Prevent an Accident Today with a Backup Sensor

The Backstopper CA-5009.II is a rear impact warning sensor system designed to aid the driver when backing up their vehicle. Unlike the other systems, the CA-5009 uses only an external buzzer for audible warnings. It also includes (4) ultra-sonic sensors with "quick disconnect" waterproof connectors in a 25ft. cable length.

The external plug-in style buzzer will give the driver audible warnings of distances by sounding off four distinct tones for notification. Since the buzzer is plug-in style, it can be mounting up closer toward the driver so they can hear it better. The sensors wide detection angle will alert the driver of any small children, pedestrians, animals or small unseen objects such as bicycles or parking poles. This makes it very convenient for parking in a parking garage, a crowded lot or even in your own driveway.

CA-5009.II Features

  • Reverse Parking Sensor System with Audible Buzzer (No LED Display)
  • (4) ultra-sonic sensors with "quick disconnect" waterproof connectors (25ft. length)
  • External buzzer for audible warning (No LED display included)
  • Buzzer can be located anywhere on the vehicle
  • Four-stage audible obstruction warning

  • Hole saw bit included for installation of the sensors
  • Authorized Internet Dealer

Good product with minor limitations

July 17, 2012

The scanning depth / length seems to be shorter than advertised. The high/low adjustment feature on the beeper is great. The sensors beep sometimes when no objects are in the scanning field.
But once you get used to the slight false alarms and short scanning depth it seems fine. I coupled this with a back up camera so between the two systems I have a good blind spot / back up coverage for my Jeep Wrangler. Easy to install.

Relocation of the beeper and the module and installation is a breeze. However, the sensor module is weak. Sometimes it works sometimes it doesn't.

Want to add backup sensors 2015 mustang with backup camera?
A shopper on Dec 7, 2015
Best Answer: There are some who would say that having a backup camera is sufficient. If that is your question, I would suggest that having both is an extra measure of safety. I personally don't understand why the manufacturer does not always include the backup sensor when a camera is provided since the additional cost is low. Certainly the sensors can be added without impacting the backup camera.

Are longer sensor cables available for the CA-5009.11 for installing in a motorhome?
Butch on Aug 1, 2014
Best Answer: Since the exterior sensors are in the rear bumper and the module needs to be near the cable going to the back up lights the only variable is where you put the speaker. It's plenty loud and you should be able to hear it wherever you place it in the interior of the motorhome. The cables from the sensors to the module are really long, I probably folded up 10 feet of cable from each one in my volvo's wheel well.
