What matters in perimeter protection
A LiDAR measures actively with its own laser and, regardless of ambient light, delivers a 3D point cloud from which an object's position, distance and size can be determined. That lets you define alarm zones in space. These are the points that decide the choice:
- Range at low reflectivity: Dark clothing and vehicles reflect little. The Avia 2 is specified at 400 m at just 5% reflectivity.
- Field of view or range: An open area needs a wide field of view, a fence line or access road a long, narrow corridor. The Avia 2 switches between the two.
- Weather: 1535 nm is scattered less by rain, fog and dust than 905 nm, so the sensor copes better with weather — though no LiDAR is immune.
- Blind zone: The area directly in front of the sensor is not captured; on the Avia 2 that is 5 m (at 80% reflectivity). This determines mounting position and overlap.
- Continuous operation: Ingress protection, temperature range, power draw and maintenance, for example because of a fan.
- Eye safety: In public spaces especially, an eye-safe rating matters; all LiDAR sensors on this page are laser class 1.

Prices net, plus 19% German VAT and shipping. Specifications as stated by the manufacturer and listed on our product pages. Laser class 1 for the Avia 2 and Avia 2 NF per IEC 60825-1:2014. As of November 2026.
Livox Avia 2 — area and distance with one sensor
In normal mode the Avia 2 covers a large area at 80° × 80° with 350,000 points per second. In focus mode it concentrates the same laser power into 15° × 15° and reaches ≥ 800 m at 10% reflectivity. Three echo modes and the non-repetitive scan pattern also capture partially obscured targets behind vegetation or fencing. The housing is rated IP66 and the fan IP55, with an operating range from −20 °C to +65 °C. The Avia 2 is in stock.
Livox Avia 2 NF — fanless and shallower
Optics, laser and measurement performance are identical to the Avia 2. Without a fan, one wear part is gone; the sensor is 36 mm shallower and draws 45 instead of 50 W. Passive cooling does, however, limit continuous run time at high ambient temperatures: if it gets too warm inside, the sensor stops and resumes by itself once it has cooled down. Livox requires mounting on a metal plate at least 3 mm thick, with at least 50 mm of clearance at the sides and 150 mm above. The Avia 2 NF is in stock.
Add-on: a Hanwha PTZ camera for verification
The LiDAR detects and locates; the camera supplies the picture. The Hanwha Wisenet QNP-6250H (€1,300 net) offers 2 MP, 25× optical zoom, 360° endless pan, built-in analytics such as virtual line and enter/exit, ONVIF S/G/T, PoE+ and an IP66, IK10 and NEMA4X housing. The coupling — for example a LiDAR alarm that turns the camera to a preset position — is handled by your control-room or video management software.
Livox Tele-15 — narrow corridor, sold out
A 14.5° × 16.2° field of view, 320 m at 10% and angular accuracy below 0.03°: the Tele-15 watches a narrow strip over a long distance. It is sold out and available on request only, with no lead time and no delivery guarantee. For new projects, the Avia 2's 15° × 15° focus mode covers a comparably narrow field of view.
Integrating LiDAR for perimeter security in practice
Mounting
Mount the sensor on a stable mast or wall and aim it so that the monitored zone starts beyond the 5 m blind zone. Cover gaps right at the mast with a second sensor or the camera. For the Avia 2 NF, the mounting requirements for heat dissipation apply.
Power and network
Both Avia 2 versions run on 9–27 V DC; the Avia 2 draws a steady 50 W, the NF 45 W and 50 W at startup. Data runs over 100 Mbit/s Ethernet. For cable runs beyond 100 m, the limit for copper Ethernet, plan a switch or media converter.
Software and alarms
The LiDAR delivers point clouds; detection, tracking, alarm zones and alarm forwarding come from software — your own or a security technology provider's. For the Avia 2, the livox_ros_driver2 driver includes dedicated launch and configuration files and builds on Livox-SDK2. The repository does not list the Avia 2 NF separately; please clarify integration with us before your project starts. The Tele-15 uses the Livox SDK with livox_ros_driver or livox_ros2_driver.
