A power conversion circuit for an internet protocol camera includes a voltage conversion circuit and a divider circuit electrically connected to the voltage conversion circuit. The voltage conversion circuit includes a linear voltage regulator for providing an operating voltage. The linear voltage regulator includes an input port, an output port and a feedback port. The divider circuit includes a first divider resistance and a second divider resistance. The output pot, the first divider resistance and the second divider resistance are electrically connected in series, the feedback port is electrically connected between the first divider resistance and the second divider resistance to obtain a feedback voltage. The input port is electrically a system power, and the output port outputs and provides an output voltage adjusted by the feedback voltage. |
