Product Listing:

Beelink SEA I 32GB US Model


In this model Beelink used the Realtek RTD 1295DD Quad Core Cortex A53 CPU running up to 1.4GHz. Unlike its Amlogic counterpart, the Realtek 1295DD has support for both Android and OpenWRT. However, the Beelink SEA I only comes with Android OS. Another different feature the Realtek CPU has is PIP recording via HDMI input port. This allows you to use the box as a DVR for recording and storing media from various devices such as, camcorders, DSLR Cameras, Blu-Ray Players for those who like to rip movies, even record video from another TV Box. Now that is going to require massive storage capability. Beelink has taken care of that too.

When it comes to memory and storage, this is where the Beelink SEA I shows off some really cool features. Because this box can be used as DVR you need massive storage and performance capabilities. Because 4K content is really large in size, and the regular internal storage of TV boxes cannot handle that volume of content.

So to solve that issue the Beelink SEA I comes with a 2.5 inches SATA HDD/SDD docking bay, where you can install a removable hard drive or SSD drive for storage in what ever Terra-bites (TB) size of hard drive you want. Also the Beelink SEA I comes with 2GB of DDR4 RAM and 32GB of internal storage. On top of that, you get convertible storage on Android 6.0, so imagine what you can do with all that storage capability.
