Wired. Parking sensors, in which the connection of sensors, the control unit and the display unit is carried out only with the help of wires. Such devices are simpler in design and (ceteris paribus) somewhat cheaper than wireless ones, but much more difficult to connect: after all, the wires from the rear sensors have to be pulled to the screen/indicators across the entire cabin, and their length can become a significant limitation for laying possibilities.

Wireless. This type includes models in which the connection between the control unit and the display unit is carried out wirelessly, in the radio range. This partially saves the owner from fussing with wires: the transmitter power is usually quite sufficient to install the main unit in the boot and not pull cables to the display through the entire cabin. However, do not be misled: "wireless" refers only to connecting the display, and you still have to lay wires during installation — at least from the sensors to the main unit.
— Overlay on the mirror. As the name implies, this type of parking sensors have a display designed to be installed instead of a rear-view mirror; moreover, such a display can be not only an overlay mounted directly on a regular mirror, but also a separate unit mounted instead of a mirror on the same mount. This can be very convenient due to the fact that the driver does not have to look for a place fo
...r a separate monitor. In addition, in this case, the data necessary for reversing — the view from the mirror and the readings of the parking radar — are compactly grouped in one place; and some models allow you to connect a reversing camera to the screen. The connection to the control unit can be either wired or wireless (both described above). However, the installation of overlays is combined with additional difficulties, because. mirrors in different models of cars can significantly differ in shape and dimensions.
