The XHC2025C delivers 0.001 lux starlight colour imaging and 1910 m person detection via a 22.5 mm F1.2 lens, targeting the medium-range coverage gap in border observation and perimeter security networks.
Surveillance networks tasked with covering open terrain between 500 m and 2000 m face a persistent equipment gap. Short-range cameras saturate quickly once a patrol zone extends beyond a single checkpoint, while long-range sensors sized for 4000 m or more carry cost and infrastructure requirements that are disproportionate for medium-depth perimeter segments. That gap, centred on the 1000 to 2000 m band, is where most personnel incursion events are actually detected in active border and facility perimeter operations.
Starlight Colour Imaging Across the Medium-Range Band
The XHC2025C targets this segment directly with a 22.5 mm F1.2 lens on a starlight-class CMOS sensor rated to 0.001 lux at 10 fps in colour mode. Person detection reaches 1910 m and vehicle detection extends to 4200 m, covering the medium-range perimeter band in full-colour passive imagery without active illumination. The F1.2 aperture at 22.5 mm provides greater light collection than F1.4 alternatives at equivalent focal lengths, sustaining colour imaging through the pre-dawn hours when monochrome fallback is typically triggered on competing systems operating at the same range.
Border Post and Forward Observation Applications
Border observation posts monitoring approach routes across flat or gently undulating terrain have standardised on the 1500 to 2000 m person detection band as the minimum requirement for providing adequate intercept response time. At 1910 m rated detection range, the XHC2025C covers that requirement with a margin that accounts for atmospheric haze and target aspect variations that routinely reduce effective range in operational conditions. Standard IP connectivity and compatibility with pan-tilt platforms allow the system to feed directly into existing command-and-control infrastructure without proprietary integration hardware, reducing deployment lead time for new observation post installations.
Complementary Role in Layered Perimeter Networks
Facility security programmes that layer cameras across detection, recognition, and identification bands use medium-range systems like the XHC2025C to bridge the coverage gap between outer long-range sensors and inner identification cameras near access control points. The 22.5 mm focal length provides a field of view suited for tracking moving personnel across the mid-zone while delivering enough angular resolution for recognition-class imagery at 900 to 1000 m, supporting operator decision-making before a contact reaches the inner sensor layer. For programmes standardising a tiered network across multiple perimeter sites, the XHC2025C provides a consistent medium-range capability that integrates into the same video management infrastructure as the wider sensor family.
