White Paper Overview

Depth sensing is becoming a foundational technology in smart buildings, enabling more accurate occupancy monitoring, access control, and security systems. Traditional 2D vision approaches struggle with low-light conditions, spoofing risks, and limited spatial awareness—creating challenges for reliable automation.

This white paper examines recent advancements in Indirect Time-of-Flight (iToF) technology and how high-resolution depth sensing improves performance in smart building environments. It covers system-level considerations for deploying iToF in access control, intrusion detection, and people tracking applications, while addressing challenges such as ambient light interference, motion artifacts, and system complexity. Engineers will gain insight into how modern iToF architectures enable scalable, real-time 3D sensing for intelligent building systems.
