7. Use a different username and password on the video surveillance system.
In the unlikely event that your social media account, bank, email, etc. account information is
leaked, the person who obtained the account information will not be able to invade your video
surveillance system.
8. Restrict the permissions of the ordinary account
If your system is serving multiple users, make sure that each user has permission to access only
certain features required for the particular users.
9. UPNP
When the UPnP protocol is enabled, the router will automatically map the intranet ports.
Functionally, this is user-friendly, but it causes the system to automatically forward the data of
the corresponding port, causing the data that should be restricted to be stolen by others.
If you have manually opened HTTP and TCP port mappings on your router, we strongly
recommend that you turn this feature off. In actual usage scenarios, we strongly recommend that
you do not turn this feature on.
10. SNMP
If you do not use the SNMP, we strongly recommend that you turn it off. The SNMP function is
limited to temporary use for testing purposes.
11. Multicast
Multicast technology is suitable for the technical means of transmitting video data in multiple
video storage devices. There have been no known vulnerabilities involving multicast technology
so far, but if you are not using this feature, we recommend that you turn off multicast playback
on your network.
12. Check logs
If you want to know if your device is secure, you can check the logs to find some unusual access
operations. The device log will tell you which IP address you have tried to log in or what the user
has done.
13. Physically protect your device
For the safety of your device, we strongly recommend that you physically protect your device
from unauthorized access. We recommend that you place the device in a locked room and place it
in a locked cabinet with a locked box.
