Private investigators (PIs) are skilled professionals who excel at gathering evidence, conducting interviews, and managing complex cases. But in today’s investigative landscape, many cases demand more than traditional methods. Technical surveillance—from covert cameras to tracker detection—has become a crucial part of modern investigations.

This is where the role of a Commercial Technical Support Unit (TSU), such as SIASS, becomes invaluable. By providing advanced technical surveillance capabilities, a TSU allows private investigators to expand their services, improve efficiency, and deliver stronger results for their clients.

Why Private Investigators Need Technical Surveillance Support

While private investigators are often generalists who handle a wide variety of cases, technical surveillance is a highly specialised field. Setting up and operating advanced surveillance equipment requires:

  • Expert knowledge of covert systems.

  • Specialist training to ensure lawful and discreet deployment.

  • Access to expensive, state-of-the-art surveillance tools.

For many independent PIs or smaller firms, investing in the latest technology and training is not practical. Partnering with a commercial TSU like SIASS bridges this gap.

What Is a Commercial TSU?

A Commercial Technical Support Unit (TSU) is essentially a team of technical surveillance professionals who provide covert surveillance support to investigators, businesses, councils, and individuals.

At SIASS, our experts—many of whom are former military specialists—deliver a full range of services, including:

  • Covert audio and video surveillance installation.

  • GPS tracker installation and detection.

  • Technical surveillance counter-measures (TSCM) bug sweeps.

  • Electronic monitoring and evidence gathering.

By acting as a technical partner, SIASS enables private investigators to focus on case strategy, client management, and intelligence gathering, while we handle the highly specialised surveillance side.

Benefits of Using a Commercial TSU

Working with a commercial TSU like SIASS offers several advantages:

1. Access to Cutting-Edge Equipment

PIs don’t need to invest thousands in covert cameras, trackers, or advanced counter-surveillance devices. SIASS provides access to this technology immediately.

2. Lawful, Professional Deployment

Surveillance law in the UK can be complex. Our experts ensure all equipment is used legally and proportionately, so evidence is admissible and investigations are compliant.

3. Efficiency and Focus

By outsourcing technical surveillance, investigators can dedicate more time to client relationships, interviews, and strategy while knowing the technical aspects are in expert hands.

4. Scalability

Whether a case requires a single covert device or a larger, multi-layered technical operation, SIASS can scale support as needed.

Safeguarding and Legal Considerations

Private investigators must always consider the legal and ethical implications of surveillance. Improper use of covert equipment can breach:

  • The Human Rights Act 1998 (right to privacy).

  • The Data Protection Act 2018 and GDPR.

  • The Regulation of Investigatory Powers Act 2000 (RIPA).

By working with a commercial TSU, PIs reduce their risk. SIASS ensures surveillance is conducted responsibly, safeguarding both investigators and their clients.

Why Choose SIASS as Your Technical Surveillance Partner?

At SIASS, we act as a trusted commercial technical support unit for private investigators across the UK. With specialist training, military-grade expertise, and access to advanced technology, we give investigators the tools they need to succeed—without the heavy investment.

Conclusion

For private investigators, technical surveillance can be the difference between an inconclusive investigation and a successful outcome. By partnering with a commercial TSU like SIASS, investigators gain access to advanced tools, specialist knowledge, and the reassurance that their operations are legally compliant.
