Product Overview

The Day/Night Long-Range Laser Night Vision System — 915nm Red-Glow-Free Active Laser Illumination, 36x Optical Zoom, 5.8GHz Wireless Video Transmission & Remote Control, Motion Detection All-Weather Remote Covert Surveillance & Evidence Collection System (also referred to as the Day/Night Long-Range Laser Night Vision Device or Remote Surveillance & Evidence Collection System) is a professional-grade remote covert surveillance and evidence collection device integrating active laser illumination, high-definition optical zoom, wireless remote control and video transmission, and motion-detection video recording. It constitutes a core all-weather remote surveillance and covert evidence collection platform in the fields of criminal technical investigation, special police tactical operations, and VIP protection. This product is deeply customized for the covert, sustained, high-definition observation and evidentiary preservation of targets at long range under low-light or zero-light conditions during criminal investigation and counter-terrorism emergency response missions. It perfectly adapts to high-risk covert investigation scenarios such as nighttime drug transaction surveillance, peripheral stakeout of smuggling rings, special police counter-terrorism tactical reconnaissance, long-range guidance during field manhunts, and perimeter surveillance of sensitive sites. Through a "person-machine separation" wireless remote control operation mode, the system transforms risky forward close-in observation into remote surveillance from a safe standoff distance. Combined with a 915nm red-glow-free semiconductor laser, it achieves an effective observation range of 400 meters at night. This fundamentally resolves the operational pain points of traditional night vision devices, such as the exposure risk caused by red glow, the inability to operate remotely, and the lack of integrated video evidence preservation. It provides investigators with "all-weather, non-contact, unattended, complete-chain-of-evidence" remote covert surveillance and intelligence gathering capability, serving as critical criminal technical investigation and evidence collection equipment that integrates modern technology-driven investigation with counter-terrorism tactics.

Technical Principle

This system is architected on the integrated technology of active infrared laser illumination and high-sensitivity low-light imaging, combined with wireless radio frequency remote control and video transmission mechanisms. Its night vision core consists of a 915nm red-glow-free semiconductor laser and a high-sensitivity CCD/CMOS image sensor. The laser emits a near-infrared beam at a wavelength of 915nm, which falls within the non-visual response range of the human eye and is far beyond the red-glow sensitive band of typical night vision detectors. Therefore, the illumination spot is completely invisible during nighttime operation, providing an exceptionally high degree of covertness. After the laser illuminates the target, the reflected weak near-infrared light, along with natural ambient light, is collected by a 36x optical zoom lens and projected onto the sensor. The sensor can still generate a clear black-and-white image at illumination levels as low as 0.1 Lux, with automatic day/night mode switching. Optical zoom and digital processing work synergistically, enabling smooth transitions between wide-area search and close-up identification.

Remote control and image transmission are based on a 5.8GHz wireless video transmission module. The device's main unit wirelessly transmits the real-time video signal to a detachable 5-inch wireless monitor, with a transmission distance of no less than 50 meters in an open environment. Through the monitor, the investigator can not only view the video in real time but also synchronously and remotely control the main unit's zoom, focus, pan-tilt 360° rotation and tilt, and laser on/off via a wireless remote controller, achieving fully-featured "unattended" surveillance. The main unit has a built-in motion detection algorithm; when object movement is detected within the frame, it can automatically trigger video recording, which supports loop recording onto built-in storage. The entire system is powered by a replaceable high-capacity lithium battery, supporting continuous operation for no less than 8.5 hours with the laser on. An external power supply can enable 24-hour uninterrupted operation. An independent OLED screen monitors the power status in real time, ensuring support for long-duration stakeout and fixed-point surveillance missions.

Core Functions and Compliance Operational Value

All-Weather Long-Range Covert Surveillance Capability, Providing Active Visual Intelligence Without Exposure Risk for Nighttime and Low-Light Environments
The device employs 915nm red-glow-free laser active illumination, with an effective nighttime observation range of 400 meters. Combined with 36x optical zoom, the daytime observation range can be extended to 800 to 1000 meters. The laser wavelength is completely invisible to the human eye, eliminating the risk of exposing the surveillance position caused by the red glow of traditional infrared night vision devices, allowing nighttime surveillance operations to continue completely undetected by the target. This all-weather long-range imaging capability ensures that in nighttime crime scenarios with extremely short time windows and exceptionally high risks—such as drug transactions and smuggling deliveries—investigators can clearly identify target vehicle license plates, individual characteristics, and behavioral processes from a safe distance. The continuous video data obtained can be directly used as audio-visual evidence in criminal proceedings, meeting the requirements of the Criminal Procedure Law that the sources of technical investigation evidence must be lawful and the content objective.

