Annke 4K POE Bullet Camera 4mm Lens 100ft Night Vision Surveillance Security System

4K POE Bullet Camera with 4mm Lens

This single-camera surveillance system delivers 3840 by 2160 resolution at a 16:9 aspect ratio using a 1/2.4 inch progressive scan CMOS sensor. The 4mm F1.6 lens provides a fixed field of view suited for monitoring entry points or driveways. Power over Ethernet simplifies installation by carrying both data and power over one cable. It is designed for homeowners or small businesses wanting a standalone IP camera with on-board recording up to 512 GB.

Sustained Recording and Compression Efficiency

The camera encodes the main stream with H.265+ or H.265 compression, keeping bitrates between 32 Kbps and 16 Mbps during continuous capture. At 50 Hz it maintains 12.5 fps at full 4K, while 60 Hz operation reaches 15 fps at the same resolution. Sub-stream recording runs at 20 fps in 720p, 480p or 360p for remote viewing without saturating the uplink. Motion Detection 2.0 filters humans and vehicles, cutting false alerts by up to 99 percent during long-term deployment.

Environmental Resilience and Night Operation

An IP67 rating protects the bullet housing against dust and water ingress for permanent outdoor mounting. Dual-light technology switches between infrared and colour night vision out to 100 feet, triggered automatically by detected objects. Built-in 3D DNR and 120 dB WDR balance exposure in high-contrast scenes day or night. The integrated microphone and speaker enable two-way audio, while selectable sound and light alarms add active deterrence when events occur.
