Audio and video communication features are critical for door phones and surveillance systems as they ensure clear interaction between visitors and residents. The best systems offer high-definition video and audio, with noise reduction and echo cancellation for clarity. Options range from full-duplex communication to integrated HD cameras with night vision. For example, the Fanvil i61 offers HD voice and a built-in HD camera, while the Fanvil i64 combines HD video with acoustic noise cancellation. Different models, like the Fanvil i32V, also offer dual video streams for enhanced monitoring and communication.
