Breaking the Chain – Going “Wireless” with USB 3.0 Cameras

There is now another means with which to extend USB 3.0 which does not require custom cabling, an additional AC outlet at the device or even the labor required for installation.  Wireless transport for USB 3.0 cameras is now available in the HuddleCam Air 12x and HuddleCam Air 20x camera models, available from HuddleCamHD.  The 12x unit is perfect for the small, medium or large conference room.  The 20x unit is perfect for longer shots in the largest conference rooms, auditoriums and other large spaces.  These cameras provide best in class performance among USB 3.0 cameras as well as the benefits of wireless with near-zero latency for crisp, clear HD conferencing up to 1080p-30.

The cost effectiveness, convenience and user friendliness of soft codec and web based video conferencing is now available in practically any space you can envision it.  Not only have you cut out the cost and hassle of selecting and installing a wired extension system but your system is also portable and may be relocated by simply unplugging the camera and receiver and moving them to another venue.

Part 3 - USB Troubleshooting & Managing USB Power Settings

 USB 3.0 Troubleshooting Issues:

The high power delivery capabilities of USB 3.0 and the developing energy awareness of technology have led to new power management features in USB 3.0 implementation in modern PC operating systems.  While these are valuable additions, they can in fact interrupt the functionality of USB 3.0 solutions and need to be managed.  Below are the USB 3.0 power setting adjustments recommended for the modern Windows OS when using USB 3.0 devices that require continuous service even when inactive (e.g. Camera and Lync or other conferencing software “Room System”).

Part 2 - Why USB 3.0 for AV & USB cabling limitations/extensions

 Why USB 3.0 for AV?

Why use USB 3.0 for AV?  The 5Gbps data rate available with USB 3.0 allows us to send up to 1080p-30 uncompressed video directly to a PC.  This is especially useful for soft codec and web based video conferencing solutions like Lync, Skype, Hangouts, WebEx, GoToMeeting, Jabber, etc...  USB 2.0 is also capable of carrying 1080p-30 resolution but it must first be pre-compressed by the camera (e.g. via H.264 compression) in order to squeeze into the 480Mbps limitations of USB 2.0.  Most cameras do not have this compression built-in but more importantly many applications perform better if the conferencing, streaming or recording software is the only step in the signal chain providing compression to the video stream.

USB 3.0 Cabling Length Limitations and Extensions

USB 2.0 cable lengths were limited by specification to about 5m or 16.5’.  While USB 3.0 cable length is not specifically limited by the specification, the effective max cable length is even shorter at about 3m or 10’.  This is fine for connecting appliances to a PC at your desk but will not suffice for installations in larger spaces (e.g. control rooms, conference rooms, auditoriums, etc...).

Applications for HD Video

What is USB 3.0

USB 3.0 (aka SuperSpeed or SS) is the successor to USB 2.0 and increases the data rate more than 10 fold, from 480 Mbps (USB 2.0) up to 5 Gbps (USB 3.0).  USB 3.0 is often designated by color coding the connector inserts blue, rather than the common black and white connector inserts and by the addition of the “SS” added to the normal USB icon.

USB 3.0 brings a number of improvements over USB 2.0 including: 5Gbps transfer speeds, Full Duplex (i.e. simultaneous send and receive), Sync-N-Go technology that minimizes user wait-time and power delivery up to 900mA (900 mA on PC ports only. USB charging-only adapters can exceed this and deliver higher charging currents of 1A, 1.5A, 2A 3A, etc…).  This upgrade from 500mA to 900mA explains why your smartphone never seems to charge when plugged into your PC’s old USB 2.0 ports but charges steadily albeit slowly when plugged into your PC’s 3.0 port.  Your smartphones original charging adapter may provide between 1A and 2A or on some even 3A.
