Medium-Range Super Night Vision Camera Module
0.0007 lx @ 5 fps starlight imaging, 1910 m person detection, 22.5 mm medium-range fixed-focus camera.
Medium-to-Long Range Starlight Surveillance with Fixed Focus
What It Is
The XHM2025C 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 22.5 mm F1.2 fixed-focus telephoto lens and a 27.8° horizontal field of view to deliver 24/7 full-colour starlight imaging at medium-to-long surveillance distances.
Performance
The XHM2025C achieves a minimum effective illumination of 0.001 lx at 25 fps and 0.0004 lx at 2 fps, with dynamic range of 72 dB (WDR off) to 120 dB (WDR on). Person-target DRI validated per US NVESD standards against a 1.7 m × 0.5 m human target: 1910 m detection, 470 m recognition, and 300 m identification at day and night. AI video analytics starts at ≥ 120 m with manual zoom extending effective analytics range by up to three times.
Key Technical Features
- ONVIF / RTSP / PELCO and HTTP API support enable direct integration with enterprise VMS platforms and PTZ controller infrastructure without proprietary middleware.
- 22.5 mm F1.2 fixed-focus optics provide a 27.8° horizontal field of view, balancing detection range with scene coverage area for mid-range perimeter and border segments.
- Adaptive frame rate exposure from 30/25 fps to 2 fps ensures continuous colour imaging at minimum illumination while maintaining higher frame rates in better-lit conditions.
- Optional 4G LTE connectivity and WebRTC licensing support autonomous remote operation without fixed network cabling.
Platform Compatibility
The XHM2025C is suited for fixed deployment on surveillance poles, border segment towers, and coastal monitoring stations where a 27.8° horizontal FOV at medium-to-long range provides effective corridor coverage. The XHM2025M module variant supports OEM integration into custom platform enclosures.
Medium-Angle Starlight Colour Imaging
The XHM2025C pairs a 0.8-inch CMOS sensor with a 22.5 mm F1.2 fixed-focus lens, providing a 27.8° horizontal field of view for 24/7 full-colour starlight imaging at medium-to-long surveillance ranges. The optics balance detection range extension against scene coverage width.
1910 m Person Detection Performance
DRI distances are measured per US NVESD methodology against a 1.7 m × 0.5 m human target, achieving 1910 m detection, 470 m recognition, and 300 m identification at day and night. AI analytics activates at ≥ 120 m, with manual zoom extending the analytics range by up to three times.
Fixed-Focus Operational Simplicity
The fixed-focus design permanently calibrates the lens for the operational range, eliminating focus motor maintenance and drift-induced image degradation common in motorised focus systems deployed in outdoor environments across temperature cycles.
Adaptive Exposure and Network Streaming
Three automatic exposure modes adjust frame rate from 30/25 fps to 2 fps as ambient light decreases, extending minimum effective illumination to 0.0004 lx. ONVIF, RTSP, and HTTP API provide flexible integration with VMS platforms and network recording systems.

Designed for the Field
Perimeter and Border Segment Surveillance
The XHM2025C provides 1910 m person detection across a 27.8° horizontal field of view, suited for border segment towers and perimeter surveillance applications where medium-angle coverage at long range is required.
Coastal and Maritime Monitoring
Its 22.5 mm telephoto optics and 1910 m detection range make the XHM2025C suitable for coastal monitoring stations and port perimeter surveillance operating under starlight and low-light conditions.
OEM and System Integration
The XHM2025M module provides the same imaging performance in a bare format, enabling OEM integrators to embed medium-to-long range starlight imaging into custom enclosures and multi-sensor surveillance platforms.
Border Segment and Perimeter Surveillance
The XHM2025C provides 1910 m person detection across a 27.8° horizontal field of view, suited for deployment along border segments and perimeter corridors where medium-angle coverage at extended range is required. Continuous 24/7 full-colour output is maintained under natural starlight without auxiliary illumination. Person recognition at 470 m and identification at 300 m allow operators to classify contacts approaching from long range before they reach controlled zones, validated per US NVESD standards.
