Spy Electronics For Firefighters Or Electronics Experts?

For Firefighters or electronics experts? - spy electronics

I wonder if anyone knows a relatively low cost mini (spy) camera can be connected to a helmet and are held in areas with high temperature. I would like to be considered a wireless camera to connect to my headset structure of the test fire or burn videos for training after the fact to be found. So, anyone know if the little mini-camera that Wal-Mart has a job. At a price of only $ 70 it would be the loss of an important, if not more work, but I know a futile from the start, not even trying.
