Solar Powered Security Camera & Driveway Light

This solar powered security camera consists of a WiFi HD security camera with a DC-DC converter to ensure constant 12vdc, 110aH GEL battery, 80w SolarWorld solar panel, Morningstar Sunsaver MPPT charge controller, and LED motion sensing floodlight.

Then I mounted all the equipment. The solar panel is mounted with a generic mount I scored on eBay, some conduit for the wiring, and a group size 31 battery box from Amazon.
