SensMax Pro D3 SLR Bidirectional Sensor Set
The SensMax Pro D3 Wireless People Counter is a battery-powered sensor engineered for visitor traffic monitoring across shopping centers, retail stores, and commercial venues. Designed to detect movement direction (IN/OUT), it provides accurate footfall counts and live occupancy analytics for multi-level buildings, floor transitions, elevator lobbies, and main entrance corridors up to 9 meters wide.
How It Works
The SensMax Pro D3 utilizes an advanced active triple-beam infrared array to scan passing traffic and determine movement direction with precision. Incoming (IN) and outgoing (OUT) directional counts are recorded into local internal memory. Operating completely cable-free, the sensor mounts easily onto entrance frames or walls using high-tack adhesive tape without requiring structural modifications or electrical wiring.
Key Features & Strategic Advantages
Bidirectional Infrared Detection: Uses three active IR beams to accurately differentiate between incoming and outgoing visitors for real-time occupancy calculations.
Cable-Free Wireless Deployment: Fast, non-intrusive surface mounting via double-sided adhesive without running power or data cables.
6 to 12-Month Battery Autonomy: Low-power architecture delivers 6 to 12 months of continuous operation with fast, tool-free battery replacement.
Onboard Data Security: Internal memory autonomously stores up to 25 days of hourly statistics, protecting against network disruptions.
100% Automated Telemetry: Automatically relays count data to central gateways every 20 minutes without requiring manual staff intervention.
Versatile Range Options: Compatible with gateway setups offering RF wireless communication ranges up to 900 meters.
Available Range Variants
To adapt seamlessly to any building architecture and gateway placement, the SensMax Pro D3 is available in three distinct radio coverage options:
| Model Variant | Open-Space RF Range | Indoor Wall-Penetration Range |
| SensMax Pro D3 (Standard) | 30 – 40 meters | Standard Indoor Line-of-Sight |
| SensMax Pro D3 LR (Long Range) | Up to 150 meters | Up to 50 meters |
| SensMax Pro D3 SLR (Super Long Range) | Up to 900 meters | Up to 150 meters |
Applications & Real-World Use Cases
Shopping Malls & Retail Outlets: Monitor main entrance traffic volume and measure tenant conversion rates.
Multi-Story Commercial Properties: Track floor transitions, escalator landings, and elevator bank throughput to analyze vertical crowd flow.
Public Libraries & Museums: Maintain automated attendance logs and monitor live building occupancy for safety compliance.
Corporate Office Buildings: Track movement across main lobbies and communal corridors for space utilization planning.
