Thank you for your question AnonymousII. One way communication means that you can hear sound on the DVR if you have a microphone and speaker connected. While we don't offer audio recording devices, there are many out there with the necessary RCA connections! Thank you for considering Defender to give you the peace of mind you deserve!
Sorry, there was a problem. Please try again later.
