IP cameras excel in capturing high definition, megapixel images but have trouble with low lighting conditions.
Dropped frames and video artifacts are commonly seen in IP CMOS cameras. IP cameras are limited in encoding resources. As a result choices have to be made with respect to codec, frame rates and quality where the selection of one decreases quality of another. Since the video is being compressed before monitoring, you can never have
the highest quality or real time images. Encoding at the camera introduces latency, which becomes an issue when
an operator needs to track something with a PTZ controller and overcorrects.

Analog CCD cameras perform well across a variety of lighting conditions and manage motion well. Analog cameras do not have capabilities above the NTSC/PAL standards. As analog compresses the video in the DVR there are more hardware and software resources available to provide increased video quality and frame rate. Analog cameras transmit the video image to the DVR uncompressed where it can be viewed live with no latency pre-compression. Which is Better? An IP Camera or an Analog Camera? Video Quality
