Cameras regularly have VGA and QVGA screens. Unfortunately, few of us are conscious of the way the resolution of one actually differs greatly from the other. This is the reason why this article has been written – it is designed to give you additional info with regard to VGA and QVGA screens when using them with wireless cameras.
How VGA screens vary from QVGA screens is fairly easy. It’s about their resolution. A VGA screen has a maximum resolution of 640×480 pixels. That implies the maximum width of a VGA screen is 640 pixels while the maximum height is 480 pixels.
A QVGA screen, on the other hand, includes only a quarter of the area of a VGA screen. That said, a QVGA screen possesses only half the width and height of a VGA screen. That means a QVGA screen has a maximum resolution of 320×240 pixels. This is the reason why it is named QVGA which stands for Quarter VGA.
What do VGA and QVGA screens have to do with wireless cameras? The fact is that these are the screens employed by most security wireless cameras which exist today. Fortunately whatever security wireless camera you purchase, you may typically be in a position to get both of these resolutions. If you like your wireless cameras to capture photographs and videos with a QVGA resolution, you will improve frame refresh rates, that means more frames per second ( fps ), yet rather confusing images and videos. On the other hand, if you set your security camera to capture photographs and videos with VGA resolution, you will get clearer images and videos, but you’ll get less fps.
Now, if you’re thinking how much security wireless cameras can cost you, this will depend on the maximum resolution the camera can offer. The higher the resolution of the camera, the higher the price tag will be ; but if you are truly short of a security camera, there are heaps of web stores that will help you. Of course, remember that if the resolution of your wireless cameras is too low, then photographs might be unclear which will make them less useful as security.
All you have got to do is just put some keywords you think may be applicable into the major search engines and thousands of stores will be brought to you in a matter of a couple of seconds.
