A Wi-Fi jammer sends out a strong signal that can block wireless cameras from connecting. Jammers are illegal in the US. Experts in this story say the fix is a hard-wired camera system, which does not use Wi-Fi at all.
A viral video showcasing porch pirates using a Wi-Fi jammer to interfere with doorbell cameras in Texas has caught the attention of cybersecurity experts, who are now sharing tips to help protect homes and holiday packages from similar crimes.
Horacio Maysonet, CEO of Cyber Security Solutions, explained how Wi-Fi jammers work and why they are effective against wireless home security systems. "It’s an antenna that broadcasts a stronger signal than what your router antenna will be broadcasting, essentially blocking all the channels and creating a lot of noise. So the other antennas that are intended to connect and pass data can now no longer connect and pass data", Maysonet said. He compared this interference to a conversation being drowned out: "You can imagine if somebody’s screaming louder than you’re talking and you can no longer hear the person in front of you having a conversation."
Wired systems offer a solution
Maysonet emphasized that the best way to defend against signal jamming is to avoid relying on Wi-Fi-dependent devices altogether. "The only way to stop thieves from jamming your signals is to not use Wi-Fi", he said. A hard-wired surveillance system, which does not rely on Wi-Fi, eliminates vulnerability to jamming devices.
Wi-Fi jammers, though illegal in the United States, remain accessible. According to Maysonet, some devices marketed as RF detectors or hidden-camera sweepers can be switched into "active" mode to jam signals. "The moment any device is capable of transmitting interference, it becomes illegal to possess or operate in the United States under FCC regulations", he noted.
The Federal Communications Commission (FCC) reinforces this, stating on its website: "The use or marketing of a jammer in the United States may subject you to substantial monetary penalties, seizure of the unlawful equipment, and criminal sanctions including imprisonment."

Law enforcement reports mixed responses
Law enforcement agencies in Lake, Orange, Osceola, Seminole, and Volusia counties were contacted regarding reports of criminals using Wi-Fi jammers. While most agencies confirmed they had received no reports of such incidents, the Orange County Sheriff’s Office and the Orlando Police Department did not respond to inquiries.
As porch piracy continues to evolve with new methods of bypassing security systems, experts recommend exploring hard-wired alternatives to protect homes and packages. With the holiday season in full swing, keeping one step ahead of tech-savvy thieves is more important than ever.
What does this mean for your home?
If your doorbell camera runs on Wi-Fi, a strong outside signal could block it. A wired doorbell or camera keeps working because it does not use Wi-Fi. If you can, wire the cameras that matter most, like the front door. Most police agencies in this story had no reports of it happening.

We were surprised with what (Ryan) took away from the conversation – even reading between the lines to put everything we wanted and needed right into his designs for us. At first, we really didn’t know who to go with; we hadn’t had any renovations to our home before. We set up a consultation and liked (Ryan) because he was personable, a good listener and knowledgeable. He asked about our wish list and gave us some ideas…which were great.
– Mr. & Mrs. Caywood (1 Sound Choice client testimonials)
Truly One Sound Choice, you won’t find better. I called a couple of AV companies for quotes but on speaking with Ryan I had confidence that One Sound Choice would do the job right. Most companises had assured me that they would not have to cut holes in my walls to achieve my project goals. Ryan was up front, honest and realistic outlining all the possible challenges my install might face whilst reassuring me that One Sound Choice had the capabilitiy and expertise to meet my goals. Consulation was painless and Ryan and Kenny captured my requirements perfectly and offered advice based on their experience regarding optional additons to the project, which were practical and delivered exceptional enhancements. Ryan provided me with a view of what could be achieved given my requirements and then worked with me complete the project with consideration to my budget, but without compromising the final solution. Even completed the project without requiring any patch work which was a bonus. Ryan and Kenny were a pleasure to work with, respectful and courteous and I had confidence having them in our home. Highly recommend for any AV work you are considering. You will not be disappointed with the results.
