Power for cameras from a light switch

I needed a V2 to keep and eye on the file cabinets and there was not a convenient duplex receptacle close-by, and I didn’t want to run the power cord on the ceiling or across the hallway. On the other side of the wall was an attic space that had a switched light. I replaced the simple light switch with a combined switch/receptacle. Then a 5V power cord was routed from the new receptacle to a hole cut in the wall sheetrock very close the the camera. The hole was kept high to discourage mice from enlarging it for their use. Also the Micro USB needed trimming. The pictures provide more detail.
