I know i sounds crazy with this unusual use of ip camera. I wnato put an array of 30x ip camera mounted on a ring, to shoot 360 degree photography of a human stand at center of the ring; that will be use for exhibitions. I am researching on which camera to use now. I choosed IP camera over other cameras like webcam, prosumer, dslr mainly bcs it's design to run 24/7 and I can program to retrieve the image over the HTTP API. I got a very affordable dlink DCS932L ip camera to test with. Everything went well except the image quality is not up to my requirements. I need something good enough to capture clear human face when he is in motion(such as jumping). Can someone help me by recommending a suitable brand and model pls?
