Maybe licensing rights and/or patents don’t allow it.
Maybe sales never suffered enough to justify it’s development
Maybe the new parent company Amazon NEVER had plans for it and still don’t.
And my #1 favorite…Blink is being kept dumb on purpose so it doesn’t infringe on Ring sales and other products Amazon markets.
Bottom line is, you’ll never know. There is as of today, only 146 threads in this subject. 146 is friggin tiny number compared to how many Blink cameras have been sold. What does that tell me? Not enough customer interest to spend the money to offer it. Lord knows existing Blink customers don’t want to pay any more money for additional features/benefits.
