Dropcam has just announced that they are halting work on Tabs, a sticky movement sensor that can be placed anywhere in your house to let you know if a door, gate, or window is open. The reason they gave is they’re now working on their projects with Nest. If you remember, Nest acquired Dropcam a while back. There is no word if Tabs will ever be made so those who pre-ordered will be getting full refunds in the coming weeks.
