DragonEye Defender

Fixed Installation Automated Speed Enforcement

Automated Speed Enforcement is proven to reduce accidents and save lives.  However, the integrity and success of any automated traffic enforcement program rests on the foundation of the core technology deployed at the roadside.  Law enforcement agencies and citizens must have absolute confidence that vehicle speed measurements are accurate and the actual violating vehicle is correctly identified.  The DragonEye Defender is designed to give you that confidence.  Read further to find out why.

Laser Precision Measurement

DragonEye's Defender system uses a proprietary, advanced version of our field proven LIDAR speed measurement technology.   The Defender delivers 600+ precise laser measurements PER SECOND, PER VEHICLE, to provide enforcement grade speed measurement accuracy.   The Defender system positively indicates the measurement vehicle with dedicated laser precision. One laser for each lane; just as with your proven handheld LIDAR technology.  With the Defender, there are no multi-reflection radar signals or broken LED beam data to parse through in order to determine which vehicle may have been measured.

With a dedicated high-resolution camera for each and every lane of traffic, the Defender can accurately capture speeding vehicles at a rate of 3 per second in each lane, simultaneously.

Backed by Proven Expert Witness Testimony

Ultimately every Automated Enforcement system will be challenged in court.  Was the speed measured correctly?  Can you prove you measured the speed of my car and not the one just in front of me?

DragonEye Technology engineers have expert witness, court testimony experience in Frye and Daubert hearings over the past 20 years, successfully defending LIDAR speed measurement and automated enforcement systems.  Make sure your Automated Speed Enforcement provider is ready and prepared to stand behind their systems!
