I too am very interested in building my own mirror photobooth as the prices of ready made ones are crazy high… and the shipping cost to my country is ridiculous…:flag_my: however after tons of research i think the biggest problem now is are we able to calibrate/ adjust the borders of the IR overlay on the mirror? one of the features of the mirror photobooth is that users can “sign” their name/ message (hence the use of touchscreen on a two way mirror); but the TV screen behind the mirror is smaller than the mirror itself (43" TV under a 70" mirror), so are there any way to reduce/ calibrate the IR overlay to precisely detect the TV screen?
