Long Range Low Light Night Vision Camera Module
0.001 lx @ 5 fps starlight imaging, 9000 m person detection, 290 mm ABF ultra-long-range camera.
Ultra-Long-Range Starlight Surveillance with Auto Back Focus
What It Is
The XHM2290C-ABF is an ultra low light electro-optical surveillance camera of the Ultra Low Light EO Surveillance Camera class, combining a 0.8-inch CMOS sensor with a 290 mm equivalent F1.7 high-aperture telephoto lens to achieve 24/7 full-colour starlight imaging at the longest civilian surveillance ranges available in this form factor.
Performance
The XHM2290C-ABF reaches a minimum effective illumination of 0.001 lx at 5 fps and 0.0007 lx at 2 fps, with dynamic range of 72 dB (WDR off) to 120 dB (WDR on). Person-target DRI performance validated per US NVESD standards against a 1.7 m × 0.5 m human target: 9000 m detection, 2330 m recognition, and 1440 m identification at day and night. AI video analytics activates at ≥ 485 m with manual zoom capable of tripling effective analytics range.
Key Technical Features
- Auto Back Focus (ABF) with remote motorised adjustment allows focus to be set and refined from a control centre, critical for 290 mm telephoto precision at extreme range.
- ONVIF / RTSP / PELCO and HTTP API protocol support enables integration with enterprise VMS platforms without proprietary middleware.
- Adaptive frame rate exposure from 30 fps to 2 fps automatically extends sensitivity as ambient light drops, maintaining imaging continuity across all nocturnal conditions.
- Internal storage up to 128 GB and optional WebRTC licensing support edge recording and remote real-time access for off-grid or bandwidth-constrained installations.
Platform Compatibility
The XHM2290C-ABF is designed for fixed mast-mount and tower deployment across wide-area border monitoring networks, maritime coastal surveillance stations, and long-range critical infrastructure observation posts. Its 4G LTE option supports autonomous operation at sites without wired network access.
Extreme-Range Starlight Colour Imaging
The XHM2290C-ABF pairs a 0.8-inch CMOS sensor with a 290 mm F1.7 telephoto lens, achieving 24/7 full-colour imaging under natural starlight at detection ranges exceeding 5 km. No auxiliary illumination is required at any operational distance.
9000 m Person Detection Performance
DRI distances are measured per US NVESD methodology against a 1.7 m × 0.5 m human target, confirming 9000 m detection, 2330 m recognition, and 1440 m identification at day and night. AI video analytics engagement starts at ≥ 485 m with zoom-assisted extension.
ABF Remote Focus for Telephoto Precision
At 290 mm equivalent focal length, millimetre-accurate focus is critical for image sharpness at multi-kilometre range. ABF provides motorised remote focus control over the network, eliminating on-site calibration visits at elevated or remote installation points.
Adaptive Sensitivity Exposure Modes
Three automatic exposure modes step frame rate from 30/25 fps to 10, 5, or 2 fps as illumination falls, extending minimum sensitivity to 0.0007 lx at 2 fps. WDR adjustment from 72 dB to 120 dB maintains dynamic scene reproduction across dawn-to-dusk transitions.

Designed for the Field
Wide-Area Border Monitoring
The XHM2290C-ABF enables wide-area situational detection at up to 9000 m, designed for border surveillance networks requiring continuous night coverage across large open terrain.
Maritime Coastal Surveillance
Its 290 mm telephoto optics and 9000 m detection range make the XHM2290C-ABF suitable for coastal surveillance stations monitoring maritime approaches under low-light and starlight conditions.
OEM and System Integration
The XHM2290M-ABF module variant provides the same imaging core in a bare format for OEM customers requiring custom mechanical integration at the same extreme-range performance level.
Wide-Area Border Surveillance
The XHM2290C-ABF provides wide-area situational detection at up to 9000 m, supporting border networks where a single camera must monitor extended open terrain sectors under starlight conditions. Continuous 24/7 full-colour output removes the operational gap experienced with conventional cameras between dusk and dawn. Recognition at 2330 m and identification at 1440 m against a 1.7 m × 0.5 m human target, validated per US NVESD standards, allow threat classification before any target reaches actionable range.
