The receiver module is a critical part of the wireless surveillance camera control system, designed for long-range, reliable operation using the LoRa Ebyte E22-400T22S at 433 MHz. Just like the transmitter, it leverages LoRa’s robust communication capabilities to ensure seamless data reception even in challenging outdoor environments.

Upon receiving control commands from the transmitter, the receiver processes the data via an ESP32-S3 microcontroller and executes precise motor movements for the surveillance camera tilt function. This ensures accurate positioning based on the preset values sent from the mobile application through the wireless network.

A key feature of the receiver design is the integration of four high-quality Omron relays, providing versatile control options for additional devices such as lighting, auxiliary motors, or alarm systems. The relays offer exceptional durability, ensuring stable performance in both indoor and outdoor installations.

The entire receiver unit is built on a custom PCB, optimized for reliability, compactness, and easy integration into existing camera stations. This PCB design was shared on PCBWay, making it accessible for replication and community-driven enhancements.

This receiver module delivers a robust, maintenance-friendly, and scalable solution, enabling long-distance camera control without the limitations of wired connections.
