It enhances monitoring efficiency. At the same time, the cameras can support face detection, and can quickly capture a face and upload the image to the server, ideal for business intelligence, and Facial Detection, for searching or identification of individuals.
It provides ultra-high-definition, smooth and stable video effects for users. The system realize storage, transmission, positioning, intercom and other functions, which assist user units in daily visual inspection, mobile law enforcement monitoring, emergency command and dispatch, and intelligent application of safe production and other business management.

beard and expressions (anger, sadness, disgust, fear, surprise, calm,
happiness, and confusion). It also supports face cutout settings: Face,and single inch photo. Three snapshot methods are also featured:Real-time snapshot, priority snapshot, and quality priority.    


BLC and HLC digitally adjust to compensate for uneven illumination    

By enabling BLC, you are telling your camera to overexpose the brighter parts of the image in order to properly expose the darker parts.
Highlight Compensation (HLC) is a setting that allows your camera to compensate for the brighter parts of an image, preserving detail in the brighter parts of the image that would otherwise be blown away.
You may find yourself with very bright lights in your camera's field of view, causing parts of the image to blow up. Think of the headlights of a car that shines on your camera. When the camera is correctly exposing your scene, bright headlights can cause the image to be overexposed, resulting in a loss of information.
To adjust the compensation of the VD-SD4825X camera, please log in to the web interface. From here, navigate to Settings > Image > Image > Exposure Settings.    


WDR can observe any detail of the image 

 Wide Dynamic Range (WDR) uses two image sensors to capture the same scene at two different exposures. WDR sensors produce images that are properly exposed in the darker and brighter parts of the image, providing more detail in a wider dynamic range between shadows and highlights.
You can set WDR to On, Off, or Auto. When set to Auto, the WDR setting will turn itself on and off as needed. This is ideal for uneven lighting only at certain times of the day. For example, you have east-facing windows, you really only need WDR in the morning when the sun is pouring into the room.
You can also adjust the strength of WDR if it is on or set to automatic. The higher the value, the less contrast between dark and light images. Adjust this setting carefully, as the higher the WDR, the lower quality pictures your camera will produce.    


3DNR Enhanced Clarity in Low-Light Situations    

3DNR can improve image denoising performance with predictive detail preservation and enhancement, enabling cameras to capture clearer, sharper image quality in still image areas. Additionally, it is capable of capturing sharper image quality for moving objects and extremely low light conditions.    


Cutting-Edge H.265 Video Compression    

An advanced compression codec like H.265 results in a lower bitrate and less need for storage.
