How to choose Sensors

Narrow horizontal beam sensor ideal for
lane discrimination

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

A narrow 6° beam, adjustments for mounting angle, and open-frame design allows flexible mounting options for OEM developers integrating it into their systems.

The Speed Sensor II utilizes digital signal processing that enables it to track vehicles either moving toward it, away from it, or both directions simultaneously. Additionally, it has target recognition/filtering settings and a speed alarm output.

Including all the features of the OEM 6x26° Stationary Speed Sensor II, the OEM 6x26° Traffic Statistics Sensor adds the capability to store traffic volume, speeds, direction, and classification in the unit. The Stalker Traffic Analyst application is available to review, analyze, and present the traffic data.

RS-485 connection allows for multiple sensors to one controller.

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.

Stalker 6° x 26° sensors tracks in a single lane up to 400 meters

Comprehensive traffic statistics collection and analysis

Using captured data from the Stalker Traffic Statistics Sensor, updated analysis control allows you to take raw data and display it by count vs time, count vs speed, and 85th percentile, just to name a few. Data can be split, graphed, filtered, and then rendered in a color report designed with Agency branding and support information.

Beginning with the setup, the actual sensor can be configured. Then, the intuitive survey management tools walk the user through calendar setup, location details, speed and time resolutions, vehicle classification, speeds, distances, and more.
