Security system

I am working on a raspberry pi based security system, which includes a camera, motion detector, and lock. The motion detector and lock are pretty easy to get to work with blynk, but the camera is the tricky part. It doesn’t even have to be a good feed, 1fps 480p is good enough, so long as I can see what is going on. Can anyone help me figure out where to start?
thank you
