Wat is de Delta-S Wideband Detector precies?

De Delta-S Wideband Detector van Digiscan Labs is een professioneel counter-surveillance sweeping system voor het opsporen van RF-afluisterapparatuur. Het systeem scant het frequentiebereik van 57 tot 6000 MHz en detecteert zowel analoge als digitale zenders, continu en pulserend, met of zonder encryptie.

Welke signalen en apparaten kan de Delta-S detecteren?

De Delta-S kan een breed scala aan signalen detecteren, zoals GSM, 3G, 4G / LTE, 5G, Wi-Fi (2,4 en 5 GHz), Bluetooth, DECT en andere ISM-banden. Hierdoor kunnen onder meer GPS-trackers, RF-bugs, draadloze microfoons, verborgen camera’s met zender, smartphones en andere draadloze apparaten worden opgespoord.

Heb ik een laptop of tablet nodig om de Delta-S te gebruiken?

Ja, de Delta-S is ontworpen om samen te werken met een laptop of tablet. De hoofdunit wordt via USB aangesloten en haalt hier zowel de voeding als data-overdracht uit. De visualisatie, logging en analyse verlopen volledig via de meegeleverde Windows-software.

Wat is het voordeel ten opzichte van een eenvoudige bug detector?

Een eenvoudige bug detector geeft meestal alleen een basisindicatie van RF-activiteit. De Delta-S biedt daarentegen uitgebreide spectrumanalyse, waterfall-weergave, logfunctie en verschillende zoekmodi, waardoor verdachte signalen beter zijn te isoleren, te volgen en te rapporteren.

Kan de Delta-S ook 5G, Wi-Fi en Bluetooth detecteren?

Ja, de Delta-S ondersteunt moderne draadloze standaarden zoals 5G, Wi-Fi 2,4 GHz en 5 GHz en diverse Bluetooth-protocollen. Deze signalen vallen binnen het frequentiebereik van 57 tot 6000 MHz en kunnen via specifieke zoekprofielen worden geanalyseerd.

Hoe werkt de logfunctie in de praktijk?

De Delta-S slaat tijdens een sweep gegevens over gedetecteerde signalen op, zoals tijdstip, band, signaalsterkte en duur. In de software kunnen deze logs als lijsten of grafieken worden bekeken en kunnen verschillende sessies worden vergeleken om patronen in RF-activiteit te herkennen.

Is de Delta-S geschikt voor langdurig professioneel gebruik?

Ja, de Delta-S is ontwikkeld voor intensief professioneel gebruik. De robuuste behuizing, uitgebreide antenneset en gespecialiseerde software maken het systeem geschikt voor langdurige TSCM-onderzoeken en continue monitoring, zeker in combinatie met een laptop op netstroom.

The Digiscan Labs Delta-S Wideband Detector is a professional wireless activity monitor for TSCM (Technical Surveillance Counter Measures) investigations. This high-end system is designed to quickly and reliably detect hidden transmitters, eavesdropping devices, GPS tracking devices, and other RF sources within a frequency range of 57 to 6000 MHz. With support for 2G/3G/4G/5G, Wi-Fi, Bluetooth, and other wireless protocols, the Delta-S is a comprehensive counter-surveillance sweeping system for security professionals.

Unlike simple "bug detectors," the Delta-S combines a wideband RF detector with advanced spectrum analysis and logging. This allows you to determine not only that activity is occurring, but also which band is being used, how strong the signal is, how long it lasts, and whether it matches legitimate or suspicious transmitters in the area.

Professional wideband RF detection for TSCM

The Delta-S Wideband Detector continuously scans the spectrum from 57 to 6000 MHz with a sweep rate of 8 GHz per second. The system is specifically designed for professional use, such as TSCM inspections, securing boardrooms and meeting rooms, protecting critical infrastructure, and detecting eavesdropping devices on high-risk individuals. Thanks to its high sensitivity and wide dynamic range, both strong and very weak signals can be analyzed.

