Intercoms Wireless for Home, Full Duplex Wireless Intercom System for Business, Room to Room Intercom Two Way Real-time Intercom with 1200 Feet Range (3 Stations)

Für Wände in den USA, die nur aus Pappe oder einer Schicht Holz bestehen bestimmt wunderbar. Bei massivem Mauerwerk ist die Reichweite auf ein Zimmer begrenzt. Somit unbrauchbar.

Amazing. Works from house to metal shop 500 ft away. Perfect.

This wireless intercom system works great for room-to-room communication with clear audio and no delays. The full duplex feature allows real-time conversations, and the 1200-foot range covers large spaces well. Setup is simple, and it’s perfect for homes

They work well but there were no Instructions.

I really like these devices. They're small and very lightweight (they seem to consist of just a PC board and a speaker). Sound quality is really good. There's no battery option, but that would increase the size and weight. You can pick one of 6 channels if you want to be able to call a specific unit. Example: channel 1 for the kitchen, 2 for bedroom #1, 3 for bedroom #2, 4 for the garage, etc. Alternately, assign the same channel to all units so when you call, they all ring and the other person can answer wherever they are. You can monitor a room without being heard. My favorite feature is the two way communication. You can call another room, and when someone answers, you both can talk at the same time. It basically works as a speakerphone! It's better than VOX because unlike VOX, it does not cut out the first word (it does not have VOX). What I don't like is the sound volume. If someone is hard of hearing, they might have trouble. That's why I removed one star.
