If you need security and surveillance coverage in poorly lit or no light areas, you should try using an infrared camera system. In the following article we’ll talk about how these cameras work and what to look (out) for when purchasing a system.
Under normal daylight conditions a digital video security camera utilizes the light waves that are reflected from the objects in its field of vision. It does this by using a lens to focus the entire image onto a sensor chip that is usually 1/4 or 1/3 of an inch square. The sensor chips work by converting the light energy into a small electrical impulse which can be measured and therefore ultimately used to create a digital video image.

The dome security camera is one of the most popular types of digital video security camera in use today. Thanks to modern technological advances a lot of electronic power can be packaged inside a small 3.5 inch diameter dome camera. Not only are they small and powerful, but the average dome security camera is light weight as well (in most cases weighing just under one pound), which makes it easy to mount just about anywhere.
Today, there are three standard types of digital video camera based on shape; the box type, bullet type, and dome security camera. How, what, and where the camera is used usually dictates the type, although user preference is also a factor.
