We have loved our levana astra monitor for DD1 (2.5). The best part is the vox or peep mode where the screen stays black and the sound stays off until there is noise above a certain volume in her room.

DD2 is due in 6 weeks.

Is it possible to replicate the vox/peep with one monitor and 2 cameras, or will we be forced to either choose a room for peep mode or have the cameras scan each room?
