- Trusted in the field — relied on by investigators, law enforcement, and security teams.
Event Logging in Action
Most RF detectors lose data the moment you leave a site. The BH04 PRO stores a full history of threats internally. This lets you spot recurring RF signals over time, compare activity across locations, and make evidence-based decisions during ongoing investigations.
Built for Modern Investigators
- Developed from real-world TSCM feedback
- Simple, effective data presentation — no bloated software
- Integrates with other counter-surveillance gear (hidden camera detectors, GPS finders)
Independent Training & Review
The BH04 PRO is one of the few professional TSCM tools with a full-length, independent training video available online.
Veteran Private Investigator John Morris, with over 30 years of experience and founder of several TSCM companies, reviewed the BH04 PRO on his channel The PI Guy. In a 40-minute demonstration, he shows the device in real investigations and highlights its strengths:
- Live event logging in action
- Step-by-step professional sweep demonstration
- Clear verdict: “This is the only tool you need for 90% of TSCM sweeps. The other 10% are rare, high-level targets — like if the KGB or IRS are after you — and those cases require much more advanced technology.”
With over 5,600 views since June 2024, John Morris’ BH04 PRO video has helped onboard more than 100 TSCM professionals worldwide.

User Groups & Pro-Tips
TSCM Operatives
TSCM professionals need high-performance tools to detect unauthorized transmissions. The BH04 PRO’s event logging captures real-time data, documenting RF threats with precision. Its portable, discreet design enables easy deployment, while automated reporting ensures seamless monitoring. Covering 0.10 MHz to 8 GHz, it detects spy cameras, spycams, bugging devices, and listening devices, ensuring no signal is missed. TSCM operatives in government agencies, corporate security, and private investigations rely on BH04 PRO for actionable intelligence.
C-Suite Executives
Corporate leaders face corporate espionage and insider threats targeting sensitive discussions. The BH04 PRO secures offices, boardrooms, and residences, detecting unauthorized transmissions without requiring technical expertise. Financial institutions, legal firms, and technology enterprises benefit from proactive monitoring, preventing data leaks and unauthorized recording devices.
Security Consultants
Security consultants need fast, effective tools to assess vulnerabilities. The BH04 PRO detects and documents bugging, unauthorized devices, and surveillance risks with plug-and-play ease. Its automated reporting delivers professional-grade evidence, streamlining investigations. Law firms, private investigators, and security teams use it to monitor executive offices, conference rooms, and residences for covert surveillance threats.
Corporate Management Teams
Corporate security demands proactive threat detection. The BH04 PRO enables in-house teams to monitor high-risk areas, identifying vulnerabilities before exploitation. By tracking RF activity, security teams establish baselines and detect anomalies. Legal services, telecommunications, government agencies, and critical infrastructure face growing risks of spy cameras, listening devices, and rogue transmissions. BH04 PRO safeguards intellectual property, financial data, and sensitive communications, fortifying corporate security strategies.
IT & Cyber Security Teams
As cyber threats evolve, IT & Cyber Security Teams must address both digital and RF-based risks. The BH04 PRO bridges the gap between traditional network security and physical security by detecting unauthorized devices, rogue transmissions, and wireless eavesdropping attempts. Many cyber breaches originate from hardware-based attacks such as bugging, spycams, and listening devices hidden in secure environments. Data centers, financial institutions, and government agencies rely on the BH04 PRO to detect unauthorized wireless activity, ensuring that IT infrastructure remains secure against both digital and RF threats.
Event Logging - The Rise of Burst Signals
The Increasing Importance of Event Logging in TSCM Bug Sweeps
In today’s digital world, safeguarding sensitive information has never been more critical. Technical Surveillance Countermeasures (TSCM) bug sweeps play a vital role in detecting and neutralizing covert surveillance threats. However, traditional sweeps often fail to capture advanced digital surveillance tools, which remain inactive for long periods before transmitting data.
This is where event logging becomes essential, allowing professionals to continuously monitor for unauthorized transmissions and uncover threats that may otherwise go undetected.
Evolving Threat Landscape
The rapid rise of IoT-enabled surveillance tools with WiFi, GSM, and audio/video capture has changed the landscape of electronic threats. Traditional TSCM sweeps focused on physical inspections, but modern threats use burst transmissions, activating only for short periods to avoid detection.
Devices such as store-and-forward recorders capture hours of footage and transmit data at unpredictable times, making them nearly impossible to detect without event logging. Without continuous monitoring, organizations remain vulnerable to data leaks and corporate espionage.
Why Event Logging is Often Overlooked
- High Cost – Traditional event logging systems range from $7,000 to $25,000, making them inaccessible to many professionals.
- Security Concerns – TSCM specialists are reluctant to leave high-value systems on-site, while clients hesitate to take responsibility for the equipment.
- Lack of Awareness – Many clients and professionals underestimate modern threats, assuming event logging is only necessary for high-risk scenarios.
BH04 PRO – A Game-Changer in Event Logging
- Affordable – Priced at under $2,000, it eliminates cost concerns associated with traditional systems.
- Compact & Discreet – The small form factor allows it to be easily deployed on-site without raising suspicion.
- Unmanned Deployment – Can be left on-site, continuously recording transmissions, reducing the need for specialists to remain on location.
- Scalable – Multiple units can be deployed across client locations, enhancing surveillance coverage without major financial risk.
Understanding Advanced Digital Threats
- Records audio/video data and stores it internally.
- Transmits collected data at irregular times to avoid detection.
- Uses long-life batteries to remain hidden for extended periods.
- Can be purchased worldwide, making them easy to acquire and difficult to trace.
Without event logging, these threats remain invisible, as traditional sweeps only capture real-time signals. By incorporating event logging, TSCM professionals can track patterns, identify burst transmissions, and detect unauthorized signals with precision.
How Surveillance Threats Penetrate Organizations
- Competitors – Rivals attempting to gain access to strategic business intelligence.
- Disgruntled Employees – Internal threats from those seeking to sabotage operations or leak sensitive information.
- Industrial Espionage – Foreign or domestic actors conducting covert surveillance for strategic or financial gain.
- Cybercriminals – Hackers using RF-based transmission tools to extract data without network breaches.
The Value of Event Logging
- Capture Digital Footprints – Event logs create a forensic trail, helping professionals reconstruct activities and identify security breaches.
- Enable Proactive Threat Detection – Instead of reacting to incidents, organizations can detect suspicious activity before a breach occurs.
- Ensure Compliance & Auditing – Many industries require continuous monitoring for regulatory and legal compliance.
- Support Investigations – Provides detailed logs that serve as evidence in forensic analysis and legal cases.
