12MP Motorised Varifocal Dome Camera for Detailed Day and Night Surveillance

The Hikvision DS-2CD37C7G3T-LIZSU(Y) is a 12MP dome network camera aimed at high-detail monitoring of commercial, industrial and exposed outdoor locations. Built around a 1/1.8-inch sensor capturing up to 4608 × 2592 resolution, it pairs a motorised 2.7–13.5 mm varifocal lens — remotely adjustable during commissioning — with HIK AI-ISP processing, scene-adaptive WDR and Smart Hybrid Light, so usable image detail is preserved from bright daylight through to low-light and night-time scenes.

Key Specifications at a Glance

• Resolution / Sensor: 12MP / 1/1.8-inch CMOS
• Motorised Lens: 2.7–13.5 mm Varifocal
• Night Illumination: IR + White Light to 40 m
• Protection: IP67 / IK10 / NEMA 4X

High-Resolution Imaging Backed by Smarter Event Detection

The camera records up to 20 frames per second at its full 12MP resolution, and up to 25 fps at 4K and lower resolutions under Australian 50 Hz operation. Deep-learning person and vehicle classification keeps perimeter events focused on the targets that matter. Face capture, line crossing, intrusion, region entrance and region exiting functions are supported as well, subject to system configuration and compatible recording equipment.

HIK AI-ISP Low-Light Processing

Sophisticated image processing suppresses noise while retaining colour, sharpness and motion detail when the lighting turns difficult.

Smart Hybrid Light

Infrared and white supplementary lighting deliver three operating modes, with an illumination range rated at up to 40 metres.

Motorised Varifocal Coverage

The horizontal field of view adjusts from roughly 102° down to 44°, letting you trade broad scene coverage for tighter detail on entrances, loading areas and perimeter zones.

Dual-Microphone Audio

An arrayed dual-microphone with environmental noise filtering captures clear mono audio, and line-level audio input and output are provided too.

Moderate Anti-Corrosion Protection

The Y version includes NEMA 4X anti-corrosion protection for sites with moderate corrosion demands, such as areas exposed to salt-laden air or acid rain. Note that Hikvision classifies this model as moderate protection rather than its highest marine-grade category.

Local and Network Recording

Recording options include microSD cards up to 512 GB, NAS storage and Auto Network Replenishment for resilient storage designs.

Frequently Asked Questions

What does the Y version indicate?

The Y version adds NEMA 4X anti-corrosion protection. Hikvision rates this model for moderate anti-corrosion requirements rather than its highest coastal or chemical-plant protection category.

Can the viewing angle be set remotely?

Yes. The motorised 2.7–13.5 mm varifocal lens can be driven remotely during installation to dial in the field of view precisely.

How does Smart Hybrid Light operate?

It brings infrared and white supplementary lighting together in a single camera, with three selectable lighting modes covering discreet monitoring, colour detail and event-triggered illumination needs.

Is audio supported?

Yes. The camera carries an arrayed dual-microphone with environmental noise filtering, along with line-level audio input and output interfaces.
