Glendale police issue warning about burglars using WiFi signal jammers to disable alarms, security cameras


GLENDALE, Calif. (KABC) -- Glendale police have issued a warning about residential burglars who use WIFI jammers to disable security alarms and surveillance cameras.


As described by police Sgt. Victor Jackson, the devices used by thieves block the signal or scramble the WiFi. "So if you have a Ring camera, a Nest camera -- any kind of alarm system that is WiFi-based or a camera that's WiFi-based -- it blocks the signal and knocks it out," he said.


A disproportionate surge in residential burglaries plagued Glendale and Southern California in the fall, leading investigators to the crime trend.


"As our detectives started going into these cases, that's when they realized what was happening," Jackson said. "In some cases, because of the way the device works, it made it look like when you went back and rewound your tape and looked, it wasn't a black screen -- it was seamless. It didn't exist there, so there was no evidence."


Police recommend that residents increase security by:



  • hardwiring alarm systems and cameras,

  • using back-up batteries in those security devices,

  • installing sturdy locks on security gates,

  • enhancing exterior lighting,

  • securing windows and balconies,

  • and having a trusted neighbor or housesitter look after your home, when away.

The Glendale Police Department's residential burglary task force has been working to lower the number of break-ins, officials said.


"Our patrol officers, our motor officers, our special enforcement detail, and detectives -- we have them undercover in the area -- and we saturated the area," Jackson said.


Nora Alabi, a Glendale resident, told ABC7: "I feel like there's no part of the city that you can be in and not run into a cop or not run into a police car.


"If I stand here for five minutes, I might see like three cop cars drive by," she said. "So, because of that, I feel like it's a safe city."

In a statement by the Los Angeles Police Department, officers warn that a group in Wilshire is using wifi jamming technology to disarm surveillance cameras and alarm systems that rely on Wi-Fi.


(TNS) — A group of thieves have been outsmarting smart devices across the Los Angeles area, authorities said.



8 Bands Jammer Device

In a March 4 statement by the Los Angeles Police Department, officers warn that a group in Wilshire is using Wi-Fi jamming technology to disarm surveillance cameras and alarm systems that rely on Wi-Fi.


This swarm of tech-savvy robberies in California is part of a larger “smart” crime wave happening nationwide. Last year, police in Minnesota and Connecticut issued similar warnings to residents when groups of Wi-Fi jamming thieves made their rounds. And those are just two examples of many.


While the Federal Communications Commission has banned Wi-Fi jamming devices, this doesn’t stop criminals from buying them cheaply, KARE11 reported. Wi-Fi jamming devices don’t necessarily deactivate devices, but work by overloading the network the devices are connected to.


“These (signal jamming) devices create traffic jams for the radio transmitter so that real traffic cannot get through,” cybersecurity expert Mark Lanterman told the outlet.


“If you are going to use a Wi-Fi camera for your front door, perhaps consider using a hardline camera inside your home,” he said. Wired cameras connected via Ethernet cables do not rely on Wi-Fi networks and would not be disrupted by a Wi-Fi jammer.


Los Angeles police also recommends hard wiring burglary alarm systems


While “smart” technology may be part of the problem, it may also have a hand in the solution, according to Tom’s Hardware. Officials recommend using timers or smart home devices to make it look like someone is home while you are away. Some smart home technology also comes with the ability to alert users if the signal or connection has been interrupted.


Tom’s Hardware also recommends connecting surveillance devices that store camera footage directly on your device, and not just to a cloud storage system. By having a camera that records to itself, you’ll have footage saved during a Wi-Fi disruption.


The LAPD also encourages people to stay vigilant by locking their doors, relying on neighbors to check on things when away and reporting any strange activity, including suspicious vehicles with temporary or dealer plates.

A word of caution has been issued by the Los Angeles Police Department to the residents regarding the utilization of WiFi jammers by criminals. These jammers are being employed to easily deactivate "connected" security cameras and sirens. It is important to be aware that these jammers can be purchased at low prices from platforms like Amazon.



Los Angeles news station KTLA5 has highlighted a concerning trend where tech-savvy thieves are utilizing WiFi jammers. These small devices have the ability to confuse wireless devices and inundate them with excessive traffic. By doing so, these criminals can gain access to homes without triggering any alarms. This raises questions about the vulnerability of affordable housing to security devices like Ring and Eufy.


