Updated Information (1) Very occasionally, MPEG-4 streaming can stop for about 1 second when framerate is low and bitrate is high. (2) Client Number Priority mode for JPEG distribution 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. - 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 at maximum bit rate |Maximum number of distribution | Total maximum bit rate | |---------------------------------|-------------------------------|------------------------------------| | 1 Mbps and below | 20 | 20 Mbps | |---------------------------------|-------------------------------|------------------------------------| | 5 Mbps and below | 4 | 20 Mbps | |---------------------------------|-------------------------------|------------------------------------| | 10 Mbps and below | 2 | 20 Mbps | |---------------------------------|-------------------------------|------------------------------------| | Larger than 10 Mbps | 1 |Maximum configurable value(24 Mbps) | |---------------------------------|-------------------------------|------------------------------------| * When both JPEG and MPEG-4 images are distributed When both JPEG and MPEG-4 images are distributed simultaneously, distribution up to two clients for JPEG and three clients for MPEG-4 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 MPEG-4 data is distributed |-----------------------------------------|-------------------------------------------|------------------| |Maximum number of distributions for JPEG |Maximum number of distributions for MPEG-4 | Total bit rate | |-----------------------------------------|-------------------------------------------|------------------| | 2 | 3 |20 Mbps and below | |-----------------------------------------|-------------------------------------------|------------------| * When only MPEG-4 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 MPEG-4 data |-------------------|--------------------------------|-----------------------------------| | Preset bit rate |Maximum number of distributions | Total maximum bit rate | |-------------------|--------------------------------|-----------------------------------| |0.6 Mbps and below | 20 | 12 Mbps | |-------------------|--------------------------------|-----------------------------------| |3 Mbps and below | 4 | 12 Mbps | |-------------------|--------------------------------|-----------------------------------| |4 Mbps and below | 3 | 12 Mbps | |-------------------|--------------------------------|-----------------------------------| |6 Mbps and below | 2 | 12 Mbps | |-------------------|--------------------------------|-----------------------------------| |Larger than 6 Mbps | 1 |Maximum configurable value(8 Mbps) | |-------------------|--------------------------------|-----------------------------------| - 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 client. For example, if Client A and B request for 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 distribution |Maximum bit rate |Total maximum bit rate | |-------------------------------|-----------------|-----------------------| | 2 and below | 10 Mbps | 20 Mbps | |-------------------------------|-----------------|-----------------------| | 3 to 4 | 5 Mbps | 20 Mbps | |-------------------------------|-----------------|-----------------------| | 5 to 20 | 1 Mbps | 20 Mbps | |-------------------------------|-----------------|-----------------------| * When both JPEG and MPEG-4 images are distributed When both JPEG and MPEG-4 images are distributed, distribution works in the same way as frame rate priority mode if the distribution request would be accepted in the frame rate priority mode. 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 for up to a total number of 20 JPEG and MPEG-4 distributions. However, distribution requests for which the total bit rate of the MPEG-4 distribution stream exceeds 10 Mbps will be denied. Maximum JPEG bit rate when JPEG and MPEG-4 data is distributed |--------------------------------|-----------------|-----------------------| |Current number of distributions |Maximum bit rate |Total maximum bit rate | |--------------------------------|-----------------|-----------------------| | 2 and below | 5 Mbps | 10 Mbps | |--------------------------------|-----------------|-----------------------| | 3 to 4 | 2.5 Mbps | 10 Mbps | |--------------------------------|-----------------|-----------------------| | 5 to 20 | 0.5 Mbps | 10 Mbps | |--------------------------------|-----------------|-----------------------| * When only MPEG-4 images are distributed When only MPEG-4 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. Maximum number is the same as a frame rate priority mode. Please refer to the table mentioned above.(When distributing only MPEG-4 data) (3) Built-in viewer can display target color of intelligent tracking. (4) Search function is added to intelligent tracking status. When Intelligent tracking misses target color, search function works to get target color again. During the search, Built-in viewer can display the search status. (5) Default settings below are changed. Changed the initial value of AGC to super. Changed the initial value of DHCP to OFF. (6) To make use of the built-in MPEG-4 Viewer of the camera, you will need to install the ffdshow open source codec. Built-in viewer can work with revisions below. 1324 (ffdshow beta3 rev.1324 (20070701)) 1723 (ffdshow beta4a rev.1723 (20071224)) 1920 (ffdshow rev.1920 (20080328)) 2033 (ffdshow beta5 rev.2033 (20080705)) (7) Attached Image of Alarm Mail When alarm trigger is "Color->BlackWhite" or "BlackWhite->Color" and alarm action is "Mail", attached image of alarm mail can be "Black and White" or "Color". 3. New Functionality [3D Noise Reduction] - 3D Noise Reduction, three dimensional digital noise reduction, is implemented instead of previous Noise Reduction. 3D Noise Reduction is powerful noise reduction that improves view in darkness. Options of Noise Reduction in Camera page are changed from Off/On to Off/Low/Mid/High for 3D Noise Reduction. - Note of 3D Noise Reduction The strength of noise reduction is adjusted automatically according to the brightness of view. When "High" is set, the strength of noise reduction is maximum though afterimage of moving object can be noticeable. When "Mid" or "High" is set, the resolution can decrease in dark view. When Sense Up is working, the effect of noise reduction is decreased, and the image of moving object can be unnatural by slow shutter and decreased resolution.
