USR JIG02 as Edge Gateway for Solar Powered CCTV
Overview
The JIG02 acts as the heart of the system, combining connectivity, data acquisition, video integration, and remote management into a single rugged device.
Key capabilities include:
-
Reliable internet connectivity via LTE / 5G RedCap
-
Continuous data acquisition from the solar controller via RS485 (Modbus RTU)
-
Overlay of solar & battery data directly onto CCTV camera RTSP video streams
-
MQTT publishing of solar, battery, and GPS data to cloud dashboards
-
SMS notifications for critical events such as low battery or tampering
-
Built-in relays for automated load control and power conservation
System Architecture
The deployment consists of:
-
Solar Controller (energy source + battery management)
-
JIG02 Edge Device (connectivity + protocol conversion + intelligence)
-
CCTV Camera(s) for security and situational awareness
-
Cloud Dashboard for visualization (ThingsBoard, Grafana, Ubidots, etc.)
-
SMS Notification Layer for critical events
-
Relay Outputs for conditional power management
Connectivity is ensured via LTE / 5G RedCap, making it suitable for remote, off-grid installations.
How JIG02 Works
Solar Controller Integration
-
JIG02 leverages its DeviceSupervisor industrial protocol server to continuously poll solar and battery parameters via Modbus RTU over RS485.
-
Beyond monitoring, it enables remote configuration of charging profiles, load limits, and timer-based switching, giving full remote control of the solar controller.
CCTV Camera Integration
-
Provides stable internet access for camera streaming and remote management.
-
Supports public IP, DDNS, and port mapping for direct camera access.
-
Inserts real-time solar/battery status overlay into the RTSP video feed for combined energy + surveillance monitoring.
SMS Notifications
-
Critical alarms are sent via SMS for instant awareness.
-
Examples:
-
-
Low battery voltage
-
-
-
Tampering events (reed switch, external sensors, or camera outputs)
-
Dashboard Visualization
-
Historical and real-time data (solar, battery, load, GPS) are published using MQTT.
-
Compatible with mainstream IoT platforms:
-
-
ThingsBoard (open-source, customizable)
-
-
-
Grafana (advanced analytics and dashboards)
-
-
-
Ubidots (cloud-friendly, user-focused)
-
-
Enables intuitive trend graphs, geolocation maps, and system health monitoring.
Relay-Based Load Management
-
Built-in relays allow devices (e.g., loads, external systems) to be connected.
-
Conditional logic enables battery-level-based disconnection, extending system runtime and protecting the battery.
