Which is better, reversing camera or reversing sensor ?

Entry

Road safety is every driver's priority. One of the most difficult maneuvers, especially in congested cities, is reversing. Modern technology offers two popular driver assistance solutions - reversing cameras and reversing sensors. Which one is better? In this article, we will discuss the history, operation, advantages and disadvantages of both systems and compare them in a table and on a graph.

The History of Reversing Assist Technologies

The first solutions to assist in reversing appeared in the 1950s, but they began to be used on a mass scale only at the beginning of the 21st century. In 1956, the Buick concern presented a concept car model Centurion with a reversing camera, but this technology was not yet available in mass production. It was not until the 1990s that the Japanese brand Toyota implemented the first reversing camera systems in selected models.

Parking sensors, also known as reversing sensors, gained popularity in the 1980s. The system was first used by the Italian company FIAT in the Tempra model. The technology developed rapidly and is now standard in many cars.

How does a reversing camera work?

A rear-view camera is a device usually mounted at the rear of a vehicle that transmits an image to the dashboard screen or rear-view mirror. The camera provides the driver with a wide field of view and makes it easier to assess the distance to obstacles.

System components:

  • Camera mounted in the rear of the vehicle.

  • LCD display or multimedia screen.

  • Parking assistance software, e.g. guide lines.

How does a reversing sensor work?

The reversing sensor is a system that uses ultrasonic waves to detect obstacles behind the vehicle. When the car approaches the object, the system warns the driver with a sound and possibly a visualization on the dashboard.

System components:

  • Ultrasonic sensors mounted in the rear bumper.

  • A control unit that analyzes data from sensors.

  • Audible and/or visual indication on the dashboard screen.

Advantages and disadvantages of reversing cameras

Advantages:

  • Clear view of obstacles.

  • Ability to see low objects such as curbs or animals.

  • Helpful lines to help you judge distances.

Defects:

  • May be ineffective in bad weather conditions (rain, snow, fog).

  • Requires a clean lens to function properly.

  • Higher installation cost than reversing sensors.

Advantages and disadvantages of reversing sensors

Advantages:

  • They warn with an audible sound so the driver does not have to look at the screen.

  • They work effectively in all weather conditions.

  • They are cheaper and easier to install than reversing cameras.

Defects:

  • They do not detect very low obstacles.

  • They may not function properly in the presence of strong ultrasonic interference.

  • They do not provide visual information about the surroundings.

Technology comparison table

Characteristic Reversing camera Reversing sensor
Obstacle visibility Very good Limited
Installation cost Tall Short
Weather resistance Limited High
Audible warning NO Yes
Detection of low objects Yes NO
Maintenance Requirement Yes (cleaning) NO

When to choose a reversing camera and when to choose sensors?

  • Reversing camera It will work best for drivers who often park in tight spaces and want to have full control over the car's surroundings.

  • Reversing sensors are a good choice for those who prefer a simple and effective solution without having to watch the screen.

  • The optimal solution is to combine both technologies – the camera provides visualization and sound sensors warn of obstacles.

Summary

Both the reversing camera and the reversing sensors have their advantages and disadvantages. The choice of the right solution depends on the individual preferences of the driver and the conditions in which the vehicle is moving. The reversing camera offers better visibility but is more expensive, while the sensors are cheaper and effective in all conditions. The best solution is to use both systems, which ensures maximum safety when reversing.
