NEW Bullet HD 1080p Helmet Camera Waterproof Fireproof DVR 12MP Photo Video, Audio, and Stills: The BulletCam 2.0 packs a ton of features into a compact body. A durable, glass fisheye lens captures a wide field of view, taking both video and still photos at your discretion. Plus, a built-in microphone supplements your stunts with audio, so youll still hear the cheers of your friends (or fans) every time you play it back. Powerful and Efficient Battery: The BulletCam 2.0s rechargeable lithium-ion battery holds enough power to record continuously for 3 straight hours. Small and Lightweight: The sleek cylindrical body measures only 4x1-inches and weighs only a few ounces, so whether you strap it to your Helmet, Ski Pole, Snowboard, Surfboard, Kayak Paddle, Mountain Bike, or elsewhere, it never gets in the way. Intelligent, Responsive Technology: Focus on the thrill, not on recording it. The BulletCam 2.0 builds in a range of automatic features that work behind the scenes to make sure your video is perfect. This includes automatic white balancing, digital video motion stabilization technology, and three options for exposure control: center-focused, spot-focused, and of course, auto. Plus, all footage includes a watermark so you can quickly recall exactly when your feats took place. Universal Formats for Easy Uploading: Video is recorded in H.264/MPEG-4 format, which is compatible with any operating system and accepted in every common video editing software. Ultra Hi-Performance MicroSD cards up to 64GB store your videos. We recommend you use MicroSD Class 6 or above for optimal performance. USB cables charge your battery and communicate directly with any Mac or Windows computer without additional formatting.
