5.5 Changes with FW 5.50.0059
• DHCP is enabled by default with new devices to achieve ONVIF Plug&Play compatibility.
Settings remain untouched during firmware upgrade.
• NTCIP support is now a licensable option for dome cameras.
• Class D IP addresses are denied for standard address fields in Web browser.
• Unused pre-alarm buffer is released when changing the recording block.
• RTSP multicast connections need a retrigger to keep alive, initiated by the CGI parameter
"mcRetrigger", which is set by default.
It can be disabled by setting mcRetrigger=0 in the RTSP URL for environments where no
keep-alive messages are sent. Otherwise the connection will time out after 1 minute.
5.6 New Features with FW 5.50.0059
Encoder
• Predictable rate control for long term recording ensures that maximum bit rate is not exceeded
by peaks due to high motion. This makes storage calculation more reliable.
• Downscaled images from HD cameras can use resolutions with undistorted 16:9 aspect ratio.
• JPEGs are also possible with downscaled resolutions.
• Adaptive Bit Rate encoding is available in TCP mode for replay and live. This is activated as
long as there is only a single client connected to the stream. With the second connection, the
profile settings become active.
• Quality settings (QP settings) are harmonized over all products.
Network
• IPv6 support for Web browser access to product pages, including live view, control and replay,
has been introduced.
• Quality of Service (QoS) allows setting different priorities for video, audio and control
connections.
• IP Filtering allows defining two IP address ranges allowed to communicate with a device.
• Flexible path for FTP can be defined, using a built-in FTP explorer.
• HTTPS encryption using AES and 3DES ensures compatibility with latest Web browser
generations like IE9.
• SNMP community names can be defined.
• HTTP streaming (server push) allows mobile clients to access video.
• MTU can be configured to adapt to network conditions.
