Yes and no. Installing the Snapshot SDK always requires Internet connection, since you have to download the files from the Internet. Thereafter, a subscription plan to Snapshot SDK will “call home” a few times a month to validate the subscription. No images are sent, but only a few bytes of data are sent to validate the subscription.
So flakey, intermittent Internet is OK for the Snapshot SDK subscription. If there is absolutely no Internet available at all, then you can go with a Perpetual License of the Snapshot SDK.
Please contact us for more information about a Perpetual License for the Snapshot SDK.
