Thanks to the 40m waterproof and shockproof casing and host of mounts the GoPro HD Hero4 Silver can be attached to a number of surfaces, and adapted via optional accessories, with the rear touchscreen providing a framing and control method.

The GoPro HD Hero4 Silver offers a 12MP sensor for capturing stills, making it possible to create A4 prints from the results. Stills can be taken at intervals, for up to 30 seconds, or triggered to take up to 10 photos in 1 second. The video mode is capable of recording 1080p and 720p movies at a variety of frame rates including 60fps for slow-motion, or at 4k for extremely high resolution movies. The wide angle of view, which offers a similar perspective to a fisheye lens on a DSLR, can be narrowed where necessary, and the Wifi is able to communicate with a smartphone as a remote or a bespoke GoPro remote. With the addition of the touchscreen and Bluetooth connectivity, the GoPro HD Hero4 Silver makes some significant gains over the previous GoPro HD Hero 3+, making it a worthwhile choice for a serious sportsperson.
