One of the highest resolution cameras in the digital video security industry is the 650 TVL color dome camera. Security Camera King has several different models of 650 TVL (TeleVision Lines) cameras and in this article we will take a close look at each camera. This should give you enough working knowledge to make your own comparisons and determine which one is right for you.

A quick word about resolution. As technology increases in complexity, it seems that the resolution of the cameras, the DVR's, and the display monitors is always increasing. A camera that offers 650 TVL means that its sensor, either a Charged Coupled Device or CCD or a Complementary Metal Oxide Semiconductor or CMOS, can reproduce the image seen in up to 650TeleVision Lines.

TVL is basically a carryover term that was used in the days of analog video. Today, there are very few new analog cameras available; digital is the wave of the future and is currently the standard for digital video security system cameras. However, camera manufacturers still reference their cameras in terms of TVL even though digital video can be more accurately described ...
... in terms of pixels.

A 650 TVL color dome camera means that the camera can produce a video image with up to 650 horizontal lines. We will purposely avoid the issue of resolution conversion between TVL, CIF, D1, etc, because of our limited space for this article. However, what is important to remember is that 650 TVL is a very high resolution, and only until recently it was the highest attainable. There are now cameras that are capable of 700 TVL in color or black and white. This should still give you a good idea how detailed a 650 TVL color dome camera is especially when compared to a standard resolution camera of 420TVL.

For the remainder of this article, we will focus on the 650 TVL color dome cameras that are available for purchase from Security Camera King.
