HELO Plus H.264 Streaming and Recording Encoder v1.0 43 www.aja.com
Multiple AJA devices can be used in unison via the Group Control feature. This
feature is only available via the web UI when the devices have IP addresses
configured under a common network and subnet mask and are connected via
their LAN connections to an Ethernet switch or hub to a host computer. AJA
recommends that all same device models in a Group use matching firmware
versions.
At-a-glance you can see the AJA devices that are present on the same local LAN in
the Network drop-down pane on the right side of the web UI screen. Click on the
device's name to switch the browser to that particular AJA device.
The following AJA devices support Group recording:
• HELO Plus
• Ki Pro GO
• Ki Pro Ultra 12G
• Ki Pro Ultra Plus
• Ki Pro Ultra
Group recording, including automatically matched clip names, operates by
having a Leader send up to three items to the Follower(s) within a Group; a record
start command, a record stop command, and also, if the Leader is a Ki Pro, clip
name data. Ki Pro Followers can accept all three commands, permitting automatic
clip name matching. HELO Plus devices, however, do not support clip name data
sharing. If a HELO Plus is a Follower, it only accepts the record start and stop
commands, not the clip name data. If a HELO Plus is the Leader of a Group, it can
only send record start and stop commands to the Follower devices, so in this case
automatic matched clip naming is not possible.
Parameters for each available device will appear in the Group Controls area. These
include:
• System – displays devices that may be added to a Group
• Format – the input video format/frame rate each system is receiving
• Free Storage – at-a-glance view of the available capacity of the media in each
device
• Group – devices can be added or removed from the Group
• Leader – allows the promotion of a device to the controlling role
• Settings – allows for the configuration of clip names on the Leader and
Follower (Ki Pro units only).
To add a device to a Group, simply select the check box for the device in the
Group column. As a shortcut, if all available devices are desired for a Group, select
the All item below Group. If you want to clear devices from a Group, deselect
them or use the Clear option.
Only one Leader can be in a Group; typically, the IP address for the device you are
viewing the web UI on is the one which should be promoted to the controlling
role. If the device with the IP address that is currently being viewed via the web UI
is selected, a red capitalized LEADER text will appear on the web page above the
columns.
NOTE: AJA devices can initiate recordings among units quickly, but not all units will
begin or end recordings precisely at the same time or the same frame.
