Hello,
I am exploring aftermarket parking sensors. It seems like most sensors have a dead zone of at least 20 cm. Are there parking sensors with a smaller dead zone?
Edit: I live in the area of Tel Aviv and parking spots are hard to find and so it is really helpful to park in tight spots.
I’d suggest going with a backup camera instead. Make sure it’s aimed so that you can see your own rear bumper. Then you don’t have to try and interpret whether the solid beeping means you’re 20 or 2cm from the other car, you can see it for yourself.
Of course, there’s still the front of the car to worry about, but at least you’ll have the back covered.
GM used sound to show location when backing up about two generations ago. We had it on our 2003 Silhouette. They now use cameras, and I think it’s an improvement.
My 2019 Nissan Frontier has both. However, the truck’s basic design came out in 2005, before backup cameras were common so this may just be a holdover with the camera added when they became legally required.
We have rear blind spot radar and a rear view camera on our 2019 Odyssey EX-L. The blind spot monitor is more for backing into traffic and lane changes when underway. That stuff is too expensive as an add on for existing vehicles IMO, especially for parking.
