Wireless security cameras have become a popular choice for homes and businesses across the world, offering easy installation, remote monitoring, and integration with other smart systems. But with the increase of convenience comes new questions that have to be asked, and one of most common being: “Can wireless security cameras be jammed?”
In short, the answer is: Yes, they can be jammed. However, it is not as simple or common as people think. In this guide, the team at Tesla Security who one of Sydney’s most trusted security system installation providers, will walk you through how jamming works and how to prevent it.
Signal jamming in security cameras is a method used to disrupt the wireless communications between the security systems. Jamming involves the used of radio frequency interference to block the signal between your camera and its receiver, base station, or even cloud server.
While not a widespread threat in residential and commercial areas, jamming is a known tactic in planned break-ins, particularly in high-value targets or commercial settings. That’s why understanding this risk is important for anyone using wireless security cameras (and don’t want them to be jammed), and picking a good security camera is important as well!
So, can security cameras be jammed easily? Here’s what you need to know”
Most modern wireless cameras, specifically from brands like Hikvision, Dahua, and Bosch, use encrypted Wi-Fi or proprietary RF protocols, which are more difficult to interfere with.
For a security camera to be jammed, someone needs a signal jammer device which can emit noise on the same frequency as your security camera (typically 2.4GHz or 5GHz). These devices are illegal to own and use in Australia under the Radiocommunications Act 1992.
Many newer wireless cameras will notify users if they lose connection, meaning even if jamming occurs, it’s likely you’ll know something is wrong.
Choose professional-grade wireless security cameras with AES encryption and secure data channels. Brands like Hikvision and Dahua, which we install across Sydney, come with strong anti-interference features.
Select systems that send some form of notifications to you if a camera disconnects. This can alert you to suspicious signal drops or tampering.
If your cloud connection is jammed, local storage (such as simple SD cards or NVR systems) will continue recording, enabling your security camera system to keep working even though it has technically been jammed.
While 2.4GHz is more common, the 5GHz band is less crowded and harder to jam due to shorter range and different interference characteristics.
Integrating your cameras with a 24/7 back-to-base monitored alarm system ensures that even if cameras are disrupted, your alarm remains active and can still alert emergency responders.
While wireless security cameras offer unmatched convenience, wired cameras are immune to being jammed by radio frequency hacking because they transmit data over physical cables.
At Tesla Security, we specialise in the installation and configuration of both wired and wireless camera systems. A hybrid setup is getting more popular where combining wired cameras for critical zones and wireless for flexibility is shown to maximise coverage and reliability.
At Tesla Security, we specialise in designing and installing secure, jamming-resistant wireless and wire security camera systems for homes and businesses.
Our process is simple and effective, and has worked for the locals of Sydney with stopping their security cameras from being jammed for over 21 years. Our process is:
