Unseen areas are troublesome for police, but now Bounce Imaging is providing both officers and rescuers a safe glimpse of the unknown areas through its new grenade-sized sphere full of cameras.

'Camera in the hole!' might be the new phrase police shout, as they toss the new Explorer camera orb into a dangerous room before entering.

The Explorer is a small, grenade-sized sphere full of cameras that first responders can throw into a space to get a preliminary view, MIT News states.

As per makers of the Explorer, when remotely activated, it assembles a panoramic image of what is inside a particular area.

The rubber ball has a camera inside with six lenses to capture the scene inside a room and would then create a 360-degree panorama every second for their 30 minutes of run-time and transmit those photos remotely to a tablet or a smartphone.

According to Bounce Imaging, the Explorer works both with Android and iOS. It is priced a little under $2,500 and uses a near-infrared LED.

On the other hand, a basic version, targeted towards normal consumers, would sell for about $1,500 and uses white LED lights to illuminate a room.

It has been said that Explorer provides a unique advantage over the previous device that was used by first responders, allowing it to be used for special purposes.

It would also allow police to identify the positions of hostile gunmen or provide an alternative to flashbangs so that they don't accidentally kill anyone.
