Improving the Quality of Forensic Evidence

DCS™4

DCS4 - Fingerprint enhancement and examination

A dedicated workstation for the recording and enhancement of latent fingerprints
..............................................................................................................

Description

The DCS™4 is a dedicated workstation for processing latent fingerprints offering the complete solution to their examination from capture to enhancement to courtroom presentation as evidence.

Key to the effectiveness of the DCS™4 is the simple way in which enhancement software is made available to the operator, allowing complex operations to be applied in just a few clicks of the PC mouse.

DCS4 features include:

  • Image capture using a high resolution digital camera
  • Photo Wizards - guidance on photography of processed latent prints
  • Software toolboxes - a guide to effective image enhancement
  • Image validation - authentication of original image
  • Audit trail - logs details of image processing from capture to printout using simple language
