Video camera for snake hunting

I'm looking for a GoPro-like camera to take with me on hikes in hopes of capturing an endangered snake on video. Key features are at

least 1 hour of battery life and storage, more is better, a lens that's sufficient to accurately the species of the camera is attached to my

body (resolution and FOV at roughly 6-20' distances) and a sensor high res and with sufficient color rendering to see detail and color at

that same distance. Any thoughts are appreciated. Anything under $500 is fine.
