1. A system comprising:
a power-over-ethernet (POE) network switch that provides energy;
a controller that communicates with the POE network switch;
a rechargeable battery directly connected to the POE network switch, wherein the rechargeable battery is recharged with the energy directly from the POE network switch; and
a plurality of low duty cycle devices,
wherein, over a first interval, the plurality of low duty cycle devices draw a peak power during activating the low duty cycle devices,
wherein, over a second interval, the plurality of low duty cycle devices draw negligible power, compared with the peak power draw or no power draw,
wherein each of the plurality of low duty cycle devices are configured to be separately charged via the controller, and
wherein, based on if power of the rechargeable battery is sufficient to supply power simultaneously to multiple of the plurality of low duty cycle devices and power draw information about the plurality of low duty cycle devices, the controller determines (i) if the controller uses the energy directly from the rechargeable battery to the controller, then to each of the plurality of low duty cycle devices or (ii) if the controller switches to using the energy from the POE network switch to the controller, then to each of the plurality of low duty cycle devices.
