Inspection Overview
The REDLINE DEFENSE inspection is conducted in two distinct phases to maximize detection while minimizing the risk of alerting any eavesdropper. A thorough inspection is recommended for locations identified as key areas. It is suggested to utilize invisible ink to mark essential items — streamlining follow-up inspections by eliminating the need to re-inspect items that remain unopened, thereby optimizing both time and cost efficiency.

TSCM Equipment
// Detection
Wireless Video Camera Detector
Handheld device used to detect any video transmissions from hidden wireless surveillance cameras within its frequency range.
// Spectrum Analysis
OSCOR Green Spectrum Analyzer
Designed for commercial TSCM operations — detects illicit eavesdropping signals, conducts RF emissions analysis, and supports site surveys across a 10 kHz to 24 GHz frequency range.
// Thermal
Portable Thermal Imaging Camera
Used to detect heat signatures from hidden circuits within devices like keyboards, mice, and electrical sockets — without requiring disassembly.
// NLJD
ORION NJE-4000
Non-Linear Junction Detector — detects active and inactive electronic components (diodes, transistors) in hidden devices using non-linear junction detection technology.
// Signal Detection
Acoustic RF Signal Detector
Acoustic detector for analog & digital RF signals including WiFi, Bluetooth, Spread Spectrum, Cellular 2G/GSM/PCS, 2.5G GPRS, 3G WCDMA/HSPA, and 4G LTE.
// EMF
Multi-Field EM Spectrum Detector
Handheld device for detecting EMF, ELF, RF (up to 10GHz) including 5G, smart meters, and WiFi — with integrated 2.5GHz spectrum analysis.
// Line Analysis
DPA-7000 TALAN
Telephone and Line Analyzer — detects eavesdropping devices on analogue or digital telephone lines with built-in Frequency Domain Reflectometer (FDR) to measure cable lengths, detect unauthorized junctions, and identify all telephone pair combinations.
// Counter-Surveillance
CPM-700 Counter-Surveillance Monitor
Detects and locates room, phone, body bugs, video transmitters, and tape recorders. Accessories include: Standard RF Probe, VLF Carrier Current Probe, Infrared Probe, RF Sniffer, Modular Phone Adapter, Acoustic Leakage Probe, and Broadband Microwave Probe.
// Acoustic Masking
ANG-2200 Acoustic Noise Generator
Generates perimeter noise to block wired/contact mics, audio transmitters in outlets, and laser/microwave window surveillance. Injects noise into the perimeter — not the conversation space — allowing natural conversation without interference. Customizable with transducers, speakers, and mounts.
