Сable type that is used for device connection depends on the distance between the last indoor monitor in
the system and outdoor panel:
а) Use 4-wire cable with such parameters:
• distance up to 25 meters (82 ft.) use a cable with 0,22 mm2 square of one wire (AWG 24);
• distance 25 to 50 (82-164 ft.) meters use a cable with 0,41 mm2 square of one wire (AWG 21);
• distance 50 to 100 meters (164-328 ft.) use a cable with 0,75 mm2 square of one wire (AWG 18).
b) If the distance between door monitor and door panel is between 80 and 100 meters (262-328 ft.) then
use a 3-wire cable with 0,75 mm2 (AWG 18) 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):
