[. . . ] ·Restricting referrers has no effect on an MPEG-4 video stream. ·Restricting referrers is of greatest value when not using IP address filtering. If IP address filtering is used, then the allowed referrers are automatically restricted to those allowed IP addresses. 31 HTTPS The AXIS 221 supports encrypted browsing using HTTPS. A self-signed certificate can be used until a Certificate Authority-issued certificate has been obtained. Click the Create self-signed Certificate button to install a self-signed certificate. Although self-signed certificates are free and offer some protection, true security will only be implemented after the installation of a signed certificate issued by a certificate authority. A signed certificate can be obtained from an issuing Certificate Authority by clicking the Create Certificate Request button. When the signed certificate is returned, click the Install signed certificate button to import the certificate. The properties of any certificate request currently resident in the camera or installed can also be viewed by clicking the Properties. . . The HTTPS Connection Policy must also be set in the drop-down lists to enable HTTPS in the camera. For more information, please refer to the online help. 32 AXIS 221 - System Options Date & Time Current Server Time - displays the current date and time (24h clock). The time can be displayed in 12h clock format in the Overlay Images (see below). If you want the AXIS 221 clock to automatically adjust for daylight savings time, select the Automatically adjust for daylight saving time changes. From the Time Mode section, select the preferred method to use for setting the time: · Synchronize with computer time - sets the time from the clock on your computer. · Synchronize with NTP Server - the camera will obtain the time from an NTP server every 60 minutes. · Set manually - this option allows you to manually set the time and date. Note: If you are using a host name for the NTP server, a DNS server must be configured under TCP/IP settings. See Network > TCP/IP below. Date & Time Format Used in Images - specify the formats for the date and time (12h or 24h) displayed in the Live View video streams. Use the predefined formats or use your own custom date and time formats. See Advanced File Naming & Date/Time Formats in the online help for information on how to create your own file formats. Network - Basic TCP/IP Settings IP Address Configuration The camera's IP address can be set automatically via DHCP, or a fixed IP address can be set manually. A host name can be used and there are options for setting up notification of changes in the IP address. Notes: ·DHCP is a protocol for automatic IP address assignment on a network. IP address assignment via DHCP may lead to the situation where the IP address changes and you thus lose contact with the unit. [. . . ] Multicast - A bandwidth-conserving technology that reduces bandwidth usage by simultaneously delivering a single stream of information to multiple network recipients. NTSC is the standard format used for televisions in most of North and Central America, and Japan. PAL is the standard format used for televisions in most of the world (other than the US, Canada, and Japan). The PEM-format is often used for representing an HTTPS certificate or certificate request.
