5. Number P Frames after I Frame: The more the number of P frames after
each I frame, the more space will be saved on the hard disk, but the more
computation will be needed to uncompress the video for playback. Click
"Apply" and "OK" to activate the configuration.
Note: An I frame is the initial full frame of video information for any given scene, while a P
frame consists only of the incremental changed necessary to form the next frame, rather
than an entire new frame. When the P frame function is set to value higher than the
default setting, for every clip of video, less I frame are sent, so the quality of the image
will be normal, but transmission occurs more quickly and disk space is saved. Users
should set this function according to their specific requirements.
6. Enable Telnetd: To start or stop the telnetd daemon. The default setting
allow user to login DVR system form remote site using telnet utility (for
maintenance). For security consideration, user can disable this function.
Click "Apply" and "OK" to activate the configuration.
7. Limit Out Bandwidth: Users can restrict the total network outbound bandwidth

8. New HD Format: Select the suitable file system file system for your new HD.
Click "Apply" and "OK" to activate the configuration.
Note: ext3 is more stable; vfat can let HD be mounted to Windows system for playback.
9. Virtual Server Setting: If the DVR is only provided with one legal IP, and
besides the DVR host, there are also some other applications (such as
interior on-line computers of a company, the network server, the ftp server,
the email server, etc.) that should be used through Internet connections,
or there are several DVR hosts providing service outwards, then Virtual
Server should be an ideal solution. Virtual Server allows multiple applications
to share one legal IP, by assigning various application requirements
respectively to the interior virtual IP of the company. Basically, functions and
setups of Virtual Server are different depending on the machines' types. So,
please refer to the User's Guide for the Virtual Server you purchased. DVR
should use three TCP ports of 80, 9090 and 992, you will need to open
these three TCP ports on Virtual Server,, or you must fill in the three TCP
ports in this item that corresponding to the three ports assigned by Virtual
Server.
Example:
a. Network Environment (please consult the Net-Supervisor of your
company):
Exterior legal IP: 2.23.4.2
Interior Network of the company: 192.168.1.xx
Interior Netmask of the company: 255.255.255.0
