Video security as a service (VSaaS), Internet of Things (IoT), 4K ultra high definition (UHD), H.265 are the current primary trends in today's digital video technology. Hisilicon as the pioneer digital media system on chip (SoC) developer and manufacturer, the company recently launched Hi3519 SoC which supports 4K UHD video encoding with the latest H.265/HEVC compression. Although H.265/HEVC new compression technology greatly reduce the transmission bandwidth and storage capacity required for ultra high definition video, the application & deployment of H.265 technology is still in introduction stage. However, we expect the H.265 products will be popular, eventually replace the current H.264 standard to meet the growing demand of ultra high definition video products.
We are the network camera manufacturer, catching up the technology trend is crucial important to us. Before the unveil of Hi3519, Hisilicon launched the Hi3516D and Hi3516A. Many users must be familiar with Hi3516A, because it advocates up to 5 megapixel video encoding with H.265 format, additionally, supports panoramic lens correction. Well, Hi3516D is another digital media SoC for video surveillance application, it supports 3 megapixel video encoding with H.265 format. In this article, we intend to provide some basic information about network camera modules that based on Hisilicon Hi3516D SoC.
Hi3516D is a new generation SoC designed for professional HD IP camera. The Hi3516D is based on Cortex A7 architecture, it incorporates a new-generation image signal processing technology and adopts the latest H.265/HEVC video encoder, low-power consumption design. Hi3516D supports 90°or 270° rotation and lens distortion correction, which meets requirements in various surveillance applications. It also fully supports 3A algorithms, which allow customers to design different types of IP cameras including the IP AF zoom module. The Hi3516D integrates the POR, RTC, and audio CODEC and supports various sensor levels and clock outputs, which significantly reduces the EBOM costs for the Hi3516D HD IP camera.
3MP IP camera module adopts Hisilicon Hi3516D solution, embedded with Linux OS, standard 38*38 dimension, easy to fit into different camera housings, 2048x1520 resolution, H.265/H.264 encoding. It's quite suitable for low light applications, integrating with IR-CUT driver, sensor, encoder, transmission all-in-one, offering free ClientCMS, Smartphone App.
IMX185LQJ is a 1/2 type full HD CMOS image sensor for security cameras. Compared to other Sony Exmor CMOS image sensor, the IMX185 adopts newly developed 3.75 µm unit pixel technology to achieve high sensitivity and high signal-to-noise ratio (SNR). IMX185 CMOS image sensor is suitable for day/night camera, it improved infrared sensitivity approximately 1.8 times than other existing CMOS image sensors.
You may also find 4MP IP cameras that based on Omnivision OV4689 + Hi3516D solution. The 4MP IP camera module can deliver 4MP @ 15 fps or 3MP @ 30fps video stream, it supports H.265/H.364/MJPEG video encoding. Furthermore, it comes with audio I/O, alarm I/O, RS485, USB, BNC video output, microSDHC/TF card slot interfaces. This camera module can support motorized lens, complies ONVIF 2.4 standard. By the way, IMX291/290 + Hi3516D IP cameras are available in the market, IMX291/290 also supports ultra low light performance, meanwhile it supports super wide dynamic range.
Sony has developed the approx. 2.13M effective pixel back-illuminated CMOS image sensors IMX290LQR and IMX291LQR with improved sensitivity in the visible-light and near infrared light regions for industrial applications. A new 2.9 µm-square unit pixel has been developed that combines a back-illuminated structure with technology for improving near infrared sensitivity to further enhance picture quality at low illumination while at the same time realizing Full HD cameras for industrial applications. This realizes two or more times the sensitivity in the visible-light region and three or more times the sensitivity in the near infrared light region than that of the existing Sony product (IMX236LQJ). In addition, two types of WDR (Wide Dynamic Range) technology are also provided to further improve imaging performance. The new lineup includes the two types of the IMX290LQR, which has the DOL (Digital Overlap) -WDR function and the IMX291LQR, which does not have the DOL-WDR function.
