Yes. Audits and factory visits are arranged through the sales contact published on this site.

What is your export experience?

We began exporting in 2025. Our export share is below 10% of revenue, and the main market is domestic (TÜV Rheinland, June 2026).

What does the TÜV audit actually verify?

It verifies that the company exists and is registered, that it has real R&D and manufacturing capability, that its quality management system is effective, and that it holds a valid import/export licence. It is not a product-legality determination and not an export authorisation.

Remote ID–First Drone Detection for Prisons: Compliance-Driven Situational Awareness Through Multi-Sensor Fusion

Remote ID–First Drone Detection for Prisons: Compliance-Driven Situational Awareness Through Multi‑Sensor Fusion

Prisons face a uniquely demanding low-altitude security challenge. A small drone can cross a perimeter quickly, operate at low altitude, and enable contraband drops, reconnaissance, or coordination attempts—often with little warning. In this environment, effective counter-UAS is not about “seeing an object in the sky.” It is about reconstructing intent and identity from signals—time, motion, radio emissions, digital identifiers, and visual/thermal cues—then turning that information into actionable decisions.
At Longwave (www.longwavecn.com), we emphasize a Remote ID–centric and compliance‑aligned detection approach designed for correctional environments, supported by complementary sensing and correlation to improve confidence, continuity, and operator clarity.

1) Why “Detection” Is Not Just Seeing

A drone is a small, fast, and often visually ambiguous target. Real security outcomes depend on answering practical questions:
  • Is it a drone or clutter (birds, vehicles, moving foliage)?
  • Where is it now, where is it going, and how fast?
  • Is it broadcasting a compliant identity (Remote ID), and what does that identity say?
  • Is it connected to a control/video link indicating active operation?
  • Can we confirm and track it consistently enough to support response procedures?
No single sensor answers all of these in every condition. That is why modern prison-grade drone detection increasingly relies on multi-sensor correlation, with Remote ID playing a central role for compliant identification and reporting.

2) Radar: Measuring Time and Motion to Reconstruct a Track

Radar is often misunderstood as “a camera that sees with radio waves.” In reality, radar interprets echoes and uses physics to infer target behavior:
  • Rangetime delay
  • Velocity and motionDoppler frequency shift
  • Signal conditioning and processing (filtering, amplification, integration, SNR thresholds) help separate weak targets from background noise.
  • Outputs can support azimuth/elevation
For prisons, radar is valuable because it can contribute continuous tracking and early awareness, particularly when visibility is poor or when visual identification is difficult.

3) RF (Radio Frequency): Drones Can Hide Visually—But Not Silently in Spectrum

Many drones rely on radio links for command/control and video transmission. Even when a drone is hard to spot, its emissions can reveal its presence and behavior. RF analysis can characterize signals by:
  • Frequency band activity (commonly in ranges associated with control and video links)
  • Bandwidth, power, waveform/modulation features
  • Timing and signal “fingerprints” that suggest active operation
In prison environments, RF sensing helps identify active links and can support tracking and investigative workflows when correlated with other detections.

4) Remote ID: Compliance-Driven Identification You Can Act On

Remote ID is the most direct path to answering “who/what is flying,” when compliant broadcast is present. Rather than inferring identity from behavior alone, Remote ID enables structured decoding of broadcast data that can include elements such as:
  • A unique identifier
  • Position, altitude, speed
  • Additional operational fields depending on protocol and implementation
A practical Remote ID workflow includes:
  1. Signal capture
  2. Protocol identification
  3. Decoding & information extraction
  4. Integrity/verification checks
  5. Operator presentation

Why this matters for prisons

  • Compliance alignment:
  • Faster classification:
  • Structured reporting:
Longwave’s emphasis is on Remote ID detection that prioritizes compliance‑relevant outputs, giving prison operators clear identity/status signals whenever compliant broadcasts are available—while still leveraging other sensors for continuity and confidence.

5) EO/IR (Electro‑Optical / Infrared): Visual Confirmation Is a Process, Not a Snapshot

Seeing a drone is not the same as confirming it. EO/IR systems typically involve:
  • Image acquisition
  • Noise reduction and contrast enhancement
  • Feature extraction
  • AI‑assisted detection/classification (model families may include modern detectors and classical classifiers)
  • Multi‑frame tracking and association to maintain lock over time
For prison operations, EO/IR can provide confirmation and evidence‑quality context, especially when cued by radar/RF/Remote ID detections.

6) Multi‑Sensor Fusion: Turning Signals into Decisions

The most effective approach is a correlation engine that brings multiple “physical realities” into a single operational picture:
  • Radar contributes time/motion‑based tracks
  • RF reveals emissions and link behavior
  • Remote ID provides compliance‑aligned identity/status when present
  • EO/IR supports confirmation and classification
A typical fusion flow is:
Perception → Target focus → Correlation → Threat assessment → Decision logic → Operator workflow → Response
For prisons, the goal is not only detection—but consistent, explainable, and actionable situational awareness that fits security procedures.

Conclusion: A Remote ID–Centric Strategy for Prison-Grade Drone Security

Prisons require a security model that is fast, reliable, and operationally clear. A Remote ID–first, compliance‑driven detection capability—supported by radar, RF, and EO/IR correlation—helps answer the questions that matter most: identity (when compliant), location, track continuity, and confidence.
Longwave’s approach focuses on delivering practical detection outputs that align with compliance needs while maintaining the robustness of a multi‑sensor architecture suitable for high‑security correctional environments.
If you want, I can adapt this into a final “About/Capabilities” webpage format specifically for www.longwavecn.com (with sections like Use Cases, System Workflow, Benefits, Typical Deployment in Correctional Facilities, FAQ), but I’ll need any preferred product name(s) and whether you want a stronger “solution marketing” tone or a more technical tone.
