With some exceptions - college-specific ID camps are primarily a way for the program and their assistant coaches to earn extra money in the offseason. Not to say that players can’t be identified at these camps but this is the exception rather than the rule.
For me - the best ID camp (the one I reference above where we spoke with the ACC coach) is EXACT ID. Google it, do your own research and gauge for yourself as to whether it’s a good opportunity for your daughter but for our family - it was worth every penny. They have 1- and multi-day options and have multiple events throughout the year, featuring coaches from D1, D2 & D3 progams.
Aside from the standard training and games most camps have, there’s a lot of required pre-camp homework. For example - they require the players email coaches who’ll be in attendance prior to camp to give them practice reaching out to coaches. They have each player rehearse an elevator speech and then pitch themselves to every coach in attendance to give them experience and confidence to approach coaches at tournaments they might attend in the future. They’ll also assign a coach to your player who will work with them at various points during the day and provide a written and recorded oral evaluation that our daughter received the day after the camp was held (Assistant coach from a Big 10 program gave the eval for our daughter, so legitimate coaches/not just a Freshman staying at college during the off-season).
Lastly - they have Q&A panel sessions for parents with the coaches re: the recruiting process, what they look for at various divisions, etc
Strong recommend from my perspective. Learned a ton.
PS - agree with @twoinanddone - ability to play a club sport provides no advantage in admissions
