A radar detector is a small device that is mounted on the dashboard of a vehicle. Its purpose is to alert the driver to the presence of any police speed traps within the area. This allows the driver time to slow down before reaching the speed trap.

A Photo radar is an automated system with a radar gun tied to a camera. It came originally from Germany where it is called MultiNova. Presently, photoradar systems used in New Zealand use either Ka band at 34.6 GHz. The radar guns are angled across the highway between 20-22s? degrees. These photoradar guns have a very low output power from 2.5 mW and below. Due to the low output power of the photoradar guns, most radar detectors will give no advanced warning.

Photo radar is generally an unmanned device that identifies speeding vehicles using radar, and then takes a photo of the vehicle including the license plate. The violator later receives a ticket in the mail. Although photo radar is only used in a very few areas of the US, it is very common in some other countries overseas. Sometimes photo radar is weak, and aimed across the road so it is difficult to detect. See similar questions...

Shopping for a radar detector can be confusing, as there are a lot of different units available with different features. Really, it all depends on what you want out of a detector. Here are some suggestions: If you are a lead foot, performance is king. The best radar detector for you will be one of the top models on the market. See similar questions...

Yes. Radar detectors are legal, except in commercial vehicles with gross vehicle weight ratings of 10,000 pounds or more. See similar questions...

There are a few systems which do not work on radar or laser and therefore radar detectors cannot detect. They don’t detect VASCAR (being followed and videoed by an unmarked police car) and the SPECS SVDD and Truvelo systems. The GPS detectors alert you to these systems when they are in fixed locations.

Just press the button on the dock so that the USB device gets detected by the system and that gphoto2 software can detect it. See similar questions...

Radar helps you see what's around you. An antenna mounted high above your boat (often on the mast of a sailing vessel) sends radar waves down towards the ground, hoping to pick up reflections of land or other boats below. It's not foolproof - it can often pick up images of waves instead of real objects - but it definitely helps you see what's around you, especially in conditions of poor visibility.

There are two places that you can tap into power- Either the universal transmitter power in the roof center console or the cell phone power. Below is an example of one of each. See similar questions...

A VASCAR stands for Visual Average Speed Computer And Recorder and is a timing device that times your vehicle from one predetermined point to another. It is like a stop watch and puts out no signal. No radar detector can warn you of VASCAR. VASCAR is commonly used in Pennsylvania as local law enforcement departments can not use radar guns by state law. A Radar travels at the speed of light which is 186,000 miles per second. See similar questions...

Long range radar detection. Simply put, a detector really has only one single mission: to provide enough advanced warning of radar and laser signals to allow you to check your speed and react appropriately. Long range detection relates directly to sensitivity: the greater the detection range, the more protection a detector delivers. Detecting X and K band radar at long range is easy compared to Ka band radar, and most detectors today do it reasonably well. But here's the problem. See similar questions...

There are some decent detectors under $200, the new Cobra XRS-9730 is a great value. Until the new Cobra models were released only the Beltronics RX65 supported the new KU Band that is currently used in Europe and is coming to the US shortly. For $129.95 this detector has very good range and it supports all the current technology including the new KU Band. See similar questions...

In our opinion we feel that a corded radar detector will offer you the best protection. One of the biggest problems with a cordless radar detector is that in order to conserve battery power these units power on and off constantly. Because of this cordless radar detectors have less range and they also do not offer protection from POP radar. See similar questions...

The range of a radar detector is depending upon quality of 500m-200m. Such surroundings as curves, dome-shaped mountain tops, bridges etc. can slightly affect here. See similar questions...

There are many reasons why your radar detector may not have detected the radar. One simple reason is that your device is not set up to detect the specific band or type of device the officer was using. For example, a radar detector will not tell you if the officer is using a stopwatch or LIDAR to check you speed. See similar questions...

Radar detectors give audible warnings for police radars, but often too late for you to adjust your speed. A radar scrambler disables the radar/lidar detector, giving you time to slow down if necessary. See similar questions...
