Mobile phone security signal jammer will provide you with a safe and quiet space and become your reliable and faithful guard!

I. Overview

In the information age, with the rapid development of communication technology, mobile phones have become an indispensable tool for people's daily work and life. However, the wide application of mobile phones has also caused some problems that cannot be ignored, mainly:

1.1 Become a new leak channel, posing a threat to the security of confidential information.

With the development of science and technology, the positioning, tracking and monitoring of mobile phones have become the most important means of reconnaissance and a source of security for all countries in the world. Therefore, as long as a mobile phone is carried in a secret-related place, whether it is used or not, as long as it is in standby mode, it is very likely to cause leakage of secrets, causing serious harm to units or individuals, and even to political parties and the country.

1.2 Become a new source of noise pollution and interfere with the normal working order.

With the increasing popularity of mobile phones, the environment of using conference rooms, courts, libraries, schools and other places is deteriorating. The noise generated by mobile phones destroys the quiet and serious atmosphere of these places and affects people's normal work.

1.3 It becomes a new unsafe factor, which brings hidden dangers to the safety production of enterprises.

The use of mobile phones in gas stations, gas stations, oil fields, oil depots, etc. will cause fire or explosion, and the consequences will be very serious.

1.4 It has become a new criminal method and has an impact on social stability.

Some opportunistic people use mobile phones to cheat in exams, and some terrorists and hostile elements also use mobile phones to detonate bombs... Facts show that mobile phones have become a tool for criminals to commit crimes on some occasions, which has a negative impact on social stability. . The mobile phone security signal jammer developed by our company can effectively solve the above problems. As a new type of information security product, it uses a specific electromagnetic signal to form an electric fence in the place that needs to be protected, so that the mobile phone cannot receive the base station data, and cannot establish contact with the base station, thereby eliminating the negative impact of the mobile phone. to safety protection.

3.2 Main technical indicators

3.2.1 Effective shielding diameter: 30-100 meters

3.2.2 Working hours: long-term uninterrupted and stable work

Fourth, matters needing attention

4.2.1 The antenna must be installed according to the corresponding mark on the host, and then connect the power of the host.

4.2.2 The effective coverage of the shield is a circular area centered on the shield, so pay attention to the correct placement of the shield when using it to avoid dead corners.

4.2.3 The shielding device should be placed in a well-ventilated place, try to avoid the shielding of large objects, and avoid strong electromagnetic sources of strong heat sources, so as to ensure the shielding effect and long-term stable operation.

4.2.4 When the shield is working, do not stack other items on it and disassemble the antenna, so as not to affect the shielding effect and damage the machine.

4.2.5 When the shielding device is not in use, the power supply should be cut off in time, so as not to affect the normal use of the mobile phone.

4.2.6 When using the shielding device outdoors, pay attention to waterproofing.

4.2.7 When the area of ​​the site used is larger than the effective shielding range, it is recommended to use multiple isolators for cellular installation to ensure the shielding effect.

4.2.8 Since the power supply and antenna are dedicated to the host, and they are debugged one by one during factory debugging, please try not to use them interchangeably to ensure the best effect.

4.2.9 Please keep away from corrosive gases and liquids, and do a good job of dustproof and moisture-proof, so as not to accelerate the aging of the internal components of the equipment.

4.2.10 When placing it outdoors or in the wild, attention should be paid to adding protective devices to the environment where destructive animals such as rats and ants are infested.

5. Maintenance

5.1 The shielding device is a maintenance-free device and requires no maintenance.

5.2 When wiping the surface, do not use chemical solvents, and avoid water entering the machine.

5.3 When the shield is useful, it should be stored in a dry and ventilated place to avoid prolonged exposure to salt mist and harmful gases.

6. Answers to questions

6.1 When the mobile phone security signal jammer is working, why some mobile phone signal indicators still have signal indicators?

A: This is just an illusion. In fact, the mobile phone has been unable to communicate at this time. When you press the unplug button at will, you will find that there is no signal indication on the signal indicator.

6.2 Will the mobile phone security signal jammer interfere with the normal operation of other electronic devices?

Answer: No. This is because the electromagnetic signal emitted by the mobile phone security signal jammer completely falls within the working frequency band of the mobile phone stipulated by the state, which will only block the communication of the mobile phone. And this signal is always in a relatively static state and will not affect any electronic equipment.

6.3 Are mobile phone security signal jammers harmful to human body and mobile phones?

Answer: Please rest assured that the strength of the electromagnetic signal emitted by the mobile phone security signal jammer is very weak. The test data shows that the strength of this signal is far from harming the human body. At the same time, the mobile phone security signal blocker only blocks the forward signal of the mobile phone, so that the mobile phone cannot contact the base station, so it will not cause any damage to the mobile phone itself.

6.4 Is there any difference in the working distance of the mobile phone security signal jammer when it is used indoors and outdoors?

Answer: Yes. The effective distance (30-40 meters) of the mobile phone security signal jammer generally refers to the indoor distance. In outdoor open areas, the effective distance of shielding can reach several hundred meters. It should be pointed out that whether it is used indoors or outdoors, the effective working distance of the shield has a certain relationship with the environmental conditions at that time, such as the distance from the base station and the placement position. Therefore, when using a mobile phone security signal blocker, this factor should be fully considered to avoid blocking dead corners and affect the shielding effect.

6.5 Does the mobile phone security signal jammer have the same effect on GSM mobile phones and CDMA mobile phones?

A: This is a good question. Since the anti-interference performance of CDMA mobile phones is far better than that of GSM mobile phones, the effective shielding distance of mobile phone security signal blockers for CDMA mobile phones is smaller than that of GSM mobile phones, but the difference is not very large, about 2-4 meters. However, users are also reminded that in some particularly important places, the number of mobile phone security signal jammers should be increased if necessary to ensure the shielding effect of CDMA mobile phones.

6.6 After the mobile phone security signal jammer works for a period of time, the casing becomes hot. Will it damage the machine after working for a long time?

A: This is a normal phenomenon. In terms of design, we use the thermal conductivity of the aluminum alloy wire drawing case to assist in heat dissipation. This ensures long-term stable operation. Therefore, a hot case will not damage the machine.
