Thermal activity sensor chosen for smart buildings project

The global market for IR sensors in smart homes and buildings is expected to grow from $694m in 2016 to $1,068m in 2022. Both ULIS and Irlynx manufacture thermal vision products to meet emerging needs in workspace management, energy management, security and safety. ULIS claims to be the only manufacturer to produce, in mass volume, advanced occupancy sensors that give system integrators the flexibility to modify key parameters within the thermal sensor to match system requirements.

"ULIS is pleased to enable deployment and testing of a people counting solution using its newly designed Thermal Activity Sensor,” said Hien Pham Gia, Sales and Marketing Director at ULIS. “Irlynx has provided ULIS with additional opportunities to obtain valuable end-user feedback based on real-life experiences. This will allow us to confirm the key benefits of our sensor, as well as further strengthen its value proposition for facility managers.”

Irlynx developed the electronics as well as the algorithm for the TAS to perform thermal video data analysis and to activate the people counting function. Irlynx’s task was made easier since in using ULIS’ sensors the algorithm could access raw data directly from the sensor. This eliminated the need for Irlynx to carry out complex calibrations.

“Irlynx was looking for a partner with great technology and a good understanding of our markets, where cost is key. ULIS demonstrated that it could adapt its offer and address this challenge. Its technology allows us to deliver an unmatched value proposition to the smart building market, with a greater performance/price ratio than any existing people counting solution,” said Guillaume Crozet, Vice President sales and marketing at Irlynx. “We also deliver advanced human activity data such as people’s position and trajectories, and desk occupancy, increasingly of great interest among our customers.”

Advantages of ULIS’ space occupancy sensor
One key advantage a thermal sensor offers facility managers is that it comes without facial recognition, an important feature to preserve the anonymity and privacy of subjects, for example, when monitoring a building. Furthermore, compared to other thermal technologies, ULIS’ TAS offers a wider field of view up to 120°, meaning that fewer devices are required to cover large surface areas.

Customers have several options available for tuning ULIS’ TAS for specific application requirements. One option is to work directly on raw video data (true 14 bits parallel bus), which is easily interoperable with standard microcontrollers and low-cost FPGA. System integrators can also optimise the sensor’s power consumption and use it with a standard battery lasting three or more years.

TAS offers the market a wide range of advanced functions beyond the detection function offered by lower resolution sensor alternatives. It can support numerous applications: 

• People counting
• Localisation and people tracking
• Activity and posture classification 
• True intrusion detection (reducing the number of false alarms) 
• Real presence detection (distinguishing people from animals)
• Hot spot and fire detection.
