Guys , to answer to all your question.
This a young male tiger hence may be looking small , also lens used here is wide angle 11-16mm Tokina at 11mm focal length that may also giving a smaller size effect.

Yes , no stealing of camera. This place doesn't come under Corbett area , it's in a periphery and one is allowed to put cameratrap. No human movement also it is dangerous to move around in day or night.
We used to move around in a group of 3-4 people.

More danger is from elephant not from tiger. Once my camera was kicked 20" ft down in a valley by an elephant.
Shall soon post some more images.
