The End of Life of the Flash Player is a problem for my security cameras. I have a NVR and also use Apple iMacs. Two of my cameras are wifi and use flash to broadcast to my NVR. The feeds died to my NVR with the blocking by Adobe. Individual feeds to my iMac are also blocked by Adobe. Apple generally is not supported by many surveillance manufacturers except through Flash. And these manufacturers will not provide work arounds for their products. Instead of a visual feed, now only a popup shows with a flash symbol. When clicked it takes you to an End of Life page that says that Adobe is protecting you. Protecting me! It's cut out secutity cameras that was protecting me and my property. If Adobe helps me any more I will be a dead man.
Your camera vendor has had three years to make an update available to remove the Flash dependency.
Here's the original announcement from 2017:
If an update is not available from the NVR manufacturer to remove the Flash dependency, then you'll need to buy an updated NVR that works with your cameras and doesn't require Flash.
