Securing correctional facilities from drone-enabled threats.
The rise of unauthorized drone threats presents significant challenges to the security and safety of prisons and correctional facilities. Drones are increasingly used to smuggle contraband, conduct surveillance, and facilitate escape attempts, undermining prison security measures.
Criminal organizations and individuals exploit drones to deliver prohibited items such as drugs, weapons, and mobile phones into prison grounds. These illicit deliveries compromise inmate rehabilitation efforts, escalate violence, and pose risks to both staff and prisoner safety.

| Mounting | Fixed mast or tripod installation |
The station installs as permanent infrastructure: a mast or tripod carries the antenna array and the control unit is mounted alongside it. Siting does most of the work. A clear line of sight from a high point on the perimeter gives the most useful coverage, because walls, cell blocks, water tanks and mature trees all cast radar shadows that have to be worked out from a site plan rather than guessed at. That review is what turns a coverage figure on paper into a footprint that fits your grounds, and it is where any permanent installation should start.
A vertical antenna array is carried on a mast or tripod, with a white radome at the top and a grey control unit mounted at the base. It is built as a permanent anti drone solution rather than something that is set up and packed away, so it sits alongside lighting columns and camera masts on a perimeter.
A handheld unit is carried by a patrol officer and used for a spot check of one area. This station stays on watch from a fixed point and carries its own drone jammer, so the site does not depend on someone being in the right place with the right device. Many teams use both: the fixed station for the perimeter, handheld units for verification beyond it.
Yes. This anti drone equipment detects by radar, so darkness, fog and heavy rain do not blind it the way they limit an optical camera. The station is built for unattended operation through long shifts, and the control room only needs to look at it when something is actually crossing the perimeter.
It goes further: the direction-finding section measures the bearing of the control link as well as the aircraft, so an operator gets a direction to work from instead of a general warning that something is up there. That bearing is what a response team needs when the launch point turns out to be outside the wall.
Yes. The station is usually planned as one layer in a wider setup rather than a replacement for everything else. It can feed a control room alongside existing cameras, radar and counter UAS equipment, so operators keep a single picture of the airspace instead of switching between systems. Send us what you run and we will confirm how it fits.
Multiple aircraft are tracked as separate targets, each with its own path and bearing, so a group flight does not collapse into one alarm. This anti drone defense system keeps the tracks apart through the incident, which matters when a drop attempt is flown by two or three machines at once.
