Please note that additionally the opening of the door must be configured by DTMF code.

Door Intercom usage

The door intercom establishes a normal call when the bell is pressed, which can be received via SIP/SRTP from anywhere. The pascom client does not have to be in the same network.

Door opener usage

To open a door, the pascom client sends a DTMF code during the active call. The pascom client does not have to be in the same network and the door opener can be operated from anywhere.

Useful Information

  1. Why do Iphone devices have a black image when streaming video?
    If the door bell delivers the image/video data via HTTPS with a self-signed certificate, no image may be displayed on iOS devices. This is an iOS security policy. To get a picture, either a trusted certificate must be installed or the door bell must be switched to HTTP.
