Impeccable 121,312 in March 1122

The video quality of the intercom camera is excellent. The sound is also very good. On the outside, there is the bell button that creates a ding-dong quite strong but not aggressive in the house. For interior console, some adjustments are possible on the image and sound. But I did not think it was necessary.
When ringing, pressing the bottom right button to establish communication with the camera.
You can see the night at 1 meter, the doorbell intercom lights blue night.
I did not test the automatic opening, because I can not connect to my door. By cons, in the future, this will go on an intercom gate, and I intend to use the digital memorization of opening.
