Analysis of high-definition IP Camera solutions

Analysis of high-definition IP Camera solutions
In recent years , network camera continue to impact the market, as the market increasingly high demand , there is a growing concern for high-definition network camera solutions , Texas Instruments (TI), Hass (HiSilicon), Ambarella (Ambarella), NXP Philips (NXP), l step (GrainMedia), Nextchip What are the characteristics in the end , the following small series will take you under them.
Currently on the market there are basically high-definition IP Camera solution three architectures :
The first category is the use of high-end camera modules ( movement, such as ACUTE the PE1005, SONY 's H11) as the image capture device , supporting an ASIC or DSP for encoding and transmission, such programs is relatively high , the use of professional imaging module , the original image is good, so the whole effect is very IPC products depends largely on the effect of supporting compression and transmission module , the main indicator is the compressed image clarity and timeliness , generally , a high-end program uses this architecture ;
The second category is the use of high-end camera module as part of image acquisition , and then supporting an ASIC or DSP for encoding and transmission, such analogies are operational and the first part of more such lenses can freely mix your own , you can also customize some special features to the product value. Imaging effect of such programs is very good, in the back-end compression and transmission is also not too many requirements. Very suitable mastered the network compression and transmission technologies are required but the effect on the image of the vendors use .
The third category is the use of CMOS sensor (SENSOR) as the image acquisition device , supporting the provision of ISP SOC chip , such programs have significant cost advantages , the main effect of such programs depends on the imaging chip maker Integrated ISP ( such as 3A, wide dynamic , etc. ) effects ; there is a more obvious advantage of such programs is relatively flexible and can be customized according to the characteristics of programs , such as capture, oversized low frame rate video.
For high-definition network camera , the network protocol and the SDK is a very important aspect , each company has its own network protocol and SDK, and basically dedicated exclusively . That each network camera are incompatible , not interchangeable , if we adopt the way outsourcing module is a big trouble in this regard , including system integration, customer care , and this will bring a big problem. HD IP Camera combines the core of the current security industry 's most cutting-edge technologies and applications : networking, HD and intelligent , but also the integration of the necessary conditions.
1 Based Module + SOC (DSP) application program
Currently advantage of such programs is the image effect is good , generally comes with the lens. Network compression module now supports 1080P TI's current main DM6467 and DM368, Maxim 's MG3500, Fullhan microelectronics FH8735, Fujitsu MB86H56, NXP 's PNX1005, Hass 's Hi3516/20 so on. DSP-based architecture which do have intelligent analysis DM6467 and PNX1005 , etc., each have their own advantages and disadvantages. Where TI is the leader in this industry , so TI is also relatively high. The advantage of such programs is the image better, difficult to develop relatively small drawback is that the lens curing , not according to their own requirements using the lens , which is developing and supporting the freedom of small projects , is the first choice for high-end customers .
2 Based BoardCamera + SOC (DSP) application program
Such programs appear on the market today there are more and Hass Hi3516 TI , etc., this program will fit mastered the network compression and transmission technology and relatively high demand for image used by customers and isp front sensor has been integrated , color reduction and low-light areas such indicators are handled very excellent example Division I PE0003 module very well and DM368, HI3616 programs such cooperation. Customer-proven , image effect is very good . Excellent image quality of such programs , developing large degree of freedom , based on customer requirements, characteristics to be customized and optional lenses.
3 Based SENSOR + SOC (DSP) application program
Such programs appear on the market today there are more and Ambarella TI , and also the current HD machines largest shipments , the market price is very confusing, there are ridiculously low low , high and surprisingly high . The advantage of such programs is low cost development is easy, and it's basically a fight can be used ; drawback is that the image quality is not good with the module or modules ( depending on the chip provided by ISP).
