Doorbell / camera view + unlock?

[zerqz]

Greetings!
Not sure if this was the right place to post this apologies if it is not;

I was wondering if anyone here had setup ZoneMinder with a usb relay so when someone presses a doorbell it brings up a certain camera view fullscreen, and have a display pop up saying "unlock door y/N" and if you press yes then it triggers a relay to unlock the door?

Not sure if this is possible with ZoneMinder, but I'm trying to find a opensource means prior to having to use something proprietary. I'm also looking into weather iSpyConnect can do this, but would also rather not use a windows based server.

If anyone has any ideas your help is greatly appreciated, thanks!

For features like this, youll need to be able to control output states s.a. a relay.

Standard computers are generally not equipped with the required circuits.

However this is very easy to execute on a Raspberry PI.
On the internet you will find lots of examples how this can be done!!
If you need some extra help, please let me know!

Kind regards. Christo
