Beyond Traditional Infrared Tailgating Detection

Traditional infrared and optical sensors are widely used in turnstiles and access control systems to detect passage events and beam interruptions. HYD 3D sensing adds spatial intelligence to understand what is moving through the passage and where it is located, enabling more precise tailgating detection and access behavior analysis.

Traditional IR / Optical Detection

• Detects beam interruption or presence
• Indicates whether a target passes the detection area
• Limited target classification
• Limited spatial position information

HYD 3D Spatial Sensing

• Distinguishes people and objects
• Understands movement through the access lane
• Provides precise spatial position information
• Supports advanced tailgating and passage behavior detection
