Key takeaways
- O.W.L.’s manufacturer documentation identifies the GA1360LH as an upgraded short-range, 360-degree 2D digital multi-beamforming radar.
- The published specification lists a 1.25 km instrumented range, 1 km vehicle detection range and 500 m walker detection range; actual performance depends on mounting height and line of sight.
- The radar is intended to classify humans, animals and vehicles, enabling alarms by target type and configured alarm zone.
- For integrators, the practical value is radar-led detection and cueing of cameras, alarms, lighting, access-control and management platforms rather than replacing visual verification.
Upgrade is confirmed, with a date clarification
Observation Without Limits (O.W.L.) has updated its GroundAware GA1360LH, a short-range 2D radar designed to provide 360-degree surveillance around critical-site perimeters. The manufacturer’s current GA1360LH specification sheet explicitly labels the product as “now upgraded,” while the company’s GroundAware product page lists it as a current 2D model for perimeter protection. ([owlknows.com](https://www.owlknows.com/wp-content/uploads/2023/03/OWL-GA1360-2D-Radar-spec-sheet-1.pdf))
The reported event date of August 28, 2026 is the publication date of a trade-media report describing the upgrade. O.W.L.’s public product page was already carrying the GA1360LH model on March 13, 2026, so the available evidence supports treating August 28 as the date the update was reported publicly—not necessarily the model’s first availability date.

Published performance figures require careful reading
The GA1360LH uses simultaneous multiple beams and pulsed-Doppler processing in the S band, from 3.0 to 3.3 GHz. O.W.L.’s specification lists 360 degrees of azimuth coverage, a 40-degree elevation field of view, adjustable 5 m or 10 m range resolution, and a software-defined update rate of 1 Hz to 5 Hz. ([owlknows.com](https://www.owlknows.com/wp-content/uploads/2023/03/OWL-GA1360-2D-Radar-spec-sheet-1.pdf))
For detection, the spec sheet states a 1.25 km instrumented range, with listed detection ranges of 1 km for a vehicle and 500 m for a walker. O.W.L. also presents the system as covering up to 750 acres or 300 hectares from one radar. Those figures should be used as design inputs rather than guaranteed site results: the manufacturer specifically notes that reaching maximum detection range depends on sufficient mounting height and clear line of sight, particularly for ground targets.

This distinction is important during bid review. “Instrumented range” describes the radar’s measurement envelope, while the published target-detection distances vary by target type. Terrain, structures, fencing, vegetation, radar placement and nuisance-motion sources should be assessed during a site survey and acceptance test.
Radar is intended to trigger a layered response
The GA1360LH is positioned as a detection and tracking layer rather than a standalone visual-assessment tool. O.W.L. says the system can distinguish among people, animals and vehicles, apply customizable alarm zones, and initiate automatic response actions. Its published integration examples include cameras, video management systems, access-control systems, audible alarms, security lighting and drones. ([owlknows.com](https://www.owlknows.com/wp-content/uploads/2023/03/OWL-GA1360-2D-Radar-spec-sheet-1.pdf))
For video-surveillance teams, the central design pattern is radar-to-camera cueing. A radar event can direct a PTZ or bring an operator to the relevant camera view, while recorded video supplies the visual verification that radar alone cannot provide. O.W.L. describes GroundAware more broadly as supporting integration with HD and infrared cameras, VMS, access control, PSIM or event-management systems, along with alarms and lighting. ([owlknows.com](https://www.owlknows.com/groundaware/))
Fit for open and mixed land-water perimeters
O.W.L. identifies the GA1360LH for ground and water-surface applications. Its spec sheet names logistics and manufacturing facilities, airports and seaports, correctional and school campuses, electrical transmission substations, water reservoirs and treatment plants, natural-gas facilities, wind and solar sites, and oil-and-gas sites. The company says it can be mounted on towers, poles, buildings and mobile platforms. ([owlknows.com](https://www.owlknows.com/wp-content/uploads/2023/03/OWL-GA1360-2D-Radar-spec-sheet-1.pdf))
The update is therefore most relevant where conventional fixed-camera coverage is difficult to maintain across broad, dark or weather-exposed approaches. The radar does not eliminate the need for cameras, illumination, communications resilience or response procedures; instead, it can reduce the number of locations requiring continuous visual attention by generating events around selected targets and zones.
What installers and procurement teams should validate
A specification should separate the radar’s detection task from its verification and response workflow. Confirm the planned mounting height, fields of view, line-of-sight obstructions, alarm-zone geometry, network path, time synchronization, VMS or PSIM integration method, camera cueing behavior and the required operator response. Acceptance criteria should state target type, approach route, expected detection distance and the allowed nuisance-alarm rate.
The published hardware figures include 35 W power draw, 35 lb weight, passive heating and cooling, and an operating-temperature rating of minus 20 degrees C to plus 60 degrees C. These data points help with pole, enclosure, power and environmental planning, but project teams should obtain the current submittal package and confirm interoperability details before procurement.
