The first generation of Digital HERO cameras (2006–09) were powered by conventional AAA batteries and included a rugged housing and wrist strap. Models were distinguished by their still image resolution and shot video in standard definition (480 lines or lower) with a 4:3 aspect ratio. Like the film camera HERO, the first-generation Digital HERO cameras were equipped with an optical viewfinder.
The original Digital HERO (DH1; 640×480 still resolution, 240p video in 10-second clips) of 2006 was succeeded by the Digital HERO3 (DH3; 3-megapixel stills, 384p video) and Digital HERO5 (DH5; same as DH3 but with 5-megapixel stills). All three of these had a 54° angle of view. A variant of the DH5 was released with an extreme wide-angle lens with 170° of angular coverage on the diagonal as the Wide HERO; the Wide HERO had a different housing than the other first-gen cameras (DH1/DH3/DH5) to accommodate its larger lens.
The Digital HERO released in 2006 (Model: SQ907 mini-cam) had a 640×480 camera and shot QVGA definition 320×240 (10 fps) video for a maximum of 10 seconds. The Digital HERO1 had 32 MB internal memory without SD slot.
