How to choose Sensors

6° beam radar sensors track vehicles in a single lane at up to 400 meters.

Available with or without traffic statistics capabilities.

Stalker 6x26 degree Stationary Speed Sensor

Stalker Radar’s new Stationary Speed Sensor II’s narrow, lane-specific 6° beam accurately detects and tracks vehicles in a single lane at greater distances than other wider beam radars.

Monitors up to 10 vehicles

The Speed Sensor II is capable of monitoring up to 10 vehicles in a single lane at distances of up to 400 meters, and provides OEMs and system integrators with a sensor solution from a proven leader in the radar speed measurement field.

Plus, the Speed Sensor II’s open-frame configuration provides the design engineer with a number of physical installation options, while its digital signal processing manages tracking vehicles either moving toward or away from the radar.

The Speed Sensor II’s small size and light weight, plus broad operating temperature and low power consumption, make it a versatile and adaptable choice for a range of environments and applications. Its target recognition/filtering settings make it adaptable to any type vehicle or road condition.

On-board traffic statistics

If traffic analysis is required, a narrow-beam sensor with on-board traffic statistics capability – the OEM 6° x 26° Traffic Statistics Sensor – coupled with Stalker’s easy-to-use, full-featured Traffic Statistics App is the comprehensive solution.

Comprehensive traffic statistics collection and analysis

Easy-to-use, full-featured traffic analysis application, The Traffic Statistics Sensor collects and stores raw data in embedded non-volatile memory until accessed by the Traffic Statistics App. The data is then presented in an intuitive graphing window that includes the mean, 85th percentile, and 10 mph pace. In addition, Count vs. Time, Speed vs. Time, and Count vs. Speed can be displayed and analyzed. The application also controls radar sensor setup, survey data extraction, survey data analysis, and report creation, while working seamlessly with the Stalker Traffic Statistics Sensor.

Data can also be exported for further use in Microsoft Excel. The Stalker Traffic Statistics App is compatible with 32- or 64-bit Microsoft Windows XP, Windows Vista, Windows 7, and Windows 8 operating systems.
