46AXIS 214 PTZImportant!•The figures displayed here are the values as delivered by the camera. If other restrictions are currently in force,(e.g. bandwidth limitation) these values might not correspond to those actually received by the client.•For Motion JPEG, these values will only be accurate as long as no frame rate limit has been specified.Frame rates - Motion JPEGThe following test results show the frame rates in frames/second (fps) for Motion JPEG streams from theAXIS 214 PTZ, using a compression level of 50%. Note that these values are guidelines only - actual valuesmay vary.Frame rates - MPEG-4The following test results show the frame rates in frames/second (fps) for MPEG-4 streams from the AXIS214 PTZ. Note that these values are guidelines only - actual values may vary.The MPEG-4 test conditions:• Compression level = 50%• Video Object Type = Advanced Simple• GOV structure = IP*.*Note that setting the GOV structure to use “I-frames only” will increase the frame rate.BandwidthAs there are many factors affecting bandwidth, it is very difficult to predict the required amounts. Thesettings that affect bandwidth are:• the image resolution• the image compression• the frame rate• the MPEG-4 object type• the MPEG-4 GOV structure• the audio settings.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 important than the imagequality, using a constant bit rate (CBR) is recommended. Use a variable bit rate (VBR) if the image qualityneeds to be maintained at a higher level. If supported on the network, consider also using MPEG-4multicasting, as the bandwidth consumption will be much lower.fps4CIF 25/302CIF expanded 25/302CIF 25/30CIF 25/30QCIF 25/30fps4CIF 17/212CIF expanded 17/212CIF 25/30CIF 25/30QCIF 25/30
