2013-01-15 10:46:04 - more and more new technologyapplications have been used in the field of analog surveillance camera industry ,and the development of it .
Nearly two years in the area of surveillance camera, network camera, high-definition video camera has become the hottest topic in the industry, but in the foreseeable future within a few years, analog camera will continue to occupy an important market share. For general civilian needs, conventional IR analog camera with the advantage of widely applicable spaces, low price, convenient for installation and maintenance, etc., will remain the first choice for the majority of ordinary users. Therefore remaining the focus on conventional infrared camera has its practical significance, this paper attempts to do some analysis on the development of related technologies and applications in the past year.
SONY program upgrade
Sony has launched the Effio-E650 line program for three years, but in the
early period due to the technology was not mature and the price was too high, plus the larger of its DSP chip BGA great processing difficulty, and the program had high requirements on the overall circuit design , so seldom manufacturers adopted the program at the beginning of the first two years . With the improvement of the maturity of the program, the prices continued to drop, as well as the strengthening of various manufacturers to its related technical mastery , in the mid-2011 when the SONY3172 chip shortage came out, most CCD board camera manufacturers began to aggressively promote Effio-E program. Due to its higher screen resolution, color reproduction and a higher signal-to-noise ratio, Effio-E program was quickly recognized by the market; SONY Effio-E program launched an enhanced version at the end of 2011. To the current terms of material costs alone, there has no price difference between it and SONY3172 program , but the Effio-E program CCD board often sales in slightly higher price because its BGA process lead to high maintenance costs of its repair.
In addition to Effio-E program, Sony had additional launch of digital wide dynamic Effio-S program, with a real wide dynamic function Effio-P dual-scanning program, and also had gotten a different promotion. On the CCD, Sony has recently released the 811CCD to replace 673 , and will have an ongoing improvement on the series of programs .
Note: BGA is an abbreviation of “Ball Grid Array Package” , that’s the spherical pin grid array packaging technology. It changes the tradition J-shaped or wing footing leads from around to pin of the original chip into the spherical plane leads from the bottom of the chip, which makes the chip body under the belly bottom become the whole plane grille pin array. Its main advantage is that when there are a lot of pins, it can increase the distance between pins and to improve the yield of chip processing; Furthermore ,the signal delay is reduced, the frequency adaptation is greatly improved.
