Hello, I have implemented 3cx as the PBX system in a local art gallery. We are looking at integrating the front door bell and camera into the PBX. Currently they have an ancient camera and screen in a central location and a hacked door opener from SIEDLE in three locations that activate the relay in the door opening it. I wish to have the similar functionalities in the new system. I want an IP camera (With POE) that sends a video feed to the 3cx client call group when one of the two doorbells (also from SIEDLE) are pressed. Then I want to be able to dial a number to activate the relay that opens the door. I have looked at all in one door phones but due to us having a glass front door I cant mount sucha device. I need to have the bell and the cameras in different positions. ideally I would like to use the door bells that already exist.
