You can use your Android device as a PC webcam by downloading the Smart Cam app and desktop client.

Many homes have not one but several cameras aimed inside the home – and that’s not including the ones inside smartphones and tablets.
As baby monitors and surveillance cameras have boomed in popularity, so have the risks – as highlighted by a Russian site showing off feeds from thousands of unsecured cameras.
Depending on your strategy, a microphone might also be needed, but not required.
In fact, many animal live streams are done with no audio at all.
First time making a suggestion so let me try to sell it a bit. Great move Microsoft offering consumers a choice in the matter! Therefore some apps(mainly Skype) have less value as these user with no Kinect cannot video chat obviously.
Now, the clear course of action is to sell Kinect standalone, but Im certain people who bout this console variant do not want Kinect period!
Now, I usually have an actual HD web camera which I hook up to this laptop when I do chat with people on Skype, but today, I didn't have my HD camera with me, so I was trying to use the web camera on the laptop itself, and it doesn't work.
I have errors when trying to install the driver's from ASUS's website, and am kind of worried to here if the camera itself is fried, as I never drop this laptop, as I take care of it as if it was an 00 laptop.
What if these users already have Skype ready alternatives they use on a regular basis?
Would it make sense to buy Kinect just to do what any high end web cam today can do on Skype?
As such gadgets have got cheaper, manufacturers have cut corners – and that means if you don’t pay attention, you could be at risk. There have been several cases where cybercriminals have been able to access video feeds from baby monitors – or worse.
