Reversing radarPurchase knowledge
So how to choose a parking sensor? Mainly judge from the following aspects:
1. The number of probes
There are 2 probes, 3 probes, 4 probes, 6 probes and 8 probes in the reversing radars on the market. The reversing radars with 2-4 probes are generally installed incarOn the rear bumper, the reversing radar with 6-8 probes is generally installed with front 2 rear 4, or front 4 rear 4. Generally speaking, the number of probes determines the detection coverage capability of the reversing radar, which can reduce detection blind spots. The reversing radar with more than 6 probes can detect the front left and right corners when reversing.
2. Function
From the aspect, it can be divided into LCD distance display, sound prompt alarm, azimuth indication, voice prompt, automatic probe detection, etc. The more complete function of the reversing radar should have distance display, sound prompt alarm, position indication and other functions.
3. Performance
The main performance of a reversing radar with good performance mainly includes:
(1) Sensitivity, whether the reaction is fast enough when there are obstacles.
(2) Whether there is a blind spot.
(3) Detection distance range.
Each reversing radar is undergoing automated on-site detection and testing. According to its engineers and technicians, the detection range of general reversing radars should be 1.5-0.3 meters. Some brands of reversing radars are only 1.2-0.4 meters sensitive due to their insufficient sensitivity. , It will bring certain difficulties to the driver's judgment and taking measures. In order to make the domestic reversing radar more standardized, the Bowen BOWON reversing radar is contacting relevant national departments, hoping to formulate a common domestic detection standard.
4. Installation method
There are currently two installation methods, one is the external paste type, this method is to directly attach the probe to the bumper without drilling holes. The main product is 2 probes, but it does not look very beautiful after installation, and it is basic Need not. The other is the built-in type, that is, the probe is installed on the bumper through the hole, which is mostly used in the original car. It should be noted that the color of the probe should match the color of the car body.
5. Seller
Nowadays, the quality of auto supply stores is uneven, and the level of the installation master is naturally high and low. It is recommended that you choose some reputable merchants when installing.
Through the above understanding, I believe you have a preliminary understanding of the reversing radar. Specifically, in actual purchases, we have to shop around and try our best to choose brand manufacturers. In this way, the technology is guaranteed and the service is in place.
