Intercoms with built-in quadrator

Built-in quadrator

— quadrator is a device that allows you to display the signal from several cameras on one display. The name comes from the fact that classic quads support 4 cameras, and the screen connected to such a device is divided into 4 parts — an image from a separate camera is displayed in each corner. However, in modern electronics, such devices can also work in other formats — for example, output images from cameras alternately. Anyway, this feature is convenient when working with several cameras — without it, the quadrator would have to be purchased separately.
