Everything You Wanted To Know About Radar Detectors
Christa Kowalczyk asked:
For most of the drivers in the United States, radar detectors are common electronic devices that are widely used in the cars to determine if the speed is monitored by the police radar unit.
The interesting part is that studies claim that the vehicles using radar detectors have a reduced threat of accidents whereas the police believe that vehicles using radar detectors have a greater risk of accidents.
That it why, use off the radar detectors is illegal in some parts of the United States and most parts of Canada and other countries such as Australia. So before you want to buy a radar detector it is better to check with the legal guidelines on the use of it, that are prevailing in your state.
Lets understand how this device works. In most of the cases, the radar unit bounces a radio wave off a moving vehicle with help of a radar gun that in turn determines the speed of the vehicle. With the change in the technology, the new speed detection devices used by the radar units are based on pulsed laser light, which is commonly referred to as LIDAR, rather than using the radio waves.
Similarly the modern radar detectors have been upgraded to alert to the infrared light emitted by such LIDAR guns. But the new radar detectors are not always effective to detect the LIDAR detection. This is mostly so as the output beam produced by the LIDAR guns is
very focused.
While radar’s radio waves can expand to 85 feet across at 1000 feet from their source, LIDAR’s light beam expands to only about 6 feet making it very difficult to detect them.
And that is why most of the time, the driver is caught unaware of the beams and they commit mistakes.So many of the new age radar detectors fail, mainly while detecting the focused beams produced by the LIDAR.
They do not scramble or absorb the many or all of their products do not affect radar and laser signals in any way. And if by any chance these products do transmit any type of radar scrambling pulses, then they are completely illegal and can invite legal action against the motorist.
So actually, actively transmitting on an FCC licensed frequency without a license is a violation of FCC regulations and a felony. LIDAR jammers are legal in most states and are regulated, much like police LIDAR guns; by the FDA as Class I laser devices.
There are many companies in the manufacturing of radar detectors. The popular of them are Escort, Cobra, Whistlers etc. When buying a radar detector, ensure that you are buying a model that has been approved by the concerned authorities.
Also look for the advanced features and go in for product comparisons wherein you can read the product reviews and also check with the pricing of the radar detectors.

Cruising Highways With Number Plate Sprays
Nahshon Roberts asked:
It’s no superhero, and it doesn’t have superpowers. But it’s being touted by many as the super-answer to unfairly issued speeding and red-light tickets. If you’re a driver, and you’re disgruntled by photo enforcement, odds are you have already heard of a number plate spray named PhotoBlocker.
What Is PhotoBlocker?
PhotoBlocker is simply aerosol inside a can. It coats license plates with a sheen invisible to humans, but visible to machines. Marketed at $29.99 a can, the number plate spray promises years of road miracles - from helping you elude a red-light ticket to ensuring you are not cited for speeding violations.
The Claim
Naturally, proponents claim that the number plate spray delivers everything it promises. PhotoBlocker is said to have been tested independently by different groups, among them the Denver Police Department, the Dutch Police, Swedish TV, Australian TV, and Fox News. What can PhotoBlocker do? It deflects the light flashed by speed-detection and red-light cameras. This light, in turn, exposes the photos the cameras take, making the license plates captured in the picture unreadable.
What Users Say
Not surprisingly, drivers love number plate sprays. It’s easy to see why. PhotoBlocker is cheap, retailing at less than $30 a bottle. Additionally, this number plate spray is easy to apply. While not fool-proof, the directions are so simple it would take a special kind of simpleton to botch things up. The number plate spray may be used on as many as four plates.
Will It Get You Into Trouble?
States have yet to come up with legislation expressly banning PhotoBlocker or products of similar nature and purpose. Understandably, this leaves many drivers and consumers confused. Are number plate sprays like PhotoBlocker illegal? Is it unlawful to coat license plates with PhotoBlocker?
The confusion stems from the fact that while it is illegal in many states to cover license plates, or prevent people from clearly seeing license plates, PhotoBlocker does not exactly prevent people from viewing license plates. Number plate sprays have a thin, white gloss. This finish ensures the license plate remains visible to the human eye. At the same time, it throws back light from photo enforcement cameras.
At present, there is no explicit prohibition against number plate sprays. If you intend to use one, however, it is always a good idea to check in with your local police force for new legislations affecting drivers. Laws evolve along with political climate and changing realities. What may be lawful today may be unlawful tomorrow. It is not impossible for lawmakers to come up with statutes that specifically ban the use of number plate sprays.
If you’re considering coating your license plate with number plate spray, remember to see the product as it really is. It’s a means to avoid undeserved tickets. It shouldn’t be turned into a license to drive recklessly.

