Review on Aluminum and Black Door Scope DS2000 Door Viewer - Improve Your Home Security by Cornelius Mosley

Good Quality. This gives a good picture of the other side of the door, but there are a few factors that I feel are not addressed in the product description. I bought it for the side door of my garage. There are no windows on this side of the house, and instead of putting a window in the door or replacing the door, I opted for a door view. One of these was on display in a shop I worked at about 25 years ago. (Not new technology as the box says.) It looked impressive on display, but not so much in real life. First, the picture is upside down. It's like looking at the other side of the door in a mirror. You can see a clear image only when you stand in a certain spot. You have to find out where this place is and get used to it. You can't see things as clearly from afar as you can up close. So if you're expecting to see someone walking down the sidewalk 30-40 feet away, forget it. The description states that you can see clearly up to two meters away. I think that's out of scope. Four or five feet is more like it. If someone is right outside your door, you can see them, and that's a good thing. Even as a mirror image. So, the door visor works, but I'm not sure if it's worth the price. Keep all of this in mind before installing a 2-3/8 inch hole saw on the door. This size is not standard for any other alternative that I know of.
