Watch on YouTube Wireless RS-232 & Video for PTZ Cameras

By request, we have demonstrated how you can use the USB2Air to create a wireless RS-232 connection to various devices. For this video it just made sense to show wireless USB video from a PTZ webcam and camera control over RS-232 / DB9 as well. These two products together will provide a camera with wireless video that you can use the SONY VISCA camera controls or other RS-232 methods! So many products support RS-232 and low latency control is important. The USB2Air can be used to create a wireless connection between the wireless transceivers up to 25′.

This opens up a whole new world of wireless camera control options which we are just starting to dig into. For example, if you have a studio full of camera you want to control but would like to do so wirelessly you can now connect them all via daisy-chain to the USB2Air.

The USB 2.0 video is compressed via h.264 and allows us to send video below our bandwidth limitations of the USB2Air. We can also easily send RS-232 commands wirelessly and provide a complete video and camera control solution wirelessly from our computer.

Finally I will mention that we are using the free Rocosoft testing tool for this demonstration. We plan to do more testing with advanced RS-232 control software to confirm compatibility. There are many cameras that can use this wireless RS-232 solution including: SONY, Panasonic, Vaddio and more so we are keen to learn more…
