Your need for a police radar detector for car depends on what kind of driver you are. If you are a law-abiding driver that is never in a hurry and does not get impatient with other drivers, then you don’t need this device. The chances of getting caught for over speeding is very slight.

What you should think about is a police officer giving you a speeding ticket by mistake. You might think that it is impossible, but it happens many times to many drivers at certain blind spot. This is one good reason why you need a good radar detector.

Most of the times over speeding takes place in the city. You might commit it unintentionally. There are lots of drivers who were not able to realize that they are committing such violation.

How does A radar detector works?

A radar detector is a radio transmitter and receiver in one unit. It is a device that oscillates an electrical current to increase and lower the voltage at a specific frequency. The electricity produces electromagnetic energy.

Once the current oscillates, the energy passes through the air as an electromagnetic wave. The transmitter has an amplifier that increases the electromagnetic energy intensity, and the antenna broadcast it in the air.

The radio receiver is the reverse of the radio transmitter. The antenna picks up the electromagnetic waves and transforms them into an electrical current.

The radar with its radio waves detects and monitor different objects. It can tell you how far are you from the object. The device transmits a radio wave and checks if there is an echo.

In case there is an object within the radio wave, it displays the electromagnetic energy, and the radio wave bounces back to the device.

The radio waves move into the air at a speed of light, to help the device calculate the distance of the object based on how long it will take for the radio signal to return.

The radar is used to measure the object’s speed due to a Doppler shift. Radio waves have a certain frequency.

When the car and the radar are not moving, the echo will get the same wave frequency as the original signal. Once it reaches the car, each part of the signal is shown, showing the original signal.

But once the car moves, each part of the radio signal is reflected at various points in space, thus changing the wave pattern.

A second segment of the signal will travel into a greater distance when the car moves away from the radar guns. The effect is known as moving out of the wave or reducing its frequency.

On the other hand, if the car moves toward the radar guns, the second segment travels on a shorter distance as compared to the first segment. Because of this, the valleys and peaks of the wave get squeezed together, and the frequency increases.

The radar detector can calculate the speed of the car based on the frequency changes.

Buying Guide

If you are looking for radar detector that is reliable and effective, here are a few tips you can consider when choosing or comparing radar detectors.

Even if the drivers are not driving over the speed limit; if they see a police car around, they feel anxious. It is best to have a good dash cam radar detector.

1) Cost and Performance

The first thing you need to figure out before buying a radar detector is if it is worth to buy radar detector for.

Determine if the device performance is worth it. There are lots of good detectors that are available at different price points.

Just like other electronics, you get what you pay for. A good system feature technology like a super long range or band selection that cost more than the ordinary detectors. 

So, determine your budget and choose the best detector that is worth buying for.

2) The Device Should Avoid False Alarms

Most of the detectors have the same qualities. It is best to choose the one that helps you know who is on the road ahead of you. You also need a detector that repeatedly activates due to false positives. You want an undetectable detector.

3) Offers Detector Protection

Using radar detectors on areas like Washington and Virginia is prohibited. If you were caught in these states, you would be penalized.

Police can catch you through Radar Detector-Detector devices. They can identify and track you down with the use of a detector.

Good thing some detectors are undetectable and keeps you protected. Thus, it is important to consider a device with detector protection.

4) Reliable - Eliminate False Alarms

Radar detectors are very sensitive, and users are aware of this. An automatic grocery store doors can set off your detector. If you are passing thru several automated doors, this could be annoying. A detector that turns off constantly defeats the purpose of having a detector.

Choose a radar detector that eliminates false alarms. It should not turn on or off easily as you don’t know when those type of signals will come.

The best radar detectors have target counters so you will know how many alerts they can get. Although this does not get rid of the false alarm, the fact that you can still detect if a police radar is in the parking lot, it is still very helpful.

5) Wide Range of Frequencies

It is best to choose a radar detector with a longer range. Range pertains to the distance a detector can detect a possible radar threat. The farther it can detect the radar, the greater the range.

Your detector should be able to detect cop ahead before he can measure your speed. So if you have an old detector, you have to replace them with a modern device that can detect longer range.

6) GPS

This may not be as important as the other features, but if you have some budget for a device with GPS, then we would suggest that you get one.

What makes this feature very helpful? One is that detector with GPS has a built-in camera locations database that you can update the list of locations with red light and speed cameras.

GPS can mark false alert locations. A device can block the location and the band. If you pass this route regularly, this can cut down the noise. This feature can lower sensitivity or muted when you are driving slowly.

7) Display

Some radar detectors have large, multicolored, fancy screens. Although these are nice and easy to look at, we don't think the display is as vital as the other features.

 Keep in mind you are driving. You should be focusing on the road, not on the detector. Visibility and how it handles glare what matters.

FAQs – Frequently Asked Questions

1. I just passed a cop car, but my radar detector didn’t go off, is it defective or not? 

There are several reasons why your radar detector did not go off even when there are cops around.

Maybe, the police car you just passed might not have a radar gun in their vehicle, or they are not transmitting and clocking cars. 

If this is the case, there is nothing that your radar detector can detect and therefore it will remain silent.

2. Why My Radar Detector Goes Off Sometimes Even When There Is No Police In The Area??

Some things can trigger a radar detector and not just the police radar guns.

Some of which includes door openers in a grocery store, car, and semis with new collision avoidance systems, "your speed is" signs and even cars and semis with collision avoidance systems. 

These collision systems are very helpful that usually operate on K band and are becoming very common and can be hard to filter out.

3. Is it Legal to Use a radar detector?

As mentioned earlier, it is not legal to use the detector on Virginia and Washington DC. If you get caught, they will confiscate your device, and a speeding ticket will be issued.

However, some say that the law is more relaxed nowadays, and they do not do that anymore.

They write down your RD's serial number. The device is also not allowed on military bases or in commercial trucks above 10,000 pounds.

4. Does radar detector work on police using a laser? 

TNo. You will not get any advanced alerts if the police are using laser guns. Your detector may go off, but it is a bit late as the police already have your speed.

For this kind of situation, you need a laser jammer. So it is best to get a detector and pair it with a laser jammer. 

5. Will a radar detector always help a driver avoid speeding tickets? 

Absolutely not. The device is designed to help lean the odds in your favor but not to make you invincible. Even if you buy the most expensive and advanced device, you can still get tickets.

In some cities, it is not allowed to use this device. So you might get a speeding ticket if you happen to go to the cities like Virginia and Washington.
