After many requests we are happy to inform you that we can offer our customers who buy photobooth a wireless buzzer at last. We produce the buzzer for our photobooth ourselves and it perfectly acts in concert with the DSLR booth. Activating the buzzer triggers a page-up command which leads to the start of the countdown. The photobooth buzzer is also compatible with other photobooth software, provided that a page-up command to initiate the software can be adjusted. Also, when you buy photobooth the buzzer features a control LED to assert whether the batteries are still full. The photobooth buzzer is operated with 2 AAA batteries (included in delivery when you buy photobooth). The receiver is a small memory stick.
