Safety Warnings
Network Security
Please take all necessary measures to enhance network security for your
device.
The following are necessary measures for the network security of your device:
⚫ Change default password and set strong password: You are strongly
recommended to change the default password after your first login and set a
strong password of at least nine characters including all three elements: digits,
letters, and special characters.
⚫ Keep firmware up to date: It is recommended that your device is always
upgraded to the latest version for the latest functions and better security. Visit
GeoVision’s official website or contact your local dealer for the latest 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.
⚫ Disable UPnP: When UPnP is enabled, the router will automatically map
internal ports, and the system will automatically forward port data, which results
in the risks of data leakage. Therefore, it is recommended to disable UPnP if
HTTP and TCP port mapping have been enabled manually on your router.
⚫ 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.
