An AI-Enabled People Counter

The advanced people counter excels in bi-directional tracking, offering real-time and reliable data with an extensive detection range. It maintains high accuracy through its sophisticated AI algorithm, which effectively filters out side-by-side and U-turn walkers.

Flexible Wireless and Stable Wired Versions

Battery Version

For wire-free installation, choose the battery version, which leverages both thermopile and radar technologies. Enjoy a completely wireless setup, eliminating extensive wiring or infrastructure modifications.

Type-C Version

For extended use, the Type-C version is ideal. Using thermopile technology, it connects directly to a power source, ensuring continuous operation without battery concerns.

High Accuracy of up to 95%

It ensures reliable and precise data collection with an accuracy of 95%. When counting single-person passages exclusively, the wireless people counter achieves an exceptional accuracy rate of up to 99%. This level of precision allows you to rely on the collected data for critical decision-making confidently.

* Tested under conditions of being installed at a height of 2.7m and in an ambient temperature of approximately 25°C.
* Tested with targets averaging 1.7m in height. In real customer situations, accuracy can be affected by device installation height and the average height of the targets.
* It is recommended that the device be installed 70-120 cm from the target, with the target's average height being considered.

Multiple Sensors in One, One for More

Experience cutting-edge precision with multi-sensor fusion. Utilizing radar to activate, the people counter delivers unparalleled accuracy with an advanced thermopile sensor. Simultaneously, a dedicated temperature sensor ensures the device performs flawlessly within ideal environmental conditions.

Ultra Low Power Consumption

To reduce power consumption during unoccupied nights, users can set sleep periods where the device enters hibernate mode. When the active period begins, the device resumes full operation. The synchronized operation of the radar and thermopile ensures energy efficiency and low power consumption, making it a ESG compliant people counter.

100% Anonymous Detection

It is compliant with GDPR. The thermopile and radar technology will not collect any personally identifiable information while the LoRaWAN® narrow bandwidth only transmits data, which 100% guarantees privacy protection at source.

Milesight D2D Communication

The exclusive Milesight LoRa®-based protocol allows the people counter to easily communicate with other Milesight LoRaWAN® devices without network infrastructures. The facilities like lights can be intelligently switched through the linkage to realize accurate, timely, and automatic responses, saving energy for management staff.

High Data Integrity with Storage and Retransmission

The people counter can store up to 1000 historical data records with time stamps. When the connection fails, it will continue to collect and store environment data. Once reconnected, the data collected during that period will be retransmitted to the gateway, thus avoiding data loss.

Snap-Together Installation

Enjoy a user-friendly snap-together installation experience reminiscent of a jigsaw puzzle. This intuitive assembly process ensures a straightforward and hassle-free setup, making it accessible for everyone.
