Hear What Matters — Built-in Audio Monitoring
This dome camera includes a built-in microphone for real-time audio capture. You can hear conversations, alarms, or suspicious sounds directly through your NVR or Hik-Connect app. No need to buy or install separate audio devices — it's all in one compact unit.
Clear Images Even Against Harsh Backlight
120dB True WDR (Wide Dynamic Range) balances bright and dark areas in the same scene. Whether it's a sunlit doorway or a warehouse with bright windows, you get usable video without blown-out highlights or crushed shadows. The 1/3" progressive scan CMOS sensor captures detail down to 0.005 Lux in color.
Built Tough for Outdoor Installation
Rated IP67 for dust and water ingress, this camera survives rain, snow, and hose-down cleaning. IK08 vandal resistance protects against physical impact. The fixed 2.8 mm lens gives a 104.3° horizontal field of view — wide enough for corridors, entrances, and parking areas.
Smart Alerts That Save You Time
AcuSense technology uses deep learning to classify humans and vehicles. You only get alerts for real threats — not for swaying trees, passing cars, or stray animals. This reduces false alarm response time and cuts hours of useless footage review. Works with H.265+ compression to save bandwidth and storage.

Frequently Asked Questions
Is this camera good for outdoor night surveillance?
Yes. It has 30m IR night vision and a 0.005 Lux minimum illumination sensor, so it captures clear black-and-white footage in total darkness. The IP67 rating means it handles rain and dust outdoors.
Does this camera have a built-in microphone?
Yes. A built-in mic captures audio in real time. You can listen through your NVR or the Hik-Connect mobile app without adding external microphones.
How does AcuSense reduce false alarms?
AcuSense uses on-camera AI to classify humans and vehicles. It ignores motion from animals, leaves, rain, or headlights. You only get alerts when a person or vehicle is detected.
