Wireless USB Microphones? Bluetooth vs 2.4GHz

Wireless USB Microphones? Bluetooth vs 2.4GHz

 

Let's take a listen to the Jabra Speak 510. We have two recordings for the speakerphone. One if hardwired with USB 2.0 and one is using Bluetooth. Can you tell the difference in Quality?

As you can tell there is  huge difference in quality which is compounded the larger the room and the harder the microphone has to work. Now let's talk about the alternative technology 2.4 GHz. 2.4GHz is the widely used wireless bandwidth used for WiFi and the FCC has certified this band to accept interference meaning you can have donzens of WiFi (2.4GHz) signals in the same relative area with out a problem. The main difference is the fact that no pairing needs to be done. With 2.4GHz speakerphones such as the HuddlePod Air below you only need to plug in a USB 2.0 wireless receiver into the computer you want to use and the speakerphone will automatically be selected in your web conferencing service. Now the immediate downfall here is that you cannot use this technology with a Smart Phone. So therefore you cannot simply connect your smart phone to a 2.4 GHz speakerphone the way you can with a bluetooth speakerphone and simply make a phone call. But the up side is no bluetooth pairing. So if you are setting up a web conferencing room where you want minimal IT support a 2.4 GHz speakerphone should provide higher quality experience with less IT support.

USB Cameras with RS-232 Control

USB Cameras with RS-232 Control

 

We will name off a few USB PTZ cameras that include RS-232/RS-485 control and include them in this article. Breaking through this barrier of USB PTZ Cameras and Serial Control will lead to a higher adoption of web conferencing with traditional audio visual integration companies who rely on control systems to provide full proof "we can do anything" solutions. Large Audio Visual integration firms such as Whitlock, AVI/SPL and Carousel Industries are going to want to keep their highly skilled crestron and AMX programmers designing systems while at the same time remaining relevant in the world of "web video conferencing". To do this they need products that support USB 2.0 or USB 3.0 while at the same time support RS-232/RS-485 serial control they use. 

Here I will list a few USB Pan Tilt Zoom cameras that have both USB and RS-232.

  • HuddleCamHD 3X
  • HuddleCamHD 10X
  • HuddleCamHD 12X
  • HuddleCamHD 20X
  • HuddleCamHD 30X
  • PTZOptics 12X-USB
  • PTZOptics 20X-USB
  • Vaddio RoboShot 12X
  • Vaddio ClearVIEW

Until the HuddleCamHD camera line came out the Vaddio ClearVIEW was one of the only cameras with this capability. That was a tough sell at times especially for smaller applications because the price tag is $4,000! Now we have options from HuddleCamHD and PTZOptics. In Fact, PTZOptics has a nice little comparison between the Vaddio RoboShot and the PTZOptics camera line I will show below.

Serial control can also come in handy for production studios. As live broadcasting and now "Web Casting" become more and more popular the demand for high quality USB pan tilt zoom cameras increase. Many of these production studios are accustom to using PTZ joystick controls that operate with RS-232. So being in the industry I have seen the eyes pop when the customer sees a product with both USB and RS-232 and the combination has been something of a success as of late.
