HELO Plus H.264 Streaming and Recording Encoder v1.0 34 www.aja.com
NOTE: When using NFS Network Share, make sure that you take into account any file
size limits on your file system. Configure your HELO Plus so that it doesn't make
file sizes that your storage system cannot handle. For example, you can restrict
the maximum file size by adjusting the bit rate, frame rate, and setting limits of
duration so that clips will not be bigger than 4GB or 2GB. Be sure to set the buffer
size on your NFS server to its maximum to avoid performance issues.
SMB and Record Path
In all cases (SD/USB/SMB/NFS), if the recording directory is not present, HELO Plus
will create one. For SMB, this means HELO Plus must have write permission at the
"bottom" of the SMB Server Address. If the top-level share is Read-Only and the
desired subdirectory is Read/Write, and if the subdirectory is entered as the SMB
Network Record Path instead of as part of the SMB Server Address, recording will
fail.
For example, in a scenario in which there is a top-level READ-ONLY SMB Share on
the network of //ServerName/AVDepartment, and it contains a Read/Write folder
called "MyProject" where clips are to go, the following will work successfully:
SMB Server Address: //ServerName/AVDepartment/MyProject
SMB Network Record Path: - Empty -
In contrast, the following will not work because the SMB server address is read-
only:
SMB Server Address: //ServerName/AVDepartment
SMB Network Record Path: MyProject
HELO Plus needs the SMB share mount point to be Read/Write so that it can
create record paths if they do not exist already, since the user can change this
parameter at any time.
Identical SMB or NFS Directory Used by Multiple HELO Pluses
If multiple HELO Plus devices are configured to record to the same directory on
the same SMB/NFS network storage device, and the HELO Pluses have identical
non-default Filename Prefix settings, it is possible (but unlikely) for more than
one HELO Plus to simultaneously attempt to write to the same file on that SMB/
NFS directory. This can result in failed recordings without warning, because the
fault is not reported until the recording stops or a segment limit is reached.
This problem cannot occur if all the HELO Pluses have their Filename Prefix
settings set to factory default (right click on Filename Prefix and select Reset to
Factory). When set to default, HELO Plus automatically adds a unique device serial
number to all clip filenames, to help ensure all clip filenames are unique.
This problem can also be prevented by making sure each HELO Plus is configured
to write to different SMB/NSF directories, or by having each HELO Plus use
different non-default Filename Prefix settings.
SMB Dialect
Use the SMB Dialect control to select a specific version of the Server Message
Block (SMB) protocol to use with a remote SMB share. Start with Auto unless you
experience long connection delays (two minutes or more), or if you must connect
to a server that only supports SMB1 (also called CIFS or SMB with no version
number), such as macOS X 10.8 Mountain Lion or earlier.
Auto (default) is recommended for most applications. When Auto is selected,
HELO Plus will start with the most secure setting (SMB 3.0), and work its way
sequentially through the list until a compatible setting is found. Generally, the
higher the number, the higher the security.
