In the event that your social media, bank, email, etc. account is compromised, you would
not want someone collecting those passwords and trying them out on your video
surveillance system. Using a different username and password for your security system
will make it more difficult for someone to guess their way into your system.
9. Limit Features of Guest Accounts:
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
