Intercoms with built-in memory
— the presence in the design of the intercom of its own built-in drive with the ability to record and rewrite data at the user's command. This data can be different: visit logs with photos of guests, conversation records, etc., it all depends on the specific model. However, anyway, the built-in memory allows you to do without external media in the form of memory cards (see "memory card slot"), it works faster, but it costs noticeably more.
