We installed NPC 940mm IR Trail Camera at the Haunted Quarry Mines, Mussoorie, India. We are very assured that there was no one in the premises when suddenly a smoke appeared in the middle of the screen and climbed up the wall and then a heavy breathing was captured on audio. A trail camera captures video and pictures instantly on sensing any slight motion. Usually it does not captures fog and smoke unless it is very heavy. We were still skeptical until we heard that Sigh! Appears to be a sad spirit.
