An HD camera, of High Def Camera as they are also called, sounds fancy but what is it, really?
“HD is a type of megapixel camera. All HD cameras are megapixel but not all megapixel cameras are HD.”
These cameras are slowly replacing the older SD cameras many people still have.
We found this article that explains it really well and instead of pulling out quotes, we recommend you read it in its entirety if you are interested in knowing the difference between an HD camera and a megapixel camera.
This is a loaded question!
“We want you to be safe” is the standard answer but there is so much more to having security cameras than safety in your place of business and your home!
In ‘5 reasons why security cameras rock‘ we touched on the following 5 reasons.

Let’s look a this quote:
In the correct application HD and megapixel cameras can be of great advantage as well as cost effective. Because of the pixel density in this technology it is possible to look at large areas while maintaining the detail that would require multiple SD cameras. This pixel density can allow the ability to zoom into the scene live or for forensic review, giving the system greater flexibility and performance. How much you can zoom into the scene is determined by the area being viewed and the pixel density.
Now let’s look at the application
To illustrate this, consider the application of wanting to view license plates within a scene. This typically requires 50 pixels per horizontal foot for a clear, readable image. With a SD camera the largest viewable area that maintains 50 pixels per foot is 10 ft. wide. Compare that with a 1.3MP or 720p camera at 25 ft., a 2MP or 1080p at 30 ft., 41 ft. with a 3MP and 51 ft. with a 5MP. In this example it is possible to replace as many as five SD cameras with one megapixel camera. Not only is this a savings on cameras but also cable, labor and any accessories needed for the camera installation. Instead of five cable pulls there is one — and only one time up the ladder, one camera to focus, one camera to maintain. The savings can add up quickly.
There you have it!
Besides being able to get a clearer image off of the footage, replacing (or installing) SD security cameras with HD cameras saves you money because you need fewer cameras to do the same job and that also means you save money on installation, maintenance and up keep!
