Hi MrHobbs,
Thanks for posting here in the community. I understand you're looking to confirm if the Nest Cam Outdoor (2nd gen) mount fits with your first-generation Nest Camera. Help is here!
The mount for the Nest Cam Outdoor (2nd gen) (which can be the Nest Cam (outdoor or indoor, battery) or Nest Cam Outdoor (wired, 2nd gen)) is not compatible with the first-generation Nest Camera. Google introduced new hardware designs for the 2nd generation cameras, and the mounting systems are different between the two generations.
If you are replacing a first-generation Nest Camera with a 2nd generation model, you will need to remove the old mount and install the new one that comes with the Nest Cam Outdoor (2nd gen).
You can find all the necessary information, including specific details about different Nest camera models. Refer to this article: Technical specs for Google Nest cameras.
Let me know if you have any other questions.
Best regards,
Melany
