Standalone VGA Grid FAQs

Frequently Asked Questions

What are the differences between Standalone and Networked VGA Grid solutions?

Both solutions support  DVI, HDMI™, VGA, component, S-Video or composite cables, however Standalone VGA Grid also supports SDI (3G, HD and SD).

For a Standalone VGA Grid solution the video and audio sources are directly connected using DVI, HDMI, VGA, component, S-Video or composite cables. For a Networked VGA Grid solution the sources are remote and are attached via DVI, HDMI, VGA, component, S-Video or composite cables to HD Encoders.

For the Standalone solution, the VGA Grid captures and encodes data from the sources. It also synchronizes, records and streams the data. In the Networked VGA Grid solution, capture and encoding happens in the HD Encoders and this encoded data is transmitted across an Ethernet/IP network to the VGA Grid Concentrator which performs synchronization, recording and streaming of the received data.

Can Standalone VGA Grid capture IP cameras?

Yes! Standalone VGA Grid can capture from RTSP sources over a network (such as IP cameras). See our online user guide for a list of RTSP cameras we have tested so far.

How much storage does the VGA Grid have for recording?

The Standalone VGA Grid comes with a single 6 TB HDD for recordings.  This can be upgraded to include more storage, to support RAID, or swapped for SSD instead of spinning disks.

How many video sources can VGA Grid include in a multi-source layout?

The VGA Grid has no set limitations on how many video sources can be combined into a single multi-view channel.  Therefore the limit is the maximum number of video sources (12 HD + 6 SD, or 8 HD + 4 SD for the 4-card version) which can be connected.

How many video channels can a VGA Grid system record and stream at the same time?

A Standalone VGA Grid solution can simultaneously capture, record and stream 12 HD video sources, 6 SD video sources, and 7 audio source (8 HD, 4 SD and 4 audio for 4-card solutions). 

What is the difference between a VGA Grid and a VGA Grid Concentrator?

A VGA Grid refers to a Standalone VGA Grid solution which contains internal capture cards for direct connection of video sources.  A VGA Grid Concentrator is a part of a Networked VGA Grid Solution which contains no internal capture cards; instead it receives data from connected VGA Grid HD Encoders.

Can I connect a VGA Grid HD Encoder to a Standalone VGA Grid Solution?

No. VGA Grid HD Encoders are only for connection to a VGA Grid Concentrator (which has no internal capture cards) as part of the Networked VGA Grid solution.

Does the VGA Grid perform playback of recorded files?

Not directly.  Recorded files can be shared to media players using UPnP and SAP or downloaded from the VGA Grid to a computer which can then perform playback.  Alternatively, recorded files may be automatically transferred using FTP, RSYNC or CIFS to centralized network storage to facilitate subsequent access and playback.

How do I know how much storage is required for my application?

The amount of storage required depends on the number of channels, the bitrate of those channels, and the amount of time for which the channels need to be recorded. The bitrate for each channel is configurable. Totaling the bitrates for all channels and then multiplying by the amount of recording time gives a good approximation of the storage required.

How many streaming clients can the VGA Grid support for a single stream?

The Standalone VGA Grid can support many (100+) simultaneous streaming clients using unicast connectivity to each of them. It supports multicast and RTSP/RTMP for connection to video servers (e.g. Wowza) or Content Delivery Networks to support streaming to a very large number clients.
