The Geeni Camera runs on AC power and must be plugged into an electrical outlet. Without a source of power, the Geeni Camera will not work and will therefore fail to record any video/audio. You will not be able to use any features, and the camera will not be able to connect to the internet. As a result, it will be inaccessible through your mobile phone. To ensure continued video/audio footage capture, ensure that the power cord is intact and that the unit is plugged into a working electrical outlet.
