The UK’s Ministry of Defence is currently working on a ’Grenade Cam’ device dubbed the "I-Ball" for use by UK troops on the battlefield. The said device is meant to be fired from a grenade launcher into hostile territory, then relaying back a 360-degree view of the battlefield wirelessly.

Inside the camera are image sensors and two fish-eye lenses would enable the device to help soldiers be more informed of hazardous areas or in hostile urban environments.
