The reversing image on the car suddenly doesn't look like it. What is the reason?

1, whether the line is connected properly.

2. Check whether the trigger wire is connected after reversing.

3. Is there voltage on the video connector?

4. The camera is broken.

Matters needing attention

When choosing a reversing image, you should pay attention to whether it matches your own model, which can be considered from the aspects of camera model, power supply voltage, screen size, waterproof, earthquake resistance and anti-interference.

First of all, if it is used in a car, the camera model (waterproof and night vision functions are optional), screen size (3, 5 and 7 inches) and power supply voltage (12V) can be considered, and trucks, buses and other large cars are 24V.

merits and demerits

1. Compared with reversing radar, reversing image has the following advantages:

Installation is simple. Generally, ordinary single-channel output of reversing images only needs to connect the positive pole of the power cable to the positive pole of the reversing lamp, and the negative pole of the power cable to the negative pole of the reversing lamp or ground (GND). We can simply understand how to arrange cables according to different models, and the camera can be installed in an easy-to-install position.

At a glance, after the vehicle is engaged in reverse gear, the physical scene behind it can be clearly seen, which is convenient for the driver to judge.

2. Compared with the reversing radar, the reversing image has the following disadvantages:

Initiative, when reversing, the driver needs to observe the dynamics in the display screen first, provided that you need to see it to understand the situation, but the reversing radar can give a sound reminder when you observe whether there are obstacles approaching the car on the left and right. Such as: "Left danger, etc."
