Vehicle Tracking

By Nahshon Roberts

A photo radar is designed to photograph drivers who travel five to ten miles per hour over the speed limit. These photographs, along with particulars such as date, time, location, and vehicle speed, are then mailed to offenders.

Anatomy of Photo Radars

How does photo radar work? Photo radar is made up of the following:

? a high speed traffic camera and flash unit

? a narrow beam, low-powered Doppler radar antenna aimed across the road ? a computer that records information, such as date, time, speed, and location of the violation

Photo radar works this way. First, the system is hoisted onto a police vehicle that typically patrols areas where overspeeding is a problem. Then, it catches speed demons and those who run against red lights. Drivers can see their vehicles’ speed from a reader board found in the back window of the police unit display.

Beating Photo Radars

Many disgruntled drivers have successfully parlayed their dislike for photo radars into a lucrative business. They produce products that supposedly protect drivers from being photographed by photo radars. Below are some of the products and a brief description of how they are used.

? Radar Detectors

A radar detector detects the presence of photo enforcement devices. Accordingly, it assists drivers in beating photo radars by warning them of photo radar presence. This gives drivers time to slow down. Many claim radar detectors are effective. One problem with radar detectors, however, is that these do not work with red light cameras that measure speed using sensors embedded in roadways.

? Flash-back device

What senses the flash of a photo enforcement camera and immediately flashes its own strobe light onto the license plate to make license numbers invisible to cameras? Why, a flash-back device, of course! Flash-back devices are highly popular, especially because they’re cheap. A study, shows however, that flash-back devices are ineffective in beating photo radars when Redflex sensor-based photo enforcement cameras are used.

? GPS-based warning systems

Radar detectors are illegal, and in some states, use of flash-back devices are implicitly prohibited. What do drivers interested in beating photo radars without breaking the law do? They buy GPS-based warning systems. These devices, which are very popular in European markets, has just recently become available in the United States.

This is how a GPS-based warning system works: you download the location of speed enforcement cameras into a GPS system. Because your system now has a map of camera locations, it warns you to slow down every time you are close to a photo radar.

While a GPS-based technology may seem infallible, it is not without its faults. To be effective, it relies on your knowledge of photo radars’ locations. This is knowledge you may not always have. All it takes for you to get a citation is one speed camera unregistered in your GPS system.

? Plate covers

Plate covers are cheaper alternatives to the three technologies I have previously discussed. These covers go over your license plate, keeping it visible to anyone who is directly behind your car. In certain angles, however, a portion of your license plate cannot be seen. Some states, particularly Washington, D.C, penalize the use of these covers by as much as $300. Other states are silent regarding their use. Should you ever decide to go for plate covers, note that they do not work with motion video cameras.

? Photo spray

This is the least effective method for beating photo radars. It is sprayed onto license plates. Its high gloss finish is said to reflect the light flashed by cameras, resulting in overexposure of photos. Experts warn that photo sprays are only 45% reliable in reflecting camera light. Furthermore, though photos are overexposed, a quick scrutiny of their negatives will yield the exact sequence of a license plate’s numbers and letters.

Beating photo radars requires cunning and the proper tools. When caught, you would be held legally accountable. You must, therefore, carefully consider what technology to use and whether you are ready for repercussions. Then, and only then, should you use any of the above-mentioned technologies.

You’ve been playing golf forever and you still stink when you’re out on the green. You’ve got all the necessary gear, all the training stuff, and you’ve watched videos and tutorials online. So, what’s the problem?

Even if you play golf as a hobby, you’ll always need to be concerned with correcting golf swing problems. There’s nothing more rewarding than noticing that you’re scores are getting lower. You’ll gain more confidence and feel better about your game.

Here are some simple tips for correcting golf swing problems.

Keep Your Eyes Open

When you go golfing with friends, watch them. During the first few holes, check out everybody and see who’s the best player. Don’t worry about all your own slices and mistakes; find out who’s the best in the group and study their moves.

You’d be surprised what you can learn just by watching others play. If you don’t get out to play as much as you’d like to, watch pro golf on TV. Instead of thinking about how impossibly good the players are, watch what the do and pay attention to their technique.

Practice Practice Practice

I can’t write tips for improving your game without mentioning practice. Practice a lot. Okay, I mentioned it, so let’s move on!

Watch Yourself

When you’re doing all this practicing I mentioned above, videotape yourself and watch your swing. This can really help you notice things you wouldn’t have noticed before. When you are practicing, you’re so busy DOING it, that you might not notice a mistake you’re making.

Watching the video back, you might notice that your posture is a little awkward, or your address a little off. You can watch different shots and see how consistent your set-up is. You can see the angles from the outside, and you can even compare your swings with those of your favorite golfers.

Just remember to erase them when you’re done. There’s no reason to keep an archive, and let’s face it, it’s a little weird to have a hundred videos of yourself practicing golf!

If you’re not into the audio-visual side of things, practice in front of a mirror. This will help too, and you can practice your “Nice shot!” face.

No More Slicing

The most common problem with most golfers’ swings is the dreaded slice. The slice is basically when the ball goes veering off to the right of where you meant to put it (of the left, in the case of lefties).

If you slice a lot, you are probably swinging in too much of a downward motion. In other words, your swing plan is too steep.

Try flattening it out. If you flatten it out too much, the ball will start veering to the left (or the right, in the case of lefties). Try to find the right balance between too-steep and too-flat, so that the ball goes just where you want to put it.

Sometimes slicing is caused by improper grip or stance. Make sure you have the proper address before you take your golf swing, and you’ll eliminate this problem. For more info see
