Use a compact, sealed frame made of carbon‑fiber or aluminum alloy, and cover it with a weather‑sealed gasket that keeps out wind and ice. Mount the camera on a tripod head that locks into place when the wind hits it; a simple, manual lock is lighter than an electric one. Power the whole thing with a high‑capacity Li‑ion pack wired to a low‑draw micro‑controller that turns the camera on only when a motion sensor trips. Keep the camera’s ISO high and use a fast lens, so you need less light and fewer shots. Add a small, insulated sleeve to the battery pack to keep it from freezing. That should keep the rig alive through a blizzard and let you catch a snow leopard without draining the batteries too fast.
