No audio recording. This is a full-hidden nanny cam for home security with HD video quality and a perfect hidden appearance. The 10mm large usb spy camera lens and powerful 940nm night vision light beads allow you to enjoy the immersive feeling no matter day or night. While using a more stable and easy to connect APP, all video content is encrypted on this small security camera and can only be viewed through the mobile app. Even if it is discovered during use and the memory card is removed, it will not leak any information. It's the best secret camera for the home. * You can contact us for an exclusive video player to playback the videos on your computer.