Person-Machine Separation Wireless Remote Control and Surveillance Architecture, Achieving "Unattended" Safe-Distance Remote Surveillance
The device supports the complete physical separation of the main unit and the 5-inch wireless monitor, with a transmission distance of no less than 50 meters in open areas. The investigator can covertly deploy the main unit at a forward position and retreat to a vehicle or shelter at a safe distance, viewing high-definition video in real time through the wireless monitor, and using the remote controller to remotely operate the lens zoom, fine focus adjustment, pan-tilt 360° rotation, and laser on/off. This person-machine separation mode fundamentally changes the hazardous operational method of traditional surveillance that requires investigators to set up equipment near the target and remain on-site. In high-risk missions such as peripheral surveillance of clandestine drug laboratories or cross-provincial smuggling vehicle tracking, it maximally ensures the concealment and personal safety of investigators while achieving continuous, uninterrupted omni-directional coverage of the target area. The investigative activity itself fully complies with the management requirements for the covertness and safety of surveillance methods in the approval and execution procedures for technical investigation.

Intelligent Motion Detection and Long-Duration Loop Recording, Constructing a Complete Chain of Unattended Evidence Collection and Preservation
The built-in motion detection algorithm automatically triggers video recording when object movement is detected within the surveillance frame, without manual intervention. The recording supports a loop recording mode, automatically overwriting the oldest files when the storage space is full, ensuring that space is continuously available to record the latest activity. With the laser illumination turned on, the main unit's built-in replaceable high-capacity lithium battery can operate continuously for no less than 8.5 hours, sufficient to cover a complete nighttime surveillance window. For long-duration stakeout at fixed positions, an external power supply can achieve 24-hour uninterrupted operation. This combination of "fully automatic triggered recording and long-endurance dual-mode power supply" completely eliminates evidence gaps caused by investigator shift changes, battery replacements, or manual start/stop of recording during unattended stakeout environments or multi-day continuous surveillance of major case perimeters. It provides a complete, continuous, unedited original audio-visual evidence chain for subsequent court cross-examination, establishing the objective foundation for electronic evidence to determine the case.

Professional Power Management, Portable Structure, and High Environmental Adaptability, Meeting Routine Tactical Deployment Needs Across Regions and Climatic Conditions
The main unit is equipped with a 1.8-inch OLED independent power management screen that displays the operating voltage, current, remaining battery level, and charging status in real time, allowing the operator to intuitively assess the battery margin before a mission and detect power supply anomalies during the mission. The total unit weight is no more than 1.8 kg, with a compact form factor, facilitating individual officer carry or covert deployment. The system design incorporates both lightning protection and anti-crash performance, adapting to extreme climates such as lightning-prone field areas, severe cold, and intense heat. This effectively reduces the risk of critical surveillance node loss due to equipment failure, providing a solid guarantee from the equipment reliability level for the normalized and efficient operation of criminal technical investigation and special police counter-terrorism duties.

Compliant Application Scenarios

Covert Surveillance and Remote Evidence Collection Scenario for Nighttime Drug Transactions, Smuggling, and Other Criminal Activities
During the investigation of organized crime cases such as drug trafficking and smuggling, investigators covertly deploy this night vision device several hundred meters from the transaction site periphery. Utilizing the red-glow-free laser active illumination and high-definition zoom, they clearly capture continuous video of drug deliveries, cash handovers, and the characteristics of individuals and vehicles in total darkness at night. The main unit and monitor are separated, allowing investigators to retreat to a secure location and adjust the viewing angle and focal length as needed via wireless remote control, completely recording the entire transaction process. The obtained video evidence, after lawful extraction and preservation, can be directly used as evidence in court. The investigative actions strictly comply with the legal authorization and approval procedures for technical investigation measures.

Long-Range Situational Awareness Scenario for VIP Protection and Counter-Terrorism Tactical Reconnaissance
During VIP protection duties for major international conferences, leader visits, etc., security forces deploy this device at elevated perimeter positions or key road junctions to conduct long-range covert surveillance of suspicious individuals and vehicles and transmit real-time images back to the command vehicle. In counter-terrorism emergency response operations, the special police reconnaissance team utilizes its 360° pan-tilt remote control function to perform dead-angle-free remote observation of the rooftops and windows of buildings where terrorists are hiding, providing precise forward intelligence for assault plan formulation. The entire process generates no visible light or audible exposure, ensuring tactical surprise.

