Guru Mini Camera: High Def High Yield does not mean

Contemporary systems security camera already using the technology digital and makes these devices are digital image sensors behind the camera lens element in the mini-camera that radically changes light and the image captured through the lens of your camera and converts them into digital signals. These signals are stored in internal memory the device or sent without delay to a video file a digital computer or a digital recorder.

Costs of mini digital cameras declined, mainly because of the media image sensors are much easier to produce today than some years ago. These sensors convert light into electrons and there are two main technologies for chips used to make these sensors: CCD or Charge-Coupled Device and CMOS sensors or free metal-oxide semiconductor image. CMOS chips are easier to produce and therefore are more expensive than their CCD.

These technologies grown significantly in modern times that electronic cameras can now capture and produce images of high definition video high with image quality and resolutions. As an online retailer or distributor devices mini camera, you can get an idea of demonstrations of these technologies to maintain a balance between obtaining high-definition products and provide customers what they want. HD cameras sold at higher prices does not necessarily mean a better return on their investment in many stores ultimately know.

Understand Technology Mini Digital Camera

The following briefly describes the most common technologies and well-liked in force in digital cameras when all points of sale in line must know system security.

* Chips CCD

Most electronic devices used today CCD technology. CCD were the result of research at low cost and easy to produce product solutions that eventually need to replace the two mechanized screens and use of film cameras. In layman's terms, the electronic version of the CCD eyes.

There are 4 types CCD: Linear, Interline, full screen and the camera frame transfer CCD. Linear CCD use a single line of pixels and other features moving pixel sensors physically. Are now rare, except in flatbed scanners. Interline CCDs are much more commonly used because of its higher cost high and the restrictions on full-frame transfer CCD shot.

* CMOS sensor chips

CMOS has emerged as an alternative easier to manufacture CCD, because it uses the same manufacturing processes used for semiconductors become worldwide, making them less expensive the CCD. In addition, CMOS sensors consume less power than CCD, but with additional features such as the conversion process from analog to digital the white balance settings, processing charge signals and other camera controls.

* Chips Interline CCD

Interline CCD chips have a configuration that includes a composite array and masked photosensitive intertwined, giving them a better electronic functions of formwork are the principal executives of non-transfer CCD. Also leakage of electrons that prohibits overflow of electrons is the main cause of the overexposure of pixels on the opposite diagonal, which makes the effect on the flowers or spots in images and video.

* Super HAD CCD chip

Almost all cameras Sony CCD on the market now use their brand Super HAD (Hole Accumulation-Diode) CCD sensor chip that offers improved sensitivity and the rejection rate of smear types standard CCD. It uses a technology semiconductor Sony developed new multinational two microlenses are placed above each photodiode can activate the sensor to collect more photons of incident light.

Chip sensor technology and image resolution

Selection the mini camera sensor chip technologies that provide the best solution will depend on the exact and the environment of these cameras will be used. Although structurally speaking, CCD cameras have greater sensitivity to light and higher resolution which makes them ideal for use with photographs of high quality. For low light applications interline CCD working well, especially if used with the improvement of IR light, even if it still works well at other levels of light.

CMOS cameras have rather low resolution and lower sensitivity making excellent for the cameras costs lower level, despite the fact that the latest versions on the market are advertised to have the qualities that can approach that of CCD. However CMOS cameras work best when light is infallible, and in the corridors of office. The chip is sensitive to light Infrared does not work better in bright sunlight. It is also less sensitive to light little trouble using them outside at night.

The Sony Super HAD to provide the best quality in terms of improved sensitivity of smear and the rejection is advantageous for use in any location and conditions, whether or not it is night or day, clear or cloudy, and dark or light. However, these cameras bring a higher price segment standard CCD sensors.

High or lower price?

CCD would have higher prices than making CMOS counterparts to use premium, while CMOS is suitable for use in initial and mid-level. However, CMOS chips consume less power than CCD and CMOS camera therefore lasts longer on batteries for an important mobile applications and wireless mini security camera.

Sony Super HAD CCD cameras have a higher cost compared to the interline CCD standard. For example, a mini-camera that uses a Sony CCD cost about spacing $ 93, while a similar camera that uses a chip from Sony Super HAD CCD will be valued at over $ 117. It has however in the evolution of CMOS technology, making them roughly the same size CCD as he has, but lower prices.

But what some people prefer for their safety? A high-resolution camera that will sell thousands dollars, or a mini-camera with lower resolutions, but will available at very reasonable prices? Again, the answer depends on what the customer wants or the environment where the cameras would be applicable. Some prefer high sensitivity cameras and lighting specifications when used in places as intense as it was night. On the other hand, other applications that do not really need a video output high D would do well with less expensive cameras.

As a distributor of safety is very important that you understand what customers want and respond to their products to meet these needs. Do not be profitable to store higher price mini cameras high definition (which should offer higher margins) – If your clients prefer cheaper solutions.

What difference does the HD cable for the Wii do?

I have a new HDTV and you can hear buy a cable high definition so you can make better graphics? Is it worth buying?

No. I say more? .. Well, yes I'm bored so I will. No, the Wii's graphics card is horrible for the current generation systems. You will not see much improvement in all plots. If the Xbox was talking about. It would be worth the purchase, taking into account the power of the CPU and graphics cards Xbox, it would benefit. But since the Wii .. No, not really. For me, it seems that you are looking for something with the graphics …. Get an Xbox or PS3. A cable will not really change. Sorry, but do not lose not $ 25 on it. It's just a ploy by Nintendo to make the purchase. If you wait, they were, would be sent to Wii with cable and high definition. Anyway, Goodluck.
