Scan distance

Working distance range of parking sensors; in other words, this is the interval from the response threshold to the smallest distance at which the device is still able to provide sufficiently reliable data on the distance to the obstacle.

The threshold of operation of modern devices usually does not exceed 3 m, and more often it is in the range of 1.5 – 2.5 m; the sensors themselves are capable of providing a longer range, but in fact there would be little benefit from this, but there are plenty of reasons for unnecessary worries. The minimum distance, usually, is 0.1-0.3 m (10-30 cm); a closer entrance is usually perceived by the device as a close approach, with a corresponding indication (for example, the transition of the sound signal to continuous). And if the response threshold is more of a reference value, then you should pay closer attention to the minimum distance, especially if you often have to deal with cramped conditions (for example, manoeuvring at a difficult entrance to a small garage). Indeed, in such cases, it is important that the parking sensors retain the ability to accurately indicate the distance for as long as possible, without switching to the “close” mode.
