General Overview
The time-lapsed cloud video (TLCV) camera provides a record of sky conditions by recording color images of an approximately 100-degree field of view, centered on the zenith. The time interval between images may be adjusted to a wide range of periods, but typically is set to 4 or 8 seconds, thus providing a high time resolution record of cloud conditions. Data is stored to S-VHS tape for archival.
