Video and audio intercoms- why I prefer wired.

I have some familiarity with both video and audio intercoms and have retrofitted older audio intercoms with newer hands free video intercoms successfully. I don’t do wireless intercoms at this point, but I can point you to people who do if this is required because of difficulty with installation, damaged wires etc Wired is preferable in my opinion. When you get a wired intercom, the money goes mainly into the installation, which is normally a reliable long term investment compared with wireless intercoms which if (or when) they fail, can really only be economically replaced as a whole system, the product life isn’t long on intercoms, and systems rarely have interchangeable parts. On the other hand, wired intercoms sometimes have relatively inexpensive components which can be replaced when they fail and the maininvestment (wiring) is intact.
