What do you need in order to feel safe? Let's start with a solid front door and a good peephole. A peephole is a device that helps to inspect not only the staircase, but also to control the space behind the door. A feature worth paying attention to when buying is the viewing angle, which depends on the thickness of the door and on the size of the peephole itself. The larger the door peephole itself, the greater the viewing angle (and it can reach 180 degrees).

Almost all door peepholes have a lens, which is a lens that faces the object and an eyepiece in the form of a lens that is turned towards the observer's eye. There are also external and internal nuts, from 3 to 14 lenses, and sometimes periscopes (mirrors). The most popular are eyes with four lenses, which can provide 180 and even 200 degrees of view without distorting the image. The diameter of the eye affects not only the viewing angle, but also the visibility in low light, and also helps to observe at a distance of 5 centimeters from it. The bigger, the better. But do not forget that you need to determine the diameter before buying in order to avoid a headache on the topic: how to insert a peephole with a large diameter into an opening with a small one, and vice versa.

What does the price depend on? Answer: from the material of the optics of the eye and the material from which it is made. The worst option for you is the optics and the plastic “product body”. The best is glass optics, and the "body" is made of metal.

For the frequent purchase of a door, you immediately purchase a built-in door peephole. Standard eyes are suitable for doors with a thickness of 30–55 mm; so-called long - for a thickness of 55-100 mm; and if more than 100 mm, they are extra long.

If you touch on the question of beauty, then a black metal eyelet looks better than a colored one. But, it will be more practical to purchase a door peephole made of steel, because it does not scratch, and not brass (gold color), because it darkens over time.
