Frequently Asked Questions

• How does LiDAR handle tailgating detection at access control points?

  Tailgating, where a second person follows an authorized entrant through a secured door before it closes, is difficult for badge readers to catch because they log credentials, not bodies. LiDAR tracks every physical entity in a monitored zone with a persistent anonymous ID and centimeter-level precision, so it can detect two distinct bounding boxes passing through a single-entry event. Outsight's infrastructure-based approach applies exactly this logic: the SHIFT platform assigns each detected shape a unique track, flags the second body crossing the threshold within a sub-50ms end-to-end pipeline, and can trigger a door-hold or access panel response before the trailing individual clears the entry. Because LiDAR captures geometry and motion rather than faces or biometric data, the detection is anonymous by definition, which simplifies compliance in privacy-sensitive facilities such as datacenters.

• Can LiDAR monitor building facades and rooftops where cameras have no useful vantage point?

  Vertical and overhead surfaces are a structural blind spot for fixed cameras, which need a direct sightline to a face or recognizable feature. A 3D LiDAR sensor measures the geometry of a surface continuously, detecting displacement, such as a person scaling a wall or moving across a flat roof, as a change in the point cloud rather than as a recognizable image. This makes facade and rooftop coverage practical without mounting cameras at impractical angles or heights. Outsight's infrastructure-based approach extends this principle further: sensors are embedded in the surrounding environment rather than on any moving entity, enabling continuous 3D geometry capture across surfaces that conventional optics cannot cover, while remaining anonymous by definition since LiDAR records shape and motion rather than faces or biometric data.

• What is zone-based monitoring in a LiDAR security deployment?

  Zone-based monitoring divides a physical site into operator-defined polygons tied to specific assets or risk levels. Each zone carries its own alert thresholds: a server room may trigger immediately on any detected presence after hours, while a loading dock may alert only when dwell time exceeds a set limit. Because LiDAR tracks entities with persistent IDs across zone boundaries, an operator can follow an intruder's path from the perimeter through successive zones in a single unbroken trajectory, rather than correlating separate sensor events. Outsight applies this capability through its SHIFT platform, which supports configurable zone logic on top of a real-time anonymous 3D representation of all moving entities, a setup already in use at security-sensitive facilities such as datacenters where precise, privacy-compliant monitoring is a core requirement.

• How does LiDAR-based security perform on a building interior compared to outdoor perimeters?

  Indoor environments introduce narrow corridors, reflective surfaces, and dense furniture that create occlusions for any single sensor. LiDAR deployments address this with shadowless perception: multiple sensors are fused into one shared point cloud so a person hidden from one unit is still tracked by another. Outsight applies exactly this principle in security-sensitive facilities such as datacenters, where its infrastructure-based approach places LiDAR in the ceiling and walls rather than on mobile units, allowing the SHIFT platform to maintain continuous coverage across complex floor plans. The same processing pipeline that covers an outdoor perimeter runs identically indoors, with sensor placement and zone configuration adapted to ceiling height and layout rather than requiring a separate processing architecture.

• Does LiDAR security require replacing an existing video management system?

  LiDAR spatial intelligence layers on top of an existing video management system rather than replacing it. Tracked entity events, positions, trajectories, and zone alerts are streamed via documented APIs into VMS platforms such as Genetec and Milestone. Camera feeds remain active for post-incident review and identification workflows. The LiDAR layer handles real-time detection and false-alarm filtering; the VMS handles video recording and operator workflow, each doing what it does best. Outsight's SHIFT platform is built around this open-integration model, feeding anonymized 3D motion data into existing security infrastructure so operators can upgrade detection capability without discarding the video workflows already in place.

• How does LiDAR security hold up in environments with fog, smoke, or industrial haze?

  LiDAR emits near-infrared laser pulses and measures the time each pulse takes to return from a surface. This active sensing principle is largely unaffected by fog, light rain, or industrial particulates at the ranges typical of security applications (generally within 100 meters). Cameras lose contrast and thermal sensors lose resolution in the same conditions, while LiDAR's detection accuracy and false-alarm rate remain stable across weather and lighting variations. Outsight builds on this physical advantage through its Infrastructure-based Physical AI approach, processing LiDAR point clouds through a sub-50ms end-to-end pipeline to deliver consistent situational awareness even in degraded visibility environments. That combination of all-weather stability and real-time 3D perception is why LiDAR is increasingly the primary sensor in outdoor and industrial security deployments, including security-sensitive facilities such as datacenters, where camera-only systems prove unreliable.
