Hello! Arenti Laxihub P2F camera can be used with the cloud service or SD card. You can follow the instructions to set up a 3-month free cloud service (offered by AWS), fees will be charged after that. Or you can use an SD card (storage up to 128GB) to get your data saved locally. If you have any other questions, please contact us anytime. 

Yes, our cameras can flip the image, so you CAN mount the cam upside down. If this is preferred, simply go into the "Settings" in your app, find and click the "180 degrees" and the image will be inverted to the new upright image. If you decide to change the cam to the upright (physically) mounted position, just turn the same 180 degrees setting (within "settings") and the image will flip to match the cam mounting perspective.
