Logitech Rally: A New 4K PTZ Webcam

It was almost 5 years ago that I first posed the question, “Where are the USB 3.0 webcams.” They seem to have finally arrived. Logitech’s Brio is now over a year old. Their MeetUp product, not exactly a traditional webcam, is well suited to smaller meeting rooms, aka “huddle rooms.”

Vaddio and PTZ Optics each have several models available, although they remain focused on 1080p models. A USB 3.0 webcam can deliver uncompressed 1080p30 to a host application, which means that the application doesn’t need to specifically configure the camera for MJPEG or H264 modes.

Logitech Rally Camera

Earlier this year, Logitech teased the availability of a new webcam. This new model, known as Rally, rides atop their webcam lineup, a 4K PTZ camera for video conferencing applications.

As to the basics, Rally connects to a host via USB 3. The connection on the camera itself is USB 3 type C, with a 2.2m C-to-A type cable provided. USB is the sole interface, which sets Rally apart from some of its competition, which may also provide SDI or Ethernet interfaces.

The camera supports UVC 1.5, able to deliver uncompressed, MJPEG or H264 encoded streams. It can deliver 1080p, 720p at 30 fps and 60 fps.

A 15x lens with a 90 degree field-of-view fronts a 13 megapixel sensor delivering up to a 4k30 stream.

The PTZ mechanism provided +/- 90 degrees of movement left-right. Tilt range is from +50 to -90 degrees. When turned off the camera swings down to the –90 degree position effectively providing a privacy shutter.

When mounted upside down the camera automatically senses this, inverting the output image. This makes ceiling mounting a especially simple.

Hacking the Logitech C920 & C930e Webcams

Until recently I did not know that this was possible, but people are hacking the venerable Logitech C920 and C930e webcams. The hardware hacks allow them to be used with a diverse range of high-quality, low-cost, CS lenses.

What started as a series of hacks by Saulius Lukse in Vilnius, Lithuania has turned into a small enterprise. At his Kurokesu site he now sells various things related to his adventures in optics. That includes machined metal cases to refit the internals of the C920/C930e. Korukesu C920 webcam kit

Coming Soon: A Pair of New USB 3.0 Webcams

You might recall my ongoing lament about the lack of innovation in what we now laughably call webcams. If not, here’s a brief refresher…the current state of the art in consumer webcams (IMHO, the Logitech C920 & 930e, released in 2012 & 2013 respectively) are getting quite vintage. Where are the newer models that address current technological front lines, like USB 3.0, 4K resolution, VP9, HEVC, etc?

Well, there appears to be some movement in this area. Although, while interesting, it’s probably not what you expect.
