Mobile phone security signal jammer only works for mobile phone communication, no interference to other electronic equipment, harmless to human body, and can be widely used
1. Various conference rooms, auditoriums, courts, libraries, examination rooms, schools, theaters, hospitals;
2. Gas stations, gas stations, oil fields, oil depots;
3. All places where the use of mobile phones is prohibited, such as government, military, finance, securities, prisons, public security or command centers.
1. Mobile phone security signal jammers are all composed of the latest SMD components and integrated circuits. They have advanced performance, easy installation and use, and can work continuously for a long time.
2. The production process strictly follows the ISO9001 quality system, and the work is stable and reliable. It is an ideal and reliable safety product to strengthen information security, ensure safe production and protect the environment.
3.1 Main functions
1. The signalstorer electronic technology shield can effectively shield CDMA, GSM, DCS, PHS, 3G, 4G mobile, China Unicom, telecom mobile phone signals, WIFI Bluetooth wireless audio and video, wireless cameras, UHF, VHF walkie-talkie signals, wireless invisible headphones, wireless network cards, no Bone earphones, homemade communication equipment and other cheating signals.
2. Only shield the mobile phone signal, does not affect the normal operation of other electronic equipment
3. Under normal circumstances, it is best to use places 200 meters away from the base station.
4. It can work stably for a long time after connecting to the power supply
5. The slow start circuit design can avoid the spark phenomenon caused by the mechanical switch
3.2 Main technical indicators
1. Effective shielding diameter: 5-50 meters (depending on the signal strength of the local environment)
2. Shielded signal bandwidth:
GSM: 925-960 MHZ
WIFI Bluetooth: 2400-2500MHZ
Where are cell phone jammer mainly used? And product technical parameters, installation precautions
3. Working hours: 24 hours, 365 days, uninterrupted and stable work for a long time
4. Ambient temperature: -40℃ to +55℃
5. Relative humidity: 30% -- 95%
6. Power adapter: input AC 110V – 240V output DC 5V
4.1 Installation steps and methods
1. Take out the shield main unit from the box;
2. Screw the antennas into their corresponding antenna bases, otherwise it will be invalid;
3. Hang the shield on the wall or the corresponding position, the best installation height is 1-1.8 meters;
4. First connect the 5V output of the power supply to the host, then insert the AC input of the power supply into the mains socket, and then turn on the power switch, the work indicator on the power supply is on, indicating that it starts to work.
5. For the installation location of large and small spaces, the method of selecting points is shown in the following figure.
Example 1: Small indoor space (less than 200 square meters)
Example 2: Large indoor space (more than 200 square meters, multiple units must be used)
Example 3: Large outdoor space (more than 1000 square meters, the best effect is to use multiple honeycombs)
1. The antenna must be installed according to the corresponding mark on the host, and then connect the power of the host.
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.
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. 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.
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.
6. When using the shielding device outdoors, pay attention to waterproofing.
7. When the area of the site used is larger than the effective shielding range, it is recommended to use multiple shielding devices for cellular installation to ensure the shielding effect.
8. Since the power supply and antenna are dedicated to the host, and they are debugged one by one when they are debugged at the factory, please try not to use them interchangeably to ensure the best effect.
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.
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 appear.
