7. Installation
a) General information
The outdoor unit should be installed in the protected area, e.g. next to the front door (e.g. under an awning)
so that the visitor is standing right in front of it when he presses the doorbell button. The camera should be
installed approx. at a height of 150 cm, depending on the ambient conditions at the installation site.
The indoor unit is only suitable for installation in a dry, closed inner room, e.g. on the inside of the corridor.
The installation height should be approx. 140 cm.
Place a two-wire cable (not included) between the outdoor and the indoor unit.
The wider the distance between the outdoor and the indoor units, the larger the cable cross-
section has to be. Otherwise, the outdoor unit may not work.
Cable length up to 50 m: Cross-section 1 mm²
Cable length up to 100 m: Cross-section 1.5 mm²
If two indoor units are connected to each other, a cable with a cross-section of 1.5 mm² must be
used (cable length up to 20 m).
A door opener (e.g. for the front door) and a gate opener (e.g. for the entrance gate to the property) can be
connected to the outdoor unit directly.
Test the video door intercom system at the future installation site before drilling holes for fixed
mounting and placing cables. For this test, the same cable should be used at the corresponding
length that you will later use for connection of the outdoor and indoor units.
Install the outdoor and indoor units only on stable surfaces, but not on metal ones or near other
electrical/electronic devices.
Ensure that no cables or lines are damaged when drilling or screwing. The same applies when
placing connection cables and any masonry work required because of this.
Do not place the connection cable between the outdoor and indoor unit right next to other power
cables or lines; do not place it on or near metal faces. This may negatively affect transmission.
