  潍坊保安公司加盟教你选购摄像头
  Weifang Security Company joins us to teach you how to choose cameras一、 首先要看看感光材料
  First, we need to look at photosensitive materials.
  普通市场上的感光材料可以分成两样:CCD(电荷耦合)与CMOS(金属氧化物)。前一种的优点是成像像素高,明晰度高,颜色恢复系数高,常常应用在高层次数码摄像机、数码照相机中,缺陷是价钱比拟贵重,耗功较大。后者缺陷正好和前者互普,价钱相对低价,耗功也较小,可是,在成像方面要差一些。
  Photosensitive materials on the general market can be divided into two kinds: CCD (charge coupled) and CMOS (metal oxide). The former has the advantages of high image pixels, high clarity and high color recovery coefficient. It is often used in high-level digital cameras and digital cameras. The disadvantage of the former is that it costs more and consumes more power. The defect of the latter is just the same as that of the former. The price is relatively low and the power consumption is small. However, it is worse in imaging.
  二、 像素也是一个关键目的
  2. Pixel is also a key purpose
  如今市面上主流产品像素普通在35万左右,早些时分也出了一些10万左右像素的产品,由于技艺含量相对较低效果不是很好,不久就退出历史舞台了。这个时分或许有人会问,那是不是像素越高越好呢?从普通视点说是的。可是从另一个方面来看也就不是那么了,关于同一个画面来说,像素高的产品他的解析图象才干就更高,那么你所需求的存储器的容量就要很大了。
  Nowadays, the mainstream products on the market usually have about 350,000 pixels, and some products with about 100,000 pixels were also produced earlier. Because of the relatively low technical content, the effect is not very good, it soon withdrew from the stage of history. At this time, some people may ask, is that the higher the pixel, the better? From a general point of view, yes. But on the other hand, that's not the case. For the same picture, the product with high pixels has a higher ability to analyze the image, so you need a lot of memory capacity.
  三、 分辨率是潍坊保安公司谈的比拟多的问题我想我没有必要到这儿说分辨率这个东东了,我们较理解的应该就是:
  3. Resolution is a problem that Weifang Security Company talks more about. I don't think I need to come here to talk about resolution. What we understand most is that:
  A:你的显现器什么什么的。分辨率可以上到多高,刷新率呢?
  A: What brand is your display? How high is the resolution and refresh rate?
  B:呵呵,还好了,我产用在1024*768 ,设计的时分就用在1280*1024。玩游戏普通就800*600了。
  B: Oh, good. I used 1024 * 768 for production and 1280 * 1024 for design. Playing games is usually 800*600.
  可是摄像头的分辨率可不彻底同等于显现器,切切的说,摄像头分辨率就是摄像头解析图象的才干。如今市面上较多的CMOS的普通在640*480,有是也会在800*600。可是假如是CCD的普通还要高些。
  But the resolution of the camera is not exactly the same as that of the display device. To be precise, the resolution of the camera is the ability of the camera to analyze images. Nowadays, the more CMOS on the market is 640*480, and some will be 800*600. But if it's a common CCD, it's higher.

  四、 是摄像头,当然也要比拟摄像的效果
  Fourth, the camera, of course, should also compare the effect of the camera.
  摄像头的视频捕获才干是用户较关怀的了,如今电脑摄像头所可以捕捉都是经过软件来完成的,因而对电脑请求比拟高,普通状况下640*480他的速度可以抵达30帧/S,但当分辨率在320*240的状态下,速度稍微一快点。因而,本人在选购是,可以按照本人的效果选择一个适宜本人的。
  Video capture ability of the camera is the most concerned of the users. Now the capturing ability of the computer camera is accomplished by software, so the request of the computer is relatively high. Under normal conditions, 640*480 can reach 30 frames/S, but when the resolution is 320*240, the speed is slightly faster. Therefore, I can choose a suitable one according to my effect when I choose to buy.
  五、 镜头是一个大问题
  V. Lens are a big problem
  估量这么东东许多用户在购置的时分会无视掉,但这却是摄像头对光线的较重要部位。光圈的大小、镜头可调焦的范围等等。普通按照材料分主要有3中,有玻璃镜片;朔胶镜片和化合物的,这儿较好的要算是玻璃的,他的通光系数大,普通好的镜头他的通光口径也会做的较大,在光线不是很好的时分也可以得到交好的效果,可是价钱要高点(一分钱一分货)。朔胶的通光要差点,可是价钱廉价,就这点也得到了一些中低端用户的认可。化合物的市面上不是许多,这儿就不做详细引见了。
  It is estimated that many users will ignore it when purchasing, but this is the most important part of the camera's light. The size of the aperture, the focus range of the lens, and so on. Ordinary according to the material points are mainly 3, there are glass lenses; plastic lenses and compounds, here the best is glass, his pass coefficient is large, ordinary good lens, his pass aperture will do larger, when the light is not very good, can also get good results, but the price is higher (a penny a penny a penny). The transparency of the plastic is almost the same, but the price is cheap, which has also been recognized by some middle and low-end users. There aren't many compounds on the market, so I won't give you a detailed introduction here.
  六、 其他数据
  VI. Other Data
  虽然说,如今的应用程序比拟多,本人也比拟好找,可是一个名牌产品,他里面的东西都很到位,普通会有摄影、摄像、印象文件管理、设置,有的摄像头带有MIR功用,那么软件方面还需求有音频方面的设置。
  Although today's applications are comparable, I am also comparable to find, but a brand-name product, his contents are in place, usually there will be photography, camera, impression file management, settings, some cameras with MIR function, then the software also needs audio settings.
  再来看看接口方面,曾经的摄像头都是选用并口,可是随着技艺的行进,慢慢的被USB的接口给替代了,这儿潍坊保安公司千万提示你一点,不要为了一点小利而放弃了USB接口的产品。终究并口快退出历史舞台了。
  Look at the interface, the camera used to use parallel ports, but with the progress of technology, gradually replaced by the USB interface, here Weifang Security Company must remind you a little, do not give up the USB interface products for a small profit. Eventually, they are about to quit the stage of history.
