The XHC1604U12C delivers Full HD 0.0007 lux imaging and 1100 m person detection via a 12 mm lens and USB 3.0, targeting coastal observation posts and border corridor surveillance platforms requiring extended-range passive night imaging.
Coastal and border surveillance programmes operating compact sensor platforms along monitored corridor segments face a persistent coverage geometry challenge: sensors with enough angular resolution to classify a person at 1000 m typically deliver a field of view narrow enough that moving contacts can exit the sensor frame before an operator can initiate tracking, while wider sensors that maintain contacts in frame lack the pixel density at range for reliable classification. Finding the focal length that balances classification resolution against frame retention at 1000 m-class range in a USB camera module has been difficult because most USB sensors in the low-light class have been optimised for wide-angle operation at shorter ranges.
Extended-Range Low-Light USB Imaging at 12 mm
The XHC1604U12C addresses that balance with a 12 mm F1.0 lens on a Full HD 1920 × 1080 BSI CMOS sensor rated to 0.0007 lux minimum illumination in monochrome mode. Person detection reaches 1100 m and vehicle detection extends to 2500 m, providing the range geometry for classification-class imaging at distances relevant to coastal observation post and border corridor surveillance from compact fixed or drone-mounted sensor platforms. USB 3.0 connectivity with UVC driver compatibility allows the module to integrate with standard embedded compute platforms without custom driver development, maintaining the field serviceability and logistics simplicity that USB-interface sensors provide at the fleet scale.
Coastal Observation Post and Airborne Corridor Surveillance
Fixed coastal observation posts monitoring approach corridors and shoreline segments require sensors that can classify vessel contacts and personnel on the waterline at ranges beyond 800 m to provide intercept cueing before contacts reach the enforcement engagement boundary. At 1100 m rated person detection, the XHC1604U12C provides that classification geometry from a compact fixed-mount installation without the active illumination or thermal sensor overhead that alternative approaches impose on coastal post power and logistics budgets. Compact drone payloads assigned to corridor surveillance at altitudes of 100 to 200 m benefit from the 12 mm focal length geometry, which provides the angular resolution to classify person contacts along a corridor from altitude without requiring sensor slewing that compact single-axis gimbal systems cannot perform at the required speed for moving contacts.
Standardised Range Coverage Across the XHC1604U Series
The XHC1604U series covers short, medium, and extended detection ranges across the 7 mm, 12 mm, and 16 mm focal length variants while maintaining a common USB 3.0 interface and UVC driver stack across all variants. Programme offices standardising sensor procurement across multiple platform types benefit from that interface consistency, which allows a single software integration effort to cover the full range band without separate driver qualification for each focal length. The XHC1604U12C occupies the medium-to-extended range position in that family, suited to programmes that require person classification at 1000 m class range from compact platforms where the 7 mm variant falls short of the required detection distance and the 16 mm variant delivers more range than the operational requirement demands.
