If you are shopping around for a video security system you may find it confusing when trying to figure out the quality of the different megapixel surveillance cameras. Basically, the more megapixels a camera is able to capture the higher the resolution. There are, however, several other factors that need to be taken into account if you want to get the right security equipment for your particular needs. If you are working with staff members of a professional security company they will be able to advice you on the options and features best suited for your situation.
Basically a pixel is the smallest screen element that can be manipulated or captured by devices rated as megapixel surveillance cameras. If you zoom in on your computer screen each individual pixel is represented by either a dot or a square. Each pixel is one small piece of the entire picture. When it comes to digital information, the more pixels your camera captures the more digital information you will have to transmit over your data lines or store in a file. More pixels alone though does not guarantee a better image. You will want to find a camera that has a high quality lens that is sensitive enough to get the quality of image you want.
Megapixel surveillance cameras are used extensively when higher quality results are needed. The systems can easily capture enough detail to read license plates, monitor the activity at a casino and keep an eye on customer transactions at cash registers. The systems are sophisticated enough to be used in government buildings where security is vital. The more advanced systems can be used with other detection systems such as face recognition software. Despite their complexity, they are also simple enough to understand that almost any homeowner with even the most basic technical knowledge can install and use them in a matter of hours. If you are looking to purchase a system make sure and buy the right kind of cameras to help you protect your property.
