What We Do

Applied Concepts, Inc., d.b.a. Stalker Radar, was founded as a small contract engineering and manufacturing firm in 1975. Since that time, we have grown to be the United State’s premier manufacturer of police radar and Lidar in the United States. More state police agencies use our speed enforcement equipment than all other radar brands combined.

Why We Do It

Lives depend on what we do.

Our Stalker Radar line of radar and Lidar speed enforcement products can help catch speeders who may cause life-threatening accidents.

Our Street Dynamics line of radar speed signs and other traffic enforcement equipment helps remind drivers to slow down in critical areas, such as school and construction zones.

Our flood sensor warns motorists about dangerous water on roadways from the moment the problem begins, freeing up your agency’s resources to assist with more important tasks during severe weather events.

Our business is focused on creating products to support safety in and around the streets that you are investing your time, energy, and lives to protect.


Because lives depend on what we do.
