网络摄像头工作原理

I've been a remote worker and an occasional YouTuber for well over a decade. I'm always looking for a better setup because the goal is clear - how can I interact with you and my co-workers in a way that has high-enough fidelity that I don't need to drive to Seattle every week!

十多年来，我一直是一名远程工作者，偶尔也担任YouTuber。 我一直在寻找更好的设置，因为目标很明确-我如何与您和我的同事保持高度的忠诚度，而我每周不必开车去西雅图！

I believe if my camera is clear and my audio is clear than I can really have a remote relationship with my team that is effective and true.

我相信，如果我的摄像机清晰，音频清晰，我与团队之间就可以建立有效而真实的远程关系。

Everyone has a webcam these days and can just get on a video call and have a chat - but is it of sufficient quality that you feel like you're really having a good conversation with folks and truly connecting!

如今，每个人都有一个网络摄像头，可以进行视频通话并进行聊天-但是它的质量是否足以使您感觉与其他人进行的是很好的交谈并真正建立了联系！

Here's a shot of my setup during a meeting I'm in here at Microsoft:

这是我在Microsoft参加的会议期间设置的快照：

Here's my thoughts on Good, Better, add Best set-ups for remotes and YouTubers without spending thousands.

这是我对“好”，“好”的想法，无需花费数千美元即可为遥控器和YouTuber添加最佳设置。

好 (Good)

• 

  The Logitech C270 Webcam can be gotten for as little as $20 or less! It's wholly adequate with enough light.

  Logitech C270网络摄像头 只需20美元或不到20美元即可获得！ 有足够的光线就足够了。

  • It only does 720p and it's USB2 so I can't enthusiastically recommend it but it's OK again, if you throw light at it. In the dark is just a webcam.

    它只支持720p，它是USB2，所以我不推荐它，但是如果您轻拍它的话，也可以。 在黑暗中只是一个摄像头。

• The Logitech USB Headset H570 is decent, as is the lovely Jabra UC Voice corded headset. I prefer the Jabra because it only covers one ear and doesn't give me the "two covered ears" claustrophobic feeling.

  Logitech USB耳机H570和可爱的Jabra UC Voice有线耳机一样不错。 我更喜欢Jabra，因为它只覆盖一只耳朵并且不会给我“两只覆盖的耳朵”幽闭恐惧症的感觉。

  • To be clear - audio quality matters. Any crappy headset (or quality one as above) will ALWAYS be better than your webcam's default or your laptop's default. Always. Mics need to be closer to your mouth to sound good.

    要明确-音频质量很重要。 任何cr脚的耳机(或以上质量的耳机)总是比网络摄像头的默认值或笔记本电脑的默认值更好。 总是。 麦克风需要靠近您的嘴才能听起来不错。

• Small webcam Ringlight.

  小型网络摄像头Ringlight 。

  • Light light light. Webcams, especially cheap ones NEED LIGHT. It feels weird and I get it but the quality is SO MUCH BETTER with some decent fill light. Get a ring light that's powered by USB and use it on calls. Yes, it looks ridiculous but it WORKS.

    轻轻轻。 网络摄像头，尤其是便宜的网络摄像头，需要轻巧。 感觉很奇怪，我知道了，但是质量很好，有一些不错的补光灯。 获取由USB供电的环形灯，并在通话中使用它。 是的，它看起来很荒谬，但是可以。

更好 (Better)

How can we improve on the GOOD setup. Clearer videos and better sound/sound feel.

我们如何改善“良好”设置。 更清晰的视频和更好的声音/声音感觉。

Some folks feel the Logitech Brio is overhyped and I think that's fair. It's a "4k" camera that's not as impressive as it should be. That said, it's a solid camera and arguably the best Logitech has to offer.

有些人认为Logitech Brio被夸大了，我认为这很公平。 这是“ 4k”相机，效果不佳。 也就是说，这是一台坚固的相机，可以说是罗技必须提供的最好的相机。

If I could suggest a middle of the road solid "BETTER" setup for a remote worker, I'd recommend these

如果我建议为远程工作人员设置一个稳定的“更好”设置的中间方法，则建议使用这些方法。

• Logitech Brio - solid 1080p 30fps

  罗技Brio-稳定的1080p 30fps

• Logtitech USB Headset

  Logtitech USB耳机

• LED Light ring

  LED灯环

The lights are the magic.

灯是魔术。

Now, moving beyond USB headsets, I love adding speakerphones - not for the mic, literally for the speaker. I love the Plantronics Portable USB Speakerphone. Requires no drivers, it just shows up as a mic and speaker automatically. I have it front and center in front of my monitor and I use it every day. It makes me feel like my Home Office is a real Office somehow.

