Here you can find your own jammer

The Los Angeles Police Department has issued a warning to residents regarding the increasing use of WiFi jammers by thieves. These jammers are being utilized to effortlessly disable "connected" security cameras and sirens. It is worth mentioning that these jammers can be easily obtained from online marketplaces such as Amazon at affordable prices.

The use of WiFi jammers by tech-savvy criminals has become a cause for concern, as reported by Los Angeles news station KTLA5. These compact devices have the capability to disrupt wireless devices and overwhelm them with excessive traffic. This worrisome development allows thieves to enter homes without setting off alarms, highlighting potential weaknesses in security devices like Ring and Eufy when it comes to protecting affordable housing.
Last month, Tom's Hardware brought attention to the issue of criminals using WiFi jammers, a practice that has been ongoing for several years. These devices are easily accessible for purchase online and are priced affordably at $40.
In the United States, the use of these is deemed illegal, albeit from a technical standpoint...

The Federal Communications Commission (FCC) issued an alert in 2020, emphasizing that the deliberate use of phone jammers, GPS blockers, or any other signal jamming devices to intentionally disrupt or interfere with authorized radio communications is against federal law.
Nevertheless, it seems that these alerts were not heeded. Just last month, police in Minnesota uncovered that nine robberies over a six-month period were facilitated by wifi jammers. Thankfully, the burglars are still choosing to target unoccupied homes without resorting to violence.
Given the latest situation, the Los Angeles Police Department is urging homeowners to prioritize hardwiring their alarm systems over relying solely on WiFi. Moreover, they are stressing the significance of maintaining proper illumination for residential properties during nighttime.
Additionally, the LAPD advises individuals to ensure that their absence from their residence for a prolonged period remains unknown to others.
Cell phones act as two-way radios that communicate through cell towers. cell phone jammer function by transmitting a robust signal on the frequencies utilized by mobile devices, disrupting communication between the device and the cell tower. This causes the mobile device to lose functionality and display "No Network".
Cell phone jammers prevent and disable any mobile phone communications from entering specific areas of a building or open space to

1. Mitigate the risk of industrial espionage by implementing robust measures to prevent the misuse of mobile devices as eavesdropping devices or for capturing images through cameras (phones).


2. Efforts to counter terrorist threats involve tackling the issue of remotely detonating bombs in high-risk areas.


3. It is imperative to remove public nuisances from places like movie theaters, restaurants, and churches.

Diverse in sizes and shapes, this product offers a variety of options. From pocket-sized alternatives to larger ones, there is something for everyone. Furthermore, certain models are skillfully camouflaged as regular cell phones or briefcases.
Things to consider before buying a cell phone jammer:

• What is the effective interference range (more than 10-50 meters)


• Which cellular systems can it block (cdma in north america, gsm in europe and asia, tdma, 4G, 3G, pcs, dcs or all?)


• How many cellular systems (cdma etc..) it can block simultaneously (low-end models can only block 1 type at a time, while more complex models will block multiple systems at a time)


• Appearance: Regular device or one disguised as another type of device?


• Dimensions and weight

Security forces are utilizing technology originally intended to prevent eavesdropping and thwart phone-triggered bombings to block ringing cell phones.
The reporters were the ones who first became aware of the situation. While they were engaged in reporting on the extravagant weddings of celebrities, they discovered that their cell phones were not functioning at Sacred Heart. Upon questioning the priest about this issue, they learned that Israeli counterintelligence was the cause of the disruption.
In Monterrey, four churches have inconspicuously integrated Israeli-made
cell phone blocker, which are compact and resemble paperbacks, amidst their collection of religious artwork featuring the Madonna and statues of saints.
The loud and colorful ringing of cell phones is increasingly being stopped in places like religious sanctuaries, India's parliament, Tokyo theaters, and commuter trains, thanks to devices that were originally developed to assist security forces in preventing eavesdropping and stopping phone-triggered bombings.
Jammers were put in place in the Indian parliament as a response to politicians consistently ignoring calls to power off their cell phones, causing disruptions in legislative proceedings.
After uncovering instances of exam cheating through text messaging or photographing test papers, Italian universities decided to introduce blockers as a preventive measure.

