Thisoption is only applicable to Motion JPEG video streams.Notes: •If the referrals feature is enabled and you wish to also allow normal access to the Live Viewpage, the product's own IP address or host name must be added to the list of allowed refer-rers.•Restricting referrers has no effect on an MPEG-4 video stream. To restrict an MPEG-4stream, IP address filtering must be enabled.•Restricting referrers is of greatest value when not using IP address filtering. If IP address fil-tering is used, then the allowed referrers are automatically restricted to those allowed IPaddresses.HTTPSThe AXIS 223M supports encrypted browsing using HTTPS.A self-signed certificate can be used until a Certificate Authority-issued certificate hasbeen obtained.
