Cable Standard:
Cable’s quality directly affect the video signal transmission quality. in order to achieve good quality signal transmission, recommend use standard cat 5e/6 or better utp cable.
Warm Tip:
The cable quality, could use “multimeter” check one pcs twist pair wire’s DC impedance. normally request dc impedance<18Ω/100m, that means < 54Ω/carton.
