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.

• How does LiDAR-based perimeter security reduce false alarms from non-human movement?

  When used with the right spatial data processing software, LiDAR systems can differentiate between human and non-human movements. Outsight states that this reduces false alarms and ensures a timely response to genuine threats. By distinguishing between different types of movements, LiDAR significantly reduces the incidence of false alarms, which Outsight lists among the core advantages of LiDAR technology in security. LiDAR-based computer vision also enhances perimeter security by creating a virtual fence that detects intrusions with high accuracy.

• What is a LiDAR virtual fence and how does it help with perimeter intrusion detection?

  LiDAR-based computer vision enhances perimeter security by creating a virtual fence that detects intrusions with high accuracy. When used with the right spatial data processing software, the system can differentiate between human and non-human movements. Outsight states that this reduces false alarms and ensures a timely response to genuine threats. LiDAR also provides 3D mapping and object detection regardless of rain, fog or darkness. Outsight lists reduced false alarms and centimeter-level accuracy among LiDAR's key advantages in security.

• How does LiDAR-based spatial intelligence track an intruder in real time once detected on a site?

  As soon as a potential intruder is detected on premises, Outsight's Spatial Intelligence based on LiDAR provides their exact location, speed and position in real time. LiDAR technology can track intruders continuously, providing updates on their location and movement.

Outsight's Shift Perception solution is presented as integrating seamlessly with these platforms to fortify overall security.

• How accurate is LiDAR for security monitoring and intrusion detection?

  LiDAR systems offer centimeter-level accuracy, which makes them ideal for precise security applications. They provide high-resolution 3D mapping and object detection that can detect the slightest changes in a monitored area. Combined with Outsight's software, this precision allows the exact location, speed and position of an intruder to be known in real time, and makes it possible to monitor entry points, facades, custom critical zones and perimeters with high reliability.

• Why do traditional camera, thermal and manual security monitoring struggle in some conditions?

  Traditional security systems have relied on a combination of cameras, thermal sensing and manual monitoring to detect and respond to threats. These methods often fall short in challenging conditions such as low light, adverse weather or complex environments, and manual monitoring becomes impractical on large facilities. LiDAR addresses these limitations by providing high-resolution 3D mapping and object detection regardless of external conditions such as rain, fog or darkness.

• Can LiDAR security solutions scale to cover large sites and complex facilities?

  Yes. Scalability is one of the key advantages of LiDAR technology in security: it can be scaled to cover large areas and complex environments, providing flexible solutions for diverse security needs. Outsight describes LiDAR solutions for perimeter surveillance, intruder tracking, facade surveillance, building access control, zone-based critical asset monitoring and interior and roof protection. Intruder tracking is described as indispensable for large facilities where manual monitoring is impractical.

• How does LiDAR help security teams detect suspicious activity in public spaces?

  LiDAR helps improve public safety by creating high-resolution 3D views of public areas that can reveal suspicious activity, track the movements of individuals and identify potential security threats before they occur. Because it can detect the slightest changes in an area, it is a top choice for monitoring applications. With Outsight's software, security teams can analyze public spaces in real time and stay one step ahead of potential threats while keeping infrastructures safe.

From safeguarding critical infrastructure to enhancing public safety, Outsight states that LiDAR is playing a pivotal role in creating safer environments. Outsight lists its advantages as high accuracy, all-weather performance, reduced false alarms, scalability and integration with existing VMS systems.

• What role does processing software play in making LiDAR effective for security?

  Outsight stresses that LiDAR delivers its security benefits when used with the right spatial data processing software. With such software, LiDAR systems can differentiate between human and non-human movements, reducing false alarms. The right combination of LiDARs with comprehensive data processing software like Outsight's can identify unauthorized access attempts and trigger alerts, integrating seamlessly with other security measures such as existing VMS systems.

• What is a virtual fence and how does it work?

  A virtual fence is a boundary defined in software around an area to protect, with no physical barrier. Sensors monitor the space continuously and the system triggers an alert when a person or vehicle crosses the boundary or enters the zone. With 3D LiDAR, the boundary exists in true 3D, objects are classified by size and shape, and alerts include the exact position, which reduces false alarms. Outsight's platform lets operators draw such zones and receive alerts in real time.