After being imported as a personal favor for a priest, the devices from Netline Communications Technologies Ltd., a Tel Aviv-based company, are now being used by the four Roman Catholic Churches in this northern city.

The Rev. Juan Jose Martinez, a spokesperson for the archdiocese, highlighted the fact that there are still many people who do not grasp the concept that attending Mass means partaking in a sacred moment with God. Regrettably, the utilization of these small devices became an inevitable choice.
Each unit was purchased for approximately $2,000, and they possess the ability to be remotely activated and emit radio frequencies at a low level. Their purpose is to disrupt cell phone signals within a radius of 100 feet.
Cell phone users may receive a notification on their devices stating that there is "no service" or that the "signal is not available."
Wedding bells
Monterrey's Sacred Heart church, a baroque temple favored by Mexico's elite for weddings, had their blockers obtained by church officials two years ago.
The parish clerk, Bulmaro Carranza, noted that at weddings, cell phones would ring every five minutes without fail. This created a troublesome situation, as there were occasions when even the groom would overlook turning off his cell phone.

Unnoticed for an extended period, the devices only came to attention when reporters, who were present at the weddings, started registering complaints regarding the persistent failure of their cell phones.
Carranza stated that in light of the signal blocker becoming known to the public, priests from different regions in Mexico have been phoning him to learn how to acquire them.
At Sacred Heart, a device positioned at the entrance of the church and another near the altar are activated just before each Mass. Nonetheless, the priests consistently urge parishioners to silence their phones before the services commence, with the expectation that proper cell phone etiquette will eventually be embraced.
Martinez noted that The Rosario, San Juan Bosco, and Our Lady Queen of the Angels, as well as other Monterrey churches with the devices, attract wealthier parishioners.
Martinez pointed out that while the cell phone is indispensable for many, individuals should still uphold good manners and demonstrate respect for sacred places.
Margarita Escobedo, a practicing Catholic who diligently attends church services at least twice a week and actively contributes to the San Genaro church as a volunteer, openly embraces the idea of introducing jammers in her parish. Recognizing the increasing nuisance caused by cell phones, she believes that implementing jammers would help restore the sanctity and focus during religious gatherings.
It was mentioned by Escobedo that those who bring cell phones to church are not fully devoted to God. He highlighted the disturbance caused by unexpected noises such as birds chirping or techno music during prayer.

Charges have been brought against them for participating in computer criminal activity by supposedly causing disruptions to the network as requested by their companions.
Authorities announced on Monday that two 14-year-old boys are facing charges for intentionally interfering with their school's Wi-Fi network to skip exams.
As per NJ.com, New Jersey high school freshmen have been accused of engaging in computer criminal activity and conspiring to commit such acts. School administrators contacted the police last Thursday after the Wi-Fi network experienced multiple crashes throughout the week.

As per the information provided by Capt. Dennis Miller to NorthJersey.com, the administration of Secaucus High School reached out to the Secaucus Police Department to report that two students were engaged in a "scheme to disrupt the school's WiFi service whenever instructed."
Due to their status as minors, the names of these individuals have not been made public. They have been handed over to their parents and are scheduled to make an appearance in the juvenile family court located in Jersey City, with the exact date yet to be determined.

In a recent statement, Schools Superintendent Jennifer Montesano confirmed that the Wi-Fi has been restored and is operating smoothly. While she refrained from sharing specific details, she did acknowledge that an investigation uncovered two students who may have been responsible for the system disruption.
How did they do it?
A number of students shared with NJ.com their belief that the boys were employing a Wi-Fi interrupter program or app to overload the school's routers with traffic in a denial of service (DoS) attack. This attack led to the network crashing when students tried to log on for classwork or online exams.
A junior student from Secaucus High School revealed to the news outlet that she found out about the Wi-Fi problem when a friend informed her that one of the suspects had been requested to interfere with the signal during an exam.
It was done for both the exam-adverse and for fun, she said:

