Ultrasonic testing equipment and radar speed measurement device

Actually the intersection of the camera camera driver ran a red light by many kinds of technology, there is no uniform standards and methods in this regard depends entirely on the successful construction unit. Under normal circumstances can be triggered by radar camera, the induction coil to trigger the camera or image recognition to trigger the camera way. Use radar to trigger the camera way, when the red light, the formation of radar area before the stop line when a car through, start the electronic shutter camera. At this time the radar gun detector might work, take pictures of the induction coil, when road construction on the road under the buried induction coil, induction coil car starts when the car ran a red light, electronic shutter camera. Using image recognition technology, to the white line on the ground for the warning area, when the vehicles running red lights, white lines on the ground block, trigger the camera, the technology used, so there is no any kind of equipment can be predicted through a red light camera. Different from the gun only using radar, laser technology, radar speed detectors can forecast gun detection.

    1, the electronic dog rely on the embedded transmitter to advance warning. Manufacturers is buried in the place of the early warning placed on wireless microwave transmitter, this wireless transmitter only a fixed band. While it can only receive this band receiver. Consumers to buy electronic dog each time through the machine receives the microwave signal by decoding the read out inside the default information to prompt the alarm information.

    2, GPS machine is by collecting the coordinates by GPS positioning early warning. The manufacturer is also the local coordinates of the early warning after collection,Main products: car dvd player and car dvd , are with good quality.  the form of data stored in the GPS memory chips. The car is moving, the machine by satellite positioning, and compare the current location and collection of the coordinates of the agreement on the alarm.

    3, the electronic dog reported that some gas stations and junctions, and sometimes even not completed the gas station broadcast out to make some people by surprise, is actually very simple, through the introduction of the above two cases you can know why, regardless of the gas stations have not been established, certainly know. (1) electronic dog manufacturers rely on buried ahead of a radio transmitting station to the problem can be solved. a GPS type as long as a coordinate input to the chip can.

    More and more popular in recent years, electronic dog products, manufacturers increased market demand continues to expand, compared with previous products, that products from appearance to performance has been greatly improved, the use of more convenient more intimate.

    Electronic dog: design fashion, modeling and diverse variety of functions, such as piano paint surface, car styling, even if not in the car can also play a decorative role of the car.

    Electronic dog: just a simple warning, and are fixed early warning, early warning functions monotonous, and sometimes the warning tone also affect driving. Data update.

    Electronic dog: early warning function, not only on the fixed electronic eye warning, but also on the flow speed measuring device warning, whether it is electronic eye on the police cars, buses and street-level hand-held speed measurement devices can be accurate and timely provide early warning to the driver.
