Generally, a Smartphone and Facebook live is the easiest and cheapest (free, outside of any data plan limitations) option.
Thanks Josh. We are going with this option (on a LynkSpyder) and it's working well. We did overheat once (in March, yikes) so have some worry about the summer. I can try the cold towel in a zip lock bag, draped over the screen I suppose. Thanks for the tip.
