Such a useful multi-purpose gadget at an affordable price! Easy as 1, 2, & 3... Just insert SD card (not included), set recording mode, and plug in to start recording! Keep an eye on your most valuable things at all times while also having the ability to charge 2 phones, tablets, or any USB device! Make sure family, friends, and expensive items are safe with this combination Security Camera and Dual USB charger. Insert up to 32GB SD card and set the camera to record continuously or only when it senses motion for about 8 hours of footage. The best part is that if you run out of storage, it will over-write the oldest clips, so you don't have to worry about constantly cleaning off old useless footage! The 8 infrared sensors also help monitor up to 3 meters in low light. *In compliance with federal law 18 U.S Code Chapter 119 and Amazon policy, this camera does not have audio capabilities.*
