Cameras often have VGA and QVGA screens. Sadly, few of us are aware of the way the resolution of one basically differs greatly from the other. This is the reason why this article has been written - it is intended to offer you additional information with regard to VGA and QVGA screens when using them with wireless cameras.
How VGA screens vary from QVGA screens is very easy. It's about their resolution. A VGA screen has a maximum resolution of 640x480 pixels. That means 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 being said, a QVGA screen has only half the width and height of a VGA screen. That means that a QVGA screen has a maximum resolution of 320x240 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 reality is that these are the screens used by most security wireless cameras that exist today. Luckily whatever security camera you purchase, you will generally be able to get both these resolutions. If you prefer your wireless cameras to capture pictures and videos with a QVGA resolution, you will get better refresh rates, meaning more frames per second ( fps ), yet rather misleading pictures and videos. On the other hand, if you set your security camera to capture pictures and videos with VGA resolution, you will get clearer images and videos, but you may get less fps.
Now, if you are thinking how much security wireless cameras can cost you, this will rely upon the maximum resolution the camera can offer. The higher the resolution of the camera, the bigger the price tag will be ; but if you're really wanting a security camera, there are heaps of web stores that will help you. Naturally, remember that if the resolution of your wireless cameras is too low, then photos might be confusing which will generally make them less useful as security.
All you have to do is just put some keywords you believe may be important into the major search engines and thousands of stores will be brought to you in a matter of a couple of seconds.
