4.2 Disadvantages

4.2.1 Limited Flexibility

Every user requires a dedicated computer connected to the IP camera network. Computers on the IP

camera network do not have access to the corporate network; another computer would be necessary to

access the corporate network.

4.2.2 Limited Access

The physically separate network limits the IP camera network’s access to any video data. There is no

way for a computer that is connected to the corporate network to access any data from the NVR.

5. Separate Physical Network Using Dual NICs in the NVR

This design is similar to setting up two separate networks; however, it has the advantage of accessing

data from the DS NVR system from a computer connected to the corporate network. The DS NVR

system with two network cards (dual NICs) is able to communicate on the corporate network as well

as the IP camera network. It is important to note there is no direct network connection between these

two networks. See Figure 2.
