In this paper, a disaster surveillance video transmission system by wireless ballooned network is proposed to promptly observe and grasp the information around the disaster area form sky on the occurrence of disaster. A combination of both omni-directional camera and pan-tile-zoomed control camera so called PTZ camera is used to widely capture images with 360 degree direction by omni-directional camera while the specified point in the omni-directional camera image is panned, tilted and zoomed using PTZ camera. Using ballooned surveillance video system, video image in the large area in the disaster place where human being cannot approach is covered from sky. A prototype system is constructed to evaluate its function and performance through omni-directional video surveillance system. As we result, we verified the usefulness of the proposed surveillance video transmission system.
