Camera traps for motion-triggered or continuous time-lapse recordings are readily available on the market. For demanding applications in ecology and environmental sciences, however, commercial systems often lack flexibility to freely adjust recording time intervals, suffer from mechanical component wear, and can be difficult to combine with auxiliary sensors such as GPS, weather stations, or light sensors. We present a robust time-lapse camera system that has been operating continuously since 2013 under the harsh climatic conditions of the Antarctic and Subantarctic regions. Thus far, we have recorded over one million images with individual cameras. The system consumes 122 mW of power in standby mode and captures up to 200,000 high-resolution (16 MPix) images without maintenance such as battery or image memory replacement. It offers time-lapse intervals between 2 s and 1 h, low-light or night-time power saving, and data logging capabilities for additional inputs such as GPS and weather data.
用于运动触发或连续延时录制的相机陷阱在市场上很容易买到。然而，对于生态和环境科学中的高要求应用，商业系统往往缺乏自由调整录制时间间隔的灵活性，存在机械部件磨损问题，并且可能难以与GPS、气象站或光传感器等辅助传感器结合使用。我们展示了一种强大的延时相机系统，自2013年以来一直在南极和亚南极地区恶劣的气候条件下持续运行。到目前为止，我们用单个相机已经记录了超过100万张图像。该系统在待机模式下功耗为122毫瓦，无需进行诸如更换电池或图像内存等维护即可捕获多达20万张高分辨率（1600万像素）图像。它提供2秒至1小时的延时间隔、低光或夜间节能功能，以及用于GPS和气象数据等额外输入的数据记录功能。
