Got the answer to your question about uploading footage from security cameras to net…facebook 
On news now there’s one about a landlord that uploaded his live footage to facebook and caught a burglar on camera :lol:
Cool 
You can use any web-cam and software like: Active WebCam.
This takes either video footage or stills when movement is detected and uploads it to your email account.
Someone caught a burglar that way despite them taking the PC.
