Dahua IPC-HDW4431EMN-AS-0280B 4MP IR Outdoor Turret IP Security Camera
Dahua's Pro series of cameras offers high-resolution on video and cutting-edge technology in a compact and accessible package. The cameras feature H.265 video compression, reducing bandwidth and storage requirements without sacrificing video quality. The camera series incorporates True Wide Dynamic Range, Smart IR, and the Intelligent Video Analysis, features typically found on high-end surveillance systems. This series provides a rugged enclosure rated to IP67 Ingress Protection on to protect your security investment.
Wide Dynamic Range: For application ons with both bright and low-light condition ons that change quickly, True WDR (120 dB) optimizes both the bright and dark areas of a scene at the same theme to provide usable video.
Intelligent Video System (IVS): IVS is a built-in video analytic algorithm that delivers intelligent functions to monitor a scene for Tripwire violations, intrusion detection, and abandoned or missing objects. A camera with IVS quickly and accurately responds to monitoring events in a specific area. In addition to scene analytics, the camera supports face detection to quickly capture a face and upload the image to a server. The camera also offers tamper detection by recognizing a dramatic scene change and generating a warning message to inspect the camera.
High Efficiency Video Coding (H.265): The H.265 (ITU-T VCEG) video compression standard offers double the data compression ratio at the same level of video quality, or substantially improved video quality at the same bit rate, as compared to older video compression technologies. H.265 offers such impressive compression by expanding the pattern comparison and difference-coding, improving motion vector prediction and motion region merging, and incorporating an additional filtering step called sample-adaptive off set filtering.

Security Camera Features
The fixed length or vari-focal length refers to the ability to adjust the camera’s field of view. The smaller the lens size, the wider the field of view. Fixed lenses will be fixed for the life of the camera but vari-focal lenses can be adjusted to have the best field of view. Vari-focal lenses are two kinds, manual and auto. If you choose manual vari-focal lense, you will need to hold the camera adjust the focal length where as if you choose motorized vari-focal lens, you will be able to perform the same task from your computer. That is the main difference.
