Thanks for replying! I do realize Dropcam is a waste of money, that's why I was looking for alternatives. Right now I have my eye on the Samsung SNH-P6410BN, because it has both local storage on SD card and uploads to Google on motion triggers. The problem is, the area I want to use it in (facing the street) has too much going on and makes visual motion detection useless. Even with "motion zones" I get a lot of false positives because of shadows/trees swaying.
Dropcam tabs seemed like a perfect solution right out of the box, I could simply attach it to a gate or door and only when the object moved would it trigger a notification. I tried googling for different things, including "dropcam tabs alternatives" and "security camera with wireless sensors" but got nothing relevant. Surely there must be something out there? My old Zmodo CCTV system had a wired alarm input in the DVR box, but wireless sensors would be even better.
