We hear a lot about the Internet of Things, and more and more of them are connected to the Internet. However, in addition to the fact that these devices are connected to the Internet, they are also increasingly connected or controlled using various radio frequencies. These radio frequencies often use proprietary or unsecure protocols, so it is often impossible to disrupt the signal by intercepting it, but simply blocking it.
A recent case in Manchester shows that our dependence on RF can be very fragile. In this example, a thief broke into a vehicle using a simple car lock jammer, causing confusion in the parking lot, no one could unlock / lock their remote car lock, and eventually triggered multiple alerts.
North American car locks operate in the 315 MHz range, and in Europe and Asia, the 433 MHz range. Although signal gps jammer are illegal in most countries, there are many places where these devices are sold at these frequencies for about $ 50-200, depending on the range and manufacturing quality of the device.
I heard a lot about people who “cut the wires” and they said they were no longer connected to the cable. Even more disturbing is the fact that they brag to the public online through social media. This puts people at risk, and many ignore it. Potential thieves or home intruders are now being hit hard. If they’re even a little smart, they can take advantage when hacking into your home. Like car lock jammers, mobile phone jammers are illegal, but still easy to find.
The cell phone jammer battery can be purchased and sold by means they must be shipped to US residents and other countries, even if they are illegal online sites. Using a cell phone jammer may result in you being fined $ 20,000 or less. But if criminals can buy guns without a license, it’s not difficult to hold a phone jammer.
If a thief or intruder activates one of these devices from outside your home, your phone will no longer be able to receive signals and you will not be able to make any emergency calls for help. Many of these jammers also disrupt Wi-Fi, so you can easily turn off all communications inside your home with the touch of a switch on these devices.
Although more and more people are “cutting the power cord”, this has also caused problems for traditional alarm systems that rely on landlines. If the ground cable is cut, an alarm is usually triggered at an alarm monitoring station. Today, alerts can be wired over an Internet connection or use a cellular connection. However, both of these new approaches have problems. If the Internet or cellular connection decreases, the alert provider will usually not be alerted. Thieves can easily disconnect the Internet from outside the house, and we’ve seen what can be done using a cell phone jammer.
Many operators sell other home automation and security equipment and services, ranging from alarm systems to cameras and locks. However, when introducing mixers into a mix, especially as criminals become more familiar with the technology, the question arises whether these devices and safety measures work properly. These jammers can also disrupt industrial systems and block the reception of cells with a few grids with sufficient power. It is conceivable that such tactics can not only be used by criminals, but also be developed into means of attack.