Detection of GSM, 3G, 4G, 5G, Wi-Fi, Bluetooth and GPS trackers

The Delta-S is capable of detecting modern digital and analog transmitters, including devices using mobile networks and ISM bands. The system can be used for, among other things:

Detect RF eavesdropping devices with SIM card (GSM, 3G, 4G/LTE, 5G)
To locate GPS beacons and vehicle trackers
Detect wireless microphones and classic FM/VHF/UHF transmitters
Wi-Fi 2.4 GHz and 5 GHz cameras and IP devices to detect
Analyze Bluetooth and other short-range connections

The combination of a wide frequency range and targeted search modes allows you to search specifically for suspicious transmissions in, for example, vehicles, offices, hotel rooms or sensitive meeting locations.

Logging function and advanced analysis

The Delta-S wireless activity monitor features a comprehensive logging function that clearly records signal type, signal strength, and signal duration. This log can be viewed and analyzed directly on a connected laptop or tablet. Different time periods can be overlaid to reveal patterns in RF activity, such as recurring bursts from a GPS tracker or brief connections from a hidden transmitter.

The software also supports advanced displays such as level indicators, spectrum + waterfall, and alarm overviews. This allows you to isolate suspicious signals from background noise and legitimate sources, making it easier to work your way back to the source of the signal step by step.

Operation with laptop or tablet

The Delta-S is designed as a portable main unit that connects to a laptop or tablet via USB. Power is supplied via the USB port, eliminating the need for a separate power adapter. In practice, this means battery life depends on the battery life of the laptop or tablet being used. When powered by AC power, the Delta-S can operate indefinitely, making it ideal for extended measurement and logging sessions in data centers, meeting rooms, or test setups.

Frequently Asked Questions about the Delta-S Wideband Detector

What exactly is the Delta-S Wideband Detector?

The Digiscan Labs Delta-S Wideband Detector is a professional counter-surveillance sweeping system for detecting RF eavesdropping devices. The system scans the frequency range from 57 to 6000 MHz and detects both analog and digital transmitters, both continuous and pulsed, with or without encryption. This makes it a powerful tool for TSCM specialists, security companies, and government agencies.

Which signals and devices can the Delta-S detect?

The Delta-S can detect a wide range of signals, including GSM, 3G, 4G/LTE, 5G, Wi-Fi (2.4 and 5 GHz), Bluetooth, DECT, and other ISM bands. In practice, this means you can locate GPS trackers, RF bugs, wireless microphones, hidden cameras with transmitters, smartphones, and other wireless devices. Thanks to targeted search modes, you can specifically target mobile/GPS trackers or Wi-Fi activity, for example.

Do I need a laptop or tablet to use the Delta-S?

Yes, the Delta-S is designed to work with a laptop or tablet running the included software. The main unit connects via USB and draws both data transfer and power from it. The device cannot be used without a computer, as all visualization, logging, and analysis are handled by the software. For professional use, a stable Windows laptop is recommended.

What is the advantage over a simple “bug detector”?

Simple bug detectors often only provide a beep or LED indication of RF activity, without distinguishing between legitimate and suspicious signals. The Delta-S, on the other hand, offers a full spectrum analysis with a waterfall display, logging, and various search profiles. This allows you to identify signals, locate them over time, compare them with the RF background profile, and pinpoint the source. This makes the Delta-S much more suitable for serious TSCM investigations.

Can the Delta-S also detect 5G, Wi-Fi and Bluetooth?

Yes, the Delta-S supports modern wireless standards such as 5G, Wi-Fi 2.4 GHz and 5 GHz, and various Bluetooth protocols. These signals fall within the frequency range of 57 to 6000 MHz and can be analyzed individually thanks to specific search modes. This makes it easier to identify, for example, a hidden Wi-Fi camera or a Bluetooth bug among other wireless sources.

How does the logging function work in practice?

During a sweep, the Delta-S stores key parameters of detected signals, such as time, band, signal strength, and duration. In the software, you can view these logs as a list or graph and compare different sessions. This is ideal for identifying periodic or short-lived transmissions, such as GPS position updates or data bursts from a hidden transmitter. The logging function also simplifies reporting and aftercare for the client.

Is the Delta-S suitable for long-term professional use?

Yes, the Delta-S is specifically designed for intensive professional use. The housing is robust, the antenna array is optimized for the full operating range, and the software is designed for long-term measurements and analysis. When used with a laptop powered by AC power, the system can provide continuous monitoring, for example, during multi-day security deployments, conferences, or investigations in critical environments.
