Overview
In order to meet the needs of the new situation, improve prison science and technology prevention capabilities, strengthen prison science and technology management, promote the construction of digital prisons, promote the harmonious and stable development of prisons, and continuously improve the modernization level of prison work, it is necessary to scientifically and effectively control and control mobile phone signals in prisons. Prevent and eliminate potential safety hazards caused by illegal use of mobile phones.
Current status
According to the relevant regulations of the Ministry of Justice and the spirit of the documents, prisons across the country have had an urgent need to establish mobile phone shielding systems in recent years, and many prisons are preparing to initiate projects or have already started construction. Looking at the current situation: some units have adopted high starting points and strict requirements. Through long-term market research, they have learned relevant successful experiences and lessons from failures, and organized relevant experts to provide technical explanations and questions for various brand companies and demonstrate the actual shielding effect of the products. Currently, Shanghai Prison More than 92% of the prison shielding projects of the Administration have finally been selected by the best brand companies to undertake them, and preliminary results have been achieved. However, due to many reasons, the expert group found that a large number of prison shielding systems across the country are not effective. Some of the systems have been completed but are not functioning properly, which has become a thorny problem for prisons and engineering contractors.
Several main manifestations of poor performance
1) The shielding effect of the shielded area is not strict, and there are a lot of blind spots and dead corners. Mobile phones can be connected in many areas near the windows of some prison areas, especially on the side in the direction of the base station, and even under certain antennas (devices). Calls leave opportunities for criminals and fail to achieve the purpose of comprehensively preventing illegal use of mobile phones.
2) Severe interference in areas that should not be shielded: Office buildings, armed police and other areas outside the second gate of the prison are severely interfered, affecting the normal life and work of staff; more serious interference will further expand the scope and even interfere with base stations to paralyze them. Large areas of communities, factories, and units have been subject to strong interference, and people are very resentful. They have received complaints from residents and operating departments such as China Mobile, China Unicom, and Telecom, and have been investigated and dealt with by the local radio management department. These problems have had a certain negative impact on the normal work of the prison. , disrupting the harmony of police-community relations.
3) System operation is unstable: good and bad, low reliability, and frequent failures. Especially in summer and autumn, a large number of equipment malfunctions and damages occur. Although a large number of equipment have been replaced, the expected shielding effect cannot be achieved; instead, constant maintenance is wasted, which is useless and wastes time and money. Four. several main reasons https://www.silencejammer.com/
subjective understanding
1) Lack of correct and comprehensive understanding of the essential differences between prison blocking systems and common civilian mobile phone jammers on the market. The prison shielding system is a perfect organic combination of comprehensive technologies and product indicators such as communication technology, radio wave transmitting and receiving technology, electronic countermeasures technology, equipment performance indicators, etc. It is not a simple distributed use of a large number of general civilian mobile phone jammers.
2) Lack of systematic comprehensive and scientific analysis of cost performance and input-output ratio. People usually propose investing the minimum amount of money to produce maximum results, but they ignore the basic and reasonable investment in product technology. They even purchased and used low-end equipment products that were fundamentally unable to meet the technical requirements of prison projects, which had inherent shortcomings and left endless hidden dangers in the future.
3) Some corporate marketing staff, driven by immediate economic interests, exaggerate the company's strength and product quality, make promises that they do not understand and cannot achieve, and rely on their good social skills and customer relationships to make up for problems if they occur in the future. The hope of problems with the product itself (even some equipment suppliers know that the product itself has serious defects).
Equipment itself
1) At present, many domestic shielding equipment production and sales companies have not invested a lot of manpower and financial resources in product development and application, and key technologies have not been improved accordingly. Instead, they adopt OEM, imitation, low-cost, low-performance, low-price strategies. Mass production and selling, relying on widely exaggerated marketing propaganda, have achieved certain profits in situations where the general civilian market has low requirements. At the same time, they want to occupy a place in high-standard, high-demand, and high-reliability market areas such as prisons, but in the end they will inevitably give up to prisons. Cell phone blocking systems bring immeasurable losses.
2) Reasons for design, installation and debugging: Many companies undertaking shielding projects lack basic technical support for large-scale projects such as prison mobile phone shielding, do not have considerable professional knowledge and rich application experience, lack necessary testing instruments and equipment, and blindly rush implementation, or even Some designers refer to the effective shielding range in the product manual for design distribution without knowing the reason, and the installers only complete the equipment fixation and power-on work. When it is found that the shielding effect is poor, the method of simply increasing the number of devices is used to achieve the shielding effect. Focusing on one thing at the expense of the other will eventually lead to the project not being completed.
Responses
1) Raise awareness of the essential differences between prison cell phone shields and general civilian jammers. It is necessary to fully understand what basic shielding is, what strict shielding is, why civilian products cannot be used in professional fields, what kind of products are professional products, what is the difficulty of prison shielding, etc.
2) Conduct detailed market research, such as online searches, to understand relevant success and failure cases in the same industry, and fully communicate with technical personnel of relevant companies to choose products with strong technical strength, advanced product technology, stable quality, good corporate reputation, and brands. Relevant cooperation has been carried out with companies and product brands that are well-known and can provide a large number of successful cases. Of course, under the strict guidance of the prison authorities, relatively good results can also be achieved by entrusting local and reliable system integrators to conduct in-depth research and implementation.
