What is best intercom system I can install?

If you want to add features to your intercom, such as remote network access, connect a large number of door stations and monitors, fine-tune the security functions and features - you will most likely have to choose ip video intercom. If you only need audio-visual control of visitors and the possibility to open the lock with a button, an analog intercom will be fine.

Intercom, like video surveillance, is globally divided into 2 standards: analog (digital-to-analog) and digital (ip, network). Not to go into the detailed technical characteristics of these standards, we can highlight the difference between them: digital-analog equipment for intercom provides acceptable quality of audio and video information, but somewhat limited in functionality.
