Introducing you the new AHD camera solution which can achieve 4 megapixel and 5 megapixel video surveillance. The new solution can bring you a higher level of image quality than HD/FHD solution, yet without increasing the cost. Intending to output image resolution higher than Full HD, the new solution adopts a complete new range of hardware design that consisting of high performance image processing processors and 4MP/5MP CMOS image sensors.
In order to compete with network solution, the analog technologies keep evolving and now the majority of analog technologies such as HDCVI, HD-TVI, AHD can capture 5-megapixel resolution video. Comparing the IP cameras, AHD and other analog technologies have advantages of transmitting uncompressed, lossless and zero latency video over coaxial cables, the transmission range can reach up to 500 meters. Hence it's the best solution if you'd like to upgrade your existing standard definition CCTV system to HD.
Nextchip is the original developer for AHD technology, intending to maintain the momentum of this technology, the company keeps releasing new ISPs to support higher image resolution data processing. Last year, the company launched the NVP2475 ISP which has the image processing capability that reaches up to 5-megapixel. By incorporating with OmniVision OV5658 CMOS image sensor, NVP2475+OV5658 AHD camera can deliver 5-megapixel analog video capturing performance.
OV4689 is a familiar 4-megapixel CMOS image sensor has been widely used in many video applications, except being adopted in IP video surveillance, it’s a popular sensor for car dashcam as it can provide excellent high dynamic range image. NVP is from NEXT CHIP COMPANY, it’s the latest image signal processor supports 4-megapixel image raw data input. This image signal processor support 2D/3D noise reduction, WDR and excellent low light performance.
