Pc Surveillance Camera Can I Use My Digital Camera As Surveillance Camera And Hook It Up To Computer Or TV ?

Can I use my digital camera as Surveillance camera and hook it up to computer or TV ? - pc surveillance camera

I mean digital camera (Canon S3 IS) as a surveillance camera or security camera and view on my PC or TV, is it possible or not?
and it was a program to make it alone or using a camera or a webcam?
If so, how can I explain, please.
Thanks
