Physical, Electronic & Aerial Surveillance

Integrated ground, signal and aerial intelligence — giving you a 360° view of human and digital behaviour.

Most surveillance services stop at what they can see. But in today’s world, much of human behaviour is mediated through devices, signals, and even the airspace above us.

CDEC’s Physical, Electronic & Aerial Surveillance merges traditional covert observation with targeted, legally compliant electronic and drone-based reconnaissance. We currently operate fixed-wing light aircraft capability in the UK, with expansion to additional regions underway.

Alongside traditional foot and mobile teams, we use wireless reconnaissance tools, RF mapping, and aerial surveillance platforms to build a multidimensional picture of movements, habits and interactions.

By integrating ground, digital and aerial intelligence, we uncover relationships and patterns that would otherwise remain hidden — helping our clients see the unseen.

This capability integrates seamlessly with our Technical Surveillance Countermeasures (TSCM), OSINT Investigations and Threat Intelligence & Resilience programmes — ensuring intelligence collected in the field supports wider digital and operational objectives.

What Makes Us Different

• Beyond Line of Sight
  We don’t just watch from the ground — our teams operate across the physical, electronic and aerial spectrum to capture activity others miss.

• Multi-Vector Collection
  Ground observers, RF analysts and drone pilots work in synchrony to correlate human actions, devices and environments, building a verified intelligence picture.

• Real-Time Validation
  Electronic tools, RF sensors and drone footage provide time-stamped verification of physical activity, strengthening evidentiary confidence.

• Legally Sound and Discreet
  Every deployment is lawful, proportionate and compliant with UK surveillance, data protection and aviation regulations — preserving admissibility and client discretion.

Enhanced Capabilities

In addition to traditional surveillance, we can:

• Perform Wi-Fi and Bluetooth surveys to identify and track nearby devices over time.

• Capture unique device identifiers (MAC addresses, BLE beacons) for pattern-of-life analysis.

• Map the RF environment to detect unusual emissions, rogue access points, or the presence of GPS jammers.

• Use RF anomaly detection hardware developed under our Custom Security Solutions programme.

• Monitor for signals from GPS jammers and rogue hotspots, integrating findings with our Digital Forensics & Data Recovery team for deeper analysis.

• Employ OSINT investigations to cross-reference social media posts, geolocation data, and event check-ins.

• Deploy drones (where legally permitted) to:

  • Observe large or restricted areas from above.

  • Track foot or vehicle movements discreetly.

  • Inspect rooftops, compounds, and perimeters invisible from ground level.

  • Capture high-resolution imagery and video evidence for HR, legal or law-enforcement use.

Client Benefits

• Richer Intelligence
  Ground, electronic and aerial data fused into a single, validated intelligence product.

• Insight into Hidden Behaviours
  Identify device-switching, covert communications and off-grid meetings in complex or large environments.

• Future-Proof Surveillance
  Adapts to modern behaviour where digital footprints and airspace activity reveal more than visual tails.

• Higher Confidence in Findings
  Evidence corroborated across multiple independent collection vectors.

Engagement Options

• Verification of insider collusion or clandestine meetings.

• Monitoring of access to sensitive sites or protected individuals.

• Detection of hidden associates, vehicles or electronic devices.

• Mapping of patterns-of-life beyond visual range.

• Discreet observation of large, rural or industrial sites via aerial platforms.

• Building admissible evidentiary packages for HR, legal or law-enforcement partners.
