Recommendations for choosing a product

The main element of conventional holes - wide-angle lens "Fisheye", which provides a good overview of the space. In electronic versions of the camera is used.

To begin, analyze what types of holes are:

	Standard door peephole. This embodiment is simple and consists of two parts - inner and outer, which are twisted together. The cap structure may be present to close the opening against the ingress of light.
	Panoramic peephole. Its distinguishing feature - the lens is divided into two lenses. This design allows you to skip the larger luminous flux. To view the image, optionally be back to back, can be placed on the side of the structure.
	System for double doors. This can be a standard or panoramic embodiment. The design consists of two parts, setting accuracy should be particularly that the elements are aligned.
	bulletproof option. Used on the bulletproof door leaves, to ensure the reliability of the design. By mounting procedure is no different from the conventional embodiment.
	Peephole, periscope. This option is ideal for those who have small children. You can watch in the normal position, and at the bottom, which is very convenient if you want to exclude the option of opening the door to strangers.

	Videoglazok electronic type. Earlier versions of video signal adjustment required for transmission to the monitor or TV. Modern technologies allow to make a compact and easy option that will set any person without difficulty.

If you have decided on the type, it is necessary to deal with a number of criteria that are taken into account when choosing:

1. viewing angle. The higher it is, the better it is clear space in front of the entrance. At cheap embodiment the angle is 120 degrees, have improved - 180 degrees. Most modifications are qualitative review of more than 200 degrees, this allows to eliminate the distortion of image boundaries;

The viewing angle depends on the shape and arrangement of the lenses

1. The thickness of the door leaf. There can be three versions of products:

• to 60 mm;
• to 100 mm;
• over 100 mm.

Any version of the eyelet is adjustable 20-30 mm due to the thread. Some models are supplied different sleeve, so you can choose the optimal solution for your door;

A threaded connection allows to adjust to the thickness of the door leaf

1. The diameter of the eye. This rate determines how big a hole to be drilled. If the new designs you can choose any option, the replacement of the old elements of the easiest way to choose a product of the same size. In most cases, the inner diameter portion is 20 mm;
2. Material. Optics may be plastic or glass, the price far below the first embodiment, but the second is much stronger and more durable. The housing can be made of plastic or metal, the second option is preferable, although it is more expensive.
