Break-in suspects using cell-jamming technology to avoid surveillance cameras

CMPD has revealed that burglars have found a way to outsmart surveillance cameras during specific home break-ins, employing technology in the process, according to WBTV.


When a person uses a device to interfere with radio or wireless signals, it is known as cell-jamming.


According to the Federal Communications Commission, deliberately utilizing a phone jammer, GPS blockers, or any other signal jamming device to disrupt authorized radio communications is considered a violation of federal law. It is important to emphasize that this prohibition applies universally and does not exempt usage within a business, classroom, residence, or vehicle.



Cell-jamming could potentially occur from a device roughly 30 feet away from the intended target, or home monitoring cameras.


A suspect was observed on video skulking through a yard in a south Charlotte community during the night. It is crucial to acknowledge that not all incidents have been recorded on camera.


The significance of safeguarding wireless devices from interference was underscored by John Shocknesse, VP of Customer Operations for CPI Security.


In a brief moment, an individual can be caught on camera, however, the implementation of cell-jamming technology permits their sudden disappearance with a simple flip of a switch or press of a button.


According to CMPD, this has been observed as a concern in several incidents of home break-ins in south Charlotte.


It was pointed out by Shocknesse that there has been no sign of that activity, underscoring the importance of awareness and having top-of-the-line technology.


WBTV inquired about the specific devices that are more susceptible to cell-jamming.


The observation made by Shocknesse suggests that the concern arises when dealing with older wireless devices that do not have encryption.


His statement highlighted the fact that current security and surveillance systems boast superior technology, including encryption, for enhanced security.


Emphasizing the necessity of cameras and onboard recording, Shocknesse mentioned the presence of memory devices to store footage for potential use by the police.


Moreover, he advised that the most effective solutions for preventing cell-jamming involve utilizing modern technology with encryption and opting for a wired device instead of Wi-Fi.


Simple yet effective ways to prevent home burglaries include keeping the area well-lit, activating alarm systems, and trimming bushes to a height not exceeding three feet.

Thieves are using Wi-Fi jammers to break into people’s homes

It has come to the attention of authorities that a group of thieves has been outsmarting smart devices in the Los Angeles vicinity.


The Los Angeles Police Department's statement on March 4 raised awareness about a group in Wilshire utilizing Wi-Fi jamming technology to disrupt surveillance cameras and alarm systems that depend on Wi-Fi connectivity.


The swarm of tech-savvy robberies taking place in California is a manifestation of a larger-scale "smart" crime wave that is unfolding across the entire country. Last year, police departments in Minnesota and Connecticut raised similar concerns, alerting residents to the presence of organized gangs specializing in Wi-Fi jamming. These instances represent only a fraction of the many occurrences observed.


signal jamming

As reported by KARE11, criminals can easily obtain Wi-Fi signal jammers jamming devices at a low price, despite their prohibition by the Federal Communications Commission. These devices do not deactivate other devices but instead overload the network they are connected to.


Mark Lanterman, a cybersecurity expert, stated that these devices are used to jam radio transmitters, leading to traffic jams that block authentic communication.



In his suggestion, if you decide to utilize a Wi-Fi camera for your front door, it might be advisable to consider using a hardline camera inside your home. Wired cameras connected via Ethernet cables do not depend on Wi-Fi networks and would not be affected by a wifi jammer.


Hard wiring burglary alarm systems is a recommendation made by the Los Angeles police.


As reported by Tom’s Hardware, smart technology might be involved in both the problem and the solution. Officials advise using timers or smart home devices to create the impression of someone being home while you are away. Additionally, some smart home technology can alert users if there is a disruption in the signal or connection.


Tom's Hardware also advises connecting surveillance devices directly to your device for storing camera footage, rather than solely relying on a cloud storage system. By doing so, you can ensure that the footage remains saved even during a Wi-Fi disruption.


Residents are encouraged by the LAPD to maintain awareness by securing their doors, requesting assistance from neighbors to monitor their property during periods of absence, and alerting authorities to any unusual activity, especially involving vehicles displaying temporary or dealer plates.


Wilshire Park is located in Central Los Angeles.

Technical classification of mobile phone signal inhibitors

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 university invigilator inspects for cheating during exams

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.

How criminals are using jammers deauthers to disrupt WiFi security cameras

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.

Thieves using cellular and Wi-Fi jammers to enter homes for robbery

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.

Can A Thief Really Jam Your Alarm System?

