 I have four smartphones in my hand. Two iPhones and two Android phones. I'm going to connect all four of them as web cameras on my computer and use them at the same time. Let me show you how. Smartphone cameras are getting incredibly powerful so it makes sense to use them as a webcam. I'm currently recording this using a Logitech Brio 4K camera. Considered one of the best web camera. Let me switch to the Samsung S20 which I have set up as a web camera and this is the view from the Samsung S20. Let me show you how to do this. We need to install a software on a laptop and an app on the smartphone and very important both the devices must be connected to the same Wi-Fi for this to work. The software that I'm going to use is called Irian and the reason I'm going to use it is because first of all it's free and second it allows me to set up up to four smartphones as webcams. Start by downloading the software whether it's for your Windows or your Mac and even for Ubuntu. Since I have a Windows PC I'm going to install the Windows software. Click on it and it will download the installation program on your PC. Click on the downloaded file and install the software on your laptop. During the installation process you can choose how many web cameras you want to set up simultaneously. If you plan to use only one smartphone as a web camera you can choose one. The software supports up to four web cameras at the same time and that's amazing. For a demo let's set up four cameras because I have four smartphones. Click next and click install. Once the software is installed you can launch the application. In my case since I had set up four cameras I can see four tabs camera one to camera four. As of now nothing is displaying on the screen because no cameras are connected but let's go to the next step connecting the cameras. To install the app on your smartphone go to your app store and search for Irian. Let's bring up the smartphone view. This is the view from my phone. I can go to play store, click search and download the Irian 4K webcam for PC and Mac. In my case the app is already installed so I can simply click on open and I can see an alert showing me that my smartphone is now connected as a web camera. So this is the camera view and this is what my computer sees as a webcam. You can choose the resolution by clicking on this arrow and choosing one of the presets based on your needs. In my case let's go for 1920 by 1080 which is HD resolution. If your smartphone has multiple cameras like most of the modern smartphones Irian supports choosing which camera you want to use. For example if you want the wide angle and voila this is the wide angle view from the Samsung S20. Let me set up all the four cameras and get back to you. I've connected all the four smartphones to my PC and they are all live. Camera 1, camera 2 view which is behind me, camera 3 to my side and also I have camera 4 which is also to my side. With all four cameras on let's see how we can use them in an online meeting. Let me start zoom. This is my zoom client. If I click on the arrow next to the stop video icon I can see all the cameras listed. So if I want to change my view let's say to camera number 2 which is behind me it will change. If I want camera number 3 in an online meeting this could be quite helpful to show different views to the audience and that's how you can set up a smartphone or multiple smartphones as web cameras and switch between them with a simple click. Have fun in your next online meeting with your smartphone as your webcam.
