The administrator will be removed from the queue 60 seconds after their last PTZ control command. 2. Event - The Axis video server can be set up to take control of the queue and move to a specific position for 20 seconds when triggered by an alarm.
Axis video server - System options System options Security User access control is enabled by default, when the administrator sets the root password on first access.
Axis video server - System options Notes: •If the referrals feature is enabled and you wish to also allow normal access to the Live View page, the product's own IP address or host name must be added to the list of allowed referrers. •Restricting referrers has no effect on an MPEG-4 video stream. To restrict an MPEG-4 stream, IP address filtering must be enabled. •Restricting referrers is of greatest value when not using IP address filtering.
Axis video server - System options Clients and servers in an 802.1x network may need to authenticate each other by some means. In the Axis implementation this is done with the help of digital certificates provided by a Certification Authority. These are then validated by a third-party entity, such as a RADIUS server, examples of which are Free Radius and Microsoft Internet Authentication Service. To perform the authentication, the RADIUS server uses various EAP methods/protocols, of which there are many.
Axis video server - System options The authentication process Axis video device 3 Certificate Q: Certificate OK? A: OK 2 Network switch Q: Certificate OK? A: OK 4 RADIUS server 1 Certificate Authority (CA) Certificate Protected network 1. A CA server provides the required signed certificates. 2. The Axis video device requests access to the protected network at the network switch. The switch forwards the video device’s CA certificate to the RADIUS server, which then replies to the switch. 3.

Axis video server - Glossary VPN (Virtual Private Network) - This creates a secure "tunnel" between the points within the VPN. Only devices with the correct "key" will be able to work within the VPN. The VPN network can be within a company LAN (Local Area Network), but different sites can also be connected over the Internet in a secure way. One common use for VPN is for connecting a remote computer to the corporate network, via e.g. a direct phone line or via the Internet.
