CCD stands for Charge Coupled Device(s). They are responsible for turning RGB light into electronic RGB signals. They are usually located directly behind the lens of the camera.

Quality can refer to both how detailed the image is and how fast the frame rate is. Frame rate is simply a measure of how many individual pictures make up the video. "Full motion", what you see on television and on VHS tapes, is 30 frames per second, or fps. Most often, security systems record at slower rates, which result in more jerky-looking images but saves tape or hard drive space, allowing longer periods of time to be recorded How does an Infrared Illuminator work? In situations where events need to be monitored at night, black and white cameras are used with infrared illuminators. Infrared light is used because black and white CCD cameras have very good sensitivity in and near the infrared region. These are wavelengths longer than 7000nm (nanometers). The human eye can see up to 700nm wavelength, and anything above 700nm is invisible to the human eye. Most infrared illuminators come in 730nm, 830nm, and 950nm wavelengths. These infrared illuminators are invisible to the human eye, and that's why they're perfect for night monitoring. You will be able to see in total darkness with these infrared illuminators, without anyone knowing What is a camera's format? Camera formats are measured in inches: most surveillance cameras fall between 1/4" and 1". This refers to the usable image size created inside the camera. For most security systems, a small size is fine - 1/4" or 1/3" surveillance cameras dominate CCTV sales. Larger formats do not necessarily result in better images, but can be advantageous in dimly lit situations since they are able to gather more light Package Included: 1 x Mini 1/4" SHARP Security CCTV Wired Color CCD Camera
