Relationship between cable diameter (24V AC) and transmission distance 19
Relationship between Cable Diameter (24V AC) and Transmission Distance Appendix 3
The recommended transmission distances are for reference only, and the actual conditions
shall prevail.
For Cameras powered by alternating current, the maximum voltage lose rate allowed is 10%.
For example, when a device of 20 W rated power is installed 141 inches (42m) away from the
transformer, the minimum diameter needed is 0.8000 mm.
