The daytime image is very good, not very good at night. After 8-9 months, the image completely broke down and appears very blurry.

I give it one star because there is no zero.
The camera, from the moment it was installed, did not satisfy me neither with the resolution nor with the color accuracy (it rendered the green of plants as purple), but the worst came two weeks later when it got moisture and now you can hardly see anything and it's only a matter of time before it stops working.
Before, I had a cheap Chinese one that lasted for years before it broke.
Disappointment and wasted money.

You get what you pay for!
I had bought a cheaper camera similar to one with LED lighting, and with the first rain, it got water inside and became useless.
I have had this specific one for a few days, but I have tested it with car washes and it has no issues whatsoever!! If anything comes up, I will mention it!
The build quality is excellent! It is not even plastic, it is metallic and has a glass cover on the outside.
Now, in terms of image quality, I am thrilled, especially at night!! It has night vision and thanks to the infrared, it shows clearly even in complete darkness!! Of course, the reverse lights help, but I am completely satisfied with the purchase that cost me around 40 euros with shipping
