Wireless Cameras 101: Picking Between QVGA And VGA Resolution
Cameras frequently have VGA and QVGA screens. Unfortunately, few of us are aware of how the resolution of one essentially differs greatly from the other. This is why this draft 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 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 being said, a QVGA screen possesses only half of the width and height of a VGA screen. That suggests a QVGA screen has a maximum resolution of 320×240 pixels. This is why it is named QVGA which stands for Quarter VGA.
What do VGA and QVGA screens have to do with wireless cameras? The truth is that these are the screens employed by most security wireless cameras that exist today. Fortunately whatever security camera you buy, you may sometimes be able to get both of these resolutions. If you like your wireless cameras to capture images and videos with a QVGA resolution, you will improve frame refresh rates, that means more frames per second ( fps ), yet rather confusing pictures and videos. On the other hand, if you set your security camera to capture images and videos with VGA resolution, you’ll get more clear images and videos, but you may get less fps.
Now, if you’re considering how much security wireless cameras can cost you, this will rely upon the maximum resolution the camera can offer. The bigger the resolution of the camera, the bigger the ticket will be ; but if you are actually 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 may be confusing which will make them less useful as security.
All you have to do is simply put some keywords you believe might be important into the major search engines and thousands of stores will be brought to you in a matter of a few seconds.
