9. Troubleshooting
No picture, no sound
• Check the voltage/power supply (plug-in mains adapter) and the correct wiring of the outdoor and indoor unit.
Door opener does not work
• Check the correct wiring of the door opener at the outdoor unit.
• The video-door intercom may control two door openers.
Note that the door opener connected to the screw terminals “D/O” is supplied with voltage/power directly (12 V, max.
1 A) if you push the button “ ” (3).
The screw terminals “GATE” in contrast are potential-free. Only an internal relay is switched here (for contact resili-
ence, see chapter “Technical data“). If a door opener is to be actuated at the screw terminals “GATE“, you need an
additional external voltage/power supply for the door opener.
When pushing the door opener, the display will go out for a few seconds.
• This is normal.
Flickering image on the indoor unit display
• This is caused, e.g. by counter-light or mirroring objects in the area of the outdoor unit‘s camera. Align the camera
in the outdoor unit differently if necessary.
Image too light or too dark, bad colours
• Adjust the brightness, contrast and colours in the setting menu of the indoor unit, see chapter 8. f).
