BOLT4 – 4-port HDMI Capture via Thunderbolt


Connect 4 HD cameras to your Thunderbolt 3/4 enabled laptop using the BOLT4 from Tom Sinclair and ESB.

Perfect for portable streaming setups, the BOLT4 fits easily into a backpack with your laptop and cameras. Then back in the studio, it plugs right into your Thunderbolt 3/4 enabled PC. The best of both worlds.

Small enough to fit into a backpack or carry-on bag.


Your live video production software like vMix will recognize the BOLT4 as four separate cameras.
