A solar-powered wireless surveillance camera works by utilizing solar panels to convert sunlight into electricity, which is then stored in a rechargeable battery. This battery powers the camera and ensures continuous operation even during periods of low sunlight. The camera is connected wirelessly to a monitoring system, allowing real-time footage to be accessed remotely. Motion sensors trigger the camera to start recording when movement is detected, and the footage is typically stored on a cloud-based server for easy access and viewing. Overall, the solar-powered wireless surveillance camera offers a reliable and environmentally-friendly solution for monitoring and security purposes.
