I would really like the ability to trigger lights and sirens on multiple devices when viewing a doorbell. I have floodlight cams on side and rear of property, but we’re I to get an alert to an intruder or suspicious person on my doorbell cam, I would have to stop recording them and switch to each of the other devices to activate their sirens and lights.
Also, I would suggest the ability to leave a live view but with recording continuing for a short time after. On a single device, I may want to call the police, but continue to record evidence, and I don’t think that would be possible currently.