The motive behind his actions was to escape examinations and similar tasks. Moreover, one of the boys carried out this act on behalf of his friend, ensuring she would not have to undergo a test during the class. Undeniably, it constituted a significant prank.
Jamming phones, Wi-Fi and GPS is illegal
Some students were disgruntled – why should the whole class be disrupted because a few kids didn’t feel like squeezing out some brain juice that day? Others were impressed by the boys’ alleged technical acumen and sported more of a “Meh! Nobody got hurt” reaction, like this 10th grader:
It was unexpected to see someone as young as us, or nearly our age, achieve something like this.
People's education is being tampered with, although no harm is being inflicted upon anyone.
With respect to the first issue, it is recommended that those students do not place too much emphasis on their classmates' alleged technological proficiency. Despite the fact that gsm jammer are illegal to market, sell, or use in the US - except for authorized, official use by the federal government - they are readily accessible online for a few hundred dollars.
signal jammer are not just an inconvenience; they represent a dangerous hazard to public safety as they have the potential to block crucial emergency communications. cell phone jammer are unable to make a distinction between regular phone calls and emergency calls to family members or 9-1-1 responders. In a similar manner, GPS and wifi jammer disrupt both routine and essential communication services.
In the past, there was an incident involving a man who faced felony charges for intentionally interfering with the phone signals of his fellow commuters. His frustration with their conversations led him to take such action.
While it may be true that no harm was caused by the school Wi-Fi jamming, it is important for children to understand that this is not a harmless prank. The potential repercussions are significant and should not be taken lightly.

WBTV reports that CMPD has discovered instances where thieves have skillfully circumvented surveillance cameras during home break-ins, thanks to their use of technology.
Cell-jamming is the term used to describe the interference caused by an individual using a device to disrupt radio or wireless signals.
The Federal Communications Commission has made it clear that intentionally using a phone jammer, GPS blockers, or any other signal jamming device to interfere with authorized radio communications is a violation of federal law. It is essential to recognize that this prohibition applies without exception, regardless of whether it is within a business, classroom, residence, or vehicle.
Cell-jamming is possible from a device roughly 30 feet from the target, or household security cameras.


In a south Charlotte community, a video has emerged showing a suspect surreptitiously navigating through a yard during the nighttime. It is worth mentioning, though, that not all incidents have been captured on camera.
John Shocknesse, VP of Customer Operations for CPI Security, highlighted the need to address potential interference with wireless devices and the importance of implementing strategies to prevent communication disruptions.
In a split second, someone might show up on camera, but the presence of cell-jamming enables their swift disappearance through the mere act of flipping a switch or pushing a button.
In south Charlotte, CMPD has identified this as a recurring problem during residential burglaries.
Shocknesse acknowledged the lack of any such activity, highlighting the significance of being vigilant and equipped with the latest technology.
WBTV sought his opinion on which devices are more prone to cell-jamming.
Shocknesse pointed out that the issue arises primarily with older wireless devices that lack encryption.
He stated that newer security systems and surveillance systems are built with improved technology, such as encryption, to provide heightened security.
Shocknesse pointed out the critical role of cameras and onboard recording in ensuring that events are documented and can be provided to law enforcement if needed.
Additionally, he recommended that the most efficient way to prevent cell-jamming is to utilize up-to-date technology with encryption and to use a wired device instead of relying on Wi-Fi.
Effective measures to prevent break-ins at home include maintaining proper lighting, utilizing alarm systems, and ensuring that bushes are trimmed to a maximum height of three feet.

The Los Angeles authorities have revealed that a group of thieves has been outfoxing smart devices throughout the area.
A statement from the Los Angeles Police Department on March 4 highlighted concerns about a group in Wilshire using Wi-Fi jamming technology to deactivate surveillance cameras and alarm systems that rely on Wi-Fi.
The recent spate of tech-savvy robberies in California forms part of a wider trend of technologically advanced criminal activities occurring nationwide. In the past year, law enforcement authorities in Minnesota and Connecticut also issued cautionary advisories to residents regarding organized groups of thieves skilled in Wi-Fi jamming. These examples are just a fraction of the numerous instances reported.

KARE11 has reported that even though the Federal Communications Commission has prohibited Wi-Fi signal jammers jamming devices, criminals can still purchase them inexpensively. These devices do not necessarily disable other devices but rather overload the network they are connected to.
The intention behind these devices, as explained by cybersecurity expert Mark Lanterman, is to obstruct radio transmitters and create traffic congestion that hinders genuine communication.

