The VTech DM112-2 PU Digital Audio Baby Monitor in White offers parents peace of mind through its voice monitoring capabilities. This baby monitor, with a frequency of 2.4GHz (WiFi), is portable and includes a lullaby feature to help soothe your little one back to sleep. The digital display allows for easy monitoring, making it a convenient choice for keeping your baby safe and healthy.

As shown in the photos these power on and make noise so they work.

Please let me know if you have any questions.

Thanks
