HK-311331184 specification sheet

Overview:

The Hikvision DS-2CD2646G2H-IZS is a 4MP motorized varifocal bullet network camera designed for reliable security monitoring in challenging lighting conditions. Powered by DarkFighter technology, it delivers clear images in low-light environments, while 120 dB WDR helps maintain detail when scenes contain strong backlighting. The 2.8-12 mm motorized varifocal lens also makes it easier to adjust the viewing angle and focus during installation.

Description:

This Hikvision 4MP IP bullet camera combines high-resolution imaging, intelligent video functions and durable outdoor protection in a practical surveillance design. Its motorized 2.8-12 mm varifocal lens provides flexible coverage for different monitoring distances, while IR illumination up to 60 m supports visibility at night.

The camera uses H.265+ compression to reduce bandwidth and storage requirements without sacrificing useful image quality. Deep learning technology supports human and vehicle classification, with additional functions such as face capture, perimeter protection and motion detection for more effective security monitoring.

With an IP67-rated housing for water and dust resistance and IK10 vandal resistance, the DS-2CD2646G2H-IZS is suitable for demanding indoor and outdoor surveillance installations.

Features:

Clear Imaging in Difficult Lighting
The 4MP sensor provides a maximum resolution of 2688 x 1520 for detailed surveillance footage. Hikvision DarkFighter technology improves performance in low-light environments, while 120 dB WDR helps balance bright and dark areas in scenes affected by strong backlighting.

Additional image processing includes BLC, HLC and 3D DNR to help produce clearer and more usable video in changing lighting conditions.

Motorized Varifocal Lens
The built-in 2.8-12 mm motorized varifocal lens provides flexibility when setting up the camera. The focal length can be adjusted to achieve the required viewing area and monitoring distance, making it suitable for a variety of security applications.

IR illumination extends up to 60 m, providing additional support for nighttime surveillance.

Intelligent Security Monitoring
Deep learning-based human and vehicle classification helps improve detection accuracy and reduce unwanted alerts. The camera also supports several intelligent surveillance functions for more comprehensive monitoring.

• Face capture
• Perimeter protection
• Motion detection
• Human and vehicle classification
• 1 fixed region of interest (ROI)
• Up to 6 simultaneous live views

Network and Recording Connectivity
The camera includes a 10M/100M self-adaptive RJ45 Ethernet port for network connectivity and supports multiple video compression formats, including H.265, H.264, H.264+ and H.265+. H.265+ can help reduce storage and network bandwidth requirements compared with traditional compression methods.

A built-in memory card slot provides local recording capability, while audio and alarm interfaces allow the camera to integrate with compatible security systems.

• 1 x RJ45 10M/100M self-adaptive Ethernet port
• Built-in memory card slot
• 1 x line-in audio input
• 1 x line-out audio output
• 1 x alarm input and 1 x alarm output
• H.265 / H.264 / H.264+ / H.265+ video compression

Built for Outdoor Security
The rugged bullet housing is designed for use in demanding environments. IP67 protection helps guard against water and dust, while IK10 vandal resistance provides added physical protection for installations where the camera may be exposed to impact.

Model and Part Number
The camera model is DS-2CD2646G2H-IZS(2.8-12mm)(eF)(O-STD), with the part number / SKU listed as HK-311331184 . This makes it easier to identify the exact Hikvision camera when ordering, quoting or planning a replacement.
