Record Diskspace Usage Settings:
Cycle Recording －
When this setting is turned on, the video database system will overwrite the
oldest data if the usage of the current database has reached its storage limitation.
In other words, it will record video data circularly. If this setting is not selected,
i.e. unchecked, a warning message will pop up when it is approaching the
limitation. After that, it stops recording when the limitation of the hard disk
usage is reached.
Reserved space －
This indicates the size of the hard disk to be reserved on the recording disk. If the
recording data exceeds this limitation, the new in-coming video data will replace
the oldest data if "Cycle Recording" was selected. Pre-buffer mechanism will
take some space if some channel is already configured but not recording.
Alert Sound:
You can load custom *.wav file for the sound of alert triggering. You can also hear
the sample of the chosen sound file by clicking on the "Play" button (the button with
black right arrow).
Modulation Mode:
You must select the input signal format (NTSC or PAL) to display the original
resolution of video stream from the remote Video Server / Network Camera series
product.
NOTE: You must select the input signal format according to the camera type or CCD
module type that is connected to the remote Video Server / Network Camera series
product. For remote Video Server / Network Camera series product with CMOS
sensor, the input signal format needs to be set as PAL, regardless of the power line
connected is 50 or 60 Hz.
