Two-way audio on a hidden camera allows for real-time communication between the camera and a connected device, such as a smartphone or computer. The camera has a built-in microphone and speaker, and the user can hear what is happening in the camera’s environment and can also speak through the device to communicate with whoever is in the camera’s view. This can be helpful for monitoring and communicating with pets, children, or elderly relatives.
To use two-way audio, the user typically needs to download a mobile app or access a website associated with the camera, and connect the camera to their Wi-Fi network. Some cameras also allow for voice activation, so the user can speak to the camera without needing to manually access the app or website.
