IV
If your system is set up for multiple users, ensure that each user only has rights to features and
functions they need to use to perform their job.
10. UPnP:
● UPnP will automatically try to forward ports in your router or modem. Normally this would be a
good thing. However, if your system automatically forwards the ports and you leave the
credentials defaulted, you may end up with unwanted visitors.
● If you manually forwarded the HTTP and TCP ports in your router/modem, this feature should
be turned off regardless. Disabling UPnP is recommended when the function is not used in real
applications.
11. SNMP:
Disable SNMP if you are not using it. If you are using SNMP, you should do so only temporarily,
for tracing and testing purposes only.
12. Multicast:
Multicast is used to share video streams between two recorders. Currently there are no known
issues involving Multicast, but if you are not using this feature, deactivation can enhance your
network security.
13. Check the Log:
If you suspect that someone has gained unauthorized access to your system, you can check
the system log. The system log will show you which IP addresses were used to login to your
system and what was accessed.
14. Physically Lock Down the Device:
Ideally, you want to prevent any unauthorized physical access to your system. The best way to
achieve this is to install the recorder in a lockbox, locking server rack, or in a room that is
behind a lock and key.
15. Connect IP Cameras to the PoE Ports on the Back of an NVR:
Cameras connected to the PoE ports on the back of an NVR are isolated from the outside world
and cannot be accessed directly.
16. Isolate NVR and IP Camera Network
The network your NVR and IP camera resides on should not be the same network as your
public computer network. This will prevent any visitors or unwanted guests from getting access
to the same network the security system needs in order to function properly.
