Welcome back @bkbonner!
I definitely like this idea.
There’s a Wishlist item for computer viewing here:
You might want to add you idea there. You may be able to do this using APK Mirror, but I don’t have any experience with it and I’m unsure how stable it is.
If you only need to view the cameras, you should try TinyCam. It can be unstable at times , but works well for watching the cameras. You can purchase cloud recording services from TinyCam, but it’s not worth it if you already use Cam Plus on the SD card.
Is there a trick to using the tinyCam app? I’ve downloaded it, but it doesn’t seem to do anything. I have a camera for keeping an eye on my foster kittens and I’d really like to be able to open this up on my computer while I’m working.
