When security cameras are deployed in outdoor environments, power supply for security cameras is not as easy as in indoor environments. The power supply in the indoor environment is relatively simple. If backup power is to be considered, a simple indoor UPS can be used. In the outdoor environment, a power supply box for security cameras with surge suppressor, UPS, battery, backhaul network and other functions is required. The outdoor environment also needs to consider temperature, rain and other factors. For scenarios without commercial power, the power supply for security cameras needs to consider the use of solar power, which poses a greater challenge to the whole system. This video will introduce you to some of our design experience in power supply box for security.
