Webcam Surveillance Software? - webcam motion detection software

What is a good webcam surveillance software, motion detection, email alerts, streaming video and audio, multiple cameras.
I do not care whether there is a freeware or have as its not too much to buy.

Every search I come with the software crap it always crashes. The software recognizes not collapse even crappier, and just stinks.

I let my secondary computer, 24 / 7 and you want to use for the surveillance of a house.

What do you know it?
