Resolution for security camera is an important thing. You have to need this specification when you buy a surveillance camera. Usually, for CCTV cameras, the resolution have range from 330 TVL (television lines) to 600 TVL. There is 2 option for CCTV cameras, black and white, and color. The maximum out as 560 lines for color resolution. But for black and white in 600 TVL.

Now You can find IP security camera in higher resolution, greater than 5 megapixels. In several country, regular TV transmission displays picture in resolution 480 lines. Actually, the detail of pictures are depend on the resolution, the higher resolution you choose, the more detail surveillance video you can see.

High definition television (HDTV) has resolution around 720 or 1080 lines, depend on the type HDTV you have and the channel you choose. If you need detail of surveillance camera, you have to choose higher resolution. The suggestion is IP based megapixel cameras, not choose a closed circuit, but connect over an IP network.

The fact, IP megapixel security cameras are more expensive than CCTV cameras. Because for high end product with ultra-high resolution, IP megapixel cameras can capture video with more detail twice than the detail of high definition television resolution.
Several people are unrealistic when shopping for a security camera. This behavior due to lack of experience. They have choosen wrong the specification of surveillance camera rather than what they needed. The camera cannot pick the picture up at 80 feet away with 3.6mm lens, while the lens can easily pick the object up in detail at 20 feet away.

Due to the very expensive price difference between IP megapixel cameras and CCTV cameras, it makes sense if people prefer to add additional CCTV cameras instead of upgrading their megapixel cameras.

It is realistic that the higher price of the security cameras, the higher resolution and the higher detail of the video you can see.
