System Overview

NOCTIS-V is a fixed focal length VNIR imaging system built for effective surveillance under low-light environmental conditions — without requiring any active illumination source. Covering the 400–1000 nm spectral band, NOCTIS-V captures both the visible colour spectrum and near-infrared wavelengths simultaneously on a single sensor.

Near-infrared extends sensitivity far beyond what the human eye or a standard colour camera can achieve at dusk, dawn or under artificial lighting conditions. Where a conventional RGB camera loses contrast and detail as ambient light falls, NOCTIS-V maintains clear, high-resolution imagery — passively, with no IR illuminator that could compromise operational security.

The system integrates lens, camera and GUI into a single operational unit — enabling fast deployment and straightforward operator control without complex multi-component configuration. Designed to withstand extreme environmental conditions with an integrated anti-fog mechanism for reliable performance in challenging field environments.

What NOCTIS-V Sees — and When

The 400–1000 nm spectral range spans the entire visible spectrum and extends into near-infrared. Where visible light alone fades, NIR sensitivity sustains scene detail — from the moment ambient light begins to fall through to conditions where only artificial or ambient NIR illumination is present.

How NOCTIS-V Delivers
Low-Light Imaging

VNIR imaging extends scene visibility beyond the limits of the human eye — without the operational compromise of active illumination.

400– 1000 nm

Step 01 · Spectral Capture

One Sensor.
Visible and NIR.
Simultaneously.

The NOCTIS-V sensor is sensitive across the full 400–1000 nm band. As ambient visible light diminishes at dusk or under overcast conditions, the system draws on the near-infrared portion of the spectrum to maintain scene detail and contrast — automatically, with no mode change.

Why NIR Makes the Difference
↗
NIR wavelengths (700–1000 nm) penetrate haze more effectively and are less affected by atmospheric scatter than visible light.
◎
Vegetation, materials and surfaces that appear uniform in visible light show distinct tonal contrast in near-infrared.
∞
Continuous 400–1000 nm coverage — no spectral gap, no mode switch, no second sensor required.

Range.

The low F-number lens is paired with a motorised iris that adapts exposure as ambient light levels change — from full daylight through dusk to starlight. No manual intervention at the lens, ever. The operator adjusts remotely via GUI.

Step 03 · Passive Operation

No Illuminator.
No Signature.
No Compromise.

Active IR illuminators extend night-vision range but emit radiation detectable by adversarial equipment — revealing position. NOCTIS-V operates entirely passively: moonlight, starlight and ambient artificial lighting provide the NIR energy the sensor requires. Nothing is emitted.

Capability Comparison

VNIR vs. Standard RGB — Why Near-Infrared Changes the Picture

A standard colour camera captures 400–700 nm. NOCTIS-V extends that range to 1000 nm — and the difference in operational performance is significant.

NOCTIS-V — VNIR 400–1000 nm
  • Effective imaging from daylight through to dusk and artificial lighting conditions
  • NIR sensitivity — vegetation, materials and surfaces distinguished beyond visual range
  • Better contrast through light haze and fog conditions vs visible-only
  • Passive operation — no active illuminator, no detectable IR emission
  • Single sensor — simultaneous colour and NIR, no switching
  • Motorised iris — adapts to the full day/night illumination cycle remotely
  • Limited in complete darkness without ambient NIR — LWIR recommended for total darkness
Standard RGB Camera — 400–700 nm
  • High-resolution colour imagery in daylight
  • Contrast and detail degrade rapidly at dusk
  • No NIR sensitivity — cannot exploit ambient near-infrared
  • Requires active IR illuminator for night operation
  • Active illuminator detectable by adversarial NV equipment
  • Reduced haze penetration vs NIR wavelengths
Deployment

Where NOCTIS-V Operates

Passive day-night VNIR imaging is suited to any fixed surveillance post where operational security rules out active illumination — and where consistent 24-hour image quality is required.

Fixed Perimeter & Observation Posts

Mast or tower-mounted surveillance systems where 24-hour coverage is required and illuminator deployment would compromise operational security or draw adversarial attention.

Passive 24/7 operationRemote iris control via GUI

Border & Perimeter Monitoring

Long-duration border observation where illuminator-free operation reduces cost, eliminates maintenance requirements and ensures no active signature is present on the monitored line.

Extended operationNo illuminator maintenance

Force Protection & FOB Surveillance

Forward operating base and camp perimeter coverage — covert passive imaging that does not reveal post location or alert adversaries to observation capability.

Low signature operationCovert surveillance

Critical Infrastructure Protection

Energy, transport and government site perimeter surveillance where continuous day-night monitoring is required without the visual intrusion or operating cost of active illuminators.
