• Auto Traffic Control
Set a limitation on user network resources by designating the maximum bandwidth.
-. Maximum bandwidth - In case of sharing other network programs or equipment, it is
possible to set a limitation on the maximum bandwidth in the unit of Mbit/s or kbit/s.
-. Auto frame rate - Selected if not influenced by a network-related program or
equipment without a limitation on the network bandwidth.
▼ NAT Traversal
A broadband router allows devices on a private network (LAN) to share a single connection
to the Internet. This is done by forwarding network traffic from the private network to the
"outside", that is, the Internet. Security on the private network (LAN) is increased since
most broadband routers are pre-configured to stop attempts to access the private network
(LAN) from the public network/Internet.
Use NAT traversal when your VK2-540VRDs are located on an intranet (LAN) and you
wish to make it available from the other (WAN) side of a NAT router. With NAT traversal
properly configured, all HTTP traffic to an external HTTP port in the NAT router is
forwarded to the network camera.
Notes:
-. For NAT traversal to work, this must be supported by the broadband router.
-. The broadband router has many different names:
"NAT router", "Network router", Internet Gateway", "Broadband sharing device" or
"Home firewall" but the essential purpose of the device is the same.
