The sentry that flies.

Kestrel lifts off like a drone, flies to high ground, anchors and holds the line for up to 72 hours. When the threat moves, it moves. One operator commands the whole fleet from Meridian.

Kestrel redeployable sentry flight profile A Kestrel unit lifts from a vehicle-mounted Roost, transits along an arc, and perches on a ridgeline where it anchors and holds a wide sensor arc.

Towers are where threats used to be.

Fixed cameras and guard posts are mapped by adversaries in a week. Drones see everything but stay up for minutes. Kestrel holds ground like a tower and moves like an aircraft.

LIFT

Launch from anywhere

From a Roost on a pickup, a trailer, a rooftop or a ship's deck. Nine seconds from command to airborne.

PERCH

Take the high ground

Kestrel picks its own perch — a ridgeline, a roof edge, a pylon platform — and anchors on slopes up to 25°.

HOLD

Watch like a tower

Rotors stow, the sensor mast rises and the unit holds a 340° arc on a fraction of the power of hovering flight.

SHIFT

Move before they adapt

Meridian repositions sentries on a schedule, on a detection or on an operator's word. Your posture never stays mapped.

03 — Meridian

One operator. Forty sentries.

Meridian fuses every Tencer machine with the radars, cameras and access control you already own — then asks a human before anything consequential happens.

Questions buyers ask first.

Deeper answers live in our guides — on drone-in-a-box vs. redeployable sentries, security robot cost and autonomous perimeter security.

What is a redeployable aerial sentry?

A redeployable sentry is an autonomous unit that flies to an elevated vantage point, lands, anchors itself and then watches the area like a fixed tower. When the threat picture changes it lifts off and relocates. Kestrel combines drone mobility with the endurance of a fixed sensor — hours to days on station instead of the 30–40 minutes a drone can hover.

Who buys Tencer systems?

Defense ministries and armed forces, law-enforcement agencies, critical-infrastructure operators (utilities, ports, data centers, pipelines), enterprise campuses and private estates. Each segment gets a configuration, payload set and authority model appropriate to its legal environment.

Can Tencer robots use force autonomously?

No. Meridian enforces human authorization for any use-of-force action, for every customer, in every configuration. Civil and residential configurations carry observation and deterrence payloads only. Read our responsible-autonomy doctrine.

How fast can a site be operational?

A typical critical-infrastructure site — two to four Kestrels, a Roost and Meridian — is surveyed, configured and on watch within 30 days of contract. Expeditionary kits deploy in under an hour from vehicle arrival.

How is Tencer priced?

Commercial sites subscribe per sentry-hour, starting at $9.80, with hardware, software, maintenance and upgrades included. Government programs can procure outright with sustainment. Warden for homes starts at $3,900. See pricing.
