Details
See Clearly Against Harsh Backlight
Strong sunlight or bright storefronts can ruin a camera image. This Hikvision speed dome uses 120dB True WDR to balance light and dark areas, so faces and license plates stay sharp even with the sun behind them. You get usable evidence, not a silhouette.
Zoom In on the Details That Matter
The 25x optical zoom (4.8 to 120mm) brings distant objects close. Read a license plate from 300ft away or inspect a delivery label at the loading dock. With 16x digital zoom, you can push in even further when you need a closer look.
Full Coverage with Fast, Precise Movement
Pan 360° endlessly and tilt from -5° to 90° to cover every corner of your property. The 300°/s pan speed keeps up with fast-moving subjects, while 300 presets let you jump to key areas instantly. Set up patrols and patterns for automated monitoring.
Built for Outdoor Use, Easy to Install
The IP66-rated housing protects against rain, dust, and extreme temperatures from -30°C to 65°C. Power it with 12V DC or PoE+ (802.3at) for flexible installation. Local SD card storage (up to 256GB) keeps recording on-site with no monthly fees.
