Does the camera have sound and video?
Live streaming has both sound and vision.
Each camera has both a built-in speaker and microphone for full duplex, 2 way audio.
You can hear and talk effortlessly via the Moobox app.
So not only will you be able to hear audio when viewing Live but you can talk back, via the app, to whoever is at the other end of the camera to. Be mindful the person at the camera end has to be close to the camera to hear you, of course.
PIR triggered clips saved to the hub and Cloud are video only currently. This helps keep the file sizes manageable for quick recording, upload and storage.
