Electromagnetic Parking Sensor Invisible | Proxel Electromagnetic Parking Sensor invisible EPS | no holes on the bumper Electromagnetic Parking Sensor Invisible | Proxel Electromagnetic Parking Sensor invisible EPS | no holes on the bumper On this page are reported the main differences between the two technologies on the market: the parking sensor EPS® and parking sensors called also back up sensor with ultrasound.
| EPS® by PROXEL | ULTRASONIC SYSTEM | |
Sensors |  The installation does not require any modifications outside of the car, the antenna sensor is placed inside the bumper. |  The ultrasonic backup sensors are easily visible and vulnerable. |
Obstacle |  The parking sensors EPS® are able to detect any kind of obstacle even with the most varied forms. |  The ultrasonic backup sensors have difficulty to detect inclined surfaces or slightly reflective obstacles as shrubs and wire mesh. |
Distance |  Capability to approach the obstacle up to few centimetres. |  The ultrasonic backup sensor is unable to distinguish distances below 30 cm. |
Protection zone |  The parking sensor EPS® protects the bumpers on its entire length without discontinuity points. |  The ultrasonic backup sensors fails to protect the entire length of the bumper and has few dead detection points. |
