Discussion on monitoring of centralized power supply
It's no problem for you to walk like that. 1.5 square power cord is enough. Pay attention to the interference between 220V and video line.
If each camera is only 60 meters away, if I were you, I would choose DC 12V transmission, because the distance is not far, and there are only four cameras, and the load is very small (except fastball or Yuntai). The advantage of this method is that 1 avoids the interference of 220V on video signals. Weak current transmission is safe and reliable, and easy to maintain. In this way, considering the pressure drop, it is enough to choose the power supply of 15V6A and the power supply line of 1.0.
Please adopt it.
