How to choose the webcam?
|/img >/img src="//images/stories/tip/comp-progs/webcam-choice-1.jpg" alt="How to choose the webcam?" align=left title="Как выбрать веб-камеру?" /> Once opportunity to communicate with the interlocutor "alive", despite thousands and thousands of kilometers of distance seemed fantastic. Thanks to webcams the fantasy became reality. Now, even being on different continents, people can communicate, literally looking in eyes each other.|
Without webcam it is difficult to imagine the modern Internet and communications. Videoconferences, "live" broadcastings from around the world, an astrografiya – these and still give a set of other opportunities to the owners of the webcam. It was necessary only to choose that from them which will satisfy to your requirements.
Choosing the webcam, it is necessary to decide on the purchase purpose. Whether the chamber for house conferences or communication on Skype is necessary? Whether possibility of a sound recording, function of tracking the person will be required? As far as quality of the transferred image matters?
Let's consider key parameters of webcams.
Matrixes of webcams differ on manufacturing techniques. Today two of them - CMOS and CCD are popular. CCD matrixes as they give the better image are preferable, create less hindrances. Are of matrixes of CCD more expensive, than CMOS matrixes.
Resolution of the webcam – one of the most important criteria of its choice. Resolution is defined by quantity of points pixels from which the image is formed. Than more than such points and than they more small – the quality of the transferred image is higher.
Resolution of webcams can be ranging from 0,1 to 2 megapixels (Mpiks). For carrying out Internet conferences there is enough webcam with the resolution of 320х240 pixels. Chambers with the resolution of 640х480 pixels (0,3 Mpiks) will be suitable for record of small videos. Higher resolution, 1280х960 pixels, allows to take large-scale pictures. Models of chambers with such permission – the most expensive.
One more important parameter of webcams is a sensitivity of their matrixes. Sensitivity of a matrix defines illumination, minimum necessary for shooting. Sensitivity is measured in luxury (lux). Than value of this parameter in luxury is lower, especially shooting in the conditions of insufficient lighting will be qualitative.
Number of frames per second (fps) – an important indicator which determines the speed of record of the webcam. If speed insufficiently high, the reflected video turns out faltering, "slowed down". Because of technical restrictions which are imposed by servers, speed in the 15th shots/second is most often used. Also webcams with a speed of record of 30 personnel/second are popular.
Choosing the webcam, it is also not necessary to forget and about type of connection it to the computer. Modern webcams are usually connected by means of the USB interface. The USB 1.1 version which - today was outdate replaced it more high-speed version – USB 2.0.
Automatic targeting of focus, tracking position of the person, equipment by a microphone – all these additional options also matter at a webcam choice. If they are not useful for alleged operation of the camera, there is no need to overpay for their existence.
Appearance of a chamber and type of its fastening to the computer gets out only of preferences of the buyer. Round, square, on a support or attached to the monitor – the choice is.
