Zoom Room Update – January 28th, 2022

We met with Zoom today and reviewed some of the options in Zoom Room software and hardware and talked about some new features:

  1. Smart Gallery – Using a digital camera (not PTZ camera), Zoom Room software can take a wide shot of conference table and using AI, break it up so that there are multiple close ups of each individual participant. This helps avoid the “security camera” view of a conference room table.  This is limited to certain Zoom appliances today but will be coming shortly to Mac/Windows Zoom rooms. For more information: https://blog.zoom.us/all-you-need-to-know-about-smart-gallery/
    1. Smart Gallery also supports the simultaneous use of two cameras – For example, simultaneous front and rear facing cameras or instructor camera and document camera.
  2. Focus Mode – Another feature in Zoom Room software allows the instructor to turn off all participants cameras (so they only see participant’s names) and only broadcast their camera. They can still see all the participants cameras to make sure they can keep an eye on things. https://support.zoom.us/hc/en-us/articles/4411732965389-Using-focus-mode-in-a-Zoom-Room
  3. Companion Whiteboard – Although requiring a second license, this allows you to deploy a touch device to an existing zoom room to use it as a dedicated white board: https://support.zoom.us/hc/en-us/articles/360038401111-Setting-up-a-companion-whiteboard-in-a-Zoom-Room

We also briefly discussed hardware options alternatives to Logitech including solutions from Poly (formerly Polycom – merged with Plantronics) and Neat. We’ll be planning a DDMC meeting in the next week or so with Poly to discuss some of their solution. One feature that caught my attention was Poly’s inclusion of a USB-C plug that allows you to connect the system to your computer and use their camera, speaker and microphone on your laptop – if you needed to connect to Skype, Go To Meeting, etc… Poly’s NoiseBlock.ai seems pretty cool as well – especially in our new media lab with the loud air exchanges.


Neat Pad

The good folks over at Neat were nice enough to send us a Neat Pad evaluation unit to test in Duke’s Zoom Room environment. Neat says that their Neat Pad is “a simple and elegant touch screen you can configure as a controller inside your Zoom Room, or use as a scheduling display outside any meeting room,” and it delivers! But, is it for everyone?

First, why would a University want a Neat Pad when options like an iPad or various other 3rd party controllers (Crestron TSW-770 for example) are available as Zoom Room controllers?

An iPad works wonderfully as a Zoom Room controller and is usually updated first when Zoom pushes out an update to the Zoom Room platform. But, at the end of the day, it’s still an iPad with all the little quarks surrounding such a universal device. Specifically, an iPad has a less than ideal charging system for conference rooms. The iPad also requires mounting/security hardware, etc. etc. Finally, if the iPad isn’t using ZDM, the iPad is basically another enterprise computer to manage, both the iPadOS and Zoom Room application need to be maintained. Plus, iPads have a tendency to “grow legs” as they are recognizable mobile devices. Having a wireless option is nice, but not so much when you need to send a technician to a conference room to “plug in the iPad” after a faculty/staff/student has forgotten to reconnect the iPad to a charger (or when the charging cable goes missing).

Many 3rd party controllers have nice features including Power over Ethernet (PoE) to provide clean wired network connectivity and power over a single cable, but they too require a good bit of management, occasionally requiring a specific skillset unique to AV technicians. While these devices usually have the advantage of being used for other applications outside of the Zoom Room environment… updating the firmware (specifically “Firmware Friday“) sometimes isn’t for the faint of heart.

