The DIGITAL MATTER Remora3 4G (REMORA3-4G) is a battery-powered GPS asset tracking device designed for location-based monitoring of vehicles, machinery, containers, and other mobile assets. It features 4G-LTE-M/NB-IoT connectivity to transmit data over cellular networks and integrates a Bluetooth 5.2 gateway to communicate with Bluetooth-enabled sensors and devices. The device is designed for outdoor use and offers a battery life of up to 10 years, making it suitable for long-term monitoring tasks.

Applications
The Remora3 4G is suitable for monitoring mobile assets across various industries, including logistics, construction, agriculture, and public administration. It can be used, for example, to track construction machinery, transport containers, or vehicles to prevent theft, monitor usage, or capture real-time location data. The integrated tamper detection via magnetic tamper sensing enhances security by alerting to unauthorized access to the device.

Features and Specifications in Detail
The device supports multiple GNSS positioning systems, including GPS, GLONASS, Galileo, QZSS, and BeiDou, ensuring precise and reliable position tracking even in challenging environments. A 3-axis accelerometer detects movement and enables location functions upon motion, improving energy efficiency. The Bluetooth 5.2 gateway function allows communication with external sensors such as temperature or humidity sensors to capture additional data.

Technology Explained Simply
The 4G-LTE-M (Cat-M1) and NB-IoT technology enable reliable data transmission over cellular networks, with NB-IoT being particularly suitable for low data volumes and long-range coverage. The battery consists of two D-cells, each with a voltage of 3.6 V or 3.7 V, built into the device. The battery life of up to 10 years is achieved through energy-efficient components and intelligent operating modes. The IP67 protection rating means the device is dust-tight and temporarily waterproof, making it suitable for outdoor and humid environments. The operating temperature range is from −20 °C to +60 °C, ensuring functionality even in extreme climatic conditions.

Compatibility and Accessories
The device is equipped with a Bluetooth 5.2 gateway, enabling connection to compatible sensors. It can be combined with external sensors to capture additional data such as temperature, humidity, or vibrations. The input voltage of 5–16 V DC allows for external power supply if the battery is insufficient or continuous power is required. The enclosure is made of glass-fiber-reinforced nylon, providing high mechanical stability and resistance to environmental influences.

Mounting and Installation
The Remora3 4G can be mounted on various surfaces, such as vehicles, machinery, or containers. Mounting is typically done using fastening materials not included in the delivery. Installation does not require special workshop equipment, as the device is simply attached to the desired location and activated. The magnetic tamper detection ensures that any removal or manipulation of the device is detected and reported.

Operational Advantages
The combination of long battery life, robust construction, and integrated Bluetooth gateway makes the device a reliable solution for long-term asset tracking applications. Support for multiple GNSS systems increases the accuracy and reliability of positioning. Tamper detection and IP67 protection enhance security and outdoor usability. Energy efficiency and the ability to communicate with external sensors extend the device’s functionality for diverse application scenarios.
