Spy Camera Resolutions

Introduction to Resolution

When you see different resolutions for covert spy cameras, the higher the resolution, the better the image quality you get.

For example, if you take VGA resolution of 640 pixels by 480 pixels, this means there are 640 pixels wide, and 480 pixels high in any single frame of a picture or movie captured by a spy camera. If you think of pixels as being a single dot of picture information, then in a VGA image, there are a total of 307,200 pixels.

Images captured in QVGA resolution have 1280 pixels in width, and 1024 pixels in height, which means there are 1,310,720 pixels. That means there’s over 4 times as much information in a QVGA image as there is in a VGA image!

Image Sizes

So number-crunching aside, exactly how do the different resolutions relate to each other? Well, here’s a diagram that puts the different sizes into perspective for you.
