Transmission distance vs. Cable impedance & Cable attenuation
The formula below shows interactive factors between current and transmission distance. You are able to
calculate the power transmission distance when it is applied to the physical installation site.
I xΩ
Ω Ω Ωx L < 40 (For AC power Speed Dome); i.e. The value of I xΩ Ω Ω Ωx L must be less than 40.
I xΩ
Ω Ω Ωx L < 80 (For DC power Speed Dome); i.e. The value of I xΩ Ω Ω Ωx L must be less than 80.
I= Ampere (Speed dome requests current)
Ω Ω Ω Ω=Ohm per meter (Maximum DC loop resistance of coaxial cable )
L= Power transmission distance
The formula below shows video transmission distance. You are able to calculate the video transmission
distance when it is applied to the physical installation site.
A x L < 30; i.e. the value of A x L must be less than 30.
A = Attenuation per meter of coaxial cable @ 60M Hz frequency.
L= Video transmission distance
