i second the 12 volt kit. you really have to get one it will save a lot of money in the long run. probably want 2 batteries so you can swap them out when you check the cam.it's a little more money up front but it's definitely worth it. I've now tried every single major brand and the only one I'm happy w/ is wildview, it's the only digital cam I've ever purchased that I thought was worth the money.
