Overview:

The Hikvision 4MP Dual Light MD Varifocal Dome Network Camera is designed for reliable indoor and outdoor surveillance where clear imaging, flexible viewing angles and intelligent detection are important. It combines 4MP image quality with a motorized 2.8 to 12 mm varifocal lens, Smart Hybrid Light technology, 120 dB WDR and human and vehicle detection. The camera also provides onboard recording support, two-way audio connectivity, alarm interfaces and durable IP67 and IK08 protection for demanding security installations.

Description
The Hikvision DS-2CD2741G0-LIZSU is a 4MP varifocal dome IP camera built for professional security monitoring. Its motorized 2.8 to 12 mm lens makes it easier to adjust the viewing angle during installation, allowing the camera to be positioned for closer or wider coverage without replacing the lens. Smart Hybrid Light combines infrared and white light illumination to provide clearer monitoring in low-light conditions, with supplementary lighting reaching up to 30 metres.

Human and vehicle detection helps improve motion monitoring by distinguishing relevant subjects from general movement. The 120 dB true WDR technology also helps maintain usable image detail when scenes contain strong backlighting, while 3D DNR reduces image noise in challenging lighting conditions.

Features:

4MP Hikvision Varifocal Dome Camera
With a maximum resolution of 2560 x 1440, the camera delivers detailed video for residential, commercial and industrial surveillance. The 2.8 to 12 mm motorized varifocal lens provides flexibility when setting the desired field of view, making the camera suitable for different installation distances and monitoring requirements.

Key imaging and monitoring capabilities include:

• 4MP image resolution up to 2560 x 1440
• 2.8 to 12 mm motorized varifocal lens
• Smart Hybrid Light with infrared and white light illumination
• Supplementary light range of up to 30 m
• 120 dB true WDR for challenging backlit scenes
• BLC, HLC and 3D DNR image enhancement
• One fixed region of interest (ROI)
• Human and vehicle motion detection
• Up to 6 simultaneous live view channels

Smart Hybrid Light for Day and Night Security
The integrated Smart Hybrid Light system provides additional illumination when required, helping the camera maintain useful visibility after dark. Infrared and white light can support different surveillance conditions, while the combination of intelligent detection and low-light imaging helps provide more practical monitoring around entrances, driveways, commercial premises and other security-sensitive areas.

Efficient H.265+ Video Compression
The camera supports H.265+, H.265, H.264+ and H.264 video compression. H.265+ can reduce bandwidth and storage requirements compared with older compression methods, making it useful for systems where network capacity and recording storage need to be managed efficiently.

A built-in memory card slot supports storage capacities of up to 512 GB, providing an additional recording option without requiring all footage to be stored on a central recorder.

Audio and Alarm Connectivity
A built-in microphone allows the camera to capture audio for additional security monitoring. The camera also provides audio input and output connections, along with alarm input and output interfaces for integration with compatible security equipment.

The network connection is provided through a 10M/100M self-adaptive RJ45 Ethernet port, supporting straightforward integration with an IP surveillance network.

Durable Dome Design for Indoor and Outdoor Use
The Hikvision dome housing is designed to withstand demanding installation environments. IP67 protection helps protect the camera against dust and water, while IK08 vandal resistance provides additional protection against physical impact. This makes the camera suitable for a range of indoor and outdoor security applications.
