Why deploy occupancy sensors in UAE CRE?
Occupancy sensors detect the presence or number of people in a space and enable energy optimization, space-efficiency decisions, health and safety monitoring, and retail insights for tenant spaces and malls.
- Energy optimization (HVAC, lighting).
- Space-efficiency decisions (desk/meeting room usage).
- Health and safety (crowd density monitoring).
- Retail insights for tenant spaces and malls.
In the UAE climate and commercial environment, optimized HVAC control delivers significant cost savings; retail operators and large tenants can use occupancy data to improve customer flow and staffing.
Types of sensors and trade-offs
Choose sensors based on accuracy, privacy, range, and cost.
- Passive Infrared (PIR): Low cost, detects motion and presence; limited for still occupants.
- Ultrasonic: Good coverage for small rooms; can be sensitive to airflow.
- Radar (mmWave): Long-range, accurate even in low-light; preserves privacy better than cameras.
- Thermal: Counts heat signatures; useful for people counting while maintaining anonymity.
- Camera-based analytics: High accuracy and detailed behavioral insights; requires careful privacy controls.
- Wi-Fi/Bluetooth device counting: Uses probe data from phones; passive but biased by device carriage rates.
- CO2 sensors: Indirectly estimate occupancy via air quality; better for ventilation control than precise counts.
Combine sensor types where necessary, for example radar for open-plan areas, thermal for meeting rooms, and CO2 for ventilation zones.
