CCTV Camera

CCTC Camera manufacturers provide product specification sheets that help you select the right camera for your IP security and surveillance system. But, which specifications are important? They include such things as resolution, minimum light sensitivity, lens, WDR, signal to noise, etc. This article reviews the important camera specs, and how to avoid being fooled by specsmanship (from the marketing department).

The importance of each of the camera specifications depends on your objective and application for your IP camera system. For example, if you want to use the camera outdoors where it can get dark, then the low light specification is important.
This usually refers to a camera with over 8 Megapixels of resolution. It has approximately 4,000 horizontal pixels. There is some difference between the definitions of the television industry and the security market. The number of vertical and horizontal pixels and the aspect ratio are defined differently. For example, Axis introduced a camera with 3840 x 2160 which runs at up to 30 fps (which they called Ultra HD). The Sony 4K IP camera has a chip with 4096 H × 2160 V pixels which run at up to 60 fps and conforms to the Digital Cinema Initiative. has a resolution of 4000 x 3000 pixels. The marketing people call all these cameras “4K”.
