CBZ files are very similar to .CBR files, the only difference being that .CBR files are compressed using .RAR compressing. CBZ files contain either.

Essentially, a PTZ camera is set in a particular place, but has the ability to turn, usually in a complete circle, tilt at different angles both up and down, and zoom in on particular objects.TZ, or pan, tilt and zoom cameras can make a 360-degree sweep of the environment, change angles to look at objects both above and below the camera, and zoom in to give objects greater detail. These cameras are used most often in surveillance situations where remote viewers can track subjects.
