The Megapixel Myth – More Is Always
Better [Part I]
The demand and use of IP cameras, for video surveillance
requirements, is growing rapidly; and the time is right to discuss how
important the megapixel rating of a camera is, for good quality video
capture. This article is split into two parts for easier readability.
The popular view, in the digital photography world, is
that the more the megapixels (supported by the camera) the better is the
quality of the captured image or video. This simplistic view ignores
the subtleties behind image capture, and this note sheds light on two
important components of a camera’s content capture mechanism: the sensor
and the lens.

The Megapixel Myth – More Is Always
Better [Part 2]
The first part of this article focused on the
specifications of the camera sensor that impact image quality. In Part
II, we will examine the other component of a camera’s content capture
mechanism critical to image quality.

NAT Traversal for IP Video
Surveillance Application
Network Address Translation (NAT) is a technology that
has, in a small way, revolutionized Internet communications. NAT allows
multiple computers on a LAN to share a single public IP address for
accessing the Internet. NAT also hide private hosts; causing peers not
reachable globally. In NATed environment, general firewall/NAT gateway
does not allow incoming connection to private addressed hosts. This
makes it hard to locate and communicate with the private hosts behind a
NAT gateway.

Choosing Analog Or IP Camera Systems
For Video Surveillance (CCTV)
This article provides as simple as possible an explanation
of the factors which indicate analog, IP, and hybrid IP/analog video
systems respectively. It seeks to provide a reference for editors,
end-users, and integrators who may need to evaluate a specific case or
understand the general principles. More... |
