These days they generally use SD cards or micro SD Cards. If the sensitivity is set it should only record when something is moving. While Wi-Fi cameras aren’t even as close to being as good as wired ones, it’s amazing how much battery life modern surveillance cameras can get. The ones with big lithium batteries can go for weeks or even months Without a change.
for those looking for night time cameras, something to keep in mind the “sensor” size is EVeRYtHING, not how many megapixels is it. I’m not an expert but it’s a topic I enjoy.

trail cameras work but a surveillance system like addy mentioned Will probably have options with bigger sensors
