Network Security Advice
Required measures to ensure basic network security of equipment:
Modify the password regularly and set a strong password.
Devices that do not change the password regularly or use a weak password are the easiest to be
hacked. Users are advised to modify the default password and use strong passwords whenever
possible (minimum of 6 characters, including uppercase, lowercase, number, and symbol).
Update firmware
According to the standard operating specifications of the technology industry, the firmware of
NVR, DVR and IP cameras should be updated to the latest version to ensure the latest features
and security of the device.
The following recommendations can enhance your device's network security:
1. Change your password regularly
Regularly modifying the login credentials ensures that authorized users can log in to the device.
2. Modify the default HTTPand data ports
Modify the device's default HTTP and data ports, which are used for remote communication and
video browsing.
These two ports can be set to any number between 1025 and 65535. Changing the default port
reduces the risk of the intruder guessing which port you are using.
3. Use HTTPS/SSL encryption
Set up an SSLcertificate to enable HTTPS encrypted transmission. The information transmission
between the front-end device and the recording device is fully encrypted.
4. Enable IP filtering
After IP filtering is enabled, only devices with the specified IP address can access the system.
5. Change the ONVIF password
For some old versions of the IP camera firmware, after the system's master password is changed,
the ONVIF password will not be automatically changed. You must update the camera's firmware
or manually update the ONIVF password.

Issue: V4.6.X(2022-04-24) v
6. Only forward the ports that must be used
Only forward the network ports that must be used. Avoid forwarding a long port area. Do not set
the device's IP to DMZ.
If the camera is connected locally to the NVR, you do not need to forward the port for each
camera. Only the ports of the NVR need to be forwarded.
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
its permissions.
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.
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.
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.
Physically protect your device
For the safety of your device, we strongly recommend that you physically protect your device
from unauthorized boring operations. We recommend that you place the device in a locked room
and place it in a locked cabinet with a locked box.
It is highly recommended that you use PoE to connect IP cameras to NVR.
IP cameras connected to the NVR using PoE will be isolated from other networks so that they
cannot be accessed directly.
Network isolation between NVR and IP cameras
We recommend isolating your NVR and IP cameras from your computer network. This will
protect unauthorized users on your computer network from having access to these devices.
