Droid cam

DroidCam s a bit easier to install and work with compared to IP Webcam. But it seems like there are more options available in IP Webcam; with DroidCam the free version doesn’t allow you to change the video format or resolution. Droidcam works with Gmail chat and Skype. I could not get the USB option to work, as you need to forward ports on your computer (I can’t do this with my current firewall). Wi-fi and Bluetooth work fine. The audio works but its a bit choppy — not ready for prime-time yet.

In Skype or Gmail chat video settings select “DroidCam” as the source.
SmartCam
This app works via Bluetooth (with audio and video – but the audio is a little choppy) and wi-fi. You can change the resolution, unlike DroidCam, so it gets a thumbs up there.
