3-8-2. Network Ports
When you connect one or more DVRs to a network through an IP sharing device, each device must have a unique TCP
port number for access to each unit from outside the LAN. The IP sharing device must be configured to forward the
assigned port to the specific DVR.
Note: This port number is listed next to the Port menu option in the Network Setup screen. If you plan to access the
DVR units only from within the same LAN, the TCP port does not have to be changed.
3-8-3. Network Stream
User can set the frame rate and the bit rate for a network stream for a specific channel. Total frame rate is CIF
120fps/100fps (NTSC/PAL). The bit rate can be set from 128, 256, 384, 512 and 768.
<Note> The network streaming is possible to set up to the recording frame rate of the channel.

Network Access Beyond a Router
In order to access the DVR remotely beyond a router (firewall), the user must open TCP
port for command level, live channels and storage channels. The user needs to open 3
ports on the router; the DVR port 5445, 5446, and the WEB port 80.
If this port is not opened properly, the user can not access DVR beyond a router.
