i-PRO WV-U31401-F2LG 4MP Indoor Compact Dome IP Camera

i-PRO WV-U31401-F2LG 4MP Indoor Compact Dome Camera

The i-PRO WV-U31401-F2LG is a 4MP indoor compact dome IP camera engineered for surveillance deployments where space is constrained and reliable low-light performance is essential. This wired PoE camera combines a 1/2.7-inch CMOS sensor with an f/2.1 fixed lens to deliver sharp, detailed imagery in diverse lighting conditions. Its compact form factor, wide 121° horizontal field of view, and integrated IR LED illumination make it well-suited for retail, office, corridor, and entry-point monitoring applications.

Key Features

• 4MP Resolution with Flexible Frame Rates: Captures 2560×1440 video at 30 fps or 25 fps, with fallback resolutions down to 320×180 in 16:9 mode. Also supports 4:3 aspect ratio up to 2048×1536 at 15 fps, providing flexibility for diverse deployment scenarios.
• Exceptional Low-Light Performance: Achieves 0.66 lux color operation (30IRE, F2.1, 1/30s) and 0.38 lux in black-and-white mode without IR. With IR LEDs engaged, reaches 0 lux black-and-white operation for true 24/7 surveillance in near-total darkness.
• Integrated IR Night Vision: Built-in IR LED array with three adjustable intensity levels (High, Middle, Low). Maximum irradiation distance reaches 14 meters at 30IRE and 10 meters at 50IRE, supporting perimeter and indoor entry monitoring.
• Advanced Video Processing: Powered by Ambarella S3LM System-on-Chip. Supports H.265 and H.264 compression with MJPEG fallback, Super Dynamic Range up to 102 dB, and configurable motion detection across 4 separate zones.
• Wide Field of View: 121° horizontal field of view with 2.4mm focal length enables comprehensive coverage in confined spaces without requiring pan-tilt-zoom functionality.
• PoE Power Delivery: Class 2 PoE device consuming only 8.6W, simplifying installation and reducing cabling complexity in retrofit and new-build projects.
• Compact Rugged Design: Dome form factor (ø104 mm × 51 mm) with ABS resin main body and smoke-tinted polycarbonate front panel, weighing just 280 grams for flush ceiling and wall mounting.
• Local Storage Support: microSD card slot supports up to 512GB capacity for independent backup recording and edge-based event archival.
• ONVIF Compliance: Profiles G, S, and T support ensure interoperability with third-party VMS platforms and NVR systems.

Applications

Ideal for retail checkout areas, office hallways, building lobbies, stairwells, warehouse aisles, and perimeter entry points where compact mounting, night vision, and reliable PoE operation are required. The 121° wide field of view and low-light sensitivity eliminate the need for supplemental lighting in most indoor environments.

James Everett

The WV-U31401-F2LG delivers exceptional value for budget-conscious deployments requiring dependable low-light surveillance. Its 102 dB dynamic range and 0.66 lux color sensitivity rival cameras costing significantly more, while the compact 104mm dome housing fits seamlessly into drop ceilings and narrow wall cavities. The f/2.1 aperture and 2.4mm lens strike a careful balance—wide enough (121° horizontal) for corridor and hallway coverage, yet with sufficient focal length to resolve detail at distance (5.2m recognition range).

H.265 codec support reduces bandwidth and storage overhead in multi-camera deployments, and native ONVIF compliance ensures vendor lock-in is avoided. The 14-meter IR range is adequate for indoor perimeter doors and loading bays but may fall short in large outdoor vestibules; consider supplemental lighting for those scenarios. PoE Class 2 operation (8.6W) is energy-efficient and allows long cable runs without requiring midspan injectors, simplifying infrastructure planning.
