Google Nest Cam Indoor and Dropcam Pro stands are interchangeable. However, older Dropcam models, like Dropcam HD, will only fit their own stands.
While the Nest Cam Indoor and Dropcam Pro stands are
interchangeable, there are some key improvements to the Nest
Cam Indoor’s stand aside from the slimmer design:
Screw mount: The threaded hole in the stand's neck lets you
attach your Nest Cam Indoor to any standard 1/4"-20 tripod
mount or even a bolt with the same thread size. With this option,
you can securely hold your Nest Cam on curved surfaces and
other odd places where using the flat base isn't possible.
Magnet: The rare-earth magnet in the stand's base gives you
even more mounting possibilities on metal surfaces. Its strong
grip will easily hold your Nest Cam Indoor in any position, even
upside down. Now you can mount to almost anything made with
steel (shelves, furniture, and even some appliances) without
marring the finish or drilling holes.
Cable clip: The built-in cable management lets you easily route
Nest Cam Indoor's power cord for a clean looking installation.
