All you need to do is use the appropriate menu option in your chosen video chat app to select the camera. In Skype, this would be Tools Video settings, where you’ll find the Select webcam dropdown menu.Select your Android webcam from the menu, click Save and you’re done.For devices with two cameras, tap the Settings button on the mobile app and check the appropriate box to switch to the camera you want to use.
Arguably the best — perhaps really, the only — choice you should make is to install Droid Cam, an Android app that turns your smartphone (and if you have a good device for grabbing it, your tablet) into a handy, portable webcam.
Once launched, you’ll be invited to input the IP address for your Droid Cam.
This should be easy to find, just run the app on your Android and it will be displayed, as well as the port number.
When you’re ready to proceed, click Start to begin streaming.
The mobile app will then send the image from your phone’s camera to your computer.
You’ve setup a webcam and it is streaming images from your phone’s camera to your computer.
