I am quite new at this, so be gentle.

For streaming/photos from home for monitoring the house/pets while on a trip, is the webcam generally the preferred method? One webcam per computer, or can you do more? Limit?

What about buying several tablets and enabling their cameras, over the wifi?

I have looked at the 8- or 16-camera security machines (Lorex, Swann, Q-See, etc.), but don't see the need in my case for a DVR "base unit" particularly, which appears to cost a decent amount. Or does that give you added power/flexibility?

Any other recommendations? Thanks.
