Fingerprint Identification System

In the process of crime scene investigation, in order to find more biometric materials, potential fingerprints, tool traces and other traces, and obtain more investigation clues and criminal evidence, the investigators need to use a variety of technical means to conduct a detailed investigation of the crime scene. In the process of crime scene investigation, in order to find more biometric materials, potential fingerprints, tool traces and other traces, and obtain more investigation clues and criminal evidence, the investigators need to use a variety of technical means to conduct a detailed investigation of the crime scene. The scene investigators need to carry a variety of exploration equipment in the process of handling cases, such as: SLR camera, video recorder, infrared camera, ultraviolet camera, ultraviolet light source, multi-band light source and so on, and need to be frequently switched between a variety of equipment, cumbersome operation, low exploration efficiency.

GA300Full Wide Fingerprint Identification System is a portable field trace material evidence non-destructive search equipment, its spectral response range between 200nm and 1000nm, belonging to the ultra-wide spectral response. It has many common functions optical exploration instruments, and advantages of powerful function, light volume, simple operation and easy to carry. Its launch freed field investigators from tedious equipment switching, successfully reduced the burden on law enforcement personnel, and effectively improved the efficiency of case handling.

• Scientific pole SCMOS image sensor;
  
• Spectral range：200nm~1000nm;
• Resolution/Pixels: 2048X2048，4 million pixels;
• 7 inch IPS HD, 1280*800 pixels.;
• Heat dissipation method: Fan cooling
• Image processing: with the image processing button, can adjust the image contrast, adjust the exposure intensity, image zoom and other parameters;
• Data transfer: with wireless real-time transmission function;
• Macro shooting: imaging distance≥10cm
• Intelligent recognition: identify the fingerprint on the photo, do a certain enhancement algorithm;
• Full spectrum parallel light source;
• Extremely high sensitivity in the full UV region;
• For different objects (such as lime wall, glass door, paint door, thermal paper, etc.), the left fingerprint has a high sensitivity to search and identify the ability, has a powerful search and evidence collection function.
• Sharp spectral effect, trace searching and evidence collection of biometric materials can be completed in one step. For the traces covered by blood, it has a powerful function of searching and collecting evidence. Extremely high sensitivity in full ultraviolet region, sensitivity never attenuates.
• Large screen high-definition display, fingerprint, footprint, fine spots, sweat, occulting blood, seal text and other details magnify, continuous image RAW lossless compression format material evidence recording and ultra clear image output, suitable for criminal science crime scene investigation material evidence search recording system.
• Customized sensor, light source and filter system for high-definition material evidence shooting and ultra clear material evidence imaging in criminal science scene, with integrated human design, it is the most practical and practical recording imaging system for crime scene investigation and evidence collection.
• Focus multiplier noise reduction: using low illumination sensor on large target surface, noise separation through multi-point sampling noise reduction technology, can obtain continuous high-definition image trace.

Application

• Public security material evidence collection;
• The system of searching, recording and collecting occult blood traces of dark fabric
• Biometric trace acquisition and recording system.

Advantages

• Wide spectral trace search light source: Small size, portable design, directly installed in the front of the host lens, built-in double light source, direct blood spots, fingerprint trace light contact search.
• Portable directional reflection deshadow camera device: Portable light source integrated darkroom design, not by the interference of external light; Directly installed in the front of the main lens for trace identification. It is easy and quick to pick up fingerprint image on complex background interface. The power is 16W, the spectral range is 365nm, the light source life is ≥50000h, the form of light source: smooth surface light source. The light source Angle is 90°, and the mirror can be fine-tuned ±5 degrees for uneven interface to ensure the vertical orientation of the photographic axis and the trace interface.
• Biometric material trace fluorescence excitation optical device.
