The solar panels charge the built-in battery while sunlight is available. If the camera's current operation uses more power than the solar panel can provide, the battery level will reduce.These 2 factors may influence the experience: 1. The solar panels are not charging the device enough. One possibility is that the position of the camera is not allowing enough access to direct sunlight. In this case, adjust the position or location. It may also be that the weather is not ideal for solar charging. In this case, there is no need to worry. When the weather becomes sunny, normal charging will resume.2. The current operation of the camera is consuming power beyond what is normal. In this situation, you may need to adjust the configuration to reduce false triggers and excessive recording events. Try the following:1) Switch to Power Saving mode.2) Reduce the sensitivity of Motion Detection.3) Choose Human Only mode.4) Enable Activity Zones that focus on the monitoring area. Try to avoid including public walkways or roads as movement in these areas may result in frequent false triggers.
