ZV-LESV075HC | 1280x1024 75mm Motorized Lens IP Thermal Module | HD Megapixel IR Core
The ZanVision ZV-LESV075HC is a premier 1280x1024 high-definition IP thermal imaging module featuring a precision 75mm motorized focus lens. Designed as the core imaging engine for mid-to-long-range electro-optical systems, this module leverages a 12um pixel pitch uncooled VOx detector - delivering 1.3 megapixels of thermal resolution, a significant advancement over conventional 640x512 modules. The integrated 75mm F1.0 lens with motorized focus enables remote focus adjustment over Ethernet/RS-485, eliminating the need for manual field calibration in deployed systems. ONVIF Profile G compliance ensures plug-and-play integration with leading VMS platforms including Milestone, Genetec, and Digifort.
Technical Distinction: 1280x1024 vs Standard 640x512
4x Pixel Density Advantage: The 1.3MP thermal image provides substantially more detail for target classification - a vehicle that occupies 40x40 pixels on a 640 detector becomes an 80x80 pixel image on this module, crossing the recognition threshold defined in the DRI standard.
Wider Coverage With Equal Resolution: A single 1280x1024 module can cover the same area as four 640x512 modules while maintaining equivalent pixels-on-target, reducing system cost, weight, and integration complexity.
Enhanced AI/Video Analytics Input: Machine learning object classifiers achieve higher confidence scores when fed higher-resolution thermal imagery. The 1280x1024 input improves detection probability and reduces false alarm rates compared to 640-class alternatives.
Integration Scenarios
Mid-Range PTZ & Gimbal Systems: The 75mm focal length provides optimal DRI performance (detection ~13.5km human) for pan-tilt platforms covering perimeters up to 5km with recognition throughout the zone.
Coastal Surveillance Stations: Shore-based monitoring of vessel traffic, illegal fishing, and smuggling activities where the high resolution enables classification of small craft at tactically useful ranges.
Critical Infrastructure Protection: Fixed-site monitoring of dams, nuclear facilities, and strategic assets where the megapixel resolution justifies the investment over 640-class alternatives through superior threat assessment capability.