He recommended that if you opt for a Wi-Fi camera for your front door, you should perhaps contemplate using a hardline camera inside your home. Wired cameras connected through Ethernet cables do not rely on Wi-Fi networks and are not vulnerable to interference caused by a wifi jammer.
It is strongly recommended by the Los Angeles police to have burglary alarm systems hard wired.
Tom’s Hardware states that while smart technology may be a contributing factor to the issue, it can also be part of the solution. It is recommended by officials to employ timers or smart home devices to simulate occupancy when you are not present. Furthermore, certain smart home technology is capable of notifying users in the event of signal or connection disruptions.
In addition, Tom's Hardware recommends connecting surveillance devices directly to your device for storing camera footage, rather than solely relying on a cloud storage system. This way, even if there is a Wi-Fi disruption, the footage will still be saved and accessible.
The LAPD promotes vigilance among residents through the practice of securing doors, enlisting neighbors to watch over their homes during absences, and reporting any suspicious behavior, including the presence of vehicles with temporary or dealer plates.

Mobile phones have become an indispensable tool for communication in the daily lives of individuals. However, there are specific situations where mobile phone signal jammers play a crucial role. This article aims to provide a comprehensive analysis of mobile phone signal jammers, covering their technical principles and application scenarios. By exploring these aspects, readers can develop a deeper understanding of the underlying technology and the value it brings.
How mobile phone signal jammer works
The primary function of the mobile phone signal jammer is to emit signals at the same frequency as mobile phone communication, but with higher power to interfere with the original signal. This interference signal will overwhelm or drown out the signal usually received by the mobile phone, preventing the mobile phone from communicating with the base station normally, thus accomplishing the objective of signal blocking.
Jammers emit interference signals that are designed to disrupt specific frequency bands, which often include GSM, CDMA, 3G, 4G, and even the latest 5G network bands.
cell phone jammer offer varying coverage ranges based on their power levels, with higher power translating to increased coverage.
Types of cell phone signal jammers
Tailored for personal or small-scale use, this portable jammer is compact and easy to transport, making it ideal for conference rooms and small offices.
With its high power output, this fixed jammer is perfect for deployment in schools, examination rooms, prisons, and other locations with varying requirements.
Bespoke jammers are made to order for particular requirements and settings, such as military operations, government institutions, and other secure venues.
The principle and application of GPS signal jammer
GPS signal suppressors produce electromagnetic waves of specific frequencies that interfere with signals coming from GPS satellites, resulting in GPS receivers being unable to accurately interpret satellite signals. This mechanism is similar to that of typical electronic jamming devices, but is concentrated on the GPS frequency band.
Portable GPS signal jammers are primarily designed for personal privacy protection, while fixed jammers are predominantly utilized in professional sectors such as the military and government, offering a greater power capacity and wider coverage.
The military has the capability to use gps jammer, which can disrupt enemy navigation systems, thereby impeding their ability to accurately determine positioning and navigate.
Certain individuals or businesses might choose to utilize GPS signal blockers to prevent location tracking and maintain personal privacy.

The AIIMS entrance exam has sparked a great deal of commotion, catching many off guard. However, the city university has implemented precautionary measures to avoid such incidents. While certain universities have installed jammers at entrances, others have opted for metal detectors or security guards. Nonetheless, only a few universities have taken the initiative to implement all of these measures. Jammers effectively detect mobile signals, thereby preventing students from resorting to unfair practices cell phone jammer.