Long-Range Guidance Scenario for Field Manhunts and Fugitive Tracking
When searching for fugitives in complex terrain such as mountains or dense forests, investigators use the night vision device to conduct long-range scanning of suspicious areas at night, promptly discovering and locking onto the fugitive's hiding location, number of individuals, and movement paths. The video is transmitted back to provide real-time guidance to the search team. Its person-machine separation mode allows investigators to remain safely concealed hundreds of meters away, avoiding direct confrontation and ensuring absolute superiority and safety during pursuit and encirclement.

Long-Duration Covert Perimeter Surveillance and Intelligence Gathering Scenario for Key Areas
For locations suspected of being used for drug manufacturing or illegal business operations, investigative agencies can set up this device at a fixed peripheral position and use an external power supply to achieve 24-hour uninterrupted surveillance. Motion-detection-triggered automatic recording, combined with loop storage, continuously documents the patterns of entry and exit of individuals, vehicles, and movement of goods. This provides a vast amount of foundational intelligence data for subsequent decisions on arrest timing, inference of the internal structure of the hideout, and analysis of accomplice relationships. The entire process is unattended and carries no risk of exposure.

Core Technical Parameters

Regarding the optical and imaging system, this night vision device is configured with a 36x optical zoom lens, enabling smooth switching between wide-angle search and telephoto identification. The minimum illumination is as low as 0.1 Lux, with automatic day/night mode switching to ensure continuous all-weather operation. The laser illumination system employs a 915nm red-glow-free semiconductor laser, with an effective nighttime observation range of no less than 400 meters (target detection), and a daytime observation range of up to 800 to 1000 meters. The wireless and control system features 5.8GHz wireless video transmission, paired with a 5-inch detachable wireless monitor, with a transmission distance of no less than 50 meters in open areas. It supports remote control functions including remote zoom, focus, pan-tilt 360° horizontal rotation, and tilt. The intelligent and storage functions include built-in motion-detection auto-triggered recording and loop recording. The power system utilizes a replaceable high-capacity lithium battery, providing a battery life of no less than 8.5 hours with the laser on. An external power supply can support 24-hour continuous operation. A 1.8-inch OLED power management screen displays voltage, current, and remaining battery level in real time. For physical characteristics, the main unit dimensions are approximately 164 × 194 × 97 mm, and the total unit weight is no more than 1.8 kg (including battery), with a lightning-proof and anti-crash design.

Compliant Field Application Cases

After a prolonged investigation into a cross-provincial drug trafficking network, a municipal anti-drug detachment obtained intelligence that the syndicate was about to conduct a large drug transaction in a derelict industrial park, with the transaction time set for 2:00 AM. Since the scene was an open area without any public lighting, investigators covertly deployed this laser night vision device in an unfinished building approximately three hundred meters from the central transaction point. After activating the 915nm laser active illumination, they clearly locked onto the vehicles and individuals in the central area using the 36x zoom lens. Two investigators retreated to a vehicle with the wireless monitor, adjusting the viewing angle in real time via the remote controller according to the on-site dynamics. Around 2:30 AM, the suspects began carrying woven bags to the buyer's vehicle. The motion detection automatically triggered recording, continuously capturing the entire transaction process and the facial features of several suspects without interruption. After the arrest order was given, the peripheral police force rapidly closed in, and none of the suspects escaped. Following the operation, the anti-drug detachment lawfully extracted and transferred the complete video stored in the night vision device, sealing it as evidence. This video evidence became the core objective evidence for the court to convict each defendant of drug trafficking.

While searching for a fugitive suspected of armed robbery, a public security organ assessed that he might be hiding in an abandoned residential house within a stretch of rolling hills on the city outskirts. After the search team arrived at the periphery at night, they used this night vision device to continuously scan the suspicious house and its surroundings with laser illumination from approximately two hundred meters away. They discovered intermittent flashlight movement inside the house and captured two blurry figures. The investigators transmitted the images back to the command vehicle via 5.8GHz wireless transmission, and the command center determined that there was indeed human activity inside. To prevent the suspect from escaping under cover of darkness, the search team decided to temporarily surround the area without moving, using the night vision device for continuous surveillance until dawn, while simultaneously fully charging all spare batteries for uninterrupted monitoring. Around 5:00 AM, a suspect climbed out of a back window. This movement was automatically recorded by motion detection and transmitted in real time to the monitors of the officers on perimeter duty. The suspect was apprehended immediately, and the other accomplice inside the house was subsequently subdued. In this case, the uninterrupted remote surveillance information provided by the laser night vision device laid a solid foundation for the scientific adjustment of the search plan and a casualty-free operation.
