Ten
Greatest Myths about IP-Surveillance |
|
|
|
There are a number of myths, large and small, surrounding IP-Surveillance
technology. We’ve taken the 10 most often-heard myths and organized
them into two categories: general and technical. We’ll take the
general un-truths first and then launch into some of the technical
misperceptions |

Myth
#4: Networked video image quality is not as good as analog. |
|
|
Reality: Good quality network cameras have the same high quality
image sensors (CCDs) and optics as analog security cameras.
Furthermore, by employing video servers an analog speciality camera
or existing already installed analog cameras can be incorporated
into an IP-Surveillance system. In comparing network and analog
cameras, we must emphasize “good” quality network cameras, built for
professional use. These high quality professional network cameras
should not be confused with lower-end network or PC webcam cameras
used for “web attraction.” Indeed these cameras cannot deliver the
same capabilities as a full-function network camera.
Soon, network cameras and IP-Surveillance technology will deliver
superior image quality by means of mega-pixel resolution. Analog
cameras are limited by the 0.4 Mpixel resolution of NTSC/PAL
standards.
