Perhaps we all have some experience with speed measurement. Whether measured and the police in safety vest stopped us directly, and we just saw the car standing somewhere radar. Or we go to places where the operation of section speed measurement. Some people agree with measurements, but a lot of people perceive that the speed is usually measured just make it as easy chosen as much money, not make it good for safety.

 

That suggests the number of unmarked cars that exist for "covert surveillance", but this supervision is usually only measure the speed, nothing else. While on the roads every day we see things that are dangerous or annoying more than speeding. However, aggressive and reckless drivers who while the speed limit rarely exceeds we see on the roads every day enough.

Second laser speedometers

Laser meter, a device based on the issue and return receipt beam of electromagnetic waves with wavelengths in the near infrared region of the spectrum, the Czech police used to measure the increasing use since 2008. The use of laser measuring municipal and state police, but each has a slightly different device. Their range is about 1000 meters, but they can reliably take the photo roughly 200 meters.

 

Some laser meters are also able to recognize that he was disturbed by jet, and you cop the display message. In contrast, some jammers are able to interfere with the laser beam so that it did not recognize the device. All of these meters in the service of the state police are portable, sometimes standing on tripods, sometimes holding a policeman in the hand. There are many reportedly estimated around 100, which would soon be interchanged within the purchase of 103 new "pistol”.

 

Municipal police forces also used in addition to Truce meter Polaner III, which operate on the same principle of the laser beam, just a little different look. Work by a policeman in the viewfinder will choose a vehicle that wants to measure, aims mostly at the license plate because it is metal and straight, and pull the trigger. The instrument sends laser beam that bounces back and calculated according to the measured speed of the vehicle.

 

Previously, it was approved up to 100 m; today it is permissible to measure up to 400 m. At a distance of a man police hardly notice, even if he was wearing a reflective vest. Modern laser meter, for example. Truman said; also have a video mode that is used for documenting offenses other than the measurement of speed. Not giving turn signals. Even they can work in automatic mode, thus completely unattended.
