Yes the 8350 have a linkage relay.
What's your goal with it? Never used that, just throw away the connectors. Security systems are standalone ones, using a doorbell as alarm would never be my choice. I think the relay outputs are operated by the alarm inputs when the system is armed and sg occurs. Dry contacts, dunno NO or NC. Just take a voltmeter and chime them. Anyway, configure your Shelly to 12VDC operation and you must use a power supply. Connect the "+" to Shelly's "N" terminal and run the "-" through A01 to Shelly's "L". If A01/GND gives you NO you're good. When A01 is switched ON by your doorbell your Shelly will get the DC "-" and will trigger it's own relay. I think that is what you want to use. As in Shelly 1 the relay output is absolutely separated from the input voltage you can switch 230V with it. Don't try it with Shelly 2.5.
Why you don’t use 24/7 recording?
Nah , not needed , my other cameras do that based on motion and when not in "home mode"
For more security must have 24/7 recorting + motion detection ....Nah , not needed , my other cameras do that based on motion and when not in "home mode"
But using my google devices as intercom is more usefull
Nah, don't need it for security, just want a recording when a doorpress event happens, that works...
For what use?I dont undertend what you want ti do and what electrical door you mean.
Ah ok.Then you can just add enother button without use the display but ,which burglar take a time to do this.It is more easy to just to brake in the door.
