The XHC6060C-ABF delivers 3000 m person detection at 0.0006 lux full-colour starlight imaging via a 65 mm F1.2 ABF lens, providing wide-area passive colour coverage for medium-range perimeter and coastal surveillance nodes.
Perimeter security programmes covering mid-range terrain segments between 1500 m and 3500 m have long occupied an awkward middle ground in sensor selection: long-range telephoto systems provide more range than the zone requires at the cost of field of view that forces motorised slewing, while shorter-focal-length systems cover the zone width but sacrifice the pixel density at range that supports reliable person recognition. The 65 mm class fills that gap with a field of view wide enough for sector coverage and a detection range that reaches across the full perimeter segment without mechanical tracking, and the availability of that capability at starlight colour sensitivity changes the calculus for programmes where colour identification matters operationally.
Medium-Range Colour Starlight Surveillance at 65 mm
The XHC6060C-ABF delivers colour person detection to 3000 m at a minimum illumination of 0.0006 lux at 25 fps, built around a 1.5-inch CMOS sensor with 10 µm pixel pitch behind a 65 mm equivalent F1.2 high-aperture lens. Recognition extends to 750 m and identification to 470 m day and night, providing classification-quality colour imagery across the mid-perimeter zone in passive mode without active illumination. The 21° horizontal field of view at 65 mm provides wider scene context than longer-focal-length alternatives at comparable detection range, covering a perimeter arc segment in a fixed-stare configuration without requiring sensor slewing to maintain contact continuity as personnel move laterally across the observation zone.
Maritime Port and Coastal Perimeter Applications
Port security installations monitoring vessel approach lanes and waterside perimeters require sensors that combine detection range with colour rendering for vessel marking and personnel identification, tasks that monochrome sensors address only partially. At 3000 m colour detection range, the XHC6060C-ABF covers the approach geometry of most port entrance corridors and shoreline perimeter segments in passive starlight imaging, with AI video analytics supporting automated detection at ranges above 150 m. The ABF remote focus mechanism allows initial calibration and periodic adjustment of the 65 mm optic from the operations centre, a practical necessity for sensors installed on elevated maritime infrastructure positions where on-site access requires vessel deployment or crane access.
Building a Layered Network With the XHC6 Family
The XHC6060C-ABF functions as the medium detection layer in XHC6 Series tiered perimeter deployments, sitting between the XHC6160C-ABF outer detection nodes and the XHC6016C inner identification nodes to provide recognition-class colour coverage across the zone where contact tracking transitions from early detection to intercept cueing. All three models share ONVIF, RTSP, and PELCO protocol compliance over RJ45 with Wi-Fi and optional 4G LTE, integrating into the same VMS infrastructure without separate driver stacks or interface adapters.