The Neat Pad, in contrast, eliminates many of the challenges mentioned above. Unlike an iPad, the Neat Pad is tethered via a network connection for Internet access and power so while less “mobile” than an iPad, it is less likely to walk away. Also, because it’s not an iPad, people are usually less inclined to attempt to disconnect or “borrow” the device. Setup, unlike an iPad and other 3rd party controllers, takes <3 minutes and can be fully managed from the Zoom environment (aka, once connected, all management of the device is implemented by Zoom’s native web interface – no fumbling around with a hardware manufacturer’s specific software or cryptic embedded web pages for firmware updates. It’s all Zoom). As for price, the Neat Pad has an MSRP of $500. While that’s more expensive vs. an iPad, once you add in the additional hardware to make an iPad function in a conference room, you are quickly approaching that price point (not to mention the time involved with configuring the iPad). The Neat Pad is also less expensive than comparable 3rd party controllers. The only “cons” (and I hate to use that label – perhaps “consideration”) to the device would be that it will only run the Zoom Room environment – either as a controller or room scheduler (both worked wonderfully). It’s never going to run Microsoft Teams, O365 calendaring, Appspace, EMS, Robin, etc. etc. It runs Zoom Rooms and it does that well. One other consideration is that the Neat Pad usually trails a few weeks, perhaps a month, behind the official version of Zoom Rooms in terms of the app update (other 3rd party manufacturers do as well ). Finally, if I had a “Gee, I wish Neat would…” item, it would be that I wish they had a 10″ and 12″ version. The 7″ Neat Pad is great, but there are some locations where having a little more real estate would be ideal.

Level It Out

I was recently contacted by a staffer that had wildly differentiating audio levels for participants in a Zoom recording:

They had tried using “Normalize” but unfortunately the difference between the two was too much for that plug in to handle. This looks like a job for the “Hard Limiter”! Hard Limiter is a standard plug in available in the “Audio Effects” panel of Adobe Premiere. Most NLE’s will have a similar plugin.

If you measure the max level (in db) for your lowest audio, you can set your hard limiter to that level and it won’t allow any of the other audio above that level. This won’t help if one of your audio participants are over modulated or distorted.

In today’s world of remote interviews where we have no control over the participants audio, the hard limiter will be of great value.

Building A Better Border

One of the challenges with Final Cut Pro’s “Simple Border” effect is that it will not work if you crop the image. There are work arounds for this but I found a better solution. BretFX’s Better Border is a free plugin for Final Cut that allows you to crop and put on a border with one tool. I had a pretty complex border project (personal) and wouldn’t have been able to do it without this tool.

Check out the site as there are other reasonably priced plugins such as their Splitz effect that might make compositing multiple speakers much quicker.


Middle Atlantic RLNK-215

Technically, this isn’t an “AV specific” piece of hardware, but the Middle Atlantic RLNK-215 makes its way to AV racks regularly and for good reason. The two-outlet “intelligent power” control device provides basic metal oxide varistor (MOV) surge protection to your AV system, network device, or server. What makes this device unique is that when you connect the RLNK-215 to your network, it offers an easy to use web interface that enables you to independently turn the outlets on and off. While this may not sound like such a modern marvel, consider a scenario where you need to perform a quick hard reboot to your fancy new AV system after a failed firmware update. One quick power cycle should do the trick. Oh, did I forget to mention that the AV system is 100 miles away, on an island, and it’s a Saturday afternoon? Having the ability to remotely hard reboot a system can come in handy in several situations and this device allows you to easily and securely perform that task. The RLNK-215 is also capable of fully integrating into your AV system of choice (Extron, Crestron, etc.) to power devices on or off (amps, lights, fans, etc.).

[Above: Screenshot of the various ways to password protect the Middle Atlantic RLNK-215 for users, admins, and control systems.]

I know what you are thinking, “But didn’t I see something like this for $29.95 online?” Perhaps, but there are reasons you buy such a device. First, it’s not an Internet of Things device, pinging home to a centralized server. This device is fully self-contained and does not require access to the greater Internet. Also, the device is well constructed with a metal outer shell and locking power cable to prevent accidental power disconnects. The device is RoHS and UL listed (60950-1) which is important in many installations. Finally, and perhaps most importantly, the device is backed by a three-year warranty and a group of people that stand behind the device should you experience issues.

