It quickly identifies nearby BLE devices and alerts the user to potential tracking threats, making it an essential tool for detecting covert monitoring or stalking devices.
Why is RF spectrum analysis important in a bug sweep?
RF spectrum analysis is critical in bug sweeps because it helps identify radio frequency signals emitted by hidden devices like audio bugs, wireless cameras, and GPS trackers. Our spectrum analyzers, like the MESA® 2.0 and the OSCOR Green, scan the RF spectrum for unusual activity, helping to detect covert devices that are transmitting data or interference.
What is a Non-Linear Junction Detector (NLJD) and how is it used in bug sweeps?
A Non-Linear Junction Detector (NLJD) is a specialized tool used to detect electronic components, including hidden surveillance devices, by identifying the non-linear electrical signatures they emit. Unlike traditional RF spectrum analyzers, which detect transmitted signals, the NLJD locates the internal circuits of powered or unpowered devices, such as microphones, cameras, or GPS trackers, by analyzing the way they respond to a radio frequency pulse.
This tool is especially effective for detecting covert surveillance devices that might not be actively transmitting but still contain electronic circuits that can be detected by the NLJD. It’s an essential piece of equipment for thorough bug sweeps, especially in environments where hidden surveillance devices might be intentionally deactivated or dormant.
