I. Requirements Analysis:

In emergency rescue scenarios such as earthquakes, geological disasters, or fires, swiftly and accurately locating trapped individuals is critical. Audio-visual life detectors, as rescue devices integrating multiple advanced technologies, can capture real-time audio-visual information from the scene. This enables rescue personnel to rapidly pinpoint trapped individuals, thereby enhancing search and rescue efficiency. Consequently, there is an urgent market demand for a comprehensive, stable-performing audio-visual life detector.

II. Product Features:

1. Infrared Thermal Imaging Function: Equipped with an infrared thermal imaging probe capable of penetrating smoke, dust, and other obstacles to detect heat sources from trapped individuals, providing robust support for search and rescue operations.

2. Recording and Voice Intercom: Equipped with recording functionality to capture on-site audio information, while supporting voice intercom to enable real-time communication between rescue personnel and trapped individuals, thereby enhancing search and rescue effectiveness.

3. Lighting Function: Equipped with a built-in high-brightness light, it provides ample illumination for rescue personnel in low-light or nighttime environments, ensuring the smooth progress of search and rescue operations.

4. Wireless Transmission: The command terminal communicates wirelessly with the audio-visual host unit, with a communication range of ≥100 meters. This ensures real-time transmission of audio-visual information, enabling rescue personnel to quickly grasp the situation on-site.

5. Extended Battery Life: Operating time ≥10 hours to meet the demands of prolonged search and rescue operations, reducing charging frequency and enhancing rescue efficiency.

III. Application Scenarios:

1. Earthquake Rescue: Following an earthquake, audio-visual life detection devices can be deployed to search for survivors within collapsed structures. Utilizing infrared thermal imaging and audio recording capabilities, these devices rapidly locate trapped individuals, thereby enhancing rescue success rates.

2. Geological Disaster Rescue: At sites of geological disasters such as mudslides and landslides, audio-visual life detectors can be used to search for and rescue individuals trapped beneath debris. These devices provide rescue personnel with real-time audio-visual information to assist in formulating rescue plans.

3. Fire Rescue: At fire scenes, audio-visual life detectors can penetrate smoke to locate trapped individuals. Simultaneously, they utilize voice intercom functionality to communicate with trapped persons, guiding them to self-rescue or await rescue.
