What Does a Radar Detector Do

Different areas of the world employ various means of detecting overspeeding cars. However, in more advanced methods to discover the speed of vehicles. They use handheld devices that are often mistaken as pistols for those who are unaware. These devices are called radar detectors.

In this article, we will answer the common question, “What does a radar detector do?”Aside from giving you a background about what these devices do, we will also delve more in-depth as to how radar detectors work. So without further ado, let’s start.

What is a Radar Detector?

Radar detectors are small pieces of equipment that detect the presence of radars. These devices help authorities such as policemen determine cars that drive over the intended speed limit. Various radar detectors are also able to detect laser speed guns. These devices counteract the capabilities of other radar detectors to veer away from speed traps. Now that we already discussed what radar detectors are let us now consider how these devices function.

How Do Radar Detectors Work?

Radar Detectors emit radio frequencies which are undetectable to the naked eye because they travel at the speed of light. These radio waves then bounce back to the device whenever an object interferes and passes over its path. The radar detector then analyzes the time and duration at which the radio waves collide and encounter with the moving purpose as well as the time it took to bounce back to the detector. The device then converts the factors mentioned above and presents it as the speed and distance from the moving object.

Whenever a car is moving towards and colliding with the radio waves emitted by the radio detector, the frequency and time at which the radio waves bounce back will now be altered. If the car is moving closer to where the radio waves were emitted, the return signal will then have a smaller distance, thus, increasing the radio wave frequency. The change in radio wave frequency can then be used to analyze the speed of the moving car.

Radar detectors also perceive similar devices by detecting the radio waves the appliance gives off. To put it, radio detectors are just radio receivers which can sense various frequencies emitted by radar devices. Most consumers buy radar detectors to be notified whenever police or authorities that use similar tools are nearby.

Police officers that detect speeding cars are situated on a particular location. Because their radar devices aim to detect specific vehicles or objects that pass by, radar detectors from moving vehicles can identify them right before they pass through the police or authorities. With this at hand, they can determine if the police car is nearby.

Some, highly advanced radar detectors are even able to confuse the radar detectors of police officers. With this, the radio wave or signal that bounces back to their devices are already scrambled or broken. This principle is otherwise known as signal jamming. In this principle, the radar detectors that receive radio waves from similar devices jumble and disrupts the signal as they bounce back to the emitting radar device. As a result, the disrupted radio signals that reach the police confuse the device and gives off an inaccurate reading of the speed and distance.

In addition to the different types of radar detectors mentioned above, there are also sub-categories that group them according to the level of frequency they emit. The X band detector emits low frequencies amidst a high output. With this type of sensor, the device can detect signals as far as 2 to 4 miles. Most police forces use these types of radar detectors. The caveat with this type of radar detector is that it is not accurate. It can even detect signals from garage door openers.

K band radar detectors emit lesser wavelengths. These types of radar detectors can determine signals from .5 to 2 miles. With this, it is more challenging to detect overspeeding cars using this type of radar detector.

Buying a Radar Detector

Most people expect radar detectors to be costly, however, the reality is they aren’t. The disadvantage is you cannot buy them in a local shop or the mall. The easiest way to buy a radar detector is to purchase it online. When choosing a radar detector, you should take into consideration, some factors. Moreover, you should check whether the police department from your area allows such devices or not.

When buying a radar detector, you should avoid used or old units. You should always buy one that comes with a warranty. Purchase one that comes from a reputable company. Considering that you purchased your radar detector online, you should also check the location of the seller. This is important since shipping fees will become higher when you buy one from sellers outside the US.

Several radar detectors can be bought at $100. However, these units are not highly recommended because they usually come with poor quality and low durability. Moreover, these units tend to be inaccurate when it comes to reading radio signals. If you want a reliable and efficient radar detector, you should prepare to shell out at least $400. One of the most popular radar detectors in the market now is Valentine One. The device is well received by both reviewers and consumers across the globe and boasts of a high-quality build form.

Radar detectors should be bought with a license. Some consumers purchase radar detectors to avoid authority. These units are often illegal and unlicensed. These devices are used to jam radio signals emitted by radar detectors used by the police or administration.

However, most police departments can pick up on these illegal devices and equip themselves with better, more advanced detectors. So while there is a possibility of dodging an overspeeding ticket, the chances are slim, because of the more sophisticated radar detectors. Moreover, authorities employ other means of detecting over speeding vehicles aside from the use of radar detectors. With this, the best way to avoid an over speeding ticket is still, to follow the rules and speed limits imposed on your area.
