Title: The Man vs. Machine: Who is Winning?
For many, speeding is a normal part of daily life. In fact, speeding is so common that there are electronics available to help drivers get away with it.

How Does it Work?
The radar speed gun was invented by Bryce K. Brown of Decatur Electronics in March 1954 and was first used in Chicago, Illinois in April 1954. Patrolman Leonard Baldy was the first officer to issue a speeding ticket using a radar gun. Radar uses radio waves to detect distance and speed of objects based on the doppler effect. A transmitter oscillates an electrical current through an antenna to an amplifier by using a radio wave. Objects in the path of the radio wave will be bounced back through the antenna to the speed gun receiver.
Laws About Detectors
Lidar (a newer speed detector that uses light instead of radio waves)
The basic element for a lidar gun is concentrated light. Lidar guns clock the time it takes for a burst of infrared light to reach an object and return to its starting point. This time is multiplied by the speed of light to determine distance from the object. The lidar sends many quick laser bursts to collect multiple distances in less than a second. The system compares the distance samples to determine speed.
In many cases, the lidar system is completely automated. When a speeding car is detected the system triggers a small camera. A picture of the license plate and driver's face is taken. The central office simply issues a ticket and mails it to the speeder.
Lidar is more difficult to evade than traditional radar. Laser beams are more focused and a car is likely in the beam's sight before a detector recognizes the lidar. Speeders can adapt by reducing the reflectivity of their car (e.g. using flat black paint and/or special license plate covers) or using laser jammers. The laser jamming detectors detector has light emitting diodes (LEDs). They produce their own light beam so the lidar can't recognize any reflected light and can't get a clear reading. Of course, no detector is 100% effective.
The Spectre Elite: 1-Up for Police
Police officers use the Spectre ELITE to detect hundreds of radar detector models. All radar detectors operate in the same way including those that feature "cloaking" or "Spectre Alert." The Spectre ELITE detects electromagnetic "leakage" from the local oscillator, a component common to every radar detector. Manufacturers try to evade detection by suppressing local oscillator leakage with shielding, trying to adjust the leakage to an undetectable frequency, turning off the local oscillator when detecting a Spectre.
The ELITE can usually detect "stealthy" detectors before they can detect the ELITE. The Spectre ELITE is sensitive and adaptable, detecting many detectors at nearly 1,000 ft away. They have excellent target identification from leaky detectors, can distinguish among multiple signals, and can "scan" traffic for commercial vehicle offenders. It is windshield mounted and can rotate 360 degrees to detect at all angles.
