LiLin - AHD265AX4.2 - 5MP Day & Night Vari-Focal Dome Camera
Product Overview
The LILIN AHD265AX4.2 is a 5MP day/night vari-focal dome camera designed for analog HD surveillance systems. With a 5 megapixel CMOS image sensor, removable IR cut filter, high-efficiency IR LEDs up to 20m, and AHD coaxial transmission support, it provides detailed monitoring with reliable day and night performance.
Key Configuration
Model: LILIN AHD265AX4.2; camera type: day/night vari-focal dome camera; image sensor: 5 megapixel CMOS; IR range: up to 20m; video output: AHD 5MP or CVBS 960H; protocol: UTC function over AHD-Coaxial; transmission: coaxial cable.
Key Features
• 5 megapixel CMOS image sensor supports detailed surveillance capture.
• Day/night operation with removable IR cut filter supports 24-hour monitoring.
• High-efficiency IR LEDs provide night visibility up to 20m.
• DWDR and 2D noise reduction help improve image quality in challenging scenes.
• AHD 5MP or CVBS 960H output supports compatibility with analog surveillance systems.
Technical Context
The AHD265AX4.2 supports video transmission over coaxial cable and is designed for seamless compatibility with standard analog equipment. Its AHD-Coaxial UTC function allows compatible systems to control supported camera settings over the video line.
Installation Notes
Use with compatible AHD 5MP or CVBS 960H recording equipment. During installation, position the dome for the required coverage, verify IR illumination at night, and confirm coaxial cable transmission quality for the monitoring distance.
