Use a ReoLink E1 &/ E1 Zoom as VoiceAssist with WakeWord?

Hello,

i just started my Home Assistant Journey and ordered three ReoLink Cameras. Two E1 and one E1 Zoom. All of them will be indoor.

Now i also installed and configured the local voice pipeline with piper and whisper and it works great with my companion app.

Is it possible to use the two-way audio of those cameras for voice assist with wakeword?
If yes, how would it be with multiple devices in hearing-range picking up the wakeword? Will only the loudest be picked and while talking to it disable the others?
