Remote Interrogation of Popular Blockers

Remote Interrogation of Popular Blockers

What is remote interrogation? Remote interrogation refers to the use of network video technology to communicate with voice and video image transmission channels and terminal equipment established on the network in the same situation where the investigators are not located in the same premises as the suspects. The entire process of interrogation is completed so as to realize the interrogation mode of interrogation. After the interrogation was over, the interrogation transcripts were sent to the suspect's local procuratorate through the procuratorate network, printed out by the suspect's local procuratorate, handed over to the suspect for verification and signature confirmation, and the audio and video materials were also generated and indented by the prosecutor's office at the suspect's location.

Compared with traditional methods of interrogation, the most important feature of remote interrogation is that investigators can interrogate criminal suspects without directly contacting them, thus bringing great convenience to investigators and criminal suspects. The use of remote interrogation not only enhances the efficiency of interrogation and expedites the investigation of cases, but also saves costs, optimizes judicial resources, and complies with the principles of trial economy and interrogation.

The popularity of long-distance trials has just embarked on the journey. Among the three industries under the Public Security Law, the construction of digital courts at the courts is fast, and the construction of digital interrogations at public security and procuratorates is relatively slow. Since 2013, there has been continuous demand from the court for remote trials. The public security and prosecutor's offices have also begun to plan the construction of a remote trial system while building a remote review system in court. There are two main types of applications related to interrogation services: one is localized synchronized audio and video applications; the other is remote interrogation applications. Localized synchronous recording and recording are divided into fixed-site synchronous recording and portable synchronous recording and recording. Remote interrogation applications also include remote telephony, multi-party trials, and remote interrogation applications.

Among them, the public security interrogation service is divided into two parts. One is the interrogation/inquiry room for the case handling center at all levels of public security agencies (including police stations), and the other is the interrogation/agency room for each detention center. The remote interrogation command system used by the Procuratorate is relatively different from the remote interrogation system. The remote interrogation must transmit the image video and sound from the arraignment end to the front, display it on the display in real time, and play on the speakers synchronously. Remote command requirements can communicate with the front-end using text, voice, or video, and business process differences are also large.

A court-like business is called a "digital trial," and the application is mainly court. The court is also actively using remote interrogation systems to interrogate criminal suspects. The Supreme People's Court conducted an in-depth investigation and demonstration and officially launched a remote interrogation work in 2009 to explore a remote interrogation model suitable for the trial of the people's court and standardize the working procedure for remote interrogation to ensure The quality and safety of the mention. At present, remote trials have covered the courts in most parts of the country, and the convenience and efficiency it brings have also received increasing attention.

Long-distance interrogation of popularization: The current network interrogation system has entered the high-definition era. In the process of remote interrogation, the interrogation devices in the two places must encode and decode their own high-definition video and achieve real-time interaction. The data transmission is the largest. Problem: In remote interactions, insufficient bandwidth will affect the entire interrogation process. Video will show mosaics, data loss, large interaction delays, etc.; based on the current status of network bandwidth, it will lead to restrictions on the number of remote video channels for application, especially HD. video. At present, only the public security law departments in developed regions will build long-range interrogation systems, while other regions will only build local model interrogation systems.

Network security As long-distance interrogation signals are provided through the judicial network to provide private network transmission, manufacturers can only access the system through the IP port provided by the judicial department. Therefore, interrogation record files cannot be interfered by manufacturers during line transmission, and its security is on the one hand operated by the judicial system. Organs use encryption, virtual private networks, and internal and external networks to ensure network security technologies. On the other hand, manufacturers conduct the post-encryption processing of the stored interrogation documents. At the same time, the state also needs to establish rules from the top-level design to weigh the balance between security and work efficiency.

There is no unified private network and unified standards. Public security, procuratorates and courts all have their own private networks. The standards between jurisdictions in different regions are not necessarily the same, so remote interrogation between provinces and regions has not yet been completed. The simultaneous recording and recording system of the judicial organs also requires the function of networking, not only can the system be uniformly managed, but also a series of business extensions. However, many networked functions of the synchronous recording and recording system cannot be realized. When centralized management is required, the equipment room is independent, so it is impossible to achieve unified control, unified management, and centralized backup storage.

