Multicast; Image Posting - Sony SNC-HMX70 User Manual

Note
To use the UPnP function on a Windows computer, both
the Universal Plug-and-Play Device Host and the SSDP
Discovery Service must be activated.
Quality of Service
The priority of the different data channels can be set by
defining the DiffServ Code Point (DSCP). Enter a
number between 0 and 252 as a multiple of four. For
alarm video you can set a higher priority than for regular
video and you can define a Post Alarm Time over which
this priority is maintained.

Multicast

The camera can enable multiple receivers to receive the
video signal simultaneously. The stream is either
duplicated and then distributed to multiple receivers
(Multi-unicast), or it is sent as a single stream to the
network, where it is simultaneously distributed to
multiple receivers in a defined group (Multicast).
Multicast operation requires a multicast-enabled
network that uses UDP and the Internet Group
Management protocol (IGMP V2). The network must
support group IP addresses.
Other group management protocols are not supported.
The TCP protocol does not support multicast
connections.
A special IP address from 225.0.0.0 to 239.255.255.255
(class D address) must be configured for multicast
operation in a multicast-enabled network. The multicast
address can be the same for multiple streams, however,
it is necessary to use a different port in each case.
The settings must be made individually for each stream.
Enter a dedicated multicast address and port for each
stream. Switch between the streams by clicking the
appropriate tabs.
The video channels can be individually selected for each
stream.
Enable
Enable simultaneous data reception on receivers that
need to activate the multicast function. To do this, check
the box and enter the multicast address.
Multicast Address
Enter a valid multicast address to be operated in
multicast mode (duplication of the data stream in the
network).
With a 0.0.0.0 setting, the encoder for the stream
operates in multi-unicast mode (copying of data stream
in device). The camera supports multi-unicast
connections for up to five simultaneously connected
receivers.
Duplication of data places a heavy demand on the CPU
and can lead to impairment of the image quality under
certain circumstances.
Port
Enter the port address for the stream here.
Streaming
Click the checkbox to activate multicast streaming
mode. An activated stream is marked with a check.
(Streaming is typically not required for standard
multicast operation.)
Multicast packet TTL
A value can be entered to specify how long the multicast
data packets are active on the network. If multicast is to
be run via a router, the value must be greater than 1.

Image Posting

A target account must first be defined to use JPEG
posting and for the export of recordings.
JPEG posting
Save individual JPEG images on an FTP server at
specific intervals.
Image size
Select the size of the JPEG images that are to be sent
from the camera. JPEG resolution corresponds to the
highest setting from the two data streams.
File name
Select how file names are created for the individual
images that are transmitted.
– Overwrite: The same file name is always used and
any existing file will be overwritten by the current file.
– Increment: A number from 000 to 255 is added to the
file name and automatically incremented by 1. When
it reaches 255, it starts again from 000.
– Date/time suffix: The date and time are automatically
added to the file name. When setting this parameter,
ensure that the date and time of the device are always
set correctly. For eample, the file
snap011005_114530.jpg was stored on October 1,
2005 at 11.45 and 30 seconds.
Posting interval
Enter the interval in seconds at which the images are
sent to an FTP server. Enter zero for no images to be
sent.
