Great article. My favorite part is that the author advises against overly complicated setups and has some very realistic recommendations instead:<p>&gt; The strange video you see at the top of this post was filmed with this setup. One that I actively recommended against to any fellow remoter. Particularly folks who aren’t into photography or videography. It’s cumbersome, complex, and requires constant fidgeting to keep the camera on, obtain a consistent color temperature, or prevent automatic focus hunting due to shallow depth of field.<p>This is a common theme among people with overly complicated setups: Looks and sounds great when it works, but they&#x27;re fighting with their setup in every other meeting: Focus issues, automatic power off problems, photographic cameras overheating because they weren&#x27;t designed for long streams, audio issues as they work to select the microphone they want instead of something else, and so on.<p>This page recommends two excellent webcam-style USB cameras that won&#x27;t deliver the professional-looking blurred background images, but they will just work when you plug them in and they won&#x27;t be full of surprises. That&#x27;s more valuable than a blurred background or crisp 4K video through expensive lenses when you&#x27;re just a small H.265 compressed square on someone&#x27;s screen.

All that effort, then comes the actual video call software and blows the quality to smithereens, and you&#x27;re back to yelling at a speaker connected to the mic socket and recording using the GameBoy camera add-on dipped in molasses.<p>It&#x27;s really frustrating, I also cared to set up a decent input, but all of Google Meet, Slack, and Zoom have terrible terrible compression.

The Shure SM7B is a very popular microphone, but for a remote meetings use case I&#x27;d suggest starting with a quality XLR capable audio interface (this is a requirement for the 7B anyway) and a Shure SM57 mic.<p>The reason I suggest not starting with an SM7B is because this microphone is expensive at nearly $400, and requires high quality mic preamps to get a proper signal out of the mic (often people add a $150 cloudlifter) which adds to the expense.<p>The SM57 on the other hand is an excellent XLR dynamic microphone, used on countless recordings and live sound applications. It is super durable, and can be purchased used at around $50.<p>Plus Shure makes an optional $20 foam windscreen for the SM57 called the &quot;A2WS&quot; which helps filter out pops and plosives, and makes the mic look similar to a 7b.<p>There are many comparisons available on youtube to see if you can hear a $350 difference yourself, for example <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=PFba93OLLig" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=PFba93OLLig</a>

The audio comparison is disingenuous because the levels are not normalized in any way. Once you normalize the levels the difference between Macbook and Shure, while noticeable, is not really something I&#x27;d call &quot;radical&quot;.

Ok, one reality I find this does not address is that not all of us have a nice silent space to work in, and most Mic&#x27;s don&#x27;t perform well in that space.<p>In my case, I live in a one room Studio Loft with my wife, who is in meetings all day and is quite a loud speaker. Pretty much any boom&#x2F;desktop Mic I&#x27;ve tried is also really good at picking her up.<p>My current workaround is to use a unidirectional headset microphone[1], But would love other ideas, as cable management is a bit cumbersome.<p>[1]<a href="https:&#x2F;&#x2F;www.amazon.com&#x2F;dp&#x2F;B07D49N8C4" rel="nofollow">https:&#x2F;&#x2F;www.amazon.com&#x2F;dp&#x2F;B07D49N8C4</a>

I use an S55H hanging from a pulley, boxing ring-style, just high enough to be out of the video frame unless I&#x27;m trying to show it off, into a Cloudlifter and Scarlett Solo. As a veteran of several remote-first company audio wars, I have gotten many compliments on this rig. All this to say, it&#x27;s hard to go wrong with a condenser mic and a cloudlifter into a decent audio interface. My camera game (iMac Facetime camera) is however fairly wack.

The author points out that remote working is solving the &quot;expensive places to live&quot; problem, yet moved to a studio in Paris which are awfully expensive. I am quite of puzzled by this.<p>Of course, if the author gets the North American salary instead of the European one, while living in Paris, then things might work out financially.<p>I moved in the deep suburbs of Paris because rent and apartment prices are a no go for a single income person, even in tech.

As someone who has been working remotely for almost a decade at this point, I will say straight out that a built-in camera on a recent laptop is mostly just fine. What you need to concern yourself with is &#x2F;position&#x2F; of the camera and &#x2F;lighting&#x2F;.<p>Do these three simple things to make your video better:<p>1. Get a laptop stand that raises your laptop so your eye level is towards the center of the screen. Not only does this improve ergonomics, it improves the positioning of the camera for video.<p>2. Get a lamp that you can move the head on and point it at the wall behind the laptop (assuming it&#x27;s white-ish in color) to provide reflected back light at your face from behind the camera, and then add as much ambient light as possible in the room emanating from the corners (smaller rooms are easier to light). You don&#x27;t need anything fancy, although yes a ring-light is probably &quot;better&quot; you can get by with cheap floor lamps from Walmart and some &quot;daylight&quot; color temperature bulbs.<p>3. Make sure all the lightbulbs in the room are the &#x2F;same&#x2F; color temperature, whatever that happens to be, but preferring &quot;daylight&quot; if you can.<p>Just these changes will MASSIVELY improve video quality on conferences, and for most people wouldn&#x27;t even necessarily require buying anything additional except possibly light bulbs (you can makeshift a laptop stand, and move lamps from other rooms if it&#x27;s an especially important meeting &#x2F; interview you are preparing for).<p>For audio, nothing beats a microphone on a boom, but any good quality USB headset with a built-in boom microphone will get pretty close, so don&#x27;t sweat this so much. The main thing is that you should NEVER be taking a call using the built-in speakers and microphone in your laptop... it sounds horrible and picks up a lot of noise.<p>The only laptops I would never use the camera on are Dell laptops that inexplicably chose to put the camera near the keyboard so it&#x27;s staring up the person&#x27;s nose the entire time.

