How we test
To test the backup systems under identical, repeatable conditions, we built an indoor test rig simulating the rear end of
a typical SUV. Each camera was installed on the rig successively, then subjected to a series of tests.
The overall score factors:
The best performer, Hitchcam VideoMirror, could scan an area more than 6 feet high and 17 feet wide, measured 5 feet behind
the vehicle. The worst system was the VR3 VRBCS300W, which pictured an area only 14 inches high and about 6 feet wide. As
for detecting a 6-inch-tall object, those cameras could see it at ranges as close as 14 to 18 inches.
We used the built-in backup camera of a 2007 Chevrolet Suburban as a reference. It was better than the top-rated Hitchcam VideoMirror and has a larger screen integrated into the dashboard so it doesn't block forward vision.
The overall score factors:
- How well the cameras could see objects in darkness, using just backup lights for illumination. We found a wide range of performance.
- The height and width of a cameras' viewing area, using a target positioned five feet behind the "vehicle."
- How close to the rear bumper a 6-inch-high object could be placed and still be within camera range.
