Cameras - IP
The subject of resolution (pixels per given area of a picture) is irrelevant of technology choice. That means that a given resolution 4CIF (704 x 480), 720p (1280 x 720), 1080p (1920 x 1080 or 2MP) and beyond is the same regardless of camera type. Therefore, you may want to briefly review everything we said with respect to resolution in our HD-Camera section because it is also true about Mega-Pixel IP cameras.
Now... to the subject...
IP (Internet Protocol) cameras are different from analog cameras in that the video data that comes from them is "digitized" (translated from an analog voltage signal to a digital file) at the camera level and IP cameras have a unique IP address (network static and/or MAC Address) that allows their data to be accessed directly without having to connect to other network hardware.

Typical IP Camera (an inside look)
Our "simplified" graphic (right) diagrams the “inner workings” of a typical IP camera and includes only the "key" components.
A brief review of the diagram reveals IP cameras are really analog cameras with the addition of a video processor and some ancillary interface parts. In fact, one can add a video encoder to an analog camera and "create" the benefits of an IP camera.
TYPICAL IP CAMERA (it's a VALUE choice)
Once upon a time, much of the "IP information" (literature publication or technical articles) that was available in trade journals or on the Internet was written by or for people or companies that had a vested interest in promoting their IP products. Fortunately, that's no longer the case.
Similar to virtually every other "new technology," marketplace competition and time have lowered the cost of IP cameras significantly. Additionally, the IT issues that once provided understandable concern (and therefore resistance from the IT community) have been solved with simple and inexpensive work-arounds.

At GuardDog Surveillance Systems, even though we once embraced a position wherein we provided a combination of analog, HD and IP cameras (hybrid systems), numerous technological and economic changes have forced us to alter our thinking.
Since we have no vested interest in the sale (of analog, HD or IP equipment) and our primary purpose has always been that of providing video security solutions that best serve our customer's application requirements, IP technology has risen to the top and today provides the greatest overall system value.
In the ensuing pages, we detail the benefits, are candid about the downsides and ultimately provide a middle of the road, application experience oriented perspective on what we feel is best overall value solution - and we explain why. This section concludes with a dramatic presentation of Mega-Pixel IP cameras.