Bottom Line: While these devices may sound like a luxury at times, it allows you to more centrally manage AV systems, especially when you have limited staffing resources or a large AV footprint across a sprawling campus.

Webcam/Tripod Review

I recently moved into a new home and my previous method of mounting my webcam wouldn’t work in my new home office. I thought I would try one of the low cost webcams offered on Amazon since it came with a tripod mount and said it featured a wide angle lens. I’m very impressed with the performance for a $30 webcam. The tripod was a perfect fit. Even though I’m not using the included gooseneck, for $18 this seemed like a great deal. Using the tripod set behind the laptop allows me to position my screen at an angle for easier viewing without having the built in camera looking “up my nose”

For those that don’t know me, I’m the guy that looks like he’s sitting in Guitar Center. 🙂

mmhmm, Taking Advanced Online Presentations to the Next Level

As we enter year 700 of COVID-19, some faculty and staff are looking at 2021 wondering how they can spice up their online teaching environment without spending hours or days learning a full-blown video production application. While Zoom offers a wide range of ever-expanding features, there is still plenty of room for growth and mmhmm, a startup from Phil Libin, is capitalizing on that need.

First and foremost, mmhmm acts like PowerPoint steroids. You can supercharge your presentation by your webcam video overlayed on rich media content elements such as slides, images, videos, sounds, etc. Best of all, I was able to pick up the basics of the application in under 20 minutes or so, your mileage may vary. The easy drag and drop configuration nature of the application will have you creating or enhancing your presentation in minutes. Best of all, you can save your layout so that the next time you present, unlike Zoom, you won’t need to reposition your webcam feed, content location, etc.

Where mmhmm really excites us is its ability to feed that content into Zoom and a range of other video applications as a virtual camera or piece of content. While Zoom has enhanced a few features in this area over the past 6 months, mmhmm is considerably further along when it comes to rich presentations. On top of that, mmhmm is capable of capturing your presentation locally in a high-quality .mp4 video file WHILE also sharing that presentation with Zoom. Yes, Zoom can record the session, but sometimes you want a higher quality version, or you would rather not have the participants being a part of your recording. It’s the best of both worlds.

Finally, mmhmm has a copilot capability that will allow a remote participant to manage aspects of the presentation. This would come in handy when you have large productions where people are working together advancing slides. Perhaps not something for everyday use, but for power users… this could be a game changer.


  • It just works!
  • Adds a level of sophistication to presentations, when you have the rich content
  • May allow for a better teaching delivery
  • Simplifies tasks that could take 30-60 seconds in Zoom (30-60 seconds doesn’t sound like long, but when you perform that task 20-30 times during a class, it’s an eternity)
  • The ability to save rich presentations can’t be understated… and is a feature lacking in Zoom. Having to “reset” your video layout can be problematic.


  • The subscription pricing model is… well, expensive ($9.99/mo or $99/yr – no educational pricing to be seen)
  • mmhmm can consume a considerable amount of processing power. The fans on my MacBook Pro were screaming when running Zoom and mmhmm with advanced videos, etc. in the content box. I’m sure the new MacBook Pro with the M1 CPU won’t even blink.
  • You CAN do much of what mmhmm does with free and open source applications if you are willing to invest a good bit of time learning such platforms (which can be buggy at times), but mmhmm packages it up in a more faculty/staff friendly package.

Atlona Professional HDBaseT PTZ Camera

While on a classroom technology Zoom session, a peer institution mentioned that they had installed a few Atlona cameras in a subset of their classrooms. While I was somewhat familiar with Atloma as a complete AV solutions manufacturer, our University has primarily been a Crestron/Extron/Biamp/Vaddio/Sony house, with a wide range of exceptions depending upon the location. One challenge opportunity we’ve faced is the cost of reasonably high-quality cameras in our somewhat smaller classroom and meeting environments. Once two cameras are added to the av design (one facing the students and one facing the faculty member), you can be in the $8,000+ neighborhood without breaking a sweat. That price is before you start the conversation about a projector, mics, DSP, control processors, touch panels, and signal routing. When you start looking at less expensive camera options, you usually see one of three things happen: You lose most (or all) support for the device and the warranty is very limited, the image quality doesn’t meet acceptable baseline standards, or the device lacks professional long-distance connections (power/video/control).

