The NS4025VB58 is a high-end IP camera to deliver video streams with 4MP (2592x1520), 3MP (2048x1520), 1080P (1920x1080) resolution. This camera is based on OmniVision OV4689 1/3-type 4MP progressive CMOS image sensor and Hi3516D/A codec engine hardware design.
It's able to capture vivid color and clear images in the daytime and at night. Included special 3 pcs IR array LEDs to provide Infrared night vision, the coverage can reach up to 165ft.
Thanks to its Hi3516D SoC, this camera offers 2D-DNR, Mirror, HLC, Lens Distortion Correction, Corridor mode (90°, 270° rotation), Flip, Motion detection, Privacy Mask, ROI encoding, Smart detection etc functions.
The camera is equipped with manual vari-focal 2.8-12mm standard lens, offering viewing angle from 106° to 28°. The camera can be equipped with a 2.8-12mm Motorized Zoom Lens which enable camera to automatically adjust the focal length intending to obtain clear view.
Based on Hisilicon SoC architecture, the NS4025VB58 supports H.264 and H.265 video encoding standard. Utilizing the H.265 compression, the data stream is reduced to 50%, so that the camera can save 50% network bandwidth and video storage space. Additionally, it adopts patented self-adaptive bandwidth technology, perfectly solving the network congestion or images with poor quality. So that this camera can automatically adjust the video bit-rate to flexibly adapt to the changes of network bandwidth. This helps to achieve the best image quality and the most efficient video transmission.
