The XHC6160C-ABF delivers 5400 m person detection at 0.0008 lux in full colour via a 160 mm F1.7 ABF lens, addressing long-range passive colour surveillance across border and coastal perimeter deployments.
National border surveillance programmes that have historically accepted monochrome imaging as the price of long-range passive night detection are encountering a capability revision: full-colour starlight CMOS technology has now closed the sensitivity gap enough that long-range detection and colour rendering can coexist in a single fixed-mount sensor without active illumination. That revision is changing procurement conversations, particularly for installations covering open terrain and coastal approaches where vehicle identification and personnel clothing colour represent actionable intelligence that greyscale imagery cannot provide.
Colour Starlight Detection at 5400 m Without Illumination
The XHC6160C-ABF enters that market shift as a full-HD colour ultra-low-light surveillance camera pairing a 1.5-inch CMOS sensor with 10 µm pixel pitch against a 160 mm equivalent F1.7 high-aperture lens, achieving person detection to 5400 m at 0.0008 lux minimum illumination in colour mode. Recognition extends to 1350 m and identification to 840 m day and night, validated per US NVESD standards against a 1.7 m x 0.5 m human target. Auto Back Focus compensates for thermal drift at 160 mm focal length, ensuring focus integrity is maintained across overnight temperature cycles without field service intervention.
Border Surveillance and Maritime Perimeter Applications
Fixed perimeter installations along border corridors and coastal observation points have a common operational requirement: early detection at the outer range band with enough colour resolution at recognition range to support operator decision-making before a contact closes to the enforcement boundary. At 5400 m colour detection range, the XHC6160C-ABF provides that outer-band capability from a single fixed position, covering the approach geometry of most coastal patrol corridors in passive mode that avoids active illumination signature. The wider 21° horizontal field of view at 160 mm compared to narrower alternatives provides broader scene context alongside the telephoto range, reducing the slewing frequency that operators managing perimeter watch positions must perform to maintain continuous contact coverage across a sector.
Integration Into Layered Perimeter Networks
Programme offices assembling layered perimeter surveillance networks across multiple range tiers can deploy the XHC6160C-ABF at the outer detection layer alongside mid-range XHC6060C-ABF and short-range XHC6016C nodes, all sharing the same ONVIF, RTSP, and PELCO protocol stack over RJ45 with optional Wi-Fi and 4G LTE. The ABF remote focus on the 160 mm model allows the outer-layer sensor to be installed and calibrated from the control centre without deploying technicians to remote tower positions after initial installation. The XHM6160 bare module variant supports OEM enclosure integration for programmes requiring custom mechanical configurations at long-range observation nodes.
