Summer camp will not create an issue for claiming your child as a dependent. The camp would be considered a temporary absence for the residency test. You will consider the time spent at camp as time lived at home with you. See the following from IRS Publication 501:

Illness,
Education,
Business,
Vacation,
Military service, or
- Detention in a juvenile facility.

Camp

The cost of sending your child to a day camp may be a work-related expense, even if the camp specializes in a particular activity, such as computers or soccer.
