XHC6160B-ABF Long-Range Ultra Low Light B&W Camera
0.0004 lux min. illumination, 7700 m person detection, 160 mm ABF monochrome starlight surveillance camera.
System Detail
What It Is
The XHC6160B-ABF is an Ultra Low Light EO Surveillance Camera built around a 1.5-inch monochrome CMOS sensor with 10 µm pixel pitch, paired with a 160 mm equivalent F1.7 high-aperture lens to deliver passive full-HD black-and-white imaging under starlight and extreme low-illumination conditions, achieving the longest detection range in the XHC6 Series without any auxiliary light source.
Performance
The camera achieves a minimum effective illumination of 0.0004 lux at 25 fps (0.0002 lux at 5 fps) in monochrome mode, exceeding the sensitivity of the colour variant by a factor of two. Based on US NVESD measurement standards against a 1.7 m × 0.5 m human target, the XHC6160B-ABF delivers person detection at 7700 m, recognition at 1920 m, and identification at 1200 m day and night. Dynamic range reaches 72 dB with WDR off and up to 120 dB with WDR on, at a native resolution of 1920 × 1080 Full HD.
Key Technical Features
- Monochrome CMOS operation delivers approximately 2× lower minimum illumination than the equivalent colour variant, maximising passive detection range under starlight and overcast night-sky conditions.
- Auto Back Focus (ABF) with motorised remote focus adjustment enabling installation in elevated or inaccessible locations without on-site optical alignment.
- ONVIF / RTSP / PELCO protocol compliance over RJ45 Ethernet, with integrated Wi-Fi (standard) and optional 4G LTE for wireless deployment scenarios.
- Multi-frame low-noise image processing with adjustable 3D noise reduction and electronic image stabilisation, maintaining image fidelity at frame rates from 5 to 30 fps.
Platform Compatibility
The XHC6160B-ABF is designed for fixed-mount outdoor deployment on mast, wall, or tower structures in border surveillance, perimeter security, maritime monitoring, and critical infrastructure protection scenarios where maximum passive detection range takes priority over colour imaging; the XHM6160B module variant is available for OEM integration into custom enclosures and multi-sensor platforms.
Monochrome Maximum Sensitivity
Monochrome CMOS operation eliminates the colour filter array, approximately doubling photon capture efficiency relative to the colour variant at the same pixel pitch and aperture. This directly extends the passive detection range from 5400 m (colour) to 7700 m without any change to optics or housing.
ABF Remote Focus on 160 mm Lens
Auto Back Focus uses a motorised rear-element drive controlled remotely over the network interface, allowing precise focus lock on elevated masts or restricted-access installations without technician dispatch. The 160 mm F1.7 lens provides the narrow field of view required for extreme long-range target discrimination.
NVESD-Standard Long-Range DRI
DRI is validated against a 1.7 m × 0.5 m human target per US NVESD methodology, yielding 7700 m detection, 1920 m recognition, and 1200 m identification in monochrome mode day and night. These figures represent the series performance ceiling for passive imaging in this focal-length class.
Adaptive Frame Rate for Extreme Low Light
Reducing frame rate to 5 fps lowers minimum effective illumination to 0.0002 lux, extending operational capability in environments well below the threshold of any colour camera. Multi-frame noise processing and 3D noise reduction maintain usable image quality at the sensitivity limit.

Designed for the Field
Maximum-Range Border Surveillance
The XHC6160B-ABF is selected for border surveillance deployments where passive detection range is the primary operational requirement and colour rendering is secondary to extending detection distance under extreme low-light conditions.
Critical Infrastructure Night Watch
Infrastructure protection operators deploy the B-variant for unlit perimeter zones and remote facility boundaries where the additional sensitivity of monochrome CMOS provides reliable person detection beyond the range achievable by colour cameras.
OEM and System Integrator Platform
System integrators embed the XHM6160B module variant into multi-sensor surveillance platforms and custom enclosures requiring the longest-range passive monochrome imaging core in the XHC6 Series.
Maximum-Range Border Surveillance
The XHC6160B-ABF is selected for border and frontier surveillance operations where passive detection range is the primary criterion and colour imaging is not required. Monochrome CMOS sensitivity extends person detection to 7700 m without active illumination or scene disclosure. US NVESD-standard DRI performance against a 1.7 m × 0.5 m human target yields recognition at 1920 m and identification at 1200 m, enabling positive target characterisation at ranges beyond the detection capability of colour variants.
- Person Detection Range: 7700 m (day and night)
- Person Recognition Range: 1920 m
- Min. Illumination: 0.0004 lux @ 25 fps
- Focal Length: 160 mm equivalent, F1.7
Unlit Perimeter and Infrastructure Watch
Remote facilities, power stations, and pipeline perimeters with no ambient lighting present the most demanding sensitivity requirements. The XHC6160B-ABF minimum illumination of 0.0002 lux at 5 fps covers complete darkness scenarios where colour cameras cannot produce usable imagery. ABF motorised remote focus eliminates technician site visits after installation, reducing ongoing maintenance cost at remote or hazardous-environment locations; on-board 32 GB storage (expandable to 128 GB) supports standalone operation independent of network infrastructure.
- Min. Illumination (5 fps): 0.0002 lux
- Internal Storage: 32 GB default, max 128 GB
- Focus Mode: ABF remote motorised
- Operating Temp: −40 °C to +70 °C
Long-Range Monochrome OEM Integration
System integrators requiring the highest passive sensitivity in the XHC6 Series select the XHM6160B module variant for embedding into multi-sensor towers, vehicle-mount housings, and long-range coastal surveillance enclosures where monochrome imaging is preferred over colour. SDK and HTTP API support are available upon request; ONVIF and RTSP compliance ensures compatibility with existing VMS and C2 infrastructure without additional middleware.
- Sensor: 1.5 inch monochrome CMOS, 10 µm pixel pitch
- Identification Range: 1200 m (day and night)
