Uniview Uniarch UNV 3MP Wi-Fi Dual Light Bullet Camera Uho-B2D-M3F4D

Uniview Uniarch UNV 3MP Wi‑Fi Dual Light Bullet Camera Uho-B2D-M3F4D

The Uniview Uniarch Uho-B2D-M3F4D is a 3MP fixed-lens camera designed for reliable property monitoring in outdoor and semi-outdoor environments. Its 4.00mm lens delivers a narrower, more focused field of view, making it ideal for watching over entry points, gates, driveways, or other key access areas where detail matters.

Features

• 3MP resolution for high-quality video capture
• 4.00mm fixed lens for focused monitoring
• Infrared night vision with a 20-metre range
• Supports up to 512GB MicroSD local storage
• Weather-resistant housing for outdoor use
• Suitable for homes, offices, and small business premises

The camera captures sharp 3MP footage and ensures uninterrupted visibility at night with built-in infrared (IR) LEDs, providing up to 20 meters of coverage in low-light or complete darkness. A built-in MicroSD card slot supports up to 512GB of local storage, allowing continuous or event-based recording without external devices.