Best Radar Detectors
Al Turnet asked:
Are you looking for a radar detector and don’t want to get ripped off? I’ve compiled a list of what I consider to be the best radar detectors for each price point.
If you’re looking to spend just a little, you should check out one of the radar detectors that are available for under $200. You can’t go wrong with the Beltronics Vector 955. It is a radar/laser detector unit with voice alerts, “POP” radar detection and VG-2 immunity. At a lower price point, you have a trifecta of units that will suit your needs: the Whistler PRO-78, Whistler PRO-520, and Whistler XTR-690. Laserveil.com reviewed the PRO-78 and XTR-690 and had this to say: “Both the Whistler Pro 78 and XTR-690 are AAA home-run hitters! … It is my opinion that these new Whistler radar detectors represent two of the greatest values in radar detector ownership, today. If it is your desire to have a full-featured radar detector which provides good protection against police radar, particularly against Ka-band, and are budget minded, you need not look further than either the Pro 78 or XTR-690.”
The next class is more than $200 but less than $300. There’s a nice selection of radar detectors available in this price range. The Beltronics Vector 965 and Beltronics Vector 995 radar detector units are both exceptional units that will serve you well. However, if you want to take the next step I recommend you purchase the Escort Passport 8500 X50 (Red) Radar Detector. It’s exactly the same as the Blue model, but is just under $300. Upon its initial release, it was “hailed as the most revolutionary radar/laser detector ever”. Escort radar detectors regularly receive very high marks amongst reviewers and they are one of the top brands available.
Finally, the over $300 class. The Passport 9500i (Red) is a top of the line detector. It won numerous awards, including “Popular Mechanics Editor’s Choice Award in recognition of outstanding achievement in new product design and innovation,” also adding “you might as well have the best.” Car and Driver said the Passport 9500i “takes the next great leap forward.” And as good as it is, Escort has just released a new radar detector: they have unveiled the Passport 9500i. In their own words, “It provides the best long-range protection against every known radar and laser gun in use in North America, but also incorporates GPS accuracy to silence each and every false alert. It is by far the most intelligent, fully automatic radar and laser detector ever designed. You drive. It learns. End of story.” The Passport 9500ix comes pre-loaded with thousands of red light and speed-based cameras in America. You can also download updates, back up your data and stay on top of new threats by visiting their website.
Now that you’ve got some information, go out there and buy one! If you need to, save or bookmark this page so you’ll know which radar detectors to look out for!

Tools and Devices to Beat Police Cameras and Radar Detectors
Robert asked:
Since the beginning, law enforcement agencies and offenders have been in a cat and mouse existence. Our modern world has equipped our government troopers with enough electronic gadgets like street cameras, police radas and laser guns to keep track of traffic violators, over speeding motorists and catch them with their pants down. With the development of sophisticated technology, counter measures also plied the market, such as radar detectors, laser jammers and recently license plate cover spray, all designed to evade detection, which renders the job of troopers tough to handle.
What exactly are these devices? You might have noticed that our traffic signal systems have become quite sophisticated. Monitoring road traffic is now handled through the use of powerful computers and aided by street cameras, radar detectors, and laser guns. Should you commit a traffic violation, no officer of the law will accost and give you a traffic ticket. Instead, all of these offenses are recorded and a traffic incursion ticket is directly sent to your address. It becomes doubly difficult to dispute a traffic violation because said violation is electronically stored and detailed in a large database, complete with video cover and time.
A product that has been in use by many car owners is the radar detector. The idea behind this scheme is to provide warning signs once you drive along pertinent government installations like photo radars, red-light cameras and also speed cameras. These installations are good deterrents against those prone to commit road violations, drunk driving or drug related offenses.
For those in the habit of over speeding, the radar detector is no match for the laser guns of police troopers. Once a motorist detects the presence of these electronic gadgets, it detects too late since the laser gun needs only a fraction of a second to record the car’s speed. To evade detection, the radar detector must have a laser jammer to prevent the opposing laser gun from momentarily recording speed; thus, giving the driver time to slow down and cruise within the required speed limit.
Photo radars, red-light cameras and speed cameras are now widely used in major cities across the United States. These systems have become popular nowadays, because it is found to be very useful in tracking down traffic violators. No efficient counter gadget has yet been designed to limit its effectiveness except the license plate cover spray that hinders traffic cameras from reading correctly the violator’s plate number. This is a new, highly advanced technology that actively blocks and bars any system that employs a flash camera from taking a photograph of the license plate. In the absence of concrete evidence, traffic violators will not be charged.

