You can attach the camera to your baby's clothes or use the included tripod mount to attach it to the crib. The Babeyes camera doesn't have WiFi or bluetooth and doesn't connect to the internet. This means that there aren't any radio waves coming from it and that the videos remain private.

Babeyes has a motion detect sensor to automatically trigger a 720p HD video recording. Each video clip lasts 20 seconds. Babeyes claims the battery-life is 5 hours when in standby mode or 2 hours when recording videos.
