Application Introduction of WPE-8000 Wireless Signal Passive Positioning and Detection System in Criminal Investigation Technology and Forensic Identification
The WPE-8000 Wireless Signal Passive Positioning and Detection System (Electronic Device Spatial Trajectory Analyzer) is a specialized wireless environment forensics and electronic device positioning equipment in the fields of criminal investigation technology and forensic identification. Based on the passive detection and analysis technology of the IEEE 802.11 series protocols (i.e., Wi-Fi), it can accurately detect, identify and track various Wi-Fi terminals without connecting to the target device or interfering with its normal communication. It provides non-intrusive and traceable technical support for criminal investigation forensics and forensic identification, solving the pain points of difficult tracking of hidden electronic devices, difficult restoration of on-site electronic environments, and difficult fixation of electronic evidence.
The core advantages of the equipment are accurately adapted to the needs of criminal investigation and forensic identification, helping to improve the quality and efficiency of identification work: full-band passive detection covers 2.4GHz and 5GHz, which can capture signals of various Wi-Fi devices and help discover hidden monitoring and wiretapping devices on site; the sub-meter level high-precision positioning capability, combined with multi-point deployment and professional algorithms, can accurately lock the spatial position of the device; the trajectory backtracking and data analysis functions completely record the historical signal data of the device, providing quantitative basis such as time, position and MAC address for identification; intelligent early warning and countermeasure can prevent information leakage in sensitive identification scenarios and ensure the compliance of evidence collection.
Combined with criminal investigation practice and forensic identification cases, its application value is prominent: Case 1, in a burglary case, investigators deployed the system around the crime scene, passively detected the Wi-Fi signal of the suspect's mobile phone, restored his activity route and stay time before and after the crime through trajectory backtracking. The recorded MAC address and position data provided key electronic evidence for confirming the suspect's presence and identifying the criminal trajectory in forensic identification. Case 2, in the identification of an illegal monitoring case, the system accurately detected the hidden wireless cameras on site by analyzing spatial Wi-Fi signals, extracted their MAC addresses, deployment positions and signal transmission records, assisted forensic identification in defining the scope of illegal monitoring, and provided strong technical support for case characterization.
In summary, the equipment is widely used in scenarios such as suspect positioning, criminal scene electronic environment investigation, and electronic data forensics assistance. It can realize the investigation of hidden electronic devices, device trajectory backtracking, and electronic evidence fixation, standardize the processes of criminal investigation forensics and forensic identification, improve the scientificity and rigor of identification conclusions, and provide reliable technical guarantee for electronic data forensic identification. It is an indispensable professional wireless forensics equipment in the fields of criminal investigation technology and forensic identification.
