"Short-wave infrared. Long focal length. Sees through what visible light cannot."
VANTAGE is a short-wave infrared motorised zoom lens system engineered for long-range surveillance and target identification in conditions where visible-band optics fail. Operating in the SWIR waveband (900–1700 nm), the system maintains high image clarity in low-light, haze, smoke, light fog and adverse weather — without requiring active illumination. The 450mm focal length delivers the standoff imaging range needed for perimeter, border and critical infrastructure surveillance from safe operational distances.
The low F-number optical design maximises the amount of SWIR radiation gathered at the sensor, ensuring superior sensitivity at the limits of visibility where competing systems saturate or lose contrast. High MTF (Modulation Transfer Function) values across the zoom range mean that spatial resolution is maintained at every focal setting — targets remain identifiable at range, not just detectable.
VANTAGE integrates lens, camera and Electronic Control Unit (ECU) into a single operational system. The motorised zoom mechanism allows the operator to transition from wide area search to close target identification without any physical adjustment to the lens — all controlled remotely through the integrated GUI or external command interface. The sun shield and vibration damper protect optical performance in the field. A second variant, the VANTAGE-M (180mm), offers a more compact configuration for platform-constrained installations requiring mid-range coverage.
SWIR wavelengths cut through haze, light fog and atmospheric scatter that defeat visible-band surveillance. At 450mm focal length, VANTAGE delivers identification-grade imagery at distances where standard EO systems can only detect a presence — and continues to operate effectively when ambient visible light falls below usable levels.
VANTAGE is available in two configurations — the 450mm primary variant for long-range standoff surveillance, and the VANTAGE-M 180mm compact variant for platform-constrained installations requiring shorter to mid-range coverage.
SWIR imaging exploits wavelengths that atmospheric particles scatter less than visible light — and that are reflected strongly by materials invisible to standard EO cameras. VANTAGE combines this physics with a 450mm motorised zoom to deliver actionable intelligence at range.
Short-wave infrared wavelengths (900–1700 nm) behave fundamentally differently to visible light in the atmosphere. Particles responsible for haze, smoke and light fog scatter shorter wavelengths aggressively — but SWIR passes through with significantly less attenuation. The result is contrast and detail at range in conditions that reduce visible-band cameras to near-useless imagery.
The 450mm focal length provides the angular resolution required to positively identify targets at the standoff distances demanded by perimeter, border and critical infrastructure surveillance. The low F-number optical design maximises the SWIR energy gathered at the InGaAs sensor — sustaining image quality as ambient light falls and atmospheric attenuation increases. High MTF values maintained across the zoom range ensure that spatial detail is preserved at all focal settings.
VANTAGE integrates the lens optical assembly, SWIR camera and Electronic Control Unit into a single delivered system. The motorised zoom, focus and iris are all remotely operated through the ECU — no physical access to the lens is required during operation. The integrated GUI interface allows the operator to manage all lens functions from the ground station or command post, including zoom positioning, iris adjustment and focus control.
At long range and in degraded visibility, the choice of imaging waveband determines whether surveillance is operationally useful or not. VANTAGE's SWIR capability delivers where visible and NIR systems reach their limit.
Long-range SWIR zoom imaging is required wherever surveillance must be maintained beyond the range of standard EO systems, or where atmospheric conditions — haze, smoke, light fog — routinely degrade visible-band performance.
Long-range identification of vehicles, vessels and personnel at border crossings and coastal approaches — in haze, fog and during dusk and dawn periods where visible-band systems lose effectiveness.
Extended-range perimeter surveillance covering ground approaches that lie beyond the effective range of shorter-focal-length EO systems — with passive night capability removing the need for active illuminators.
Surveillance of energy, transport and communications infrastructure where long standoff distances are required — monitoring approaches to sensitive sites from beyond the perimeter fence line.
Long-range SWIR imaging for vehicle and vessel classification at customs, port and border installations — delivering identification-grade imagery at distances and in conditions that defeat standard EO systems.
