“Nice to have” recommendations to improve your network security
1. Change Passwords Regularly
Regularly change the credentials to your devices to help ensure that only authorized
users are able to access the system.
2. Change Default HTTP and TCP Ports:
● Change default HTTP and TCP ports for Dahua systems. These are the two ports used
to communicate and to view video feeds remotely.
● These ports can be changed to any set of numbers between 1025-65535. Avoiding the
default ports reduces the risk of outsiders being able to guess which ports you are using.
3. Enable HTTPS/SSL:
Set up an SSL Certificate to enable HTTPS. This will encrypt all communication between
your devices and recorder.
4. Enable IP Filter:
Enabling your IP filter will prevent everyone, except those with specified IP addresses,
from accessing the system.
5. Change ONVIF Password:
On older IP Camera firmware, the ONVIF password does not change when you change
the system’s credentials. You will need to either update the camera’s firmware to the
latest revision or manually change the ONVIF password.
6. Forward Only Ports You Need:
● Only forward the HTTP and TCP ports that you need to use. Do not forward a huge
range of numbers to the device. Do not DMZ the device's IP address.
● You do not need to forward any ports for individual cameras if they are all connected to
a recorder on site; just the NVR is needed.
7. Disable Auto-Login on SmartPSS:
Those using SmartPSS to view their system and on a computer that is used by multiple
people should disable auto-login. This adds a layer of security to prevent users without
the appropriate credentials from accessing the system.
8. Use a Different Username and Password for SmartPSS:
