57AXIS 210A/211A - Technical SpecificationsFrame rates - Motion JPEG and MPEG-4The following table show typical frame rates in frames/second (fps) for Motion JPEG andMPEG-4 video streams from the AXIS 210A/211A.Note that these values are guidelines only - actual values may vary.Motion JPEG settings:• Viewing in AMC• Compression level = 30%MPEG-4 settings:• Viewing in AMC• Compression level = 30%• Video Object Type = Advanced Simple• GOV length = 8• GOV structure = IP*Note: Setting the GOV structure to use “I-frames only” will increase the frame rate at the expense of the bit rate.BandwidthAs there are many factors that affect bandwidth, it is very difficult to predict the requiredamounts. The settings that affect bandwidth are:• the image resolution• the image compression• the frame rate• the MPEG-4 object type• the MPEG-4 GOV structure• the maximum exposure time.There are also factors in the monitored scene that will affect the bandwidth. These are:• the amount of motion• the image’s complexity• the lighting conditions.For MPEG-4, if there is only limited bandwidth available, and if this is more importantthan the image quality, using a constant bit rate (CBR) is recommended. Use a variable bitrate (VBR) if the image quality needs to be maintained at a higher level. If supported on thenetwork, consider also using MPEG-4 multicasting, as the bandwidth consumption will bemuch lower.Frame ratesMotion JPEG MPEG-4640x480 30 25480x360 30 30320x240 30 30160x120 30 30 |
