Today’s security market is going crazy! People are scrambling to protect themselves, their families, possessions, businesses, etc. The economy has created a whole new wave of crime and out of control is only the start of the description of what’s going wrong. This craze has in turn created a new type, style, and breed of consumer. Oblivious, and its not their fault. Most retailers confuse the average guy or girl so badly that “up” isn’t even a direction anymore. Well, I’m going to sort all of that out for you. By the time you’ve gotten through this brief read, you’ll be armed to the teeth with information that your average reseller isn’t even going to have. Let’s get into it!
Let’s delve into the world of resolutions and the pixels that they consist of. First what do you know (or understand) what a picture is? I’m sure you’ve been inundated with the term of “1080P”. Or “10 Mega Pixel on the go everyday activity camera” but do you really understand why this is so? Now that I have you questioning yourself, do you wonder if these terms truly mean and represent a higher standard of quality you’re hyped to expect? Let’s begin with trying to grasp how our quality comes into play, it’s known as PAR (Pixel aspect ratio). It is a mathematical ratio that describes how the width of a pixel in a digital image compares to the height of that pixel (Very similar to square feet in units of measurements for buildings). There are a number of articles and tutorials online about this subject. To make the matter even worse there is a complicity of the PAR/DAR/SAR terminology but I will try to present the problem as simply as possible, and in regards to display monitors and DVR exporting instead of motion film cameras. After all, were all here to obtain knowledge in our security devices and how to choose wisely.
