems and perching sentries compared on endurance physics, weather, regulation, detection and cost.

https://tencerindustries.com/research/guard-post-cost-model2026-10-30T00:00:00Z

From the BLS median wage to an annual cost per 24/7 post: FTE math, burden, markup and a 100,000-draw Monte Carlo comparison with autonomous sentries, including sensitivity analysis.

https://tencerindustries.com/research/probability-of-interruption2026-10-30T00:00:00Z

An EASI-style timely-detection model for a remote substation: how detection placement and response time drive the probability of interrupting an intrusion. Formulas, code and results.

https://tencerindustries.com/research/false-alarms-and-sensor-fusion2026-10-30T00:00:00Z

A Poisson model of perimeter nuisance alarms: OR vs AND fusion, coincidence windows, verification and what one operator can actually handle — with formulas and simulated checks.

https://tencerindustries.com/research/sensor-height-and-placement-viewshed2026-10-30T00:00:00Z

How much ground does a security sensor actually see? A 30-terrain viewshed simulation of mast height, greedy placement and perching — with an honest negative result.

https://tencerindustries.com/research/drone-in-a-box-fleet-sizing2026-10-30T00:00:00Z

A one-year Monte Carlo of drone-in-a-box fleets with wind and rain: the dock count formula, why naive scheduling collapses, and how a perching sentry compares.

https://tencerindustries.com/research/perch-vs-hover-drone-endurance2026-10-30T00:00:00Z

Momentum-theory hover power, perched sensor power and the scaling law that keeps hovering drones near 20–30 minutes regardless of size. With a reproducible model and results.

https://tencerindustries.com/notes#meridian-relief-scheduling2026-10-22T00:00:00Z

Meridian now schedules third-party drone docks with relief timing — launching the next aircraft so it arrives as the current one departs — instead of fixed intervals. Our fleet model showed fixed intervals resynchronizing after weather holds.

https://tencerindustries.com/notes#remote-id-correlation2026-10-09T00:00:00Z

Radar tracks are now correlated with received Remote ID broadcasts. Correlated tracks carry identity and operator location; uncorrelated tracks are flagged non-cooperative and cue the nearest perched sentry.

https://tencerindustries.com/notes#kestrel-perch-power2026-09-18T00:00:00Z

Operators can now trade radar search cadence against days on station per mission. The default profile holds average perched draw under 58 W for a 72-hour sortie.
