We present a low-cost, low-power, long-range image sensor built from off-the-shelves components and enabling fully autonomous and out-of-the-box remote visual surveillance applications. The image sensor implements a packet loss-tolerant image compression technique that can run on very limited memory platforms. Long-range support is provided with Semtech LoRa technology. We detail the performance and energy consumption of the image sensor and describe how the system can be deployed in real-world scenarios using battery-operated image nodes.
