_Non-Linear Junction Detector (NLJD)
The Non-Linear Junction Detector (NLJD) is a sophisticated piece of surveillance equipment used to detect hidden electronic devices that do not transmit signals. With its advanced technology, the NLJD can identify even the most covert listening devices, cameras, or other electronic components by emitting radio frequency signals and detecting non-linear electronic junctions.
## How Does an NLJD Work?
A Non-Linear Junction Detector illuminates an area with high-frequency RF energy.
Semiconductor junctions inside hidden electronics distort that signal and re-emit it on harmonic frequencies.
By listening for the **second and third harmonics**, an NLJD can distinguish true electronics from harmless metal objects, keeping false positives low.
