Using Two-Way Audio
Live communication with two-way audio requires your camera to have a built-in microphone.
Navigate to Live View and double-tap camera to fullscreen
Press and hold the microphone icon (lower right corner)
Speak naturally - record up to 10 seconds and release to broadcast
Listen for return audio from on-site microphone
Tip: The camera must be fullscreen and have a built-in microphone to hear audio from site. Without a microphone, your audio broadcasts but you cannot hear responses.
Using Pre-Recorded Messages
Pre-recorded audio works on any camera without a microphone requirement.
Go to Live View and double-tap your camera to fullscreen
Tap the speaker icon to broadcast pre-recorded message
Audio plays through connected speaker/PA system automatically
