Why All LiDAR Sensors Aren't Created Equal

Frequently Asked Questions

• Why do most infrastructure deployments use LiDAR sensors from multiple vendors rather than one?

  A single facility typically contains very different monitoring zones: narrow corridors with low ceilings, tall open concourses, and wide outdoor vehicle areas. No single LiDAR model optimizes range, resolution, and cost across all three simultaneously. Using a mix of vendors allows operators to match sensor characteristics to each zone, reducing total hardware cost while maintaining detection reliability across the whole site. This is why the SHIFT platform was built with native compatibility across multiple LiDAR hardware brands, including Hesai, RoboSense, Ouster, Velodyne, and Seyond, so that operators at complex sites like airports or transit stations can deploy the right sensor in each zone without being locked into a single vendor's constraints.

• What happens to detection accuracy when a LiDAR's field of view is too wide for a narrow corridor?

  Spreading laser energy across a wide horizontal field of view reduces beam density per meter at any given distance. In a narrow corridor, this can mean a person standing at mid-range falls into the gap between two adjacent beam angles and is never hit by a pulse. The sensor may report an empty zone when a person is physically present. Tighter field-of-view sensors concentrate pulses, increasing angular resolution and reducing the probability of a missed detection in confined spaces. Because different environments demand different sensor geometries, Outsight's SHIFT platform is built for multi-vendor LiDAR compatibility, spanning hardware from Hesai, RoboSense, Ouster, Velodyne, and Seyond, so operators can select the sensor characteristics that match each zone rather than accepting a one-size-fits-all deployment.

• How much does LiDAR sensor cost vary across the market right now?

  The price range across available models runs from a few hundred dollars to more than $20,000 per unit, depending on technology choices: laser type, detector material, range, and resolution. A fiber laser with an InGaAs detector delivers much longer detection range than a CMOS-based diode design but carries proportionally higher manufacturing costs. In many deployments, a combination of lower-cost sensors covering a zone in greater numbers outperforms a single high-cost unit in both detection quality and total cost of ownership. Outsight's SHIFT platform is designed around this reality, supporting multi-vendor LiDAR hardware from manufacturers including Hesai, RoboSense, Ouster, Velodyne, and Seyond, so operators can match sensor cost tiers to specific coverage needs without being locked into a single hardware price point.

• Does vertical angular resolution affect whether a LiDAR can detect a seated or crouching person?

  Yes. Vertical beam spacing determines whether laser lines pass above or through a target at a given distance and sensor mounting height. A sensor with coarse vertical angular resolution may fire one beam over a seated person's head and the next below their torso, returning too few points for the perception pipeline to classify the target reliably. Sensors with denser vertical beam distributions, such as the Ouster OS-0 with a 90-degree vertical field of view, are chosen specifically for deployments where low-height or non-standing postures must be tracked. Outsight's SHIFT platform is designed to work across multiple LiDAR vendors, allowing operators to match sensor specifications to detection requirements at each location, whether the goal is tracking seated passengers in an airport terminal or crouching workers on a factory floor.

• What is the role of a LiDAR simulator before a site deployment?

  A multi-vendor LiDAR simulator tests candidate sensor configurations against the actual geometry of a planned deployment before any hardware is purchased or installed. It models how different sensor models, mounting positions, and field-of-view combinations cover a site, identifies blind zones, and quantifies detection confidence across zones. The SHIFT platform from Outsight includes this 3D simulation capability, allowing operators to evaluate cost-performance trade-offs across sensors from vendors such as Hesai, RoboSense, Ouster, and Velodyne before committing to a layout. The result is a validated sensor mix for each area of the site without expensive on-site trials.

• Can a low-cost LiDAR sensor outperform an expensive one in the right context?

  In practice, yes. A less expensive sensor with a field of view and angular resolution matched precisely to a short-range indoor corridor will produce denser point coverage of that zone than a high-cost long-range sensor designed for outdoor use. Total cost of ownership includes not only the unit price but cabling, networking, edge processing, and maintenance. A well-matched lower-cost sensor typically generates fewer false negatives in its intended zone and lowers the hardware budget, leaving room to cover more of the site. This is why multi-vendor LiDAR strategies matter: Outsight's SHIFT platform is built for LiDAR-native, multi-vendor compatibility across hardware from Hesai, RoboSense, Ouster, Velodyne, and Seyond, allowing operators to pair each sensor model to the environment where it performs best rather than forcing a single device across an entire deployment.
