Magic eye type

As you may have noticed throughout the text, there are two main types of magic eyes: traditional and digital. But what exactly are the advantages and disadvantages of each? We explain them to you!

The traditional magic eye is the one that has been used for generations, the most common in flats all over the country. It is a simple, practical and very cheap item. It is ideal for those looking for a model just to see when someone rings the doorbell, to confirm identity.

With many more functions, the digital magic eye guarantees even greater security for your home. They can capture images and videos of who passes by your house. In addition, some models even have a motion sensor.

If for some reason you are looking for greater security for your flat or house, this is a great option. In addition, the digital models also have a wider angle of vision than the traditional ones. Their disadvantage is the price which is much higher than the traditional magic eyes.

Material

The body of the magic eye is usually made of two materials: metal or plastic. If possible, opt for metal, which is more durable and resistant to external conditions.

The lenses can be made of plastic, glass or glasses optics. The plastic ones, besides attracting dust, are more fragile and can accumulate static electricity, losing image quality.

Those made of glass and optics are more suitable. The glass one, despite the higher price, provides more durability, however, it is a little more fragile than the glasses' optics.

Viewing angle

Each model of magic eye has a certain angle of vision. Digital models usually offer a 110° view, so you can even see if someone is crouching down.

However, there are also models which offer a 180° view. If possible, opt for a model that allows you to have a good angle of vision, to see even hidden or crouched people. This way, you guarantee greater security for your home.

Door width

The most common door thickness size is between 30mm to 55mm. If this is the case, there is no point in buying a 65mm wide magic eye, for example.

Each model has a size, and it is necessary to measure your door to know which magic eye you should purchase.
