    2. which
  2. that are
    3. in use

  30. Enable 64-bit modules if more than 25 Tracker objects are to be used on one Server with video resolution higher than 800x600.
  31. Digitization bandwidth depends on the audio card parameters and software limitation from 0 to 48 000 Hz.
    32. Do
  32. To correctly record audio from Axis IP cameras when you use the AAC audio codec, do not set the audio bitrate
    33. value
  33. to 8 or 12
    34. kb/s when
  34. kbps at a sampling frequency
    35. is
  35. of 8 kHz
    36. for correct sound registration from Axis IP-cameras using the AAC codec; it is recommended to use the bitrate value equals to
  36. : the bitrate must be 16, 24, 32, 48, or 64

  41. 711 codec instead.
  42. Different
    43. Servers
  43. servers are not allowed to be connected to one database. Use of a remote database by

    45. to
  45. for the network and
    46. others
  46. other resources and
    47. may
  47. can cause delays when sending events and states between cores that can affect the system.
    48. Axxon PSIM software package of one version is to be installed
  48. You must install the same version of Axxon PSIM, including the build number, on all components of the distributed system.
    49. It is recommended to leave
  49. We recommend leaving the Decompressor field empty on the settings panel of the Camera object or
    50. use
  50. using the Motion Wavelet decompressor when
    51. using
  51. you use WS7 and WS17 video capture cards. Correct operation
    52. of
  52. of Axxon PSIM
    53. software
  53. is not guaranteed if you select other decompressors
    54. are selected
  54. .
  55. Partial decompression is possible when
    56. using
  56. you use MPEG4, MJPEG, MXPEG, Motion Wavelet, and H264svc codecs. Partial decompression for H263,
    57. H264avc and Mpeg2
  57. H264AVC, and MPEG-2 codecs is not supported.
    58. Fps decreasing only is supported by H264svc-t codec
  58. For H264svc-t, only FPS reduction is supported.
  59. If you select the MPEG4 format of recording to archive
    60. is selected
  60. , the loss of a part of the video record
    61. part
  61. is possible (about 0.5 seconds from the video recording beginning).
  62. If the Recording frame rate parameter (the Camera object, the Basic settings tab) is set to non-zero, regardless of its value
    63. of
  63. , recording to the archive is performed only by
    64. anchor
  64. key frames if the H.264 codec is
    65. in use
  65. used. If
    66. the
  66. the Hot record rate parameter for the H.264 codec is also
    67. in use
  67. used, then the recording to the archive
    68. will be
  68. is performed by
    69. anchor
  69. key frames too. If the Recording frame rate parameter is set to 0 or not set, all frames are recorded to the archive.
  70. If 64-bits modules are in use the following items are not supported:
    1. The Scene object (see Configuring object's panoramic view by means of the Scene object).
    2. Some detection tools from DetectorPack (at the moment of writing the documentation − the barcode detection tool only).
    3. Arena module and Auto-Uragan license plate recognition as a part of Auto PSIM.
    4. ACFA PSIM modules.
    71. Grooming on Videogate
  71. Decimation on videogate can be performed using MJPEG, Motion Wavelet, MPEG, H.264, and
    72. MxPeg
  72. MxPEG codecs. If the
    73. grooming
  73. decimation rate is 25
    74. fps
  74. FPS,
    75. then the
  75. then the first minute of video
    76. will be
  76. is displayed at a lower speed (~12
    77. fps
  77. FPS). For the MXPeg codec, the maximum allowed
    78. grooming
  78. decimation rate is 12
    79. fps
  79. FPS.
    80. Web
  80. The web server displays video only in MJPEG format. When transferring video to the
    81. Web
  81. web server, the video stream is recompressed to MJPEG format.
  82. It is required to add
    83. Web
  83. the web server address to the Java exceptions in order for the web server to
    84. Web server
  84. work with JRE 7u51 or later versions.

  91. Use of more than 100 scripts/programs on one computer
    92. may
  92. can cause system instability.
  93. Only files of WAV format can be
    94. in use
  94. used as
    95. the
  95. the Play audio file action parameter of the Audio player object. Otherwise, the Play audio file action is not performed.
  96. The External window object is specialized
    97. on
  97. in working with
    98. onebox applications
  98. single-window apps. If the
    99. application

    102. application
  102. the app is started.
  103. PureVideo/CUDA technology in
    104. the
  104. Axxon PSIM
    105. software
  105. is applied only for video
    106. signals
  106. signal decompression in the H.264 codec. PureVideo/CUDA technology is not used for video signal compression if a resolution more than 1920x1088 is set in the camera.
  107. Recording to the archive is performed only in the color mode
    108. if SC590N4
  108. if the SC590N4 video capture card with
    109. h
  109. the H.264 format of video signal compression is
    110. in use

  113. the server using SC3B0N16 (WS216) and SC390N16 (WS16) cards is performed only with 352x288(PAL)/352x240(NTSC) resolution.
  114. Only key frames are played back when the archive is played back fast in H264 and MPEG4 formats.

  115. Video signals are not transferred to PSIM-based vertical modules using the Videogate module. These modules always receive video

    116. signal

  116. signals directly, like other modules.

  117. There is no sound transmission to the
    118. RMW
  118. remote workstation via the Videogate if different subnets are
    119. in use
  119. used.
  120. When working with Axxon PSIM, do not use power-saving modes, such as sleep mode or
    121. a “Power
  121. a “Power saver” power plan, so that
    122. the CPU clockspeed
  122. the CPU clock speed does not get lower
    123. that
  123. than the base speed.
  124. Axxon PSIM
    125. does not support
  125. supports NVIDIA® Mosaic™ multi-display technology only when used in conjunction with NVIDIA Quadro Sync (see the relevant NVIDIA documentation). Without NVIDIA Quadro Sync, video playback time can vary by ~10-200 ms between monitors.
  126. The following isn't supported:
    1. Some detectors from DetectorPack (at the moment of writing the documentation—the Barcode detector only).
    2. Auto-Uragan license plate recognition as part of Auto PSIM.
