Everyone is after monthly fees. Many software like photoshop charges monthly fees. I was surprised when BI was a 1 time payment. Good guy not charging monthly/early when he could have easily.
FD: I'm one of the Camect founders.
Camect's subscription isn't required. You get a perfectly usable system with functionality comparable to BI (but targeted at a less sophisticated user) with no subscription. BI does give you alert delivery, whereas we don't ... but on the other hand we give you real local object-detection-based AI and BI does not.
If you get object detection from Sentry, and automatic software updates from BI, I believe you'll have to pay more per year than you do with Camect's $60/yr subscription (but that was not the point of our fee). You'll also be sending your data to the cloud for the Sentry AI, whereas ours is 100% local.
Our monthly fee covers things that depend on internet infrastructure that is an ongoing cost for us -- things like WebRTC-based remote access, alert delivery (email, Telegram IM, or app notification), backup to services like Dropbox/Google Drive, etc. We include these services for two cameras with the purchase of the box, but if we don't charge for them, they aren't going to be sustainable long-term as we're selling the hardware as cheaply as we can -- and we're not in the business of making money by selling our users' privacy.
Re: Integrations with Nest and Arlo ... We want people to be aware that (like anything else with a cloud camera) the manufacturer can cripple them at any time but we'll keep them going as long as technically feasible. We are serious about keeping them going though.
The point of supporting these cameras is to give people stuck on Nest/Arlo/Ring a way to see what they can get from Camect, and encourage them to switch to regular IP cameras eventually because they'll get better quality, lower cost, and no dependency on the cloud while keeping the same user experience.
The point of Camect as a whole is to provide an experience comparable to (and hopefully better than, at least as far as the AI is concerned) Nest/Arlo/Ring for users who currently have no other choice. Setting up a PC and configuring BI is quite beyond the technical reach of many people out there.
