That Beeping (or Talking) Sound Could Save You Money
With as much time as we spend in our cars these days, along with busy, hectic schedules, you’re bound to go over the posted speed limit every now and then. Sometimes it’s to pass another vehicle or stay with the flow of traffic; other times it’s because there’s an open road ahead of you and you don’t pay attention to the speedometer creeping up and past the limit. In either of these cases, law enforcement can pull you over and ticket you, even if your speed wasn’t endangering anyone else. And that ticket could easily break a delicate budget or result in missed work to attend court or traffic school.
But what if you could avoid the whole situation altogether? Wouldn’t it be great to have a little box that warned you ahead of time when there was a law enforcement officer up ahead checking your speed? The good news is, there is, and we have it!
Speed-checking devices used by law enforcement use different forms of radar and laser technology to judge the speed of a passing car. Radar detector systems use equally advanced technology to “detect” when these devices are being used, and if the device is ahead of you on the road or behind you. The best part is, they pick up the signals used by these devices before your car is in range, giving you the warning and time you need to slow down.
Since radar detectors have been around since 1968, the technology they contain has grown. Of course, they’ve had to get better as radar guns used by law enforcement have gotten better (many now can sense laser light as some law enforcement agencies now use LIDAR—or lasers— to pinpoint speedy drivers). But just as important, they’ve gotten smarter, adding more convenient features for drivers.
For instance, where original detectors would simply beep, some models now speak to you when a radar signal is detected. Others include informative displays to indicate the types of radar or laser being used, and how far it is from your vehicle in any direction. Another recent convenience feature is the use of GPS (global positioning satellites) to track common “speed traps” or areas with frequent false alarms, giving the user the ability to mark or ignore these specific areas. Also new are onboard databases that store the locations of traffic cameras, and compatibility with smartphone apps.
Obviously, the ability to detect and thwart law enforcements’ ticketing efforts doesn’t sit well with everyone, and several states restrict the use of radar detectors in one way or another. Most states allow their use in passenger vehicles, though some, such as California and Minnesota, prohibit the use of windshield-mounted models.
As a result, we have different options to fit drivers’ needs and comply with the law at the same time. We can design customized systems in which the radar detector is permanently and tastefully installed in your vehicle. All it takes is a consultation with one of our experts, and we’ll recommend the right system—with the right features—to give you a worry-free drive.
Different Types of Radar/Laser:
X-Band Radar: 10.5 to 10.55 GHz — Dating from the 1950s, X-band radar is the easiest to detect because of its lower frequency and higher power output. Depending on terrain, temperature and humidity, X-band radar can be detected from a distance of 2 to 4 miles, yet it can only take accurate readings of speed from a distance of 1/2 mile or less.
Unfortunately, police radar is not the only source of X-band signals. Garage door openers, microwave intrusion alarms, microwave towers, and other high-tech equipment can fool a radar detector into giving off an X-band alert. Filters and redundant sampling are used to combat this “falsing.”
K-Band: 24.05 to 24.25 GHz
K-band, the most common type of police radar, made its appearance in 1978. The first K-band hand-held radar guns could only be used from a stationary position. Later, a “pulsed” version was introduced that could be used from a stationary or moving vehicle.
K-band radar waves have a relatively small wavelength so they are more easily absorbed by water molecules in the air. At the power level found in police radar guns, K-band has an effective clocking range of about 1/4 mile. Depending upon terrain (around a corner, over a hill, etc.), K-band waves can be detected from a range of 1/4 mile to 2 miles.
K-band guns also have what’s known as “Instant-On” radar. This keeps the transmitter in “hot standby” mode, ready to be activated by an officer when the target is within 200-300 yards. If it’s been aimed at you, your speed has been measured by the time the detector alerts you. If it is being used to target vehicles ahead of you, your detector may provide a warning in time for you to slow down and avoid a ticket.
Ka Photo Cop and Ka Wide-Band: 34.2 to 35.2 GHz
In 1987 the FCC allocated a frequency on yet another band, Ka, for police radar use. With that came the introduction of photo radar (also known as “photo-cop”). The photo-cop system works at 34.3 GHz and combines a Ka-band radar gun with an automated camera.
A vehicle approaching at or above a predetermined speed will trigger the camera. The photo shows the front of the vehicle, license plate, driver’s face, the date, location, and time. The unit can clock and photograph up to 200 vehicles per hour. Alleged speeders are not stopped. The film is processed and a ticket is mailed to the registered owner of the vehicle, ordering him or her to pay the fine or appear in court.
Photo-cop’s effective range is 120-300 feet and it transmits a continuous signal which is a plus for radar detectors. The distance at which it can be detected varies depending upon a detector’s Ka-band sensitivity. Better detectors can typically sniff out a photo-cop system 1/4 to 1/2 mile away. Only a handful of cities use photo radar. Industry sources predicted widespread interest and expanded use, but that has not been the case. Legal controversies along with prohibitive expense have caused officials to stick with more traditional methods of speed detection.
The FCC later expanded Ka-band radar use to a range of 34.2 to 35.2 GHz. This became known as Ka Wide-Band.
Ka Super Wide-Band: 33.4 to 36.0 GHz: The introduction of the “stalker” radar gun raised the stakes in the detection game. Unlike all previous guns, the Stalker can be FCC licensed for any frequency in the Ka-band between 33.4 GHz to 36.0 GHz, and so cannot be picked up by detectors designed only for X, K, and photo radar. Stalker guns are being used in more than half the country. In response, manufacturers have developed detectors with “Super wide-band” technology that sweeps all of the Ka-band allocated to radar, as well as providing continued protection against X, K, and photo radar.
Laser: With the help of the federal government and the insurance industry, the laser speed gun has found its way into the hands of state and local police in at least half the country.
The advantages of a laser gun are compelling: the laser light beam is far narrower than a radar beam, allowing more accurate pinpointing of a specific vehicle; and the time needed for capturing a speed reading is less than half a second versus 2 to 3 seconds for radar.
The drawbacks are also important to note: laser guns are very expensive, they can’t be used from a moving vehicle or from behind glass, and accurate aiming requires a tripod or a very steady hand.
Despite initial claims that the energy from a laser gun is not detectable, it is. And as the laser beam moves away from the laser gun, it widens and becomes easier to detect.
Vehicle speeds are typically measured at roughly 1,000 feet (1/5 mile); at that distance the laser beam is over 3 feet wide. Many of the laser detectors in use have a working distance of approximately 1-1/2 miles (at that distance a laser gun’s beam covers two lanes of traffic).
VG-2 Radar Detector Detection: You can think of VG-2 as law enforcement striking back against radar detectors. VG-2 identifies vehicles with operating radar detectors on board. VG-2 Guard emits an alert and shuts down when a VG-2 unit is sensed. “Shadow Technology” shields the detector from VG-2 without interrupting radar and laser protection.
