People Tracking & Market Needs

People Tracking mmWave Radar

mmWaver radar technology derived from automotive radars for auto pilot. Radar signal sent out and bounced back when hitting obstacles. Speed, position, angle and size of the multiple obstacles are measured.

the recent commercial use for people tracking limits the RF power down to 1/1000 and scan range down to 20m with the below advantages

- response to human body motion only. static background eliminated

- exact positions and tracks- hidden installation- large coverage with multiple radars

Commercial Market Needs

replace human, increase productivity, study customer behavior

The widely adoption of the anti-wandering systems (防遊走) significantly bring down the cost of facial cameras. Marketers start realizing the potential need of customer behavior study by automatic machines with accurate engineering data.

The conversional facial cameras offer :offline visitor count report for marketing analysisactive visitor count for crowd control

Marketers and enterprises need more :people tracking and customer behaviour studystaff tracking and KPI managementface recognition + customer tracking for long-term behaviour study

Customer’s problems
