Field setup
Battery & power in the field
A camera is only as good as its power. What drains a battery fastest, and how to keep a grid running through a full season.
Cellular upload is the biggest single drain. Every photo or video a camera sends over 4G/LTE costs power, so a camera that uploads each trigger burns through cells far faster than one storing to an SD card. Match the upload frequency to how fresh the data needs to be.
Sending fewer, smarter frames is another way to stretch that budget — the idea behind the Smart Wildlife Box we're developing, where edge AI near the camera decides which frames are worth uploading.
Batteries
- Lithium AA — the field standard. They hold voltage in the cold, last longer, and don't leak like alkalines. Worth the cost for remote sites.
- Alkaline AA — cheap, but fade fast in the cold and under heavy cellular use. Fine for short, accessible deployments.
- Rechargeable / battery packs — an external pack or a larger cell extends run-time between visits; check the camera supports the voltage.
Solar
A small solar panel keeps a cellular camera topped up through the season, so you are not swapping cells every few weeks. In winter, or under heavy canopy, size the panel generously — short days and low sun cut what it can deliver.
Cold weather
Batteries lose capacity in the cold. Lithium handles it best; plan more spares in winter, and remember that a low battery is the most common reason a camera goes quiet mid-season.
Off-grid power
For a truly remote base — for example a Starlink dish serving several cameras — the dish itself draws roughly 50–75 W, so pair it with solar and a battery at that base station, not on every camera. More in Starlink & remote connectivity.
