One high-resolution image from each camera is stored each second, 24x7. To help navigate through hundreds of thousands of images, images are stored in epochs of ten seconds for seven days. Within each epoch, each camera has its own directory of image files. The following link allows you to pick an epoch, and then a camera. You may then view the 600 images for that camera as a slide show. Remember, the images are just jpg photos, so if you see an image you like, simply right-click and save-image-as to get a copy of the image.
