• distance 25 to 50 meters use a cable with 0,41 mm2 square of one wire;
• distance 50 to 100 meters use a cable with 0,75 mm2 square of one wire.
b) If the distance between door monitor and door panel is between 80 and 100 meters then use a 3-wire
cable with 0,75 mm2 square of one wire and RG-59 or RG-6 coaxial cable for the video signal.
c) Shielded or non-shielded twisted pair (not recommended):
