High Resolution Video Quality Captures Audio/Video Even In Low Light
About the size of a pack of gum, this miniature camcorder is perfect for covert operations on-the-move. Completely battery powered and self-contained, this camera with a built-in DVR can capture up to 3.2 hours of video with a 8Gb SD card (not included). One-touch or sound activated recording makes it easy to capture any important moments, on-the-fly. What makes this camera different is even though it's tiny, it can still capture high resolution 640 x 480 video, much like full sized professional cameras. With such high resolution video, you can be sure to capture every detail even in low light situations.
