The DigitalSENTRY client computer connected to the corporate network can access the DS NVR
system and IP cameras when the router is configured to allow the data to pass to the DigitalSENTRY
client. This configuration has the advantage of allowing anyone on the corporate network to look at
live and recorded video while protecting the corporate network from the heavy traffic generated by
the IP cameras and IP servers. The router would also protect the corporate network by restricting the
amount and type of data that would be passed into the corporate network. In both cases, the DSAdmin
software can run on either computer.
6.1 Advantages
6.1.1 Flexibility
While the system is up and running, it is possible to run the DigitalSENTRY client software from just
about anywhere. The router configuration can be modified as requirements change and evolve. The
router can be a single point of upgrade to provide even more flexibility and increase bandwidth.
6.1.2 Security
The router can be used to enhance the overall security. Network access can be managed at the router,
restricting access to the IP camera network. For example, someone with a laptop and DigitalSENTRY
client software can be restricted from connecting and accessing the DS NVR system through the
router itself.
6.2 Disadvantages
6.2.1 Network Administration
Unlike the separate physical network configuration, a router requires the support of a IT group. Using
a router requires a strong networking skill set. The network administrator responsible for maintaining
the corporate network must be involved in installation and configuration, and it will require a large
amount of time to determine the optimal router configuration.
7. DigitalSENTRY 4.0.1
The behavior of the DS Videoerver Service has been change in DigitalSENTRY 4.0.1 to better handle
multiple network ports on a VAU or DS XPress system.
When the service starts, it queries the DigitalSENTRY database for its assigned TCP/IP address. If
the returned TCP/IP address is assigned to one of the network cards, it continues starting up normally.
If the returned TCP/IP address is not assigned to either NIC, the service updates the database with the
TCP/IP address from the first NIC port.
If the TCP/IP address chosen by the service is not the desired address—perhaps it’s a TCP/IP address
valid in the IP camera network but not the corporate network—DSAdmin must be used to update the
TCP/IP address for the VAU.
