You do not have to buy any of these units to enjoy Galicaster. You can assemble your own HW, download Galicaster SW and use it for free (for non commercial use).
Why "official" Galicaster units?
You can purchase these "official" Galicaster units if you want a Galicaster-based lecture capture agent designed and assembled by the team developing and supporting Galicaster. At TELTEK we carefully select the best components based on performance and stability to assemble these Galicaster units. Before delivery, we install the Galicaster SW and deeply test the unit to ensure a professional out-of-the-box experience in your lecture capture deployments.
