• Bitrate Type: Select Variable (default) or Constant. If “Variable” is selected, the
bandwidth can vary depending on video quality and the bandwidth required. If
“Constant” is selected the video streaming is always at the maximum bit rate
selected.
• Video Quality: Select the quality at which to record. If “Constant” is selected as
the bit rate type, this option is unavailable.
If a low video quality is selected, the image quality is poorer and the bandwidth
required is reduced thereby allowing recording over a longer period of time.
• Frame Rate: Select the recording frame rate.
• Max. Bitrate mode: Select the general (Default) or customized option.
• Max. Bitrate (kbps): If the customized maximum bit rate mode was selected,
enter the value here. It must be between 32 and 4096 kbps. It is calculated from
the frame rate and time required. Default is 1792.
• Pre Event: This is the time the camera starts recording before the event. Select
the time in seconds from the list to start pre-recording before the event. Default
is 5 seconds.
The maximum pre-recording times available depend on the constant bit rate.
See “Maximum pre-recording times” in the appendix.
• Post Event: This is the time the camera continues to record after the event.
Select the time in seconds from the list to stop post-recording after the event.
Default is 5 seconds.
• Auto Delete (day): Select the number of days after which recorded video from
the specified camera is permanently deleted from the HDD. A “day” is defined as
the 24-hour period from when the auto delete mode (ADM) was set.
The maximum number of days that can be set is 365. However, the actual
number of days permitted depends on the HDD capacity. If the value is set to ‘0’,
the option is disabled. Default is Disable.
• Record Audio: Enable to record sound with the images. Default is Enable.