I got an Avaya Huddle Cam, like the kind in many large enterprise conference rooms for $200 off amazon, its plug and play and has all sorts of zoom and pan features, HDMI output, stereo microphones and is 4K and because its Avaya, and regular folks dont seem to know about them, they&#x27;re not really more overpriced then normal because of the pandemic or shipping. Also got a $35 Monoprice branded usb microphone does quite admirably. My co-workers have complimented me that it sounds very clear. The best part is that they are all plug and play and work on Linux&#x2F;Windows&#x2F;Mac with no additional downloads or drivers.

I&#x27;m pretty interested in this: <a href="https:&#x2F;&#x2F;opalcamera.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;opalcamera.com&#x2F;</a><p>There&#x27;s been a vacuum in high quality web cameras for a while, most of the market has just been junk.<p>A good microphone is totally worth it too. I&#x27;m not sure why after over a year of pandemic and remote work many are still using their 720p webcam in a dark (sometimes backlit) room with the crappy built-in mic. If you&#x27;re making good money invest in a decent set up - with mostly remote comms, it matters more than you think.

1. Don&#x27;t we need a good internet connection (&amp; VPN software if needed) to pair up with this setup?<p>2. Also the bandwidth of our video conferencing service (eg. Zoom)?

If you have an office and can put things on speaker phone, the Logitech BCC950 Conference Cam is well worth the money (it’s $164 on Amazon right now).<p>The camera quality is good (a little short but can be put on a riser), the audio quality is good. The noise cancellation is good.

Wondering how the 2021 MacBook Pro camera stacks up to the 2019 one. I did my first Zoom call with my 16” M1 Max yesterday and the quality seemed to be quite a lot better (although I coincidentally improved the lighting near my desk a bit, as well).

&gt;narrow pickup microphones with live headphone monitoring<p>Does someone know why this matters?<p>None of his samples show him with headphones, so what are they used for?

Can someone suggest a camera that is similar to the Sony A6000 mirrorless he demos but not as expensive?

