Unfortunately, it turned out that the peephole viewer I bought was completely unsuitable. After installing it (I live in a terraced house), I found that the image of someone standing at the door was very dark—you could only see a black outline of the person. There was no way to make out their facial features. I mention that I live in a terraced house for a reason. It turned out that the very bright background behind someone standing at the door creates a strong contrast, and the camera in the peephole simply can’t handle it. I really regret that this product isn’t suitable for my home. I made the only sensible decision and returned it.
+None
−The camera can’t handle a bright, high-contrast background
