Hardware recommendations

This page is updated to the 1.4.0 release

Base unit

Galicaster units are assembled with standard computer components and compatible capture devices and cards. For a good experience with Galicaster, we recommend a series of reference units, all of them sharing the common components indicated in this base unit.

Three different references are proposed: an entry level unit (using a HD webcam), a SD based unit and a HD based unit. Other combinations are possible that may fit your needs better. For instructions on how to assemble or purchase a unit, contact us through our multiple communication channels

CPU and RAM requirements

The capture devices used with Galicaster demand a high bandwith capacity and disk writing rate, so a powerful CPU is needed. Depending on the chosen hardware, the following statements will suffice:

  • An Intel i3 cpu, minimum.
  • 64 bits architecture.
  • 4 GB of RAM memory.
The selected hardware must be compatible with your Linux distribution of choice. Our recommendation is using Ubuntu 12.04, since Galicaster is developed and extensively tested in this distribution. Nonetheless, other distributions may work with Galicaster, however some additional testing is advisable.

Touchscreen

Galicaster's Graphical Interface is designed in an user-friendly, easy-to-use, big-sized style, making it suitable for tactile devices, specially high resolution touchscreens. However, there is nothing against using it with a classic mouse and keyboard interface.

Reference units

This section provides some examples of reference units, so that the interested readers can have a reference to begin with. Several combinations can be implemented, even multiple ones on the same unit. Some parameters should be taken into account when making the decission, such as:

  • Pre-existing equipment: cameras, microphones, computers.
  • Recording scenario: lectures, conferences, studio, video-conference.
  • Complementary Hardware: scalers, splitters, audio mixers ...
  • Cost.
  • Publication channels.