My setup went through a lot of iterations over the lockdowns trying to build a high-quality setup in a small inner-city apartment; I&#x27;m almost happy now, but it&#x27;s been quite a journey that I expected to be much easier and a lot less of a rabbit hole, but oh well at least I learned a ton. Also, why are webcams that bad? Given what low-tier phones can do with their back cameras, it&#x27;s really weird just how freakishly bad webcam image quality still is on a lot of models.<p>As for some of my learnings:<p>Cameras: Using an external camera is important, looking downward into a laptop camera isn&#x27;t very flattering to begin with, and it makes me uncomfortable. As with an ill-fitting suit, it makes me less confident. So I tried using my Fujifilm X-T4 with a HDMI capture device, since I already had that; a Logitech StreamCam, a Logitech C920 (or C922, not sure), a Razer Kiyo Pro and several cheap 720p webcams. The X-T4 wins in the image quality department (unsurprisingly) hands-down, but you have to run the audio through it as well or use a super low-latency capture device or else the image may lag just a small-but-perceivable bit and make the result feel pretty uncanny-valley-ish. It&#x27;s a big hassle to set up before every meeting and leaving it on a free-standing tripod is an expensive accident waiting to happen. Would not recommend unless you must have the very best quality you can get (and have compatible microphones and good lights).<p>I&#x27;ve found the Logitech Streamcam to be pretty solid in terms of image quality. Don&#x27;t count on Logitech&#x27;s software if you&#x27;re on a Mac, because part of the functionality is outright missing or broken, another part is availably only through a virtual webcam the software creates that won&#x27;t work with most apps, and the whole thing will eat CPU like crazy, I&#x27;ve uninstalled it pretty quickly. Instead I use Webcam Settings [1], which can set the most basic parameters (exposure, focus, pan&#x2F;tilt&#x2F;digital zoom, backlight comp, anti-flicker, white balance) directly on the camera, which works a lot better. I digitally zoom it on my head a bit as it&#x27;s quite wide, and that doesn&#x27;t seem to hurt the image quality meaningfully as far as Slack&#x2F;Zoom&#x2F;Teams calls are concerned (might be different if you stream to Youtube at full res, but I never do). All StreamCams I received mid-2020 had focus issues, but these can be fixed relatively easily by cracking them open and changing the pre-set focus manually (voiding the warranty of course), and they seem to have fixed their QC since anyway, so getting one of these should be a pretty safe bet.<p>The Razer Kiyo Pro is great as well, with a very nice image, but it&#x27;s even wider, and last I checked there was no macOS software at all. It still works well on macOS, though, you just can&#x27;t use anything that requires Razer software, but it&#x27;s compatible with Webcam Settings, so I&#x27;m fine. Using it on the living room TV nowadays for calls with friends and family and it works really well in that function as it&#x27;s really wide-angle, so I could imagine it would work well for small meeting rooms. It&#x27;s pretty big (too big for my desk setup, actually) and the microphone isn&#x27;t great (you definitely need an external one no matter what), but its image quality is really great, considering it&#x27;s a webcam. Very good low-light performance as well, great colors, looks more like an actual digital camera than a generic webcam.<p>I didn&#x27;t like the Logitech C92x I tried at all. Grainy, bad low light performance (not that important as I have lighting, but still), slow to react to lighting changes, ugly, washed-out colors even when lit properly, I sent that one back right away. It was from Amazon so it might have been a fake, and there seem to be several models that are near-identical but differ greatly in image quality, so your mileage may vary.<p>Next, lights. People are having quite a lot of success with ring lights, but I have my desk against a wall with shelves, so placing a ring lights at the proper distance doesn&#x27;t work well, and I find they&#x27;re eyesores. I currently use approx. six meters of Hue-compatible LED strips with warm&#x2F;light diodes in addition to RGB hidden behind the monitor and shelves, at a press of a Hue switch all come alight and give me a lot of pretty clean, bright indirect light bounced of the wall, and it&#x27;s essentially invisible unless turned on. Still working on synchronizing the light color and intensity with the outside light coming in through the window, but being Hue-compatible makes that pretty straightforward in theory.<p>People keep preaching that lights and microphone are the most important things to get right, and I guess it&#x27;s true. Turning on those LED strips is like a 600% image quality boost even in a relatively well-lit room using a decent camera. If I were to re-do this with a free-standing desk, I&#x27;d probably look into using softboxes.<p>Finally, microphones. Especially when part of a grid of participants in a call, the part of you that gets to make the biggest impact is your voice. It&#x27;s also a pretty visceral kind of impact; I think there was a piece on that on HN a few months, back, essentially describing how being hard to understand makes people viscerally like you less, so as with lights, nailing this goes a long way. I use an Elgato Wave 3 on a short horizontal arm at around face-height that I can rotate off to the side; since it has a built-in pop filter, it&#x27;s a pretty compact package and it&#x27;s fine to have it dangle around at head-height, and since it has a kidney characteristic, I can angle the part with the least sensitivity towards the keyboard to really reduces typing noise by a lot. Before the Wave 3, I used the much less expensive Behringer C1U as well, and while you might want a pop filter with it, it&#x27;s just fine as well, no gripes with it. Almost any half-decent microphone is going to be a big improvement over webcam microphones, let alone bluetooth headsets, just make sure you decouple it from your desk (there are lots of inexpensive stands and arms that will do this).<p>If you need to get up and draw things on a whiteboard or the like, I find the Røde Wireless Go and the corresponding lavalier microphone work like a charm, but it picks up mechanical keyboards very well. For my Macbook, I had to add a USB sound interface (a cheap one worked fine) and one of these USB isolator thingies to get rid of a persistent whine when keeping the receiver plugged into USB-C for power. I tried cheaper chinese transmitters that had their max gain so low it was borderline unusable, but I find the Røde Wireless Go (I) to be very solid. Good range and battery life, too.<p>I&#x27;m still working on getting the background right. I can&#x27;t rely on background removal functionality as I sometimes have to use software that doesn&#x27;t have this, and there seem to be no standalone solutions that don&#x27;t hog half the CPU. I&#x27;ve played around with OBS a bit, but it introduces a perceivable delay that I feel makes it a bit harder to take part in fast-paced discussions, so nowadays I try to avoid it. I can&#x27;t place my desk so my actual background is nice, so I currently use a simple molton fabric backdrop on a rod of bamboo that can be attached magnetically to two little magnets dangling from the ceiling and can be set up and taken down really quickly, rolled up and stashed away out of sight. It works quite well, but it&#x27;s an opaque white – some structure in there might be nice. As I said, still a work in progress.<p>Apart from this, I&#x27;m quite happy with my current setup, and I&#x27;ve received unsoliticed positive feedback as well, so I seem to have done a thing or two well enough. Not sure if the result is actually worth all the effort I&#x27;ve spent (probably not), but it&#x27;s been a (more or less) fun rabbit hole&#x2F;lockdown project.<p>1: <a href="https:&#x2F;&#x2F;apps.apple.com&#x2F;de&#x2F;app&#x2F;webcam-settings&#x2F;id533696630?mt=12" rel="nofollow">https:&#x2F;&#x2F;apps.apple.com&#x2F;de&#x2F;app&#x2F;webcam-settings&#x2F;id533696630?mt...</a>