3 Tips To Buying The Right Radar Detector
Brandon Hopkins asked:
There are many radar detectors on the market right now. Each one of them claims to have a single best feature. Some detect from the longest distance, while others claim to detect the most radar bands. Others claim to have the highest degree of accuracy and can tell the distance and direction of the radar gun.
With all these different features on the market, which one is right for you? What model of radar detector should you buy? How do you know it will actually work in your state? Is it legal in your state? These and other pressing questions are frequently asked. Here are 3 ways to know you are buying the right radar detector.
1. It detects the right bands for you state.
Some states use different types of radar guns, and unless your radar detector can pick up their signal, it isn’t any use. There is a whole slew of different bands of radar guns, X, K, Ka, POP3 K, POP3 Ka, Laser, etc.
First you need to find out which bands that your states uses. Then you need to find a radar detector that can pick up those bands. Not every radar detector can pick up every band.
2. Find the model you want.
There are hundreds, if not thousands, of reviews for nearly ever radar detector ever made on the internet. Now that you know what bands you need to detect, you need to find the right mix of price and features. Some people don’t mind paying $500 for a radar detector, some people want to pay under 100 bucks. Obiviously the more you spend, the more features you will get. And the amount you spend will usually determine the range that your radar detector can detect to.
There are many different websites that will allow you to compare different radar detector models. Once you have found the right model for your needs, find the right price. This usually involves going to a few comparison sites, and searching for that model of radar detector.
3. Make your purchase and install.
Some radar detector installations are as simple as plugging your radar detector into your cigarette lighter socket. Others are more complex and need to have wiring run throughout your car or truck. Depending on the complexity of the product, and your knowledge, you may or may not need to have your radar detector professionally installed. A great place to get a radar detector installed is a car audio store. These shops are experienced with running wire throughout cars, and have probably installed many radar detectors.
Keep in mind that radar detectors are illegal in some states, you should check with local law enforcement before purchasing and installing a radar detector.
A radar detector doesn’t make you invincible to radar guns, and it doesnt’t mean that you won’t get a ticket. You should always obey the speed limit.

Introduction To Radar Detectors
Stefan Rockhaus asked:
A radar detector is an electronic device used by motorists to determine whether their speed is being observed or not by a police officer. The objective of a radar detector is to protect the motorist from getting a speeding ticket from the officer who is using a radar gun.
Radar detectors were introduced in the early 1970’s. The term radar detector originated from technologies that were used earlier to detect speed.
Now the question arises, “What is radar?” Radar is a system used to measure the speed and location of any object. This system consists of two important parts – a transmitter and a receiver. The radio transmitter causes voltage fluctuation by oscillating an electric current at a predefined frequency. This oscillation of the electric field generates electromagnetic energy. This electromagnetic energy propagates in the air as electromagnetic waves. A transmitter consists of an amplifier and an antenna. While the former increases the power of electromagnetic energy, the latter transits it into the air.
The basic function of radar is to determine its distance from the destined object. For this function, the radar device emits concerted radio waves to observe any echo. If any object comes in the way of the radio waves, then it can be easily detected by radar with the help of electromagnetic energy. Radio waves constantly travel in the air at the speed of light. The distance of the object from the radar is determined by observing the time taken by the radio waves to return.
For measuring the actual speed of any object, radar can be used with a fact called Doppler shift. When any moving object passes in front of the radar, its echo will reflect the signals of the radar. The time taken by the radio signals to return after striking the object, and the frequency with which they travel, gives the actual speed of that object. If an object is coming towards the radar, then the signals will come back in a shorter period of time. It will increase the frequency and tells the actual time in which an object will cross the radar. This process depends on how fast the frequency will change. Traffic police use radar in the form of a radar gun, which is either hand-held or vehicle mounted, to detect speeding vehicles.
A basic radar detector detects police radar with just a simple radio receiver. In contrast, detectors that are more sophisticated comprise of a basic receiver along with a radio transmitter. A jamming signal is produced via this transmitter. It blends the signal of the police radar gun with extra radio noise. Due to this, a perplexed echo signal is received by the police radar gun, and the exact speed-reading cannot be taken.
Light-sensitive panels are being used in modern detectors which detect the beams from police laser guns. Lidar is difficult to avoid due to its concentrated beam, so it is quite possible that by the time the detector is able to detect it, the vehicle is in the beam’s sight already. For that, speeders also use a laser jammer. It works much like a radar jammer.
In conclusion, there are several systems available to detect radar, but none of these systems is a sure shot way to get protected against speed detectors. However, one thing that can be done to avoid speeding tickets is to ’slow down’.

Anti-theft solutions for car audio, GPS, radar detector, etc?
Jeremy asked:
Yesterday I purchased a GPS and I feel like I need to take some security measures for my car to prevent my electronics from being stolen. Along with the GPS I have an iPod connected to a Harman/Kardon Drive+Play unit, an Escort radar detector, and an older Alpine radio. As it stands, my car is begging for its window to be broken out and have everything stolen.

As it stands, my car is begging for its window to be broken out and have everything stolen.
I have a car alarm, but as everyone knows, they are almost useless.
I could remove every item (radio faceplate, gps, ipod, radar detector) and carry it with me every time I got out of the vehicle, but this is far too much trouble.
Is anyone aware of a security accessory for their auto electronics? I appreciate any help or suggestions.
