Multifunctional Night Vision Device

1.It features infrared, low - light, and fusion modes; is equipped with an eye - safe laser rangefinder, high - precision self - positioning, and target direction - finding and positioning functions; has the capabilities of memory card recording, rapid data destruction, and data export; and offers the option to be equipped with WiFi, Bluetooth, or 4G/5G communication modules, as well as voice recognition for auxiliary operation.

2.Positioning accuracy: The positioning module is used to accurately measure the geographical location of the device itself. The self - positioning error is no more than 10 m (CEP); the angular error in measuring the target azimuth should be no more than 0.5° (RMS), and the positioning accuracy for a target at a distance of 5 kilometers should be no more than 50 m (CEP). The positioning information uses the CGCS2000 coordinate system and can be displayed in both latitude - longitude coordinates and rectangular coordinates.

3.Imaging field of view: The maximum field of view angle is not less than 6.1×4.8°. The infrared channel is equipped with an electronic zoom function, and the low - light channel has an optical zoom function to enhance the reconnaissance and observation effects.

4.Recording and Storage Capacity:Information such as target azimuth, date, and time can be superimposed on pictures and videos for display. The storage capacity should be no less than 128GB. The memory device can be easily plugged and unplugged for replacement, and the stored content can be conveniently exported (the video frame size should not be lower than the resolution of the built - in display screen, and the frame rate should not be lower than 24 ± 1 Hz).

5.Portability:It should enable a single person to operate the portable device while holding it. The weight should not exceed 2.5 kg (including the main unit and working battery), and the total carrying weight of the whole device and necessary spare accessories should not exceed 3.5 kg.

1.Detection distance and accuracy    

（1）Recognition distance: Under good meteorological conditions (temperature not exceeding 20°C, relative humidity not exceeding 80%, visibility not less than 8 km, and illumination ranging from 10⁵ to 1×10⁻³ lux) and with unobstructed visibility, the effective recognition distance for identifying vehicles should be no less than 5 km (before image fusion).

  (2)Laser ranging range and accuracy: The ranging range is from 20 m to 5 km (under good meteorological conditions), with an error of no more than 5 m and a repetition frequency of no less than 1 Hz.

2.Visual enhancement ability 

   (1)It can perform fusion processing on the infrared and low - light band images of the target. After image fusion, it has an obvious visual enhancement effect

  (2)Under the condition that the visibility is no more than 5 km, the fog - penetration ability should be no less than 1.5 times the visibility

  (3)It has image processing functions such as image contrast adjustment and electronic zoom. The electronic zoom range is not less than 1.0 - 4.0×

3.Startup and continuous working time: The continuous working time shall be no less than 6 hours (at a normal temperature of 20°C)

4.Interface capabilities: It is equipped with a standard USB interface (USB3.0 standard, Type - C electrical interface), an RS232 data interface, a standard PAL - format video output interface, and an external charging interface

5.Operating temperature: -40°C to +50°C.