According to a recent report by Tom's Hardware, instances of criminals employing WiFi jammers have been documented for quite some time. These jammers can be conveniently purchased online for a modest price of $40.


From a legal perspective in the United States, their use is considered illegal...



In a 2020 FCC alert, it was stated that the deliberate use of phone jammers, GPS blockers, or other signal jamming devices to block or interfere with authorized radio communications is considered a violation of federal law.


Despite the warnings, it appears that they were disregarded. Recently, law enforcement in Minnesota uncovered that nine robberies within a six-month period were linked to the use of wifi jammers. Luckily, the thieves are still opting for non-violent methods and focusing on empty houses.


In light of the current circumstances, the Los Angeles Police Department is suggesting that homeowners opt for hardwired alarm systems instead of relying solely on WiFi. Furthermore, they are urging residents to ensure their homes are well illuminated during the night.


The LAPD further suggests that you take precautions to keep your departure from your residence for an extended period of time confidential.


Cell phones serve as two-way radios that communicate via cell towers. cell phone jammer operate by emitting a strong signal on the same frequencies utilized by mobile devices, effectively blocking communication between the device and the cell tower. As a result, the mobile device loses connectivity and shows "No Network" on the display.


Cell phone jammers prevent and disable any mobile phone communications from entering specific areas of a building or open space to




  1. Take proactive steps to counter industrial espionage by implementing stringent measures to deter the use of mobile devices as eavesdropping tools or for unauthorized photography purposes.

  2. The endeavor to combat terrorist threats encompasses the mitigation of actions such as remotely triggering explosive devices in areas of heightened vulnerability.

  3. The eradication of public nuisances in establishments such as movie theaters, restaurants, and churches is essential.


This item is available in a range of sizes and shapes. You can find pocket-sized versions as well as larger ones. Moreover, some models are cleverly disguised 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

The rise of the Internet of Things has led to an increasing demand for location services. According to certain institutions, it is predicted that 60% of Internet of Things devices will rely on geographical location data. Outdoor positioning, in particular, is expected to be a significant market that should not be overlooked.


The GNSS (Global Navigation Satellite System) is a highly esteemed international club comprising of merely four members, which garners the interest of global leaders and the scrutiny of numerous esteemed scientists and engineers. These four members include the GPS of the United States, GALILEO Galileo of Europe, GLONASS of Russia, and Beidou COMPASS of China.


There are four prominent satellite navigation systems worldwide, including China's Beidou satellite navigation system, the United States Global Positioning System (GPS), the European Union's Galileo satellite system (GALILEO), and Russia's GLONASS satellite system (GLONASS). These four systems are acknowledged as suppliers by the United Nations Satellite Navigation Committee.


China Beidou is a recent addition, yet it stands out as the most dynamic member in terms of development. What exactly is Beidou and how does it influence our daily lives? This intriguing subject has garnered significant attention. Numerous scholarly publications delve into the intricacies of Beidou; however, these professional articles often employ jargon that may deter the interest of the general public.

Small GPS signal blockers great use


Utilized extensively worldwide, the GPS satellite positioning system is the most prevalent satellite positioning system. It facilitates vehicle tracking, route navigation, information inquiry, traffic command, emergency assistance, and other essential functions. Although the GPS satellite positioning system has greatly enhanced convenience in our daily lives, it has also introduced certain issues that can jeopardize individual safety.


To illustrate, in the case of a mortgage car company, they temporarily assume control of the car by providing financial assistance to the original owner. In order to prevent any covert retrieval of the vehicle by the original owner, these companies invest in GPS shields. These shields are installed both in the vehicle's parking lot and on the car itself, effectively preventing the original owner from locating the vehicle and thus ensuring the safety of the property.


As the GPS locator market expands, there is a growing interest in GPS signal blockers among those who wish to evade GPS signal tracking. However, it is crucial to ascertain whether the GPS signal blockers currently available in the market are capable of effectively shielding signal tracking.


Most GPS locators can be effectively shielded by gps blocker. The use of blockers disrupts the normal functioning of the GPS locator, preventing complete data transmission to the locator monitoring platform. Similar to mobile phones, GPS locators require the insertion of a mobile phone card or an Internet of Things card to retrieve data. Therefore, as long as the GPS signal blocker can obstruct the signal transmission of the mobile phone card, it can also block the GPS locator.
