It is strictly prohibited for any unit or individual to use this equipment to implement illegal and criminal acts such as illegal surveillance, secret photography, eavesdropping, and infringement of citizens' personal privacy.
Product Overview
The Long-Distance Forensics Instrument (Dual-Channel Remote Observation and Recording System) is a professional medium and long-distance forensics and covert surveillance system integrating high-magnification optical observation, high-definition audio and video electronic recording, and encrypted wireless transmission. It is also the core special equipment for SWAT anti-terrorism and explosion-proof emergency disposal, criminal technical investigation and forensics, and major event security work. The core of this equipment adopts an integrated design of main/auxiliary dual optical channels, which is deeply customized for statutory tasks such as criminal investigation covert surveillance, VIP security, anti-terrorism emergency disposal, major event on-site monitoring, and border port remote inspection. It can realize high-definition detailed observation of medium and long-distance targets, accurate feature identification, whole-process continuous recording and real-time encrypted back transmission of audio and video information.
The equipment deeply integrates the excellent observation performance of traditional high-end optical instruments and the convenient operation capability of modern electronic forensics equipment. It can safely, efficiently and compliantly obtain complete audio-visual evidence materials without exposing the investigators or alarming the observed targets. Through the optional functional modules, it can realize real-time picture synchronization, information interaction and command scheduling between the rear command center and the front-end investigators. It is an important technical equipment to improve the long-distance intelligence acquisition capability, audio-visual evidence fixation efficiency, and multi-unit coordinated combat level of front-line units.
Technical Principle
The core of the system is built based on the collaboration of dual-channel high-precision optical imaging technology and digital audio and video electronic signal processing technology. The whole forensics operation complies with the relevant specifications for the collection of audio-visual evidence in criminal proceedings. The recorded audio and video materials have complete judicial evidence validity and can be directly used in case investigation and judicial litigation links.
The equipment is equipped with two sets of independent optical imaging systems, the main and auxiliary ones. The main optical channel is equipped with a 100mm large-aperture objective lens and a 25-100 times continuous high-magnification zoom eyepiece group, which has extremely strong light-gathering ability and detail resolution ability, and can realize high-definition detail magnification observation and feature identification of ultra-long-distance targets. The auxiliary optical channel is equipped with a 25mm objective lens and a 6-25 times continuous zoom eyepiece group, which provides an ultra-wide observation field of view, and can realize fast scanning of large-scale scenes, continuous tracking of moving targets and overall situation awareness. The two channels can be quickly and flexibly switched through the mechanical structure, taking into account the dual practical needs of large-scale search and refined detail identification.
The picture observed by the optical system completes photoelectric conversion through the built-in high-sensitivity photoelectric sensor, converts the optical signal into a high-definition digital electrical signal. After optimization and noise reduction by the built-in image processing unit of the system, it can be displayed on the 5-inch high-definition built-in display screen of the equipment in real time for the front-end operators to observe, focus and lock the target in real time. At the same time, the built-in coding processing unit of the system can perform real-time digital compression coding on the audio and video signals, and encrypt and store the dynamic video in MPEG-AVI format and static photos in JPG format in the external memory card. The integrated high-fidelity microphone and audio processing circuit can synchronously collect the full-range ambient sound of 20Hz-20KHz, realize synchronous digital recording of audio and video in the observation process, and complete the instant fixation and closed-loop retention of audio-visual evidence.
Through the optional 4G wireless image transmission module and GPS positioning module, the system can encrypt the front-end real-time audio and video stream and equipment location information with national secret level, and then transmit them to the rear command center or coordinated combat unit in real time, realizing remote real-time monitoring, visual command scheduling and full recording of investigation tracks, greatly expanding the operating radius of individual soldier investigation and the coordinated combat capability of multiple units.

Compliance Practical Application Cases
-
The Criminal Investigation Detachment of the Municipal Public Security Bureau investigated a series of cross-regional motor vehicle theft cases. Through preliminary investigation, it locked that the vehicle hiding dens of the criminal gang were located in an abandoned factory area in the suburban area. However, the surrounding area of the factory area has a wide view, and close-range investigation is easy to be exposed, which makes the investigation work difficult to advance and cannot fix the criminal evidence of the gang. After fulfilling the statutory approval procedures, the investigators carried this Long-Distance Forensics Instrument, completed the erection and deployment at a hidden commanding height 800 meters away from the factory area, and carried out 24-hour uninterrupted covert monitoring and forensics.
Through the wide-field auxiliary channel of the equipment, the investigators fully grasped the personnel activities and vehicle entry and exit rules in the factory area; through the 100 times high-magnification main channel, they clearly recorded the physical characteristics of the gang members, the license plate numbers of the involved vehicles, the complete criminal process of dismantling and modifying the vehicles, and synchronously recorded the dialogue content between the gang members, completely fixing the criminal evidence of the gang. According to the audio-visual evidence obtained by the equipment, the investigators accurately grasped the crime rules and personnel structure of the gang, launched a centralized network closing operation when the gang committed theft again, arrested all 8 involved personnel of the gang in one fell swoop, seized 17 stolen motor vehicles, and successfully detected the cross-regional series of theft cases. The complete audio-visual evidence recorded by the equipment was all accepted by the procuratorate as the core evidence for the prosecution of the case.

An international marathon event was held in China, with a total route of 42 kilometers, passing through the urban core area, suburban sections, and mountain sections along the line. The line is densely populated and has a complex environment, which makes the security work extremely difficult. The core requirement is zero potential safety hazards and zero sudden risks throughout the whole process. In this security work, the event security headquarters deployed this Long-Distance Forensics Instrument at 12 key commanding heights such as bridges, high-rise buildings, and mountains along the event route, building a visual monitoring network covering the whole event route.
During the event, the security personnel continuously monitored the crowd flow and track conditions along the event route through the wide-field auxiliary channel of the equipment, and fully grasped the overall situation of the site. For key parts such as densely populated areas, curves, and supply stations, they carried out detailed screening through the high-magnification main channel, quickly identified and checked many potential safety hazards such as personnel climbing over guardrails and irrelevant personnel breaking into the control area, and simultaneously completed evidence fixation and scheduling of on-site disposal forces. Throughout the event, the equipment operated stably and successfully completed the full visual monitoring and security guarantee tasks of the event. Its long-distance high-definition observation capability, portable deployment characteristics, and continuous and stable operation performance were highly recognized by the event security headquarters.
