Yep, as others have stated, it's illegal to bait deer in New York state. So, if you're placing corn at trail cams, you're in violation of the regulations. I wouldn't exactly be surprised if the penalties are stiff in NY.

Deer and Moose Feeding Regulations
What are the restrictions on deer and moose feeding?
Part 189 of Title 6 of the Codes, Rules and Regulations of the State of New York was last amended on July 28, 2010. Part of this rule restricts the feeding of deer and moose.
In New York, it is illegal to feed deer and moose by putting out any material that attracts them to feed.
There are five exceptions to the rule:
1. Agricultural crops including wildlife food plots.
2. Distribution of food to livestock.
3. Distribution of food to captive deer and elk.
4. Cutting of trees and brush.
5. Scientific research, wildlife damage abatement, and wildlife population reduction programs, but only under a permit issued by DEC.
