How can I integrate my mobile phone into my computer as a webcam?

At the moment decent webcams are not available and the price for a 70 Euro Logitech webcam has more than doubled.

Instead, simply use your mobile phone camera as a webcam replacement. Here is a list of possible solutions:

- Iriun (Phone: Android/iOS Computer: Mac/Windows )  (High resolution, sometimes crashes on OSX)
- Epoc (Phone:  Android / iOS Computer: Mac/Windows) (Low resolution)
- iVcam (Phone: Android/iOS Computer: Windows)
