Standalone Audio-Video Recorder DSJ-HLN02A1: Professional Recording, Reliable Companion

In various professional fields of modern society, ranging from law enforcement duties to engineering operations, and from security patrols to emergency response, the need for authentic, clear, and stable audio-video recording of on-site situations has become crucial for effective workflow. Such recordings serve not only as objective documentation of work processes but also as key evidence for subsequent review, accountability determination, and outcome summarization. The HuoPro Standalone Audio-Video Recorder DSJ-HLN02A1 (hereinafter referred to as "DSJ-HLN02A1") is designed precisely to meet this market demand. With its compliant design, practical functionality, and stable performance, it provides users across various industries with a professional on-site recording solution, becoming a reliable partner for frontline workers.

The DSJ-HLN02A1 recorder features a compact body design with dimensions of 75mm × 55mm × 37mm (bare unit) and a lightweight bare unit weight of only 120 grams, with a total weight of 139 grams including the clip. Its small and lightweight form factor significantly reduces the burden on the wearer, allowing easy attachment to shoulders, chest, or pockets for unobtrusive, long-term use without discomfort.

The product casing is made of high-strength engineering materials, processed with precision craftsmanship, offering excellent protective capabilities. It boasts an IP68 protection rating, effectively preventing dust ingress and withstanding submersion in water for a certain period, making it resilient against rain, snow, dust, and other harsh weather conditions. Furthermore, the recorder has passed a 2-meter drop test, ensuring device integrity and functional reliability in case of accidental falls, demonstrating outstanding environmental adaptability.

The device is equipped with a 2-inch LCD high-definition display, delivering clear and detailed visuals. Users can perform operations such as live framing, playback review, and menu settings directly on the device without connecting to external equipment, offering intuitive convenience. The screen maintains good visibility even under strong sunlight, ensuring ease of use outdoors.

The DSJ-HLN02A1 runs on a stable Linux operating system, deeply optimized for smooth and responsive performance. It is powered by the reliable Guoke Wei 7202 / Novatek 675 chipset, providing a solid hardware foundation for high-definition video encoding/decoding, multitasking, and data encryption, ensuring long-term operational stability.

The device's battery life is particularly impressive. It houses a built-in 3500mAh high-capacity battery, enabling up to 19 hours of continuous recording and 23 hours of standby time. This means that even during all-day missions, frequent charging is unnecessary, greatly ensuring work continuity. For charging, it supports fast charging via a Type-C interface dock, reaching a full charge within 3 hours (using TYPE-C dock charger). The charging process includes clear status indicators, allowing users to monitor progress easily.

Imaging is the core function of the recorder. The DSJ-HLN02A1 is equipped with a 2-megapixel physical pixel starlight-grade camera featuring a 120° wide-angle lens. The high-pixel sensor combined with the wide-angle lens captures a broader field of view within a limited perspective, reducing distortion and ensuring recorded on-site footage is richer in content and clearer in detail. It delivers professional-grade image quality in both daylight and low-light conditions.

For video recording, the device supports multiple resolution options, including 2K, 1080P, and 720P, allowing users to choose flexibly based on storage space and quality needs. Videos are encapsulated in the mainstream MP4 format and support H.264/H.265 video encoding, effectively compressing file sizes while maintaining high quality, saving storage space.

The photo capture function is equally robust, offering various resolutions from 40323024 to 640480 to meet different scenario requirements. Images are saved in the standard JPEG format, ensuring strong compatibility for viewing and transfer across various devices.

Beyond basic recording, the DSJ-HLN02A1 integrates multiple intelligent features that enhance practicality and security:
