of professional low-sensitivity external microphones. The video modes supported by the HERO4 Silver Edition are similar to those of the HERO3+ Black, due to the higher processing speed and thermal requirements of encoding 4K video (3840×2160), but it supports Wi-Fi, Bluetooth and contains the same Ambarella Inc. A9 system on a chip (SoC) as in the HERO4 Black. The HERO4 models maintain the H.264 video codec of previous versions and MP4 file formats. GoPro claims the mono microphone in both the Black and Silver Editions has twice the dynamic range of that in the HERO3+, and that the HERO4 Black and Silver Editions have improved low-light performance. HERO (2014) In September 2014, GoPro released an entry level camera named simply "HERO", priced at $130, alongside the HERO4 Black and HERO4 Silver. It is built into a waterproof housing, unlike the HERO4 line. The GoPro HERO (2014) can capture 5mp still images and has a 5fps burst option. It is able to record 1080P at 30 or 25fps and 720P at 60 or 50fps on to a MicroSD card up to 32GB. It has an LCD non touch display on the front and is waterproof down to 40m. HERO+LCD In June 2015, the company started to sell the GoPro HERO+LCD, which provides video recording at 1080p at 60 fps and 8 megapixel photos. The HERO+LCD is also built into a waterproof housing. GoPro HERO+LCD has a touchscreen to preview the shot to frame the scene and letting the user navigate the menu. A new feature in the camera was instant camera editing. GoPro HERO+LCD is waterproof, because it is built directly into a waterproof case (waterproof to 131 feet (40 m)). The device also includes a feature HiLight Tagging and built-in video editing function, which allows the user to put a label on the main points while shooting video or in the process of view, which makes it possible to quickly find desired footage later. It also has built-in Wi-Fi and Bluetooth, and user-friendly modes like QuikCapture, SuperView and Auto Low Light. HERO Session The HERO Session, released July 6, 2015, is 50% smaller and 40% lighter compared to other versions of the GoPro HERO4 camera. HERO+ In October 2015, GoPro released its third entry level camera: GoPro HERO+. This camera is the same as the previous HERO+LCD with its 1080p 60 fps / 720p 60 fps video resolution, 8 MP