The installation of jammers at the exam hall of Punjab College of Technical Education (PCTE) was carried out by Ms. Kang, the college's director, two years ago. This decision was made when approximately 900 students were undergoing their exams. Ms. Kang pointed out that the implementation of a disruptor could effectively resolve the issues faced by all individuals by disabling their cell range.
The director of Guru Nanak Institute of Management and Technology (GNIMT), HS Singha, stated that the implementation of two jammers on the campus three years ago has successfully deterred cheating. Furthermore, stringent physical verifications are conducted to ensure students do not have phones in their possession wifi jammer.
MS Saini, the principal of Guru Nanak Dev Engineering College (GNDEC), voiced concerns about students resorting to unethical means to achieve better academic results. He emphasized the challenges posed by the students' increased capabilities, making physical verification nearly impossible and necessitating the installation of 11 jammers on campus. Furthermore, the college has implemented three metal detectors and enhanced security measures at the entrance gates.
The head of Ludhiana College of Engineering and Technology, Pawan Kumar Gupta, stated that the institution had installed five jammers and two metal detectors on the campus approximately three years ago. He suggested that if other educational institutions adopted similar measures, the likelihood of cheating through technological means would be greatly diminished signal jammer.
Can mobile jammers in colleges stop cyber crime?
The prospect of prohibiting mobile phones on campus has caused a sense of unease among students at universities across the city. The Maharashtra government's higher and technical education department is contemplating this ban as a preventive measure against cybercrime in universities.
However, students were disenchanted by the perceived violation of their liberties. Lala Atole, a student at ILS Law School, argues that the proposed ban makes no sense gsm jammer.
"School authorities can impose stricter rules on the use of mobile phones in classrooms, but installing jammers will directly impact students' freedom," he said. Some students believe that installing jammers will not affect most students as they are addicted to gaming during classes. "If cell phones are banned and we can't even answer important calls, students might think of skipping lectures. How does that help students?"
A student from Garware College, Vedang Bhagwat, brought up a question. Despite students expressing their discontent with the decision, there is a division among university authorities regarding the proposal. The authorities are considering the installation of jammers in classrooms, but are hesitant to implement them throughout the campus.
Hrishikesh Suman, principal, Symbiosis College of Arts and Commerce, opined, "Jammers will definitely help prevent distractions during classes. However, outside the classroom, this may affect the internal academic communication with the teacher." Only by getting the power to control jammers, The authorities will welcome this move. "Signal jamming affects our security systems and hampers emergency communications. Also, students are not used to restrictions and this may do more harm than good," said Dilip Sheth, Principal, SP College. Teachers believe it would be more helpful for students to voluntarily refrain. “Students should voluntarily refrain from using mobile phones without our close attention,” added MMCC principal MD Lawrence. Some even favor the use of cell phones on campus.
Girija Shankar, vice-chancellor of Neswadia Business School, highlighted that disruptors are not a suitable solution, given the abundance of out-of-town students in Pune and the necessity for their guardians to contact them.

Authorities with the Los Angeles Police Department are warning residents in Los Angeles’ Wilshire-area neighborhoods of a series of burglaries involving wifi jamming technology that can disarm surveillance cameras and alarms using a wireless signal.
According to police, the burglaries typically involve three to four suspects who enter homes through a second story balcony.
Once inside, the thieves target primary bedrooms in search of high-end jewelry, purses, U.S. currency and other valuables.

“On many occasions, these suspects will have a getaway vehicle and driver to act as a look out,” authorities said in a community alert.
To deter these types of burglaries, authorities provided the following tips:

• Ensure your electrical circuit boxes are secured with a padlock to make it harder for thieves to tamper with alarm systems


• Never tell Uber, Lyft or taxi drivers or post on social media that you will be on vacation or away from home


• Stay alert for suspicious vehicles with temporary or dealer plates, as well as rental vehicles


• Share your cellphone number with trusted neighbors and ask them to clear your mail and keep an eye on your residence if you plan to be away


• Place cameras around the home and ensure that the alarm DVR is secure and cannot be tampered with


• Consider moving to an alarm system that is hard wired rather than running on a wireless signal


• Provide extra security such as a pole to sliding glass doors to eliminate easy opening


• Place tracking devices, such as Apple AirTags, on valuable items like jewelry boxes, purses or vehicles


• See what shrubbery or trees can be trimmed or cut to keep your residence highly visible


• Install proper lighting and security signage and always leave light on in your home, especially while away

Anyone with information on any of these crimes is encouraged to contact LAPD’s Wilshire Burglary Detectives at Wilshireburglary@lapd.online. Those wishing to remain anonymous can contact L.A. Regional Crime Stoppers at 800-222-8477 or online at L.A. Crime Stoppers.

