From the inventor of 3D lidar

Cam-Lidar fuses state-of-the-art lidar with radar, cameras and thermal in one unit. It finds a drone, identifies it the same way every time and holds the track, day or night. UDL-64 adds acoustic coverage cheap enough to put everywhere, and every unit you network adds range and certainty.

In 2005, David Hall built the spinning lidar that let cars see the road. The next problem is overhead: small, fast, cheap drones that are hard to see, hard to identify and harder to follow.

Cam-Lidar · Sensor-fusion suite

Radar finds it. Lidar knows what it is.

Cam-Lidar fuses a state-of-the-art lidar with radar, cameras and thermal in one unit. Each sensor covers what the others can’t, and AI turns them into one track that predicts where the drone goes next.

  1. Radar

    Finds it

    Reaches far, in any weather, and cues the other sensors.

  2. Lidar

    Resolves it

    Far finer resolution than radar: dense 3D points show its shape, its rotors, its span.

  3. Thermal

    Sees its heat

    Picks out warm motors and batteries against a cold sky, day or night.

  4. Camera

    Confirms it

    A visual check on what the lidar resolved.

  5. AI

    Predicts its path

    One fused track, the same ID every time, and where it goes next.

Fig. 1 — One drone, resolved: radar contact, lidar point cloud, heat signature, camera lock, predicted path. The third target is the first drone again, and it gets the same ID.

One unit holds a track more reliably than any single sensor type can.

Lidar’s resolution is far finer than radar’s, so the system can tell what a target is (its shape, its size, its rotors), not just that something is there, and give the same drone the same ID every time it is seen. Thermal adds its heat, day or night. With every sensor checking the others, the track holds.

Networked

One unit tracks. A network predicts.

Units share one picture of the sky. Add more and three things grow together.

Fig. 2 — Five units cover a site at night and hand one track across it. Switch to one unit to compare.

  1. 01

    Range

    Every unit extends coverage. A drone that leaves one unit’s view is already in the next one’s.

  2. 02

    Reliability

    Overlapping units see the target from different angles, so the track survives terrain, clutter and the loss of any one sensor.

  3. 03

    Predictability

    More viewpoints give a tighter estimate of where the target goes next, and the same ID across the whole network.

UDL-64 · Low-cost acoustic detection

Cheap enough to put everywhere.

Sixty-four microphones in a 24-inch array, with on-device AI that finds drones by their sound and classifies them in real time. It is built to be extremely low-cost, so you can ring a whole site with them instead of guarding a single spot.

UDL-64 is passive: it transmits nothing, so there is nothing to detect. It doesn’t depend on RF, GPS or daylight, and it has no moving parts. One unit covers about 200 meters; networked units reach about 500.

Fig. 3 — Sound reaches each microphone at a slightly different moment; the array turns that into a direction and a class.

Layered defense

Hear it. Track it. Catch it.

Each sensor covers what the other can’t, and together they hand off to a capture system built by our sister company.

Velodyne Space
  1. 01

    Hear it

    Low-cost UDL-64 arrays listen close in, day or night, and are cheap enough to ring a whole site. About 200 m per unit, about 500 m networked.

  2. 02

    Track it

    Cam-Lidar fuses lidar, radar, cameras and thermal into one track with a repeatable ID and predicts where it goes next. Network units to extend it.

  3. 03

    Catch it

    Our sister company, Velodyne Space, brings it down intact in a net, from up to one kilometer away.
