Do you have a pile of old Android phones laying around like I do? Maybe you have an older laptop without a cam? Or just about any other webcam ideas you may have.
It is a free app you apply to the device you plan to use as the webcam.
It took me about a half hour to get it configured and running.
Once running it was smooth with a clean frame rate on my wifi network. Which is the biggest plus you don't need to plug anything into your laptop or pc. You type in it's ip address (provided in the app), into your home computers browser address bar. The only note here is that internet explorer does not like this file system, you will need Google's free chrome browser or alike.
So drag those dusty old androids out of the closet folks they have a new life.