A current advisory has been issued for anyone using wireless security cameras like "Ring" to secure their home.
A Detroit woman expressed disappointment as her Ring camera did not capture the moment her car was stolen from the front of her house. A local expert suggests that this incident underscores the increasing technological proficiency of criminals.
The woman reported that her car had been stolen from her driveway at the start of the month. After checking her Ring camera footage, she realized that there were missing hours.
The assertion by Chris Burns, the proprietor of Techie Gurus, underscores that security cameras which rely on WiFi for recording prioritize convenience over security. This is due to the vulnerability of WiFi signals to interference, potentially hindering the camera's ability to capture footage of individuals near your residence, a loophole that criminals are exploiting.
In Burns' opinion, considering wireless as a security measure is misguided. He pointed out that wireless signals can be easily jammed or blocked.
Those wrongdoers have the option to use this as a wifi jamming mechanism, or a deauther, which could have the dimensions of an Apple Watch.
If you are in close proximity, a deauther can overpower a WiFi system, causing the WiFi camera to halt its recording. This accessory is relatively inexpensive, with prices ranging from approximately $10 to $50. Conversely, a singal jammer is considerably more expensive, with costs ranging from $150 to $1,000.
Jammers are highly prohibited, thus making them elusive to acquire. However, a robust jammer can obstruct an entire street from being recorded on WiFi security cameras with a simple toggle of a button.
Ring's spokesperson emphasized in a statement that Ring device performance may suffer due to WiFi signal interference, a common occurrence with wifi-enabled devices. Customers facing connectivity issues are advised to contact Ring Customer Support for assistance.
How can customers protect themselves?
It was mentioned by Burns that genuine security can be maintained by always using hard-wired connections, like being plugged into ethernet.
The spokesperson from Ring confirmed their awareness of the problem, underscoring its rarity.
Burns highlighted the inverse relationship between the affordability of technology and the growing popularity of camera jammer. Therefore, it is crucial to keep the public well-informed about this phenomenon.

Feb. 16 started like any typical Friday night. My husband and I decided to stay home, grill chicken and make a salad for dinner. At about 6:45 p.m., we heard some loud rumbling overhead.
We walked onto the back patio, and two police helicopters were overhead – shining lights all over our property, and a recording echoed, "Police. You are under arrest. Stay right there and I won't shoot you."
As I looked across the fence, a swarm of armed members of the Phoenix SWAT Team with a few dogs were circling our property. One of the guys said, “Yeah, there’s a signal jammer right here.” He picked it up. I leaned over the patio and asked, “What’s going on?”
The police told me to go inside
A SWAT member said, “Ma’am, A South American gang is targeting homes to steal from. The cell phone jammer says you might have been next. Do we have permission to enter your property?” I said, “Yes!” and then he asked something like, “If we find anyone, will you pursue charges so we can arrest them?” I replied, “Of course!”
I opened the driveway gates to our property and the guest house while Barry tossed the police keys to open the security gates. It turns out that when the gang saw we were home, they likely diverted their attention to the house next door. A house four doors down from us wasn't so lucky.
The homeowner left at 5 p.m. to have dinner and got a notification his security cameras were offline at 5:05 pm. He thought the internet went down. The gang broke in and took $25,000 in cash and valuables worth $100,000. They were in and out in less than 10 minutes.
How are they getting away with this?
The gang places cellular and wifi jammer around the homes they’re targeting. This way, security cameras and phones are useless. A Phoenix police officer told me the gang probably noticed nothing was down in our house.
Our home’s security cameras and internet are hard-wired. Even when the thieves tried to jam the Wi-Fi signals, the security camera’s red lights showed they were recording everything. We also still have a landline.
But how frightening is that? Your phone doesn't work. Your cameras aren't recording anything. On the upside, the gang doesn't carry guns. If they get caught, they'll spend about six months in jail before being extradited to Chile.
If you’d like to watch the action captured by my security cameras, I showed them during a Kim Komando Today video stream. I am so thankful for our police force.
Nothing is random
The gang thoroughly scopes out homes beforehand. They drive the neighborhood and look up homes on real estate sites to get an idea of where the primary bedroom is located. They look for dogs, too.
It’s not only a problem in Phoenix. This is happening all over the country. A friend was robbed by a similar gang in a guard-gated community in California. Kudos to Phoenix Police – they arrested three members of the gang who were in my neighborhood that night.
