Compare Backup Sensors & Cameras to ParkFX

Get the Latest Information on the Most Reliable Backup Warning Technologies

Not all reversing aids are equal. The sensing technology and the indicating method are critical to your driving safety.

How a park assist system alerts you

One option is video, which at first seems like a great choice. But one major flaw with having a video camera affixed to the back of your car with a monitor on your dashboard is that it also forces you to look forward while backing up. That can disturb your perception, your reaction time, and feel very unnatural. They are also extremely expensive, and you'll pay thousands of dollars to have a video system attached to your car, whether from the dealer or an aftermarket supplier.

Compare that to other bargain basement devices which actually have LED displays (little red lights) on your dashboard. These are cumbersome -- almost useless -- for much the same reason as video: when you drive in reverse, you naturally look behind you, and you'll never see the little red lights. They are also hard to read in bright sunlight.

Some other bargain technologies use a tone which beeps more rapidly as you get closer to an obstacle. You can at least hear the relative distance just by listening to the beeps, but you have to practice a bit to really understand how far you are from danger.

That's why an audible voice sensor is best. It tells you in a spoken voice exactly how far away you are. Not only do you not have to awkwardly look forward at your dashboard, you'll know without guessing how much further you can safely back up.

How a reversing aid detects objects

If you've never seen or used a reversing aid, you might be surprised at how technically advanced they actually can be.

Reversing aids use a variety of technologies to sense an object behind the car. Some units use Doppler radar, and others use infrared sensors, but by far the most accurate method of detection is the one the U.S. Navy uses on its submarines: sonar.

Sonar can operate in any weather, including direct sunlight or rain. And it doesn't require that the car be moving in order to sense an obstruction.

Better than some automakers "detectors"

LaneFX actually shows you what's lurking in your blind spot!

Device Reads Email Messages to Drivers

Tech Digest reports on a new gadget and speech recognition system called iLane that provides drivers with a hands-free way of listening to email messages. iLane can also handle phone calls, calendar requests and SMS messages. The device plugs into the cigarette lighter.

iLane is a small device that interacts directly with existing Bluetooth-enabled handheld devices, allowing drivers to fully access their email in transit. iLane notifies the driver of incoming emails and other important information by reading a brief summary in a "natural sounding voice". The driver can then listen to the entire email message; forward or compose a response using verbal instructions. Phone calls, SMS messages, and a number of email attachment types can also be managed. In addition, filters can also be set to priorities mail, so you don't get hassled with that latest sales pitch from an online store.

Don't Be Blind Sided by Your Blind Spot!

Unlike other "radar" detectors, LaneFX has no learning curve. LaneFX is a WYSIWYG (What you see is what you get) system that uses what you already use - your vehicle's side mirrors - to show you what's in your blind spot zone. With its extensive customization options, LaneFX adapts to your driving style, not the other way around.

Don't forget: your mobile electronics retailer is best for installing your LaneFX system, but not factory systems like Volvo BLIS or ValeoRaytheon. Don't settle for the nerdy car gadgets, get LaneFX and get the latest driver safety technologies. Lane change or merge with the latest blind spot mirrors and auto safety technologies.

More than 2,400 children are accidentally backed-up over each year in the U.S.

And of those, more than 100 die. With the proliferation of SUVs and mini-vans, drivers aren't aware of the enormous rear view blind spots that prevent them from seeing what's behind them, especially small objects, animals, people, and children. Some of these blind spots are even greater than the length of an average driveway! Senators Hillary Clinton (D-New York) and John Sununu (R-New Hampshire) have recently proposed legislation requiring the U.S. Department of Transportation to issue regulations aimed at reducing accidents that frequently kill or injure children in cars. But until that legislation is passed, it's up to the driver to protect their loved-ones and prevent a tragedy by using a Park Assist system or a backup camera.

In fact, the Centers for Disease Control and Prevention estimated 2,767 people were treated in emergency rooms from July 2000 through June 2001 because of backovers. "This is a huge problem," Fennell said. "A lot of [the problem] is due to the change in our vehicle mix" that has more people driving tall-profile vehicles, she said.

Indeed, Fennell's research indicates that "in 60 percent of the [backover] cases, it's a truck, van or SUV that's involved," Fennell said. The reduced rearward visibility is caused by the design and tall profile of SUVs, pickup trucks and even vans.

The top edge of the tailgates and liftgates in these vehicles typically sits high and so do the vehicles themselves. This means that unaware children and small-stature adults and anything not tall enough to be visible in the rear window glass might be run over as the vehicle is backing up.

Consumers can choose from a wider range of aftermarket vehicle-backup systems since our last report, including new and improved designs.

All such systems are intended to help drivers detect objects within the blind spot behind the vehicle.

New are camera systems such as the Audiovox and ParkFX we tested that offer a “picture in the mirror” feature. The display is on a mirror that fits on top of or replaces the existing rear-view mirror, so you don’t have to choose between looking at the display and at the rear-view mirror while backing up. ParkFX also combines a camera with an audible sensor, so you can see and hear potential trouble. We would like to see more backup warning systems on the market that combine camera and sensor technologies.

Backup systems are typically marketed as parking aids, not safety equipment. But our tests show that the camera models can also help drivers avoid backover-accident injuries and fatalities.
