They do this in part by intelligently learning and revising false alerts. Radar detectors that contain GPS chips offer greater accuracy and less likelihood of picking up false signals around you. Remote-mount detectors – These models are permanently installed and, generally speaking, are more aesthetically appealing. They provide excellent detection range but can be a lure for potential thieves.Ĭordless radar detectors – These models are easily detached and can be switched between vehicles more easily than their corded peers. Radar detectors are generally attached in one of three ways:Ĭorded radar detectors – These models attach to the windshield via suction cups. If you drive across state lines frequently, this might not be the best option for you unless you have every state’s laws memorized. Before you purchase a radar detector like this, do your research to make sure you aren’t going to get smacked with a traffic violation of a different variety. Some police are even equipped with their own radar detectors to track down vehicles that are using them-in reverse. It is important to note that radar detectors and laser jammers are illegal in some states. The newer and more cutting-edge radar detectors feature what is called a laser jammer-as their name implies, these devices not only detect the radar gun's laser beam, but jam it as well. Standard radar detectors cannot combat these laser guns. These laser guns are precise and target one vehicle at a time. These days, more police officers are using the updated technology of laser guns to detect drivers over the speed limit. Once you have passed it, a separate alert will let you know that the coast is clear. As you approach the speed trap, the radar detector will alert you. Some radar detectors are extremely precise higher-end models can even indicate the location of the police officer and their radar speed gun. It accomplishes this by prioritizing radio frequencies used most often by law enforcement. This microchip ensures that you receive fewer false alerts. If you don’t want to be alerted to the fact that there is a supermarket door nearby, then the most important consideration in choosing a radar detector might be its DSP (digital signal processor). Automatic supermarket doors, the parking sensor on the car next to you, adaptive cruise control-all these technologies utilize radio waves, and some of the lower-end radar detectors will beep if they pick up even the smallest signal. These are what are called “false alerts,” and they are caused by other radio signals the radar might pick up on. If you have ever been the passenger inside a car equipped with a radar detector, you might have heard the driver complain about the incessant beeping of the device. These simple radio signals are fairly easy for radar detectors to identify. While new technologies are being introduced more and more, most police officers use the same devices that have been used for decades. These frequencies vary, but Ka-band (the frequency most popularly used by police) operates between 33-56GHz. Radar detectors are designed to detect the radio waves emitted from these police radar guns. Police radar guns utilize wave frequencies to detect how fast a vehicle is going-the faster the car is going, the longer the wavelength necessary for the radar gun to receive the echoing signal. Consider a radar detector to give you a heads up before you get caught in a speed trap. They are just a part of life if you’re a driver.Ī radar detector can help prevent you from receiving expensive speeding tickets. In a heavily trafficked world where roadway signage is confusing and speed limits can change with little to no warning, it’s no wonder it is estimated that more than $6 billion of speeding tickets are doled out each year in the United States. If your speeding violation falls close to the national average of $150, your joy ride has now become rather expensive. You glance down, and sure enough-you are driving over the speed limit. Those familiar flashing lights loom in your rearview mirror. You're singing along to your favorite tunes, letting the music take you to new and exciting destinations as you gaze down the road ahead. ![]() You’re cruising along a remote highway or country road away from traffic-and civilization.
