Throwing Cameras

Short Range Throwing Camera
What to know what is going on around the corner? Then you can use a "throwing camera". This is a weighted ball containing a video camera, a motor and a radio transmitter. You throw the ball into a room and it rights itself so the camera points horizontally. The motor then rotates the camera so that it takes a panorama of the room and transmits the picture back to you.

These units seem to be little more than a low cost security camera, motor and an analog radio transmitter. Something better could be built from a web camera and WiFi digital transmitter, but perhaps not at a throwaway price.

These are made for the military and for law enforcement by MACROSWISS (Short Range Throwing Camera) and the Remington (i Eye Ball R1):
The Short Range Throwing Camera (SRTC) is a hand-thrown remote observation system and has been designed to continuously broadcast a panoramic view of the surrounding area to a remote receiver.

This product is able to sustain the impact when thrown or launched from a significant distance. ...

The unit is roughly the shape of a ball and is split into two halves. When deployed the top half rotates with respect to the base.

The bottom of the unit is flat. The weight of the unit has been specifically distributed so that it will automatically right itself so that the flat base is on the ground, regardless of the starting position.

The upper part of the unit contains a camera and a motor. When turned on, the motor causes the upper part of the SRTC to rotate, giving the camera a panoramic view of the surrounding area. A micro-transmitter then broadcasts the video signal up to 300m.
