high quality...two way audio ... camera controlled from the remote ..video on the remote can be turned off so you only have audio ... remote has a belt clip ...the camera has a very sensitive microphone and night vision in pitch black .. remote and camera can be powered from a normal USB socket as well as the charges provided ...works very well...hold the power button for a few seconds for on and off or a quick push adjusts the remote brightness..the remote can be muted for visual sound monitoring only via a coloured led bar ...has a decent range and the battery is replaceable in the remote ...not new and not mint ...it's a used item that works great ....thanks for looking