How to stop wifi jammer attacks on home security systems


The internet was abuzz with a viral news story from Queens, New York, which showcased a burglar effortlessly sliding across the floor while holding an enigmatic device. According to reports, this device was suspected to be a wifi jammer, strategically employed by the intruder to disable the home's wifi network and render the alarm system inoperable, allowing him to carry out his activities undetected.


Is this even possible? Yes, yes it is.


Hidden Camera Detectors

So what is a wifi jammer?


In essence, these jamming devices generate a frequency that disrupts the functioning of 3G, 4G, 5G, cordless, and wifi networks. Essentially, they affect all of these networks.


The presence of excessive noise disrupts the functioning of devices that rely on those frequencies for their normal operation. This interference extends to emergency networks used by first responders, which is the reason why the use of such devices is deemed illegal. However, these unauthorized devices are produced and traded on the black market, and individuals can potentially create their own. It is strongly recommended not to search for instructions online, as it may lead to being monitored by authorities.


Through the generation of disruptive noise, a signal blocker device disrupts the frequencies utilized by our devices, preventing their proper functioning. This interference extends beyond the intended targets, affecting a significant number of devices.


With this new information in mind, do you foresee any issues with your phones, alarm sensors, alarm base station, smart locks, and wifi cameras? It is a potential risk.


You might be wondering about this: "Andy, my alarm system has a cellular backup for when the wifi goes down. Will it still be functional?" Sadly, the answer is no. The sensors will be unable to establish communication with the base station due to the interference caused by these jammers. It is crucial to keep in mind that these jammers not only disrupt wifi signals but also block mobile spectrums, rendering your base station incapable of making calls over wifi or a cellular network.


How To Stop Wifi Jammer and Deauth Attacks


With knowledge about the nature and outcomes of these attacks, what steps should we take to defend against them? Have you remembered my caution about refraining from showcasing the alarm company branded sign in your yard?


This serves as an explanation as to why it is crucial to keep your home security methods confidential to avoid being targeted by criminals who could exploit your defenses. It is quite simple to identify companies that utilize the 2.4 GHz band.


When selecting new smart home products, ensure they are dual-band or compatible with the 5 gigahertz frequency. I've read about the potential benefits of WPA3 security in preventing these attacks, but as a novice, I cannot confirm its effectiveness. Regrettably, wireless alarm systems are still at risk of jammer attacks.


Select the old-fashioned route by installing a fully wired home alarm system that is connected to a landline. If there are no wireless components, then you should have no issues.


Local storage is a key feature in cameras provided by companies like Ring. This feature allows the cameras to continue recording clips even if there is a wifi outage or cloud storage is not accessible. While you may not receive notifications during such circumstances, you can still access the footage by simply checking the SD card inserted in the camera itself.


To ensure the reliability of your home security, it is recommended to consider adding a cost-effective local storage camera to your existing wifi camera system. By doing so, you can mitigate the risk of losing all footage in the event of a jammer or deauth attack. However, it is crucial to note that if the attackers identify the camera, they may try to vandalize it and take it along.

Wi-Fi jamming to knock out cameras suspected in nine Minnesota burglaries

According to the police, this technology has been utilized in a string of nine robberies in Edina.


In Edina, Minnesota, a serial burglar is suspected of employing a Wi-Fi jammer to incapacitate connected security cameras. This method allows the burglar to carry out thefts and escape with the valuable possessions of their victims.Minnesota is not commonly thought of as a technology hub, so it should come as no surprise that incidents involving Wi-Fi jammers aiding in burglaries in the U.S. have been reported for several years. This serves as a reminder that technology is being utilized by criminals, and an increasing number are recognizing its potential -- hence, homeowners should consider taking precautions.


The Edina police have raised suspicions that nine burglaries occurring in the previous six months might have utilized Wi-Fi jammers to prevent the acquisition of incriminating video evidence by investigators. It is believed that the perpetrators have a specific way of carrying out their crimes:



  • Dwellings are situated in affluent regions.

  • The houses are carefully surveilled by burglars.

  • The burglars steer away from confrontation, opting to wait until homes are unoccupied.

  • Seizing the chance of a vacant home, the perpetrators will employ Wi-Fi jamming technology.

  • Thieves often focus on stealing high-value designer items like safes, jewelry, and other luxury goods.

