Wireless Cameras For Morons: How To Pick Between QVGA And VGA Resolution
Cameras often have VGA and QVGA screens. Unfortunately, few of us are mindful of the way the resolution of one actually differs greatly from the other. This is the reason why this document has been written – it is structured to give you more information with respect to VGA and QVGA screens when using them with wireless cameras.
How VGA screens vary from QVGA screens is pretty simple. 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, comes with only a quarter of the area of a VGA screen. That being said, a QVGA screen has got only 1/2 the width and height of a VGA screen. That means 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 fact is that these are the screens employed by most security wireless cameras that exist today. Fortunately whatever security camera you purchase, you will generally be able to get both these resolutions. If you like your wireless cameras to capture pictures and videos with a QVGA resolution, you’ll improve frame refresh rates, meaning more frames per second ( fps ), yet rather unclear images 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 will get less fps.
Now, if you are thinking how much security wireless cameras can cost, 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’re truly short of a security camera, there are tons of web stores that can help you. Of course, remember that if the resolution of your wireless cameras is too low, then photographs might be misleading which will generally make them less handy as security.
All you’ve got to do is simply put some keywords you suspect could be important into the major search engines and thousands of stores will be brought to you in a matter of a few seconds.
