What Is 3D LiDAR Perimeter Security? PulseVi FAQs

A conventional camera records a two-dimensional image and uses image analytics to estimate object position and behavior. LiDAR directly measures the distance to points in the scene, producing three-dimensional coordinates. This allows zones to be defined in real-world 3D space and provides accurate target position data. Cameras remain useful for visual verification, so the technologies are often used together.

PulseVi is available in three field-of-view options. A narrower field of view provides greater range, while a wider field of view covers more area at a shorter distance.

*Typical range is based on the datasheet test condition of a 10 percent reflective Lambertian target at 90 klux. Practical detection and classification range depends on the target, mounting position, weather, obstructions, zone geometry and project acceptance criteria. RBtec models coverage from the site plan rather than treating maximum observable range as a guaranteed detection distance.

Yes. LiDAR is an active sensor and uses its own eye-safe laser pulses to measure the scene. It does not require visible lighting to produce a point cloud. Site conditions, obstructions and environmental attenuation can still affect performance and should be considered in the design.

The on-device analytics evaluate target dimensions, movement, speed and direction using the 3D point cloud. Alarms can be limited to configured target classes and behaviors, while objects that fall outside those rules can be ignored. Classification performance depends on having enough visible points on the target and on correct placement, zone design and commissioning.

Wind does not move the laser beam, but it can move vegetation or loose objects within the scene. Rain, snow, dust and fog can scatter or attenuate an optical signal, especially at longer distances or in severe conditions. PulseVi uses 3D filtering and classification to reduce environmental nuisance events, but no outdoor optical sensor is unaffected by every weather condition. Coverage should include the worst credible visibility conditions at the site and the required detection range.

No external analytics server is required for normal detection and classification. Processing runs on the sensor, which reduces the supporting hardware needed at the site. A VMS, alarm platform or Vidalert may still be used for centralized alarm handling, mapping, recording and camera workflows.

PulseVi uses a Gigabit Ethernet connection and consumes approximately 10 W, with typical consumption of 9.5 W and a listed maximum of 10.5 W. It can operate from a nominal 12 VDC supply with a 9 to 20 VDC working range, or through supported PoE equipment. The power method, cable distance, surge protection, grounding and any remote solar-power design should be confirmed in the project bill of materials.
