and special characters.

firmware.
The following are recommendations for enhancing network security of your device:
Change password regularly: Change your device password on a regular basis and keep the password safe. Make sure
only the authorized user can log in to the device.
Enable HTTPS/SSL: Use SSL certificate to encrypt HTTP communications and ensure data security.
Enable IP address filtering: Allow access only from the specified IP addresses.
Minimum port mapping: Configure your router or firewall to open a minimum set of ports to the WAN and keep only
the necessary port mappings. Never set the device as the DMZ host or configure a full cone NAT.
Disable the automatic login and save password features: If multiple users have access to your computer, it is
recommended that you disable these features to prevent unauthorized access.
Choose username and password discretely: Avoid using the username and password of your social media, bank, email
account, etc, as the username and password of your device, in case your social media, bank and email account
information is leaked.
Restrict user permissions: If more than one user needs access to your system, make sure each user is granted only the
necessary permissions.

UPnP if HTTP and TCP port mapping have been enabled manually on your router.
SNMP: Disable SNMP if you do not use it. If you do use it, then SNMPv3 is recommended.
Multicast: Multicast is intended to transmit video to multiple devices. If you do not use this function, it is
recommended you disable multicast on your network.
Check logs: Check your device logs regularly to detect unauthorized access or abnormal operations.
Physical protection: Keep the device in a locked room or cabinet to prevent unauthorized physical a ccess.
Isolate video surveillance network: Isolating your video surveillance network with other service networks helps
prevent unauthorized access to devices in your security system from other service networks.
