Remote Interrogation of Popular Blockers

Remote interrogation is a modern technique that leverages network video technology to conduct interrogations without the need for physical presence between investigators and suspects. This process involves the use of voice and video transmission channels, allowing real-time communication across different locations. Once the interrogation concludes, the transcripts are sent to the suspect's local procuratorate via the procuratorial network. These documents are then printed, verified, and signed by the suspect, while audio and video recordings are also generated and stored at the local prosecutor’s office. Compared to traditional interrogation methods, remote interrogation offers significant advantages. It eliminates the need for direct contact, making it more convenient for both investigators and suspects. Additionally, it enhances efficiency, reduces costs, and optimizes the use of judicial resources, aligning with principles of cost-effectiveness and streamlined procedures. The concept of long-distance trials has been gaining traction in recent years. Among the three key sectors under the public security law—courts, procuratorates, and public security agencies—the development of digital courts has been rapid, while digital interrogation systems have developed more slowly. Since 2013, courts have shown increasing demand for remote trial capabilities. In response, public security and procuratorate departments have begun planning remote trial systems alongside their existing court-based remote review systems. There are two main types of applications related to remote interrogation: localized synchronized audio-visual solutions and fully remote interrogation systems. Localized solutions include fixed-site and portable recording systems, while remote systems support features like telephony, multi-party conferences, and remote questioning. Public security interrogation services are divided into two categories: case handling centers (including police stations) and detention center interrogation rooms. The remote interrogation command system used by the procuratorate differs from standard remote interrogation systems, requiring real-time video and audio transmission and secure communication between the front-end and the command center. Courts have adopted the term "digital trial" to describe this new approach, and many courts now use remote interrogation systems to question suspects. The Supreme People's Court launched a formal remote interrogation initiative in 2009, aiming to establish a standardized model for remote interrogations and ensure quality and safety. Currently, remote interrogation systems are entering the high-definition era. However, challenges remain, particularly in terms of bandwidth limitations, which can lead to video distortion, data loss, and delays. These issues restrict the number of HD video channels that can be supported, especially in less developed regions where only basic systems are implemented. Network security is a critical concern. Remote interrogation signals are transmitted through secure judicial networks, and access is restricted to IP ports provided by the judicial department. This ensures that recorded files cannot be tampered with during transmission. Encryption, virtual private networks, and internal/external network separation are commonly used to protect data integrity. At the same time, top-level regulations are needed to balance security and operational efficiency. A lack of unified standards and private networks remains a challenge. Different jurisdictions often operate on separate networks, making cross-provincial or inter-regional remote interrogations difficult. Moreover, many systems lack networking capabilities, leading to fragmented management and limited scalability. Technology in public security, procuratorates, and other agencies lags behind, with many systems still using outdated analog equipment. This leads to low-definition video, which hinders evidence collection and presentation. There is also no universal agreement among manufacturers regarding product compatibility, despite compliance with international H.264 standards. Despite these challenges, the market for remote interrogation is growing. Companies like Hangzhou Wing Control, Suzhou Keda, Tiandi Weiye, and Guangzhou Aoweiya are developing tailored solutions that address specific needs. These systems offer flexibility, security, and interoperability, helping to meet the evolving demands of the judiciary. However, the market is still mixed, with many non-professional products that fail to meet legal requirements. Some lack essential functions such as dual-channel recording, while others are poorly designed and pose security risks. Looking ahead, the road to widespread adoption of remote interrogation is long. Manufacturers must focus on improving functionality, portability, and usability. Establishing industry and national standards will be crucial to achieving interoperability and ensuring consistent performance across systems. In conclusion, remote interrogation represents a significant shift in how investigations are conducted. It improves efficiency, reduces costs, and supports the modernization of judicial processes. While challenges remain, the future of remote interrogation looks promising, with continued innovation and collaboration paving the way for broader acceptance and implementation.
