Application Introduction of the All-Weather Remote HD Observation and Investigation Forensics System in Criminal Investigation and Judicial Forensics

Technical Principle

1. Principle of Ultra-Telephoto Optical Imaging and Fog Penetration

    

   The core optical component of the system adopts an 80mm large-aperture objective lens and a 600mm focal length high-magnification zoom lens group, matched with a 25-75 times continuous optical zoom structure, and combined with multi-layer special optical coating technology, which can greatly reduce the light refraction loss and improve the light transmittance. At the same time, it can effectively filter the scattering interference of light by suspended particles in fog, smoke and rain water. Combined with the built-in digital fog penetration enhancement algorithm, it realizes the dual fog penetration effect of optics + digital. It can penetrate harsh weather media such as haze, sand and light rain, and restore clear picture details of targets several kilometers away, solving the core pain point that traditional observation equipment has blurred imaging and unrecognizable targets in bad weather.
    
2. Principle of Low-Light Full-Color Night Vision Imaging

    

   The low-light night vision function of the system is realized based on a high-sensitivity large-target image sensor and 3D intelligent noise reduction algorithm. It can effectively collect and amplify the weak light signal in the environment under the extremely low illumination environment of 0.01Lux, and complete picture noise reduction, detail enhancement and color restoration through a professional image processing engine. It can still realize full-color HD imaging without infrared fill light in the near-black night environment, completely breaking through the technical limitation that traditional infrared night vision equipment can only output black and white pictures with lost color information and easy to expose the investigation position. It can completely retain key judicial evidence information such as the clothing color, facial features, vehicle license plate, and object identification of the target person. It also supports one-key switching between full-color/black and white modes to adapt to the observation needs of different night investigation scenarios.
    
3. Principle of HD Coding and Dual-Link Forensics Storage

    

   The system has a built-in independent high-performance computing and hard coding unit, which can perform full real-time and delay-free hard coding processing on 5 megapixel HD video stream without picture quality loss and frame loss, ensuring the integrity and continuity of the video picture. The host has a built-in dual-system encrypted storage architecture, with 32GB built-in storage space, and supports external memory card expansion up to 32GB, which can realize encrypted storage of the host locally. At the same time, it supports synchronous transmission of video streams to external terminals such as tablet computers and notebook computers through encrypted Wi-Fi or wired network, realizing synchronous recording and display of the terminal, forming a dual-backup forensics link of "host local + external terminal". The whole process adopts encrypted storage format, and the video files cannot be tampered with and can be traced throughout the process, fully complying with the statutory requirements of judicial audio-visual material evidence.

   For major cases and events such as homicide, major production safety accidents, and disaster accidents, the system can be used to complete high-definition panoramic picture and detail feature recording of the crime scene. The recorded video data can be used as judicial evidence of the original state of the crime scene and included in the case file for archiving. At the same time, the on-site picture can be transmitted to the rear expert consultation platform in real time through the network, realizing remote expert on-site review, case analysis and investigation guidance, providing technical support for the investigation of major and difficult cases, and also providing complete on-site image data for subsequent forensic identification and accident cause analysis.
    

Core Technical Parameters

Practical Application Cases

1. The Criminal Investigation Detachment of the Municipal Public Security Bureau investigated a cross-regional series of burglary cases. The criminal gang committed more than 30 crimes in a wandering manner, with a huge amount involved. They had a strong sense of anti-investigation, stepped on the spot many times before committing the crime, disguised themselves throughout the crime, and left very few clues at the scene. The investigation of the case fell into a deadlock. Through big data research and judgment, the investigators locked a temporary hiding den of the gang, which is located in an abandoned factory in the urban-rural fringe, with a wide surrounding vision and multiple lookout points. Close squatting is extremely easy to expose, and there is no lighting facility in the factory area, so night monitoring is extremely difficult.
    
   The investigators used this All-Weather Remote HD Observation and Investigation Forensics System, erected it in a concealed position of a residential building 2 kilometers away from the den, carried out all-weather monitoring of the den through 75 times optical zoom, and used the low-light full-color night vision function to clearly capture the facial features, entry and exit rules, and crime tools carried by the gang members in the dark night environment without light. At the same time, it completely recorded the whole process of the gang members discussing the crime plan and dividing the stolen goods after returning from stepping on the spot.
    
   Through the encrypted wireless transmission function of the system, the on-site picture was transmitted back to the rear command center in real time. The commander grasped the dynamics of the gang throughout the process, accurately formulated the arrest plan, and finally successfully arrested the gang when they were ready to commit the crime again. They wiped out the cross-regional burglary criminal gang, arrested 8 suspects, and solved 32 cases. The complete video data recorded by the system became the core legal evidence for the conviction and sentencing of the case, and was fully accepted by the People's Court in the criminal proceedings.
    
2. The Anti-Drug Corps of the Provincial Public Security Department, together with the border management department, investigated a major cross-border drug manufacturing and trafficking case. The criminal gang built a drug manufacturing den deep in the dense forest of the border mountainous area, with complex surrounding terrain and perennial fog, and set up multiple mobile lookout checkpoints. The entry and exit rules of personnel and vehicles are extremely strict. Close-range investigation is extremely easy to expose, and traditional monitoring equipment cannot achieve effective observation in the foggy environment of the mountainous area. The investigation of the case encountered a bottleneck.
    
   The anti-drug investigators used this system to erect it at a concealed position in the col 3.5 kilometers away from the drug manufacturing den. Using the optical + digital dual fog penetration technology of the system, they broke through the perennial fog environment restriction in the mountainous area, and clearly observed the personnel activities, raw material handling, and operation of drug manufacturing equipment in the den. Through the low-light full-color night vision function, in the dark night environment without light, they completely recorded the whole process of transportation and handover of finished drug products, and accurately locked the license plate of the involved vehicle, the physical features of the driver, and the drug handover route.
    
   Through the two-way intercom function of the system, the investigators linked with the rear command center in real time, updated the dynamics of the gang synchronously, and finally implemented accurate interception during the drug transportation, and simultaneously carried out the arrest of the drug manufacturing den. They arrested 17 suspects, seized more than 280 kilograms of finished methamphetamine and several tons of drug manufacturing raw materials, and successfully destroyed the cross-border drug manufacturing and trafficking den. The video data collected by the system completely restored the whole chain of criminal facts of the gang's drug manufacturing and trafficking, and became the key core evidence for case investigation and conviction sentencing.
