Relationship between cable diameter (36V DC) and transmission distance 20
Cable Diameter (36V DC) and Transmission Distance Relationship
Appendix 4
The recommended transmission distances are for reference only, and the actual conditions
shall prevail.
For Cameras powered by direct current, the maximum voltage lose rate allowed is 10%. The
cables mentioned in the following table are all copper cables with electrical resistivity
of
ρ = 0.0175Ω ∗ mm
