Camera trapping is a capture-recapture technique used to document the presence of warm-blooded wild animals. Infrared cameras are set up in the field and take photos whenever an animal passes in front of the camera. The cameras can identify individual tigers based on their unique stripe patterns. Camera traps are also effective for surveying small carnivores. Sites are selected after a reconnaissance survey to identify potential animal activity areas. Digital cameras with infrared and motion sensors are used and placed at heights of 30-40cm apart from each other. The cameras remain active for 10-20 days at each station to photograph animals and record the date and time.
