Abstract: A recording system may include a camera configured to record images including a first image and a storage device configured to store the images. The recording system may include a controller configured to identify at least one vertical line contained in the first image and determine whether the first image is indicative of a probable event area based on the identification of the at least one vertical line. The controller may be configured to command the camera to record the images at a first quality if the first image is indicative of a probable event area. The controller may also be configured to command the camera to record images at a second quality if the first image is not indicative of a probable event area. The images recorded at the second quality occupy less memory in the storage device than the images recorded at the first quality.
