Image:
‧Image frame rate: up to 30 (25) frames/second.
‧Supports two compression modes, the Motion - JPEG and the MPEG4.
‧5 levels of compression provided. The file size of an M-JPEG compressed
image depends on the image’s actual content. Images with a lot of detail will
generate bigger files. The level of compression determines the image quality.
High compression requires smaller files while low compression gives you finer
image quality along with bigger files. The table below contains the average file
size in Kbytes, derived from real life tests.
