Connecting VISCA Camera

Monoprice camera 39512 with

• VISCA-controlled Pan/Tilt/Zoom
• 1080p
• USB connection to computer
• VISCA serial socket present

Pleasant surprise: the USB3 interface includes a built-in USB->UART chip, so a single USB3 cable can be used for both VISCA control and video streaming.

Installation on Linux

No to braille display:

sudo apt remove brltty

Connect your USB camera - this may result in /dev/ttyUSB* being created! Mine did just that!

Connect USB->serial converter, then check kernel messages for possible errors:

journalctl -b | tail -40

A device should have been created:

ls -la /dev/ttyUSB*

Expose it to all:

sudo chmod a+rw /dev/ttyUSB0
