The battery life of a hidden camera with time lapse can vary depending on the quality of the battery and the frequency of recording. Typically, these cameras can last anywhere from a few hours to a few days. It is important to consider the battery life when purchasing a camera with time lapse, as you don’t want to miss any important footage due to a dead battery.
To extend the battery life of a hidden camera, it is recommended to use a high-quality battery and reduce the frequency of recording. Some models may also have the option to use an external power source, such as a power bank or an AC adapter, which can provide continuous power to the camera. Additionally, turning off any unnecessary features such as Wi-Fi connectivity or motion detection can help to save battery life.
