Defining the World of Security Cameras
Finding the right security camera is difficult enough without
having to wade through the terms and figure what the
abbreviations and words actually mean. If you're trying to do
research on a security camera and frustrated with the multitude
of terms that are unknown to the average user, here's a list of
the terms you'll want to know. There are many more out there,
but this is enough to get you started:
DVR: Digital Video Recorder, or 'personal video recorder.'
Usually used when referring to a Security Camera System, you use
a DVR to record broadcasts on a hard disk drive which can then
be played back at a later time. The most well-known type of DVR
is TiVO. They often come with standard features like motion
detection, time and date stamping, and remote internet
monitoring capabilities.
Motion Detection: Many cameras and DVRs are built with motion
sensors to track movement securely.
Time and Date Stamping: Term used when a DVR records the date
and time of an occurrence or recording.
Remote Internet Monitoring: Refers to using a camera like a
Network IP Camera to record information and the ability to see
that information live in real time from a distant location.
PC: Still refers to a personal computer.
PTZ: 'Pan, Tilt, Zoom' refers to the motion of a controllable or
PTZ camera. Movement can go from left to right and up down, as
well as zoom in and out on an object.
Infrared: A technology that uses heat sensors to detect objects
in its surroundings. It was developed especially to 'see' in the
dark.
Network IP Camera: refers to a type of camera that connects to
the internet or a computer network via an IP address and can be
viewed remotely from different locations.
DVR Card: Digital Recorder Card. Provides digital video
recording capability so that you can store video files from your
security/surveillance system on your PC.
Camera Housing: Refers to the outer shell of a security camera.
It serves to weatherproof, protect, and 'house' the camera from
potential harm.
Quad Processor: four processors in one
Multiplexer: the multiplexer takes several separate digital data
streams and combines them together into one data stream of a
higher data rate. A multiplexer makes it easier to combine the
data from several security cameras into one stream of
information. This is system is a quicker and more effective way
of processing information.
Multiple Output Power adaptor: a power adaptor that enables
multiple outputs and is highly useful for a system that requires
a good amount of power.
Security Camera Systems: General, broad term for the package
that security companies often sell. They are usually a better
deal than buying the items separately and come in a variety of
choices. They usually include a security camera, Processor,
Software, Cables, Power Adaptor, Monitor, VCR/DVR, and some come
with a warrantee. This is one of the more basic kits; more
deluxe options often entail other accessories.
Dome Security Cameras: Dome security cameras are ideal for use
in building entrances, stores, and shopping malls; in short,
anywhere you want a 'fashionable' camera that is designed to
blend into its surrounding environment. Prettier and more
appealing than its cousins, a Dome Camera offers high security
and an increased surveillance capacity because of its
non-invasive qualities.
PTZ (Pan, Tilt, Zoom) and Controllable Cameras: PTZ and
Controllable Cameras are designed to be controlled by remote or
through a DVR. They have the ability to move up and down as well
as right and left. You can pan, tilt, and zoom in or out. You
have all the control you want over these cameras, and they
provide excellent surveillance and security.

type of small, sleek camera that that is ideal for both indoor
and outdoor installation. Sealed in cylinders and totally
protected, they are impermeable to water and are totally
weatherproof. Mountable on the ceiling or on the wall, they
provide sharp, detailed video images while maintaining low
profile visibility and an unobtrusive presence.
Mini, Board and Covert Cameras: Just as they sound, mini
cameras are small, tiny cameras that come in wireless options
and can be used for increased, quiet security. Board cameras are
tiny mini cameras set in small, flat housing, and are also
highly useful in situations calling for more security and
extremely low visibility. A Covert Camera is just what it sounds
like. Like the mini and board cameras, covert cameras are
intended for use for those that need increased security and a
totally unobtrusive camera.
Pro Security Cameras: Professional Security Cameras are ideal
for any and every purpose you might have. They can be mounted on
ceiling brackets, on your wall, and indoors and outdoors. The
