Abstract
In this demo we present an energy efficient motion detection mechanism for a high-resolution wireless (battery powered) surveillance camera node. We use Raspberry Pi (RPi) as a camera sensor node to demonstrate two scenarios. In the first scenario, the RPi performs motion detection using Pyro-electric InfraRed (PIR) sensor, while in the latter we use an external low-power node to keep the RPi in low power mode and at the same time detect motion using PIR sensor. The main contributions of this demo are the power management implementation, a surveillance application and the evaluation of power consumption between the two scenarios.