The technology is lagging behind in the public security, procuratorates, discipline inspection commissions, customs, and other agencies, and it has long been necessary to build a synchronized recording and recording system. However, due to the lack of unified construction from top to bottom, the construction scale and construction process in various parts of the country are often not uniform. On the other hand, because the judicial market is relatively closed and the technology is updated slowly, resulting in relatively lagged technology and low definition of analog images, the crime details cannot be fully displayed when evidence is collected, and effective evidence display cannot be achieved.

There is no unified agreement on products. The agreement among different manufacturers, especially the encoding and decoding of audio and video, although all comply with the international H.264 standard, but there are nuances between the manufacturers, can not be a good interconnection and interoperability.

The emergence of the Internet has always been to break the traditional pattern of all walks of life, and now network technology has penetrated into all aspects of life. The so-called wine fragrance is not afraid of a deep alley, if the right time for good things meets, it can always generate unlimited business opportunities. With the continuous development and evolution of network technology and the combination of market demand, a thing that will bring about changes for traditional interrogation was born. It is -- long-distance interrogation, and the guest officer sees the application of remote interrogation today.

The product market is mixed and the function is still to be improved. In the synchronous audio and video market, it can be said that there is a mixed bag of good and bad, both good professional products and many non-professional products. Although these non-professional products are inexpensive, they do not meet the requirements of judicial interrogation, and there are many potential safety hazards. Some of them are DVR or NVR modifications that cannot achieve synchronous recording and dual-disc simultaneous recording.

Due to the existence of price competition in the market for synchronized audio and video recording systems, some manufacturers often only have the most basic simultaneous audio and video recordings in order to meet the minimum requirements of the judicial organs such as the Public Prosecution Law. However, their functions are not perfect and cannot achieve functional integration. , can not meet the needs of modern audio and video synchronization.

The lack of serialized products: Public security, procuratorates, discipline inspection commissions, customs, etc. The demand for security products is diversified. Not only are there products that are deployed in separate interrogation rooms (talk rooms), but also products that can be networked and extended. , Outgoing portable products are also needed. However, it is difficult for products on the market to provide serialized products and cannot meet the differentiated needs of the judiciary. Therefore, some organizations tend to purchase products that are not produced by one manufacturer, which leads to problems such as compatibility and upgrades.

For the personnel of the judiciary, there is a demand for the field. It is very convenient at this time to have a portable audio and video recording system. However, there is a lack of portable products that are truly suitable for carrying on the market. Some mobile devices are not only bulky, not easy to carry, and the installation of devices is complicated, which seriously affects the quality and credibility of the entire process of recording audio and video.

The legality of electronic transcripts is to be confirmed. After the system is applied to simple cases, the interrogation transcripts are transmitted to the suspect's local procuratorate through the procuratorial network, printed out by the suspect's local procuratorate, submitted to the suspects for verification, signature verification, and audio recording. The information was also generated and inscribed by the prosecutor’s office in the location where the suspect was located, and was handed over to the criminal suspect for sealing. However, the current legality of electronic records, electronic signatures, etc. as evidence is not recognized. At present, remote trials are only applicable to cases where the circumstances of the case are relatively simple and the circumstances of the case are not complex, mainly to meet the needs of remote audits and reviews.

Remote interrogation solution providers have their own strengths. Hangzhou Wing Control - based on simultaneous recording offerings Wing Control is one of the earliest vendors to conduct interrogation/synchronous recording and video products and solutions. It began to cover this area in 2005. For many years, Evermore focused on providing judicial remote review solutions. Its focus is on optimizing the remote trial experience on the site, simulating the realism of the on-site trial, and fitting the interrogation room to optimize the acquisition of live video and audio.

Openness: Yong-Chang Juyi system is basically compatible with the mainstream hardware products in the market. Differentiation: The business processes and requirements of different judicial units are not necessarily the same. Ever Control develops the corresponding system version for different units. Security: Stream encryption technology is used to encrypt the video. The video can only be played through a professional player and username and password.

Suzhou Keda - Flexible Solution Based on Security Surveillance and Video Conferencing Coda is one of the earliest manufacturers of interrogation/synchronized audio and video products and solutions. It can provide a variety of fixed and portable flexible solutions.