After testing the device, on and off for a few weeks, I was pleasantly surprised to see that the Atlona camera ticks a wide range of boxes. Obviously, the cost of the device is good… but controlling the device is straightforward and the HDBasseT connection was familiar and compatible with a wide range of devices (Atlona or otherwise). Within twenty minutes or so, the device was added to my test environment and I was able to see the camera’s feed and send control commands to the camera. It just worked…


  • Cost… cost… cost. With many professional PTZ cameras topping out in the $4,000+ range, it’s nice to see an option that’s literally <25% of that price point. This is a value-focused device.
  • HDBasseT/Power/Control: With a single connection, you can send power, receive a video signal, and send control commands to the Atlona camera. The HDBasseT seemed solid during my testing and it was nice that it could all be done over a single cable (no need for power near the camera, running a second RS232 cable, etc.). The camera can be placed up to 100m from the receiver, which accommodates many teaching environments.
  • It just works: From the web-based GUI, included remote, and industry-standard HDBasseT output, it just worked.
  • Warranty: I just couldn’t get past the limited product warranty of 10 years for electronic circuit and optics, and 3 years for PTZ motor.
  • Value: I can’t get past the value these devices offer, with support.


  • Build Quality: The camera felt a little… “plastic-ey” and the device didn’t have the same heft I usually see in our general professional offerings. Does this matter? I don’t think so, as long as it works as advertised.
  • Image Resolution and Quality: Wait… wait, these are somewhat of cons based on pros, all things considered. The device I tested (Atlona’s AT-HDVS-CAM-HDBT-WH paired with the AT-OME-RX11 – HDBaseT Receiver) offered a resolution of 1080p @ 60 Hz. Some would say, “but that’s not 4K… burn it!” But, in higher education, I’m not sold on 4K for standard classrooms as many of our capture systems and unified communications platforms can “only” capture or transmit 1920 x 1080 camera signals (there are obvious exceptions where 4K makes sense). The image quality is good for the price, and reasonable when compared with cameras that are approximate twice the price. At the price point, I wasn’t expecting a good image… and I was pleasantly surprised, so pro/con. It’s also worth reiterating that the cost of the device is very reasonable.
  • USB: This is a small thing, and somewhat unrelated to the camera, but I wish the AT-OME-RX11 HDBasseT Receiver had a USB video output that we could feed directly into a computer via a UVC driver for ultra-budget-friendly locations.

Final Thoughts: Is this the best PTZ camera on the market? No… yes… well maybe, as it really depends upon your goals and objectives. In the era of ever-shrinking AV budgets and a drastic uptick in the demand for video conferencing and lecture capture capabilities in classrooms, adding one or two $4,000+ cameras, not to mention the other devices necessary to integrate said cameras, is problematic. This camera may be a solid alternative to the costly, perhaps more professional, options on the market.


In the era of Covid-19, people are scrambling to find great document camera alternatives for home and in-office use. There is a wide range of devices available, but they generally come in two flavors, cheap and problematic and expensive, full-featured, and bulky. Today, I’ll give a quick review of the HUE HD Pro, a ~$99 USB document camera that bridges that gap.

First, the HUE HD Pro connects to a computer using a standard USB-A connector, so if you’re a modern Mac user, you’ll need a USB-A to USB-C dongle to get this working, so plan accordingly. Once you plug the HUE in, you’re ready to go, no batteries needed. I was able to fire up Quicktime/Zoom/etc. and see the HUE without installing any video drivers as the device leverages the built-in UVC driver available on all Windows and macOS devices. The image was initially very soft, but after a quick turn of the focus ring (did I mention that this is a manual focus camera), it was tack sharp. It’s worth mentioning, as I just did, that the camera focus is completely manual. While that may sound like a negative, I actually prefer setting the focus, as the camera doesn’t constantly “track” (going out of focus and back into focus as with some less expensive webcams) to obtain a good quality image. Considering it’s a document camera, the manual focus works great, as you only need to set it from time to time, and it doesn’t re-focus when it sees your hand.

