Hall Lidar launches low-cost acoustic system to detect drones
Hall Lidar has launched the UDL-64, a drone detection platform that uses acoustic sensing for counter-UAS missions and covert monitoring.
The U.S.-based sensing company said the product is its first-generation acoustic drone detection system. It is designed to deliver real-time 3D situational awareness in complex operating environments, where small aerial threats are becoming harder to track and classify. The company said the platform uses AI-driven processing to turn acoustic inputs into actionable detection data, aiming to spot drones without relying only on more exposed traditional methods.
Hall Lidar is positioning the UDL-64 as a lower-cost option for counter-UAS deployments while highlighting its stealth role. The company said the system uses advanced acoustic technology and radar to improve detection precision in cluttered environments. It also stressed that the platform is manufactured in the United States, a point likely aimed at government, defense and critical infrastructure buyers that are placing greater weight on supply-chain security and domestic production.
The launch comes as the spread of small, inexpensive and low-flying drones puts new pressure on security operators at airports, energy sites, borders and other sensitive facilities. An acoustic-based layer, if proven in field use, could add a covert and potentially more affordable detection option for sites that need faster warning without increasing their own emissions signature. That points to a broader shift in the counter-drone market toward multi-sensor systems that balance cost, precision and operational discretion.
