Speed ??control. Errors radar.

Speed ??of vehicles members of the State Inspectorate for Road Safety was measured as the stationary posts, as well as in other parts of streets and roads. Stationary positions may be equipped with remote video cameras that transmit images to a monitor. When it detects excess of established speed on the screen is fixed car-breaker with a clearly visible license plate, and the date and time of violation. Usually, this technique works without fail, giving objective data. To control the speed of movement is now also widely used remote measuring speed of vehicles such as "Barrier-2M (SOFSF-1OOSTSM). He is able to determine the speed of movement as a single car and a car moving in a group of vehicles with the greatest speed. If you are sure not to exceed the permitted speed and the meter indicates the excess, please indicate this in the protocol. Speedometer retains its characteristics at temperature from minus 30 to plus 50 degrees, relative humidity of 90%, with an air temperature of plus 30 degrees and atmospheric pressure 60 to 106,7 kPa. Therefore, if the device is using lies (or lay before using) on ??the hot hood of the car, then you may receive incorrect results. Distortion of the actual speeds is also possible as a result of interference sources which may include: - transportation, moving on a lane of oncoming traffic in relation to the measured direction - fixed industrial installations, with moving parts - Fluorescent advertisements and fluorescent lights - running radio, radio receiving lines of communication, radar and other high-emitting radio devices - the faulty network onboard a car - Various sources of electric and magnetic fields, such as: high voltage power lines, lightning, etc.; - vibration support, which is set measuring block. If the zone of the meter at the same time your car hits another, moving faster on more than 10 km / h, the meter automatically switches to measure its speed. Instruments such as "Barrier-2M record time from the moment of exceeding the threshold speed for 10.5 minutes (plus or minus half a minute). Therefore, without wasting any time after the stop, control that the device has fixed speed is your car. If the specified time, the device is not fixed, but the traffic police claims that have already reset the timer, be sure to note this in the protocol.
