Portable hidden cameras can be used outdoors, but most of them are not waterproof and should not be used outside for extended periods unsupervised. If you need to use your camera outside it’s important to make sure they are weatherproof or housed in a protective enclosure to prevent damage from rain, wind, and other environmental factors.
Prolonged outdoor use may also require additional power options, such as solar or battery-powered systems, to ensure the camera stays operational in remote locations without access to electrical outlets.
