The Non-Linear Junction Detector (NLJD) detects electronic
semi-conductor components in walls, floors, ceilings, fixtures,
furniture, containers, or other surfaces. The NLJD is made to
detect and locate hidden cameras, microphones, and other electronic
devices regardless of whether the surveillance device is radiating,
hard wired, or turned off.
Efficiency: shorter wavelength model does better at detecting modern,
surface-mounted circuitry in normal office environments
Usability: multiple alert methods are available with a line-of-sight antenna
mounted display to allow users to visualize target and display
Portability: lightweight design is under three pounds and no assembly is
required with an integrated telescoping pole
1.Digitally modulated transmit signal, correlated 2nd & 3rd
harmonic response, provide improved detection & minimize
interference. And identify the "false" nodes connected by metal and
2.Under the maximum power and maximum sensitivity mode, the range
of the detection simulator is at least 2m. The analog device
selects a diode with an ordinary random configuration (located in a
transparent seal). In the actual measurement, the equipment can
penetrate 0.12m thick concrete non load-bearing wall to detect the
3. Built-in high capacity rechargeable 29.4V/2200mA lithium battery
4.Power consumption is not more than 8W.
5.The self controlled power supply can be used for no less than 3
6.The operation buttons (except power switches) all are located on
the screen, which is more convenient for operation. The display is
a blue LCD screen, and its high brightness rear projection light
source can be used in normal daylight.
7.The weight include packing is less than 8kgs, the receiving
station is less than 2.5kgs,
And packing size is 83cm*33cm*29cm.
8.Limit temperature range:－15℃～45℃.
9.Relative air humidity: less than 80%, when the temperature is
