How long does the battery last on a small or tiny surveillance camera?

The battery life mini spy cameras can vary depending on the model and usage. Some devices can last for several hours while others may last only for 30 minutes. It’s important to note that using advanced features such as night vision or motion detection can significantly reduce the battery life of the camera. If you plan to use the camera for extended periods of time, it may be necessary to have spare batteries or to use an external power source.
