> 4-MP 1/1.8" CMOS image sensor, low luminance, and high definition image. 

> Outputs max. 4 MP (2688 × 1520)@50/60 fps. 

> Built-in IR LED, and the max. illumination distance is 40 m. 

> Time-Division Exposure technology ensures that when the device is taking multiple snapshots of more than one targets, the quality of the snapshots will not be affected. It can also be used to adjust the brightness, speed and more of targets, to produce high quality snapshots. 

> ROI, flexible coding, applicable to various bandwidth and storage environments. 

> Two intelligent functions can be enabled at the same time, such as face recognition+people counting, face detection+people counting and PPE Detection+IVS. 

> With deep learning algorithm, it supports: face recognition, face detection, IVS, people counting, video metadata, PPE Detection, parking space management and ANPR, etc. 

> Privacy Protection: Mosaics can be automatically placed over the face or body of a person to protect their privacy. 

> Built-in Hi-Fi large-diameter speaker covers an auditory range of 20 meters. 

> Sound Management: With its built-in dual MICs and Dahua noise reduction algorithms, the camera supports the sound management function, using it to collect vocals, adaptively reduce noise, and filter non-human voices. 

> Alarm: 3 in, 2 out; audio: 1 in, 1 out; RS-485; BNC; supports max. 512 G Micro SD card. 

> Built-in dual MICs; 1-ch speaker; support two-way talk. 

> 12 VDC/24VAC/PoE+ (802.3at)/ePoE power supply, 12 VDC power output, max. current 165 mA and peak current is 700 mA, easy for installation. 

> IP67 and IK10 protection, Anti-Corrosion coating (optional).
