Skype for Business Far End Camera Control Software

Hello USB Pros!

So everyone knows about the new Logitech cc3000e by now right? This has been a great easy to use USB 2.0 video conferencing camera (beside the sub-par speakerphone) for under $1,000! So one thing a lot of people don't know is that the Logitech CC3000e also comes with a free Skype for Business / Microsoft Lync video conferencing plugin that provides the far end with video camera pan tilt zoom controls. Logitech has stated that that both ends do require a "conference cam" meaning either a cc3000e or a bcc950 ptz camera at both ends. Therefore not too many people have actually had a chance to try out this free video conferencing plug-in for skype for business that logitech has made. 

In the video below, Paul Richards, from Conference Room Systems show us the Logitech cc3000e Skype for Business plugin in action using two computers to show remote control over (Microsoft Lync when the video was recorded and posted to YouTube) now Skype for Business. So without further explanation check out this great video of the Logitech cc3000e plug-in in action online using a Windows computer connected to a gigabit network with a 50M up/down network. 

If you have used the logitech cc3000e remote pan tilt zoom plug-in for Skype for Business or Microsoft Lync let us know what you thought! This is a great example of UVC camera control. See our UVC camera control article here: UVC Camera Control and why it is the future? The Logitech cc3000e uses only 1 USB 2.0 cable that comes out of a proprietary USB hub. The webcam and speakerphone include 16' proprietary cables that connect to this USB hub which provides both the camera and speakerphone power. From here the USB hubs can pass UVC control for the camera's Pan Tilt & Zoom operations. No the 16' cables cannot be extended at this time but you can extend the USB 2.0 with a USB 2.0 extension. For more about USB extensions see here: Part 2 - Why USB 3.0 for AV & USB cabling limitations/extensions

Kudos, to Logitech for creating a dynamic plugin for Skype for Business and thanks for reading another post by the USB Pros!

UVC Camera Control and why it is the future?

UVC Camera Control and why it is the future?


Over the years, most conference cameras utilized SDI ports to connect to a receiver and output video. There have been numerous communication ports embedded into devices such as RS-232 and RS-485 serial ports but the most popular has been RJ-45 Ethernet port which is used for IP Streaming. Latest cameras feature Ethernet, SDI, HDMI and Serial ports (RS-232 & RS-485).

Similar to all the innovations, they become obsolete after a certain period of time. We saw SDI taken over by HDMI ports but only RJ-45 is irreplaceable because it has a lot of other purposes. The world is moving towards wireless technology so it won’t be long before RJ-45 is also replaced by Gigabit level wireless technology such as wireless AC 5 GHz network.

Some conference cameras also come with USB 2.0 port but it was unable to transmit video due to low transfer speeds thus manufacturers only used it to update firmwares. Now with USB 3.0 everything has changed and conference cameras can now output Full HD video with the help of 20 times more transfer speed than USB 2.0.

In order to control several features of the camera such as pan, tilt, zoom and rotate; users used RS-232 or RS-485 serial ports and connect it with the controller. This configuration resulted in tangling of wires and confusion amongst the operators. Manufacturers made the process easy by including an IR remote control to operate the camera but it wasn’t enough.

Now there are thee video outputs available in a single conference cam – RJ-45 (IP Streaming), HDMI and USB 3.0. RS-232 or RS-485 ports are included for camera control equipment which requires an external device adding to the cost. With USB 3.0, manufacturers are now able to create a UVC device also known as USB Video Class device. A lot of people have used webcams and these were the first UVC devices which were capable of transmitting compressed video streams in MPEG-2 TS, H.264, MPEG-4 SL, SMPTE VC1 and MJPEG formats.

When using HDMI and IP Streaming output modes, users made use of third-party softwares to control camera movements but UVC eliminates this issue. Now with one simple connection, users can stream video as well as control camera movements with ease.

UVC conference cameras are a must for web-based video conferencing especially for organizations. Managers do not possess the technically knowledge to operate extra camera control units and they want a convenient solution. Below is a comparison between USB 3.0 and RS-232/485 specifications:


USB 3.0



Mode of Operation




 Maximum Cable Length

Not Specified

50 feet

4000 feet

Maximum Data Rate

5 Gbit/s

160 Kbits/s

10 Mbit/s

Number of drivers and receivers

1 Driver

Not Specified

1 Driver

1 Receiver

32 Drivers

32 Receivers


As you can see in the table above, USB 3.0 has a lot more speed compared to RS-485 giving it the ability to transmit video. You can also extend the USB 3.0 cable as much as you like and get a custom cable made which can stretch far beyond 50 feet. In terms of maximum receivers, it is not specified either because there are plenty of USB 3.0 hubs available which can allow you to stream video on more than two displays simultaneously.

Below is the list of UVC cameras by some manufacturers:

UVC Conference Cameras

·        PTZOptics 12X-USB

·        PTZOptics 20X

·        HuddleCamHD 20X-G2

·        HuddleCamHD 12X

·        HuddleCamHD 3X Wide-G2

·        HuddleCamHD 3X-G2

·        Logitech ConferenceCam CC3000e


All major manufacturers are now developing UVC cameras for convenient use during conference calls. Organizations are increasing video conference meetings and require the best hardware available today. These UVC devices are future proof and will dictate the future for a long period of time.

Operators can say goodbye to external camera control equipment and welcome the latest USB 3.0 powered conference cameras. Most of the camera models mentioned above come equipped with a remote to control camera movements. This makes it extremely convenient for anyone to operate the camera without any extra knowledge.

UVC devices now enable the optimal experience every video conference call demanded. UVC cameras are plug and play devices so the setup takes less than 10 minutes. All of these devices are certified to use with popular video conferencing tools such as Unified Conferencing Systems, Cisco, Skype for Business, GoToMeeting, Zoom and so on. Users do not have to spend extra time configuring their cameras with each software they use.

We use USB devices more than once every day and they have been part of our tech life for as long as we can remember. USB flash drives replaced CDs and DVDs and now UVC cameras are ready to replace RS-232, RS-485 and IP Streaming cameras. Users still get the option of these communication ports in the latest cameras if they want to enjoy advanced controls of the external camera control device but they are only useful during live broadcasting of large events not conference calls.
