The use of WiFi jammer by burglars to disable smart security systems has raised alarms from Los Angeles, claiming that the illegal devices, costing around $200 to $2,000, jam wireless signals and leaves cameras and alarms vulnerable to failure.
Homeowners are increasingly worried about home network security threats, but the issue is not so simple. The success of smart home security devices like video doorbells, smart lights, and wireless locks has made homeowners more reliant on connected tech.
Police are only saying burglars could be using wifi jammer, not that they’ve caught any in the act. There have been few isolated cases, like a 2023 Connecticut burglary, that have verified the use of such devices, according to CNET.

Smart Home Security Jamming Risks
If you think jamming a system is easy, then you’re mistaken. To be effective, criminals must investigate the exact frequency of a home’s devices, be in very close physical range, and use specialized black-market equipment.
Even if that is so, most security jamming risks are rendered doubtful by encryption or jamming signals detection software. Companies like SimpliSafe alert users on smartphone if interference is detected.
Motion-activated video doorbells are also difficult to jam. They activate faster than most jamming signals of alarm systems, often recording video before any jamming. Large jammers that could obscure larger areas risk cutting off neighbors’ devices, attracting them instead of preventing attention.
In fact, statistics reveal most robberies occur in much more direct manners. The FBI says burglaries account for only 16% of property crime, with many requiring no more than an open door or shattered window. The Council on Criminal Justice states that home break-ins decreased 19% early in 2025 from a year ago, and almost 50% since 2019.
Prevent Wireless Security System Hacks
There are practical ways to limit risks:
- Prevent wireless security system hacks with hard-wired systems, which cannot be jammed.
- Cellular backup security systems to strengthen the layer of protection if Wi-Fi fails.
- Power over Ethernet (PoE) cameras offer reliability without relying on wireless signals.
- Advanced systems feature devices with jamming detection, alerting users immediately to interference.
- Protocols like ZigBee operate on different frequencies, reducing smart home security jamming risks.
- Constant firmware patches and strong encryption minimize the risk of potential attacks.
Even tools such as the Flipper Zero linked with hacking are rarely effective against modern systems. Burglars prefer easy targets over high-tech attacks. Visible cameras, motion-triggered lights, and simply locking doors remain the most reliable defenses.
The reality is that WiFi jammers illegal and using them is considered a Wifi jammer illegal practice, making them a risky and ineffective tool.
At the end of the day, the anti-wifi jammer technology, combined with good habits and
cellular backup security systems, keeps homeowners far safer than any dramatic headline might suggest.
