1. After resetting the system to default settings, the system IP address is still
undetectable or an invalid value
 If the IP/Subnet Mask/Default Gateway shows an incorrect value, you can modify the
value in “Static IP” Mode.
 The default Obtain IP address selection in AVer HVC is in “Static IP”. Please change the
selection to DHCP under LAN Configuration. The system will automatically obtain the IP
address from the DHCP server.

 Check if you have entered the correct system IP address and AVer HVC is on.
 Ensure HTTP Port 80 is opened in your firewall settings.
 Check administrator setting on AVer HVC to confirm Webtool is enabled.

address as DHCP.