现在，除了USB耳机之外，我还喜欢添加免提电话，而不是用于麦克风，实际上是为扬声器。 我喜欢Plantronics便携式USB扬声器电话。 不需要驱动程序，它会自动显示为麦克风和扬声器。 我将它放在显示器的正前方和中央，我每天都在使用它。 某种程度上，这让我觉得我的内政部是一个真正的办公室。

If conversations are private I'll use the headset above for the audio but when I want the sound to "come from the monitor" I'll SPLIT the audio. This is a pro tip. You can set up the Mic input as the headset mic and the Speaker output as a Speakerphone (or your main speakers). I like using the Speakerphone for voice and keeping the computer's output as the main speakers. Having this separate of voice and computer sounds is a small trick I play on myself but it helps to create a sense of location where the remote video person comes out of separate speakers.

如果对话是私人的，我将使用上面的耳机作为音频，但是当我希望声音从“监视器”发出时，我会拆分音频。 这是一个专业提示。 您可以将麦克风输入设置为头戴式麦克风，将扬声器输出设置为免提电话(或主扬声器)。 我喜欢使用免提电话发出声音，并保持计算机的输出作为主要扬声器。 将声音和计算机声音分开是我自己玩的一个小技巧，但这有助于营造一种感觉，使远程视频人员从分开的扬声器中出来。

最好 (Best)

Let's spend a little bit of money, but not so much that we break the bank.

让我们花一点钱，但不要花太多，以免破坏银行。

I'm going to make my own webcam. Rather than a plastic of the shelf single webcam, let's take an actual mirrorless camera - the kind you'd take to a photography class - and make it a HIGH QUALITY webcam.

我要制作自己的网络摄像头。 让我们使用一台真正的无反光镜相机(您将要在摄影课上使用的那种相机)，而不是像架子上的单个网络摄像机那样塑料制成，并使其成为高品质的网络摄像机。

We need a great camera and it needs to support HDMI out. The camera also needs to be able to stay on all day long, not overheat, and it needs to run on AC power (not on battery).

我们需要一台出色的相机，它需要支持HDMI输出。 摄像头还需要能够整日保持不过热，并且需要使用交流电源(而不是电池)供电。

Here's a list of cameras that have clean HDMI out and can stay on all day. You might have one of these cameras in your closet! I like the Sony A6000 and here's its characteristics.

这是一台干净的HDMI输出并且可以整天使用的相机列表。 您的壁橱中可能装有这些相机之一！ 我喜欢索尼A6000，这是它的特色。

• Sony A6000 - I found this on Craigslist for $300.

• I need a "dummy battery" for this camera. Turns out this is a whole class of thing you can buy. Who knew?

  我需要此相机的“虚拟电池”。 事实证明，这是您可以购买的一整类东西。 谁知道？

• This camera has micro-HDMI so I need a micro-HDMI to HDMI cable.

  本相机具有微型HDMI，所以我需要微型HDMI至HDMI电缆。

• Now this is just a loose camera, so how I will mount it on my monitor?

  现在这只是一台松动的相机，那么如何将其安装在显示器上呢？

  • I like mounting it INSIDE the Ring Light. If you don't want the light you can just get this clamp mount.

    我喜欢将其安装在环形灯内。 如果您不想要照明灯，则只需安装此夹具即可。

  • Or you can do what I did - get the CLAMP then the LIGHT and then put the CAMERA in that like a sandwic

    或者，您可以做我所做的事情-先获得CLAMP，再获得LIGHT，然后将CAMERA像sandwic那样放入其中

    

• This camera and cameras like it output HDMI and I need that HDMI to be inputted into my computer and I want the HDMI output of the camera to look like it's a regular Webcam. The magical device that does this for us is the Elgato CamLink 4k. It's literally a little stick with HDMI input on one end and a USB3 on the other side. It took 5 minutes to install.

  这款相机和类似的相机输出HDMI，我需要将该HDMI输入到我的计算机中，并且我希望相机的HDMI输出看起来像是普通的网络摄像头。 为我们做到这一点的神奇设备是Elgato CamLink 4k 。 从字面上看，这有点像一根棍子，一端是HDMI输入，另一侧是USB3。 安装花费了5分钟。

  • This device also has the added benefit of being a generic "capture card" if you want to record or broadcast your gaming consoles OR other computers!

    如果您要录制或广播游戏机或其他计算机，此设备还具有成为通用“捕获卡”的额外好处！
