Overview

Hikvision DS-2CD6425G1-20 2MP Separated Network Camera
The Hikvision DS-2CD6425G1-20 is a 2MP separated network camera designed for reliable Full HD surveillance in applications where discreet camera installation and flexible positioning are important. It delivers 1920 x 1080 resolution with clear image quality, while the 2.8mm lens provides a wide viewing perspective for monitoring indoor and general security areas.

The camera supports efficient H.265 and H.264 video compression to help reduce bandwidth and storage requirements. Its 120 dB true WDR technology improves image quality in scenes with strong backlighting, while 3D DNR helps reduce image noise for cleaner and sharper video.

Description

This Hikvision 2MP network camera combines Full HD video, advanced image processing and flexible connectivity in a separated camera design. The 2 metre lens cable allows the camera lens to be positioned separately from the main camera body, making it suitable for installations where a compact or discreet viewing position is required.

Audio and alarm connections provide additional options for integrating the camera into a wider security system. A built-in memory card slot also supports local recording, while the RJ45 Ethernet connection provides network connectivity for video access and camera management.

Features

Clear 2MP Surveillance Imaging
The camera captures video at up to 1920 x 1080 resolution, providing detailed Full HD footage for everyday security monitoring. Backlight conditions are handled using 120 dB WDR, helping maintain usable detail in areas where bright and dark sections appear together.

Additional image processing includes:

• 120 dB true WDR for improved backlight performance
• 3D DNR for reduced image noise
• BLC and HLC for challenging lighting conditions
• Defog support for improved visibility in hazy conditions
• Support for one fixed region of interest (ROI)

Network and Recording Connectivity
The DS-2CD6425G1-20 uses a 10/100 Mbps self-adaptive RJ45 Ethernet port for network connectivity. Video compression supports both H.265 and H.264, helping optimise network traffic and storage usage.

A built-in memory card slot provides an option for local video storage, depending on the selected memory card and recording configuration. The camera can also support up to 15 simultaneous live viewing channels.

Audio and Alarm Integration
For installations requiring more than video surveillance, the camera includes dedicated audio and alarm interfaces. The available connections allow it to integrate with compatible security equipment and external devices.

• 1 x line-in audio input
• 1 x line-out audio output
• 1 x alarm input
• 1 x alarm output
• 1 x RS-485 interface
• Motion detection support

Separated Camera Design
One of the main advantages of this Hikvision camera is its separated design. The 2 metre lens cable allows the lens and camera body to be positioned independently, which can be useful for discreet installations, access control points, retail environments and other areas where the camera body needs to be positioned away from the viewing location.

The supplied model is the DS-2CD6425G1-20(2.8mm)2m(O-STD), fitted with a 2.8mm lens and a 2 metre lens cable.
