I wouldn't be worried about doing so (if I have to worry about a $100 doorbell being stolen/tampered with I've got bigger problems), but I'd [personally] prefer something that could be viewed on more than just my phone. I'd like it to be integrated with a CCTV/DVR system, so the video can also be recorded and viewed from anywhere in the world (e.g. browser). That said, I wired my home with CCTV cabling above my front door, so I'd actually be able to see the person(s) as they walk up. My doorbell is installed on a wall which is perpendicular to my front door, if I had a camera there, it would be looking at bricks 99% of the time which are on the other side, and would generally be looking at the side profile of the person(s) once they arrived at my front door. Obviously you can't do anything about the location of my doorbell, but I really can't either, as there simply isn't enough room on either side of the door for it to be installed there. That said, it probably wouldn't be a product that I'd be interested in - at least not for the home I currently live in...
