Solar-powered security cameras rely on small solar The first question many first-time camera buyers ask is how do solar security cameras work? In fact, solar-powered security cameras rely on small solar panels to convert sunlight into electricity, which then charges the rechargeable battery built into the camera. Integrated inverters in security cameras can also convert direct current (DC) power from the solar panels to alternating current (AC) power to provide power when the sun is out. Storing power from the built-in battery during the day keeps the solar-powered security camera working at night.
