Scho63 asked me what kind of camera I use. I have a Nikon Coolpix I've used in years past, but lately I've been using a Panasonic Lumix DMC-FZ7 that I bought on Craigslist from a guy a couple years ago. It's a 2007 model, in 2007 it was about a $400 camera. Not as pricey as a higher end Canon or Nikon, but it does a good job. It's also small so it fits the "camera bag requirements" through security. And the Chiefs won't allow "professional equipment" for photo or video unless you're with the media. This camera has auto zoom and auto focus, and just does a nice job, I've been very happy with it. I think I paid about $150 for it in 2010.
