This paper proposes an automated, long-range selfie camera system using LORA (LORA-SELFIE). LORA-SELFIE addresses the FOV problem of smart phone cameras by enabling users to take selfies and landscape photos automatically from a distance. On LORA-SELFIE, a wireless sensor network is used to track users presence at designated shooting spots. If a user is not found at the designated spot, LORA-SELFIE goes to sleep mode to save energy. Moreover, the operating range of LORA-SELFIE can be extended easily by adding more relay nodes to the network. Experimental results show that LORA-SELFIE solves the FOV problem and is even better than an existing commercial system in terms of energy-consumption, and processing time.
