Mine is Samsung Galaxy 5 (ya old school as hell) and Blnk XT. No indoor cams and no XT-2 cams. My stuff still works cause it doesn’t have all the bells and whistles. The new stuff is plagued with firmware and software/app updates. I also don’t have any smart home devices, no damn ding dong doorbell camera, no echo this or alexa that.
I learned a long time ago, never ever let the tail wag the dog. Keep it simple and it works. Well as good as Blink can work for an entry level home monitoring device. Don’t kid yourself, it is not a home security system.
