Network Settings Network Requirements (continued) Bit Rate of Audio Only 1 audio data stream can be received. Data volume for 1 audio stream is 64 kbps. Audio data volume may be calculated using the following formula. 64 kbps x no. of streams The number of streams is the total number of streams sent via TCP (number of clients), streams sent via multicast, and stream received by camera (Example) When camera sends out 2 audio streams and receives 1 audio stream, data volume will be as follows. 64 kbps x 3 = 192 kbps Restrictions on the Number of Distributions for camera The maximum number of distributions for camera is determined by the settings as well as requirements from the client. For JPEG distribution, you can select either "Frame Rate Priority" mode or "Client number Priority" mode. "Frame Rate Priority" mode distributes JPEG images according to the frame rate requested by the client. The maximum number of distributions is determined based on the highest bit rate within the distribution streams. For "Client number Priority" mode, if there are requests from multiple clients, JPEG images are distributed in a lower frame rate than that requested to cater to multiple clients. It can accept 20 distribution requests as the maximum number of clients. Ⅵ When Frame Rate Priority Mode is Selected JPEG images are distributed at the frame rate requested by the client. When a distribution request that exceeds the maximum number of distributions is received, this request is denied. ● When only JPEG images are distributed For example, if Client A requests for JPEG at 1 Mbps, while Client B requests for JPEG at 5 Mbps, additional 2 streams (total 4 streams) of distribution are possible for request below 5 Mbps. Maximum number of distributions when only JPEG data is distributed Distribution Maximum Total at maximum number of maximum bit bit rate distributions rate 1 Mbps and 20 below 20 Mbps 5 Mbps and 4 below 20 Mbps 10 Mbps and 2 below 20 Mbps Larger than 1 10 Mbps Maximum configurable value (24 Mbps) 4 ● When both JPEG and MPEG4 images are distributed When both JPEG and MPEG4 images are distributed simultaneously, distribution up to two clients for JPEG and three clients for MPEG4 respectively is possible. However, distribution requests that exceed a total bit rate of 20 Mbps will be denied. Maximum number of distributions when JPEG and MPEG4 data is distributed Maximum number Maximum number of distributions of distributions for for JPEG MPEG4 Total bit rate 2 3 20 Mbps and below ● When only MPEG4 images are distributed The maximum number of distributions is determined by the preset bit rate. When a distribution request that exceeds the maximum number of distributions is received, this request is denied. When distributing only MPEG4 data Preset bit rate Maximum number of distributions Total maximum bit rate 0.6 Mbps and 20 below 12 Mbps 3 Mbps and 4 below 12 Mbps 4 Mbps and 3 below 12 Mbps 6 Mbps and 2 below 12 Mbps Larger than 1 6 Mbps Maximum configurable value (8 Mbps) Ⅵ When Client number Priority Mode is Selected ● When only JPEG images are distributed If the distribution request would be accepted in the frame rate priority mode, distribution works in the same way as frame rate priority mode, where JPEG images are distributed at the frame rate requested by the client. If the distribution request would be denied in the frame rate priority mode, the frame rate is controlled such that the maximum bit rate is as shown in the following table, to accept distribution requests from up to 20 clients. For example, if Client A and B request for JPEG at 10 Mbps, and Client C requests for JPEG at 5 Mbps, the frame rate will be reduced such that the distribution bit rate to each client is less than 5 Mbps. Maximum bit rate when only JPEG data is distributed Current number of Maximum bit rate Total maximum bit distributions rate 2 and below 10 Mbps 20 Mbps 3 to 4 5 Mbps 20 Mbps 5 to 20 1 Mbps 20 Mbps
