But please note that if you have a webcam, it may also be used to monitor you, which is much easier than using a Raspberry Pi. If you combine the Raspberry Pi, camera and its wifi jammer, you […]

As we have already mentioned, the connection between the helicopter and the smartphone is the most vulnerable place here, and we will use it to disable the MeCam helicopter. It uses the 2,4 GHz frequency, which has been widely used for Wi-Fi and Bluetooth, and we were able to stop it. All you need to […]

The wireless monitoring system is very good because it is really easy to install. You don’t need to put a lot of wires around the house, because all cams can be connected to the receiver via radio frequency, and its working range can reach 500 feet. The only problem here is that they use the […]

In this case, it is best to avoid using the device or use it with a wifi jammer. This ensures that even if your phone or tablet is hacked, no one can use it to hijack your car. In addition, since Wi-Fi and Bluetooth have been widely used for smartphone hacking, this simple measure can also […]

As you know, you cannot easily limit the propagation of radio waves, so you can intercept the signals you exchange with Wi-Fi hotspots.

You know, this may sound interesting and ridiculous, but we at Perfectjammer are pretty sure it can be done. Scientists at iBionics have created a way to control cockroaches through radio signals. They choose cockroaches because they are small, durable and can crawl almost anywhere. Another reason is that these bugs can survive in harsh […]

The new API Google Maps Geolocation does not use GPS to get your location. The location technology is based on cell tower triangulation and identification of the closest Wi-Fi hotspot. As long as the program uses Google’s database and knows the coordinates of these hotspots, it is possible to calculate your hotspots. You can read […]

UBI is a voice-controlled computer, just plug it into the wall to start working.

If you need to plug the device, there are two ways. Both of them are indeed at work and are completely and not partially in trouble. You can try to block 2G, 3G and 4G at the same time so that MiFi 4620LE cannot connect to any network, or you can try to block the […]

These MiFi devices are very popular because they can be used to share Internet connections with others. You can connect Verizon’s MiFi hotspot 4620LE to your phone and connect to a 4G or 3G network. If you share 4G Internet, MiFi hotspot 4620LE can support up to 10 users. If it is 3G, you can […]

Now, by running this device (seriously, don’t buy any kind of device) and verifying whether the malicious behavior has been advertised, the federal law has been violated for a few minutes, all you have to do is to open it and find out, this How it works. I certainly didn’t expect much of the $8 […]

Although the average altitude of GPS constellations is 20,200 kilometers (12,550 miles), which may not be as high as the average altitude of communication satellites in geosynchronous orbit, they still have a long way to go. Given this incredible distance and the size of the antenna on most GPS-equipped devices, it is no wonder that […]

James Katz, director of the Mobile Communications Center at Rutgers University, said: “If there is one thing that defines the 21st century, it must be our inability to control ourselves for the benefit of others.” “Those who call think that they have more rights than those around you. People who carry jammers think their rights […]

One afternoon in early September, an architect jumped up on the train when he heard a woman in her 20s talking to someone on the phone, which he thought was “lively.” Architect Andrew said: “He used the word’many times’.
