Prioritising Privacy with Overhead ToF People Counters

In today’s world, where data collection is essential for optimising spaces and understanding visitor trends, privacy-preserving technologies have never been more crucial. Traditionally, camera-based sensors have been the preferred choice for advanced people counting, but overhead time-of-flight (ToF) counters are rapidly emerging as a superior alternative. These sensors deliver robust data collection while significantly enhancing privacy and security.

Although camera-based systems offer high accuracy and detailed analytics, they often raise concerns about individual surveillance. This can create discomfort among visitors and pose challenges in complying with privacy regulations such as GDPR.

Unlike cameras, our Overhead ToF People Counters operate on a fundamentally different principle. Instead of capturing visual images, they use near-infrared light reflection to produce low-resolution “heat maps.” This allows them to detect the presence and movement of individuals without recording identifiable features or personal details.

Discreetly installed in the ceiling and facing downward, our Overhead ToF People Counters precisely measure visitor traffic, maintaining high accuracy even in medium-traffic environments. Beyond basic in/out footfall counting, they also provide advanced analytics, such as differentiating between adults and children based on height, counting groups, and identifying staff members via unique lanyards.
We offer two sensor models: one with Power over Ethernet (PoE+) for combined data connectivity and power through a single cable, and another with integrated 4G connectivity for easy deployment without the need for network cabling.

When integrated with the EvolvePlus Cloud Dashboard, data from the people counters transforms into valuable insights, highlighting peak visitor times and occupancy levels across various settings, including retail stores, shopping centres, libraries, galleries, museums, offices, and commercial buildings.
