Can You Keep the New SS Outdoor Security Camera Re-Charged with a POE to USB 5V Adapter?

I don't have a SS system as of yet. One obstacle for me to select SS is that I don't want to deal with recharging cameras. Our new house will be getting some POE (Power Over Ethernet) ports installed on the outside eaves/soffits for future camera locations. From there I can install an injector if one isn't provided.

I've found some adapters that can convert 48V POE to also provide a 5V USB port at the wall plate to be a power source for charging phones, tablets, etc. 

Is there any reason I couldn't use one of these adapters to power/recharge a SS outdoor camera (via a USB to USB-C adapter) to draw power and keep it recharged?

Thanks,
