The timeline for how long a camera system will last can vary depending on a variety of factors. The environment the cameras are installed in and how often they are used have a major impact on their longevity. For example, cameras that are constantly exposed to extreme temperatures or moisture may not last as long as those kept in more moderate conditions. Additionally, if the camera is used frequently, it could wear down much faster than one that is rarely used. To ensure your camera system lasts as long as possible, it's important to consider these environmental elements and usage patterns when making your purchase decision.