A security expert, interviewed by KARE11, shared valuable information regarding the nature of jammers. The expert clarified that signal jammer do not block signals but instead create confusion among wireless devices. By overwhelming wireless traffic, these devices effectively disrupt the flow of genuine data, as informed to the source publication.


handheld wifi signal Jammers

Jamming wireless security devices is a growing trend


Searching back through news reports concerning burglaries where wifi jammer have / may have been used surfaces plenty of prior evidence of this practice. A Ring community post about one of the firm’s wireless doorbells missing a porch thief after being subjected to a Wi-Fi deauthentication attack was posted back in January 2020. It is also easy to find reports of burglars using Wi-Fi jamming technology over 2021, 2022, and 2023 – with reports becoming more frequent over time.


Ring is highlighted as one of the companies that played a role in making video doorbells more mainstream to address a range of home security concerns, although other wireless smart home security products from Blink (Amazon) and Nest (Google) may also face vulnerabilities to wireless signal interference.


As we come to a close, we would like to offer a few recommendations to those who may be wondering about the effectiveness of their home security systems with wireless components. Firstly, consider establishing physical connections for certain devices that support wired connections and enable local storage of recorded footage. Secondly, make use of smart home technology that can create the illusion of occupancy. Additionally, your device may have the capability to send alerts in case of signal or connection interruptions, so it may be worth exploring and adjusting these settings.

Sounds like the Thieves Are Jamming Wifi and the Sensors

I read a few of the news articles and it sounds like the thieves are jamming WiFi and the sensors. This prevents the system from even triggering. The thieves are walking around the homes without the glass break, door, and motion sensors going off it seems.


Not commonplace, but getting some exposure in the news recently - gangs of organized thieves in metro Detroit area are targeting upper scale homes for burglaries. They are purportedly using wifi jammer to circumvent alarms (like Ring).


What can millions of Ring (and customers from other wifi-dependent alarm companies) do about this? IS there a viable counter to these signal jammer? Maybe it's time to explore legacy, analog wired alarm solutions as backup instead of the reverse?


They're using a wifi jammer, according to this article. No obvious way to prevent this, so hardwired systems would be the only resistant option.


Most Wi-Fi jammers use disassociation flooding to kick the devices off the network. This attack is prevented with WPA3 which can use protected management frames. Unfortunately Ring still hasn’t got around to adding WPA3 support to its devices. It was requested via their feature request process a long time ago, so I’m not overly hopeful they’ll add it.


There are trade offs and risks with each security system. There’s also different types of burglars from opportune amateurs to seasoned pros.


If you’re concerned about this threat, there’s a raft of solutions out there with high definition footage without any reliance on Wi-Fi or internet.


Whatever they're using for jamming must go beyond the WiFi frequencies to affect z-wave and whatever frequency Honeywell et al uses for their RF communications.


This makes sense because most alarm systems these days (even ADT/Brinx/etc) rely mostly on wireless sensors.


This is a huge vulnerability because it's pretty rare to find a security system that's been installed to use all hardwired sensors. To go hardwired you probably had to have it built-in as the house was built or did it while doing some major remodeling.


Cellular jammers are readily available. DSL, cable, or fiber are not jammable, but all devices need to be hardwired.


Zwave can be jammed just as easily as wifi. Cellular is great but if the door/window sensors are blocked and unable to report to the base station, the alarm won't think anything is wrong.


What I found when doing some simple research over the last couple of days is that different manufacturers use different frequencies for their devices so it might be a guessing game for the burglar, although my guess is that the professional burglars carry jammers for most of the common frequencies used by the big name brands like Ring, Simplisafe, Nest(ADT), etc.


To me it makes sense to have devices from different brands. Ring doorbell, ADT alarm, Wyze cameras, etc...


What's scary is that there are a bunch of videos on youtube demonstrating how easy it is to bypass these alarms AND with instructions telling you exactly how to do it and how to get the jammers.


Is this pervasive? If you watch the news, it’s pretty evident thieves aren’t concerned with cameras. They mask up and hood up and go. Be on alert, they have no fear.


Burglars can use wide-band jammers to jam all frequency bands : GSM, LTE, Wifi and Z-Wave. Some alarm systems are robust to such attacks (like Ajax Alarm System -- https://ajax.systems/blog/what-is-jamming/).


In short, the alarm hub must be hardwired with Ethernet to your router; And hub, router and modem on a battery backup. Then, only communications between sensors and hub can be jammed.


Then, alarm hub communicates frequently with sensors. If communication fails, it signals a jamming attack, notifying the user via hardwired Internet. With a working speaker on the hub, it can sound a siren and send a voice alert to the intruders.


SimpliSafe system is another system that offers some jamming protection, but lacks the Ethernet hardwired connection, so it must rely on a GSM/LTE link, which is still better than Wifi alone.