The fixed-type synchronous recording and recording system can realize the characteristics of long-distance networked applications, flexible combination of products, etc.; the narrator's simultaneous recording and recording system can provide convenient installation and convenient operation through a fixed product combination; portable synchronous recording and recording system is mainly used Satisfy the needs of public security and prosecution agencies handling temporary cases. Keda's greatest advantage is its deep industry background for audio and video synchronization technology. In particular, there is a clear advantage in long-distance network interrogation applications. Professional multi-view video and audio processing technologies can be used to solve common problems in conversations, such as asynchronous audio and video, echoing whistling, and so on.

Tiandi Weiye Digital Technology Co., Ltd. - Providing a plan for the background of security monitoring companies Tiandi Albert has a large number of application cases in the procuratorates, courts, and prisons. Its biggest advantage is to get involved earlier, deeper study of judicial needs and better judicial channels.

Based on the basic functions of local and remote picture overlay, audio mixing, and echo suppression, Tiandi Albert can achieve multi-level networking, data resource sharing, and mutual review in different places across the province. At the same time, the system has the business functions of electronic transcript remote confirmation, remote fingerprint overlay, electronic signature, and remote electronic demonstration that are close to the actual needs of the case. And can be interconnected with all major digital court systems to achieve multi-level networking, remote live broadcast. At the same time, it has rich business functions such as remote court preview and tripartite review.

Guangzhou Aowei Ya - known for its software development in the fields of video and audio capture and transmission, image recognition, etc. Guangzhou Aoweiya Electronic Technology Co., Ltd. is one of the software R&D and product manufacturers specializing in video and audio capture and transmission, and image recognition.

Oveya has deployed a remote call room system in the procuratorate and a remote teleconsultation integrated management platform in the prosecutor's interrogation command center to achieve remote teleconference between the command center and the remote call room. Through the customized development of remote telex integrated management application platform software, a remote telecommissioning technical specification was established to effectively manage and apply the equipment of the two subsystems (remote interrogation room and local interrogation (inquiry) room). The long-distance high-definition interrogation host in the remote interrogation room and the local interrogation (inquiry) room can be used as a remote device or as a local device, without the need for duplicate investments to purchase equipment for interconnection and interoperability. In addition, the trial based on the long-range inquiries between the court's local high-definition digital court and the detention center was also a distinctive application of Aoweiya, which enabled a remote trial based on a remote commutation and parole case between the court's local HD digital court and prison.

The Road to Popularity It takes a long way to go. Manufacturers must design products that meet the needs of users. They must address issues such as video and audio transmissions at low bandwidth, complete functions, serial product development, portability, and operability. At the same time, it actively establishes its own corporate standards and upgrades them to industry standards and even national standards. To vigorously promote their own corporate standards is the way forward for companies to promote industry standardization. Judicial authorities can use remote interrogations as a judicial practice to provide the basis and reference for future legislation. At the same time as soon as possible to all manufacturers of transmission agreement unified and standardized, the establishment of a unified national network, and ultimately achieve interoperability between manufacturers, government agencies, resources sharing.

Remote interrogation is of great significance to reforming the interrogation method, improving the efficiency of interrogation, and reducing the cost of the judiciary. It will be the trend of the informatization construction of the public prosecution law department. Of course, some regional equipment construction investment and procurement differences, the judicial network standard and product agreement standards will become the biggest stumbling block for long-distance interrogation. There is still a long way to go before the popularization of remote interrogation.

A treatment plant for lake Kinneret water, comprising treatment by two filtration steps, flocculation and disinfection with chlorine dioxide, was studied with a view to evaluating the effect of ClO2 disinfection on drinking water quality and determining the optimal mode of operation for the treatment plant. Four modes of operation were studied and the optimal mode was defined as that in which the flocculant (aluminium sulphate) was introduced before the first, and ClO2 after the second, filtration. The finished water contained a residue of approx. 0.2 mgl−1 ClO2, approx. 0.35 mgl−1ClO2− and low concentrations of suspended matter (1.5 mgl−1) and of chlorophyll (0.1 μgl−1). Trihalomethane concentrations were negligible, and the bacteriological quality of the water was within the health authorities' requirements. It was shown that disinfection of treated water (after flocculation and filtration) was much more effective than that of raw water. Furthermore, disinfection in the optimal mode prevents accumulation of high chlorite concentrations leaving a residue of ClO2.
