Ultra HD 16MP Active Defense with AI Noise Reduction & Marine-Grade Shielding

The Hikvision DS-2CD3H167G3-LIZSUY/SL is a flagship 16 MP motorised varifocal turret network camera designed for high-security perimeters, port terminals, logistics facilities, critical infrastructure, and chemical processing plants. Driven by HIK AI-ISP processing technology, it suppresses image noise to a remarkable degree and records pristine 4608 × 3456 detail in even the most challenging low-light scenes. On-board active deterrence — a white light strobe paired with a high-decibel audio alarm — and NEMA 4X marine-grade anti-corrosion protection (-Y) let it hold the line 24/7 in severe outdoor conditions.

Deep Learning Classification & Spatial Dual-Microphone Communications

The DS-2CD3H167G3-LIZSUY/SL applies deep learning analytics that lock onto human and vehicle targets only, discarding nuisance triggers such as windblown foliage and weather movement. Its arrayed dual microphones, integrated 2W speaker, and scene-adaptive Wide Dynamic Range (WDR) support spatial noise reduction, producing clean two-way audio and reliable sound-event response. With Smart Hybrid Light technology, a remotely adjustable motorised 2.7–13.5 mm zoom, and NEMA 4X anti-corrosion shielding (-Y), the turret sustains sharp 16 MP awareness at the toughest marine and industrial sites.

Active Strobe Light & Audio Alarm (/SL)

On any AI-classified detection, the camera immediately directs an intense white strobe and loud, customisable audio alerts at the target, discouraging intruders before an incident develops.

NEMA 4X Anti-Corrosion Rating (-Y)

A marine-grade anti-corrosion finish protects the housing against salt fog, persistent humidity, acidic atmospheres, and harsh chemical exposure at coastal and industrial installations.

Frequently Asked Questions

What is the real-world benefit of 16MP resolution?

With 4608 × 3456 pixels, the sensor provides such dense detail that operators can digitally zoom well into a wide scene and still clearly make out small elements like faces or number plates.

What corrosion protection comes with the "-Y" suffix?

"-Y" signifies NEMA 4X anti-corrosion certification, meaning the housing is engineered to endure salt spray, chemical contact, and acidic weather typical of coastal and industrial environments.

How does HIK AI-ISP raise image quality?

HIK AI-ISP uses deep-learning noise reduction to retain true colour, contrast, and edge sharpness in darkness — scenes where standard cameras degrade into grain and motion blur.

Can installers adjust the lens remotely?

Yes. Optical zoom and autofocus on the motorised 2.7–13.5 mm lens are fully adjustable from the web browser interface or client software, with no need to physically access the camera.
