Forgive me if this is off-topic but I recently discovered the Mac program SecuritySpy and I'm considering it as a replacement for IPTimeLapse. I too use Macs for day-to-day stuff but I also run a 'headless' Win10 box on my home network just for the few programs that won't work without Windows. SecuritySpy has the option to FTP files on a schedule with a static filename (like "image.jpg") as well as streaming video. It appears to lack the ability to make time-lapse videos. https://www.bensoftware.com/securityspy/ (Not a recommendation since I haven't tried it yet.)
i am presently running SecuritySpy and it is the mac version of Blue Iris, with some notable differences. I have two foscams that have the ability to send images (FTP) directly to a server. The downside is the inability for them to overwrite the previous image , hence a lot of time stamped images that quickly fill up the capacity of the server to goes to. Sadly that was a function they had when they were in the infant stage. I really liked being able to shut my computer down or in to sleep mode and have the cameras send the images to WU, then I could embed the image onto my web page as it updated.
So I am using Security Spy. It is expensive to use. There are other programs but are questionable because of the permissions they require. WeatherDisplay, WeatherCat will send images to sites they can populate. I do have dual platform via parallels desktop that I could use.
What I need, unfortunately isn't something available the camera that doesn't send timestamped updates, but only the current image.
Weather Underground provided a lot, not only could you get the current conditions but you would see the cloud or surface condition . It provided a lacing of sorts between the two.
So WU right now accepts our data and that is fine, the images are gone for now. Shit. double shit
