China Security Exhibition Reuters for gun camera , the reason is called gun-type , only for the appearance , the internal configuration and quality are very different . Gun Camera surveillance camera gun main requirements : Suitable for light is not sufficient area and night lighting equipment can not be installed in areas in the scene only to monitor the position or move when the optional gun -type camera . With the development of the market, gun camera product positioning more clearly , with key components are constantly upgrading products in the peaceful city of applications are gradually increasing.
IP Camera Gun increasingly clear product positioning
First, we see IP network camera through the gun after five years of development , the image resolution solution clarity , the megapixels HD HD200 square with 300,500 square or 8,000,000 pixels UltraHD Ultra HD has been the product on the development trend of chasing the high , but it all suddenly changed in the middle of this year .
From participating in IP Network HD Box Camera test products never see past appeared 5,000,000 , 8,000,000 pixel high solution clarity of IP network cameras, and IP network flaunt million pixels camera even disappear from the market is not real-time monitoring complex goodbye. This illustrates the fact that a development is reasonable and practical IP network camera with clear positioning condition gradually appear.
Thus , we see 1.3 million , 200 and 3,000,000 pixel IP network cameras such has been active in the security surveillance applications , but also because in the compression chip performance has stabilized with the requirements and standardization , video and image processing components in determining IP has a decisive influence on the formation of the key specifications of network cameras , so smooth and the image quality is no longer a priority dilemma HD high Definition is facing challenges, but also highlights the key components has resulted in IP network camera with practicality and began to market the product Location -based direction.
With the upgrade key components
wansview IP camera
products tested from around the brand, it is interesting that on the IP network camera key component in the mix , we can find on the photosensitive components and chips and video compression rates core chip , the emergence of a small rule group performance with distinction , we will match these components to make a chip roughly aligned instructions, and then to analyze the performance of these Sensor from ISP and compression SoC chip plus after show , from those presented in comparison to the use of combinations of different components webcams performance , so look out for in the IP network cameras in the past and present differences in component selection and such a result for the overall positioning of the impact of IP network cameras , and now we will look at several ways to participate in the competitions in the mix of components .
1, Sony1/2.8 "ProgressCMOS ISP Hi-3516 portfolio
With this combination is accounted for the majority of participating in competitions in a way that can be seen from the inside is Sensor 1080P @ 30fps conditions , with Hass SoCARMCortexA9800MHz in performance , the only way to get a different IP network camera brands have different parts of the difference ISP leaving this section, it is perhaps the bag into the SoC ISP to host , or in conjunction Nextchip independent ISP chip , but no matter what kind of way , ISP performance will dominate the difference in this way . So perhaps there is the strengthening and wide dynamic backlight and front-end intelligence on the part of the difference, look at the network camera manufacturer in the SDK through skill development on the integration of components .
2, Sony1/2.8 "ExmorCMOS or 1/3" AptinaCMOS ISP DM368 portfolio
It basically looks like a combination of cost and functionality from the mediocre is a more reasonable combination , but it does not necessarily mean that it is a reasonable quality and performance in the extreme. From here to see the Sensor should not be using 120fpshighframe the IMX136 or lower some of 60fpsIMX-140, because the effectiveness of compression chip does not support HighFrame, but lower 30fpsIMX-122 to match TIDM368ARM9432-MHzSoC, this mix created by the difference will be presented in a different performance image itself will be essentially Sensor , which is easily accessible from IP cameras in quality and a wide dynamic performance up to distinguish it.
3, Sony1/2.8 "ExmorCMOS ISP GM-8128 portfolio
The third has two different Sensor combination with , one SonyIMX-136, First, IMX-036, although under natural conditions appears to be similar from a combination of components , but 3,000,000 and 2,000,000 (1080P) of ExmorCMOS abruptly there is a different number of sheets with 120fps and 30fps video performance , unable to determine if the conditions in the real component can provide it, literally in a simple combination of components for engineering companies or users are unable to tell the difference from the basic specifications of the camera , and only such a combination provides an output corresponding 1080P @ 30fps rising step in the GM SoC, high resolution performance and therefore From this combination of components such as are provided within the certain limits .
4, Sony1/2.8 "ExmorCMOS or 1/3" AptinaCMOS ISP AmbarellaA5s
This last combination in addition to the performance of key Sensor is to determine the merits of the image outside , ISP and Ambarella Ambarella compression chips is also one of the determinants of final decisions IP network camera performance , it seems from this combination of compression chip also limits front Sensor 30 or 60fps frame number conditions, then a high number of sheets Sensor can only offer this combination of components smoother picture conditions, while the cost of this combination in a variety of combinations of conditions is perhaps the most competitive way.
In summary , IP network cameras should be considered in its sixth generation production stage, most of the components are based on the original CCD technology development technology , and demand for security applications must be optimized , full application of the new generation of CMOS technology professionals , and enhance the ability to inhibit the processing of the image processing and high resolution digital noise . At the same time while also greatly enhance image data read speed of light-sensitive components by increasing the amount of light surface micro- lens forward, let IP network cameras on stage to enhance the sensitivity doubled compared to the previous generation of products !
Safe City Project Application
With the development of society as a whole , in order to further meet the high standards of social and economic development and the people of civilized life , to create a safe , comfortable, warm and efficient living environment, safe city construction of a city created a high-definition video surveillance system the system according to the needs of different environments , choose different types of high-definition products to achieve a wide range of details of site observation and close monitoring , and video evidence by matching the video storage device . The project uses the DH-IPC-F728WP this HD network camera UOB shares , and this camera in some important traffic junctions and some of the densely populated area. In the construction of this peaceful city , this high-definition network camera UOB shares with its unique performance advantages by the users of high praise. While high-definition video surveillance to promote decency in peace building in the city is also greatly improved the effectiveness of video surveillance monitoring system to further enhance the effectiveness of video capture card .
Safe City is to build a city building high-definition video management system to achieve the city's security monitoring and management, and the front-end HD equipment we used the DH-IPC-F728WP The 2 million HD Box Network UOB shares camera , this machine has reached 2 million pixel resolution , the image is clear , very clear picture monitored able to identify license plates and figures detail, while color reproduction performance of this machine is also very good , no color cast phenomenon. We installed this machine is mainly used in large venues, transport routes , bus stations, railway stations and other important places densely populated . This batch of results after installing the machine from the procurement has been good and runs very stable , is a good product.
