Video data delivery setting
Parameters of a network camera connected to a camera recorder module can be set.
When setting an ONVIF supported network camera for the camera type, the simple setting mode can be used. (Page 237
Simple setting mode)
The parameters can be set in the "Camera Individual Settings" screen in the module extended parameter. (Page 105
Camera individual setting)
Items that can be set are as follows:
Item Description
Resolution Set the resolution of video data.
The higher the resolution, the larger the file size and the shorter the saving period.
Video Frame Rate Set the number of frames of video data delivered from a network camera per second.
The higher the video frame rate, the larger the file size and the shorter the saving period.
Video Codec Set the encoding method for video data.
• Motion JPEG: The video quality does not deteriorate because JPEG still images are played continuously. The bit rate is
• H.264: Only the part of a video changed from the reference frame is sent. The video quality is lower than Motion JPEG, but
Video Rotation Angle Set the video rotation angle of video data.
Video Quality Set the video quality of video data.
The higher the video quality, the larger the file size and the shorter the saving period.
• High: The video quality is high, but the file size is large.
• Middle: The video quality and file size are intermediate values between 'high' and 'low.'
• Low: The video quality is low, but the file size is small.
Maximum Video Bit Rate Set the maximum bit rate of video data delivered from a network camera per second.
By limiting the bit rate of video data, the video quality becomes lower but the effect on other network devices can be reduced.
Even when limiting the maximum video bit rate, a network camera operates to maintain the video quality; therefore, the bit rate
value may exceed a set value depending on the combination of setting values of resolution/frame rate/video codec/video
quality.
When selecting Motion JPEG for the video codec under the required settings, the maximum video bit rate is not applied.
Precautions
• The range that can be set differs for each network camera. For details, refer to the manual for a network camera used or
perform the communication test in the "Communication Test" screen in the module extended parameter to check the range.
(Page 108 Communication test screen)
• If setting a parameter out of the setting range, either of the following errors occurs:
Network camera video setting error (error code: 1D50H, 1D51H, 1D52H)
Network camera video rotation angle unsupported error (error code: 1D80H)
■Simple setting mode
The parameter setting can be configured with the minimum required items for an ONVIF supported network camera
connected to a camera recorder module.
Set whether to enable the simple setting mode in the "Camera Individual Settings" screen in the module extended parameter.
The resolution and video frame rate can be set for a network camera in the simple setting mode, and the video rotation angle,
video quality, and maximum video bit rate are automatically set according to a network camera used.
higher than H.264; therefore, the file size is larger and the saving period is shorter.
the file size can be reduced and the saving period is longer.
