How to record from cameras with existing equipment?

Question

CCTV

there is such a device


, unfortunately there are no more identifying signs on it

, as I understand it, this is a simple analog-> digital converter, outputting images from cameras to a TV
who can tell what kind of device it is and how can I record from cameras, for example, on a PC?

I know very superficially how it all works only, for example, is it possible to receive a signal from this device on a PC and simply record it, for example, SmartPSS or a similar program?

This device is a DVR. Essentially a mini-computer with special software. A hard drive is inserted into it for recording video. Connect the monitor and mouse and set it up using the scientific poke method (the interface may differ for each model, but there is nothing complicated there). Picture from Ali:
