Stalker Stationary Speed Sensor

When measuring speed from a fixed position, the Stationary Speed Sensor  (radar) is the right choice. The Speed Sensor’s waterproof case allows it to be mounted in any outdoor location. Use it anywhere that speed measurement from a fixed location is the primary requirement.