The HUE HD Pro also has a mic… which is, well, OK at best. It’s passable, but if you are going to be doing any serious, long-term, document camera intensive teaching, you’ll probably want to use a different mic, or upgrade to a USB lav mic (ahem! – https://sites.duke.edu/ddmc/2018/01/04/the-movo-usb-m1-microphone/). You don’t buy this device for the mic, but considering you can also use the HUE HD Pro as a webcam (yep, just point it up from your document and manually refocus… and presto! You have a webcam!), the mic makes sense. Generally speaking, I wouldn’t buy this device if my primary goal was to use it as a webcam. There are plenty of higher quality webcams on the market, with autofocus, which has a better image and a lower cost. You buy the HUE HD Pro for the long flexible neck. But, it would work as a webcam in a pinch or if you are attempting to be ultra-mobile.

Image Quality: While I found the image very clear when sharing a hand-drawn diagram, I did notice that the camera picked up a good bit of flicker (aka, flicker happens when the alternating on/off of LED lights doesn’t match the frame rate of a camera). Overall, it wasn’t a major problem, but it was noticeable, and there really isn’t a way to eliminate the flicker, unless you are willing to swap out the lightbulbs in your environment (aka, not going to happen).

I’ve demonstrated this device about a dozen times, and the feedback is usually, “That’s exactly what I need, perfect… thanks.” It’s a simple device that performs a simple task, but as an educational professional will say, sometimes it’s the simple solution that solves the core underlying issue. Some AV professionals say that document cameras are going the way of VGA… but I still see a wide range of applications where a simple camera, sharing a hand-drawn diagram, is the best and cheapest option to convey a concept. I’ll take a document camera over an advanced touch screen most days.


  • No additional drivers required: The HUE HD Pro uses the native UVC driver included with Windows and macOS devices
  • Cost: At ~$99, this is a well-priced USB document camera considering how flexible the device can be
  • The image quality is good and when sharing written notes in a Zoom session, it looks great
  • Oh, and it has a small LED light, which is nice (note con below regarding the light)
  • It just works… and is simple enough for anyone to understand. Even > I < was able to use it!


  • I wish the articulating arm was longer, like 6” longer. Sometimes it is challenging to get an oversized sheet of paper in the camera frame, requiring that I place the HUE HD Pro on a book to “zoom out” as it really doesn’t have a zoom
  • Regularly, I found myself twisting the HUE HD Pro’s neck in odd ways to get my documents in the correct orientation. It would have been nice if there was an option to flip the image sensor on the device natively with a tactile button push (this may be possible using their included software, but I generally hesitate to install such software as it’s usually not supported all that well)
  • The light is… well, OK at best. They are not very bright and the color temperature of the LED lights isn’t ideal for every situation, but I’m a color temperature matching perfectionist
  • Flicker, if you have LED lights in your teaching space, you may see a noticeable strobing flicker. This can be problematic for users that are very sensitive to flicker. The guinea pigs, errr… remote Zoom users, didn’t mention it when I was demoing the hardware… but it’s there. I see it, and a few other AV folks would see it… but it’s by no means a deal-breaker

Help Clean Up Background Noise

As we’re all working with instructors that are recording at home, we can count on some of them not recording in the best surroundings for audio. We’ve tried several noise reduction plugins but I recently got the AudioDenoise 2 from CrumplePop and like its super simple interface. It has less “robotic” sound than other plug ins (like the one built into Final Cut) and feel that it’s worth the $99 price tag. Here’s an example:
