2.4 GHz vs Bluetooth
Hello HuddleCam Followers!
Today we wanted to talk about wireless audio conferencing and the leading technologies behind wireless speakerphones. Most of us have used some type of Bluetooth device to wirelessly stream music or even set up a audio conference call. Bluetooth has been the standard for streaming audio and even two audio conference calls. But just like any technology Bluetooth is now becoming out of date as 2.4 GHz provides 100 times the bandwidth with increased reliability. With such a increase in technical specifications and horse power you would think this technology would be expensive right? Well the new HuddlePod Air starts at only $299 which is about $100-200 more than a traditional Bluetooth speakerphone. What is the difference? Let’s review some of the additional features you will receive with 2.4 GHz wireless receiver compared to a Bluetooth connection.
- Ease of Use: No need to pair a bluetooth device
- With a wireless USB 2.0 receiver your computer will automatically load the drivers just like a regular USB 2.0 webcam. Your favorite web conferencing software like GoToMeeting, WebEX or Zoom.US will automatically be selected as your audio device.
- Higher Quality Audio Quality
- With 100 times the bandwidth of Bluetooth the HuddlePod air is able to provide more reliable and rich connection for audio conferencing. Bluetooth is notorious for cutting in and out while losing quality due to the lack of bandwidth available
- Less interference
- Bluetooth is susceptible to interference from Microwaves up to 30′ away. With the 2.4 GHz spectrum the FCC requires the acceptance of interference. Therefore the HuddlePod Air can intelligently “hop” between the available wireless spectrum to lock into the highest quality signal connection.
2.4 GHz wireless spectrum has 100MHz bandwidth pipeline. Bluetooth only has a 1MHz bandwidth pipeline.
Example 1: Hardwired USB 2.0 Speakerphone
Always the best quality, a hard wired USB 2.0 connection is ideal for the highest quality experience. Knowing this is not always possible or required we will dig into wireless technologies for audio conferencing below.
Example 2: Bluetooth Speakerphone
Bluetooth is by far the most popular wireless speakerphone technology because of cost. The quality if fair but as you will see here it is pale in comparison to a hardwired USB connection. Later we will take a look at this same microphone hard wired vs bluetooth.
Example 3: 2.4GHz wireless speakerphone
Now try listening the HuddlePod Air which uses a technology we consider superior to Bluetooth (2.4 GHz). This microphone is recorded “wirelessly” but it still maintains a high quality audio recording.

Today we wanted to review a few ways you can use your HuddleCamHD Cameras to produce live streams. Since every HuddleCamHD camera has USB, the first thing your going to want to do is plug in your HuddleCamHD to a computer with internet. From here we can user a host of online solutions to set up live streams to literally hundreds of thousands of viewers. In fact, video is probably going to much easier than audio (which we may cover in a separate blog post).
Here are just a few services you can use with HuddleCamHD cameras to live stream your audio and video to a online audience:
- YouTube Live – One of the most popular free live streaming services
- Google Hangouts on Air – This is perhaps the easiest way to set up a live stream. You can screen share, invite participants and promote your event all with Googles free tools
- Flash Media Live Encoder – This is a great option to send a RTMP video feed directly to YouTube Live
- Wirecast – Wirecast provides a free encoding service to send video directly to YouTube Live
- VLC – You can open up your webcam in VLC and actually send out a RTMP video feed (but this option does not handle audio well, it’s better suited for internal streaming)
- VMix – This is a great video mixing software that allows you to stream to almost any online CDN from YouTube Live to Wowza
- Check out the video below to see just how easy it is to set up multiple USB cameras for a live production
- You can also turn your entire production into a “Virtual Webcam” and use it with video conferencing software like Skype for Business and GoToMeeting
- This is a great way to use multiple webcams with a software that only accepts one at a time
- Wirecast – This is a professional solution with tons of features
There are many more services but we wanted to state a few just to get the blog post published and ready for conversation. If you have questions or comments please let us know.
Hello HuddleCamHD Followers!
In this post we wanted to review a few ways you can gain camera control for a far end user. During a video conference call with a HuddleCamHD you can use both USB and RS-232 connections simultaneously for video and camera control. USB 2.0 or USB 3.0 will provide the video connection to your web video conferencing software such as GoToMeeting, WebEX, VSee or Zoom.US. Then you can use the RS-232 connection to provide VISCA commands over a RS-232 to USB 2.0 adapter with our control software. Take a look below at the latest VISCA control software.
Using the software outside your network
So once you have the software installed on a Windows PC connected to your network you can host a control page. You can host a IP Address available in any modern web browser or a IP client you can download and install on another Windows PC. Either way you will have access to the camera PTZ controls over your network. But what about outside your network? Well our software will automatically provide a outside IP Address you can use to connect! But you may need to configure your router and consult your IT team. These are a few of the options you can have to gain IP access to the camera controls remotely.
- VPN
- This is the easiest solution to provide remote access to the IP Address on your network. Remote users can securely login to your network and access the IP Address for remote pan tilt zoom control.
- NAT
- NAT stands for Network Address Translation. You can use NAT with configurations to your router to forward your internal static IP address to the far end.
- Dynamic DNS
- Dynamic DNS stands for a Dynamic “Domain Name System”. This system is ideal if you do not have a static IP address. You can use Dynamic DNS to provide far end camera control to your internal IP address for far end camera control with configurations to your router.
