The mobile communication jammer targets the uplink and downlink channels of the mobile phone system, using techniques such as frequency multiplication, frequency division and frequency hopping filtering to analyze the required shielding frequency. . When the shielding instrument is in working condition, a spherical shape is customized according to the power of the shielding instrument.The shielding of the space makes the mobile phones in this space invalid, unable to receive and call , so as to achieve the goal of forcibly banning mobile phones. Using ultra-high frequency broadband interference technology. Smart remote control technology controls the output power with a remote control range of 10 meters. High effective power, large interference radius and adjustable range. Using advanced filtering technology, efficient segmentation, will only interfere with the downlink, will not cause interference to the base station. The slow start circuit design can avoid the ignition phenomenon caused by the mechanical switch, with high integration and stable operation. The four frequency bands are designed independently, do not affect each other and provide stable and reliable performance. The design of the metal shell is solemn and beautiful. It can be widely used in various professional secrecy places, flammable and explosive professional places and professional operation places to deactivate mobile phones.
Recording cell phone jammer is a device used to protect recordings in a specific environment. It can actually interfere with the recording equipment of tape recorders, cameras and digital headphones. It can effectively interfere with digital voice recorders and tape recorders with a frequency of 100HZ-20,000HZ. By emitting white noise outside the frequency range of human hearing, the voice recorder or tape recorder can only record a piece of "buzzing" noise, and the conversation content of the speaker cannot be recorded. cannot be recorded, and the recorded voice cannot be restored after post-processing sound. Sound (because the sound captured by the recording device is just noise). In order to effectively protect the content of the conversation from secret recording. At the same time, the wifi jammer of the recording device makes no visible sound while working. This may interfere with the recording of all tape recorders. The best interference distance is 6 meters in radius, and the effect can reach 90% at 8 meters. The effect can be as high as 85% at 10 locations and 75% at 12 yards. Only noise is recorded. The test proved that as long as it is a capacitive sensor, it can interfere with sound. Therefore, it is proven that wired and wireless eavesdropping can interfere and prevent eavesdroppers from hearing sound.
