Lornet Star 24S Nonlinear Junction Detector – Advanced Counter-Surveillance System

Professional Counter-Surveillance System – Lornet Star 24S

The Lornet Star 24S redefines what a professional counter-surveillance system can achieve. As a state-of-the-art nonlinear junction detector (NJD) and RF bug detection system , it uncovers both active and passive electronic implants—bug transmitters, hidden cameras, and clandestine listening devices—no matter how well they’re concealed.

Security consultants, corporate investigators, and law-enforcement teams trust this enterprise bug sweeper to secure boardrooms, executive suites, rental properties, and high-stakes government facilities. With industry-leading dual-harmonic detection , modular antenna flexibility, and an intuitive workflow, the Star 24S delivers uncompromising performance in a handheld, field-ready package.

Advanced Detection Technology

At the heart of the Star 24S lies its unrivaled dual-harmonic detection capability. By capturing both second- and third-harmonic reflections from semiconductor junctions, the system locates powered-down devices that evade traditional RF sweepers. Its pulse probing mode emits high-power bursts for long-range sweeps through walls and ceilings, while the continuous-wave (CW) mode provides a steady carrier for pinpoint accuracy in tight quarters.

Operators benefit from a crisp spectrum analyzer display that plots real-time graphs of harmonic peaks, turning complicated signal analysis into rapid, confident threat confirmation. This blend of harmonic intelligence and hybrid detection makes the Star 24S the benchmark for professional NJD equipment.

Seamless Frequency Management & Anti-Jamming

Complex electromagnetic environments—crowded data centers, urban conference halls, or industrial facilities—can sabotage lesser detectors. The Star 24S tackles interference head-on with its automatic channel search algorithm, scanning in fine 200 kHz, 2 MHz, or 13 MHz steps to lock onto the quietest frequency band.

If hostile signals attempt to overwhelm your sweep, built-in anti-jamming algorithms kick in, filtering out center-frequency noise and maintaining rock-solid performance. For ultimate control, manual power and sensitivity control let you fine-tune output strength over a 20 dB range or set receive sensitivity across five discrete levels. The result is a reliable, clutter-free RF bug detection system that stays on target, every time.

Ergonomic, Field-Ready Portability

Powerful detection shouldn’t compromise mobility. The Star 24S adopts a familiar “metal detector” form factor, slipping effortlessly into one hand while operating as your go-anywhere portable voice recorder —metaphorically speaking—for electronics. Its removable telescopic rod extends from 54 cm to 86 cm for under-desk, wall-cavity, and duct inspections, then collapses in seconds for transport.

Lightweight at just 0.8 kg (detector head) plus 0.2 kg (rod), it tucks neatly into a rugged carrying case alongside its modular antenna, fast-charge Li-Ion batteries, headphones, and charger. Glove-friendly switches, a bright LED bar graph, and a clear interface ensure you stay in command—even under low-light conditions.

Real-World Applications

From corporate security to tactical counter intelligence, the Star 24S excels wherever hidden electronics threaten confidentiality. Corporate teams rely on it for pre-meeting sweeps of boardrooms, R&D labs, and VIP suites, ensuring sensitive discussions remain private. Counterintelligence units deploy it in diplomatic facilities and safe houses to detect passive implants before high-value engagements.

Private investigation firms use its advanced NJD technology to validate client claims of unauthorized monitoring in homes, offices, and vehicles. Industrial and utility sectors harness its broad-spectrum coverage to uncover rogue sensors on critical infrastructure and control rooms. At large-scale events, rapid sweeps of backstage areas, VIP lounges, and portable structures safeguard speakers, performers, and high-ranking attendees. No matter the scenario, the Star 24S provides the decisive edge in professional counter-surveillance.

Tangible Benefits for Security Professionals

Adopting the Lornet Star24S transforms your security protocols from reactive to proactive. By detecting powered-down implants that slip past RF-only scanners, you close critical blind spots. Its modular antenna system offers seamless transitions between 800 MHz, 2400 MHz, and 3600 MHz bands, eliminating the need for multiple devices.

Automated tuning and harmonic analysis reduce operator fatigue and minimize false positives, shortening sweep times and boosting team productivity. Clear visual feedback via the integrated spectrum analyzer display accelerates decision-making, while intuitive controls keep your focus on securing assets rather than fiddling with settings. With expert on boarding and training included, your team swiftly masters advanced TSCM equipment and maintains peak performance as surveillance threats evolve.

Why the Star 24S Stands Out

In a market flooded with entry-level RF sweepers and gimmicky bug detectors, the Lornet Star 24S shines as true professional counter-surveillance hardware. It surpasses basic devices through its hybrid pulse & CW detection , dual-harmonic precision, and intelligent frequency management.

Unlike bulky rack-mounted systems, the Star24S delivers field-ready portability without sacrificing capability, fitting seamlessly into carry-on luggage for global deployments. Its modular, firmware-upgradeable design future-proofs your investment, allowing you to adapt as new surveillance technologies emerge. For organizations that accept nothing less than best-in-class performance, the Star24S is the definitive solution.
