High-Definition 4K Security with Intelligent Analytics

Delivering ultra-sharp 8 MP (3840 × 2160) video at up to 20 fps, this outdoor fixed bullet network camera captures critical visual details across commercial and residential perimeters. Powered by intelligent deep-learning algorithms, the camera provides line crossing and intrusion detection focused on human and vehicle classification, significantly minimizing false triggers caused by foliage, rain, or small animals.

Advanced Low-Light Imaging and True WDR

Equipped with a high-sensitivity 1/2.8" Progressive Scan CMOS sensor and an F1.6 aperture, the camera achieves low-light color performance down to 0.005 Lux. When complete darkness occurs, integrated Smart IR illumination activates automatically to deliver even night coverage up to 40 meters. Built-in 120 dB True WDR, 3D DNR, and BLC ensure balanced image clarity against strong backlight and high-contrast glare.

Flexible Deployment, Audio, and Storage

  • Flexible Optical Coverage: Available in 2.8 mm (107° FOV), 4 mm (87° FOV), and 6 mm (54° FOV) fixed lens options to match varied detection distances.
  • Real-Time Audio Security: Built-in microphone (-U model) captures environmental audio with integrated background noise filtering.
  • Efficient Bandwidth & Edge Storage: Supports H.265+ video compression for optimized storage efficiency alongside a built-in microSD slot supporting up to 512 GB.
  • Outdoor Durability: Rugged IP67-rated aluminum alloy enclosure withstands harsh weather from -30 °C to 60 °C, powered via 12 VDC or standard PoE (802.3af).
