  • What is Satellite TV?

    Satellite television (satellite TV) is a particular kind of broadcast delivery based on using space satellites to deliver signals. Companies make use of satellites that have been sent out of the Earth's atmosphere by beaming a signal up to the satellite and delivering it to individual customers via the use of receiving equipment.

    The basic setup for a satellite TV involves a satellite dish, also called a "parabolic reflector antenna," along with a "low-noise block down converter" and a receiver. Satellite TV helps deliver signals in areas where customers may not be served by cable television or "terrestrial" broadcasting.

    Satellite TV generally uses two different frequency sets to deliver signals. One is the Ku band, a dedicated channel for satellite TV communications. A type of satellite TV known as direct-broadcast satellite TV (DBSTV) often uses the Ku band. Other analog "big dish" systems use the lower C band, which is also used for certain other kinds of technologies. Although the Ku band is the dedicated channel for satellite TV, the C band can help signals withstand some interruptions, such as signal disruption from inclement weather.

  • What is CCTV?

    CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.

    CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere. Because the cameras communicate with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the designation "closed-circuit" to indicate that access to their content is limited by design only to those able to see it.

  • What is Home Theatre?

    Home theater is difficult to define -- it's really just a vague term for a particular approach to home entertainment. Generally speaking, a home theater system is a combination of electronic components designed to recreate the experience of watching a movie in a theater. When you watch a movie on a home theater system, you are more immersed in the experience than when you watch one on an ordinary television.

  • What is Data cabling?

    A data cable is any media that allows baseband transmissions (binary 1,0’s) from a transmitter to a receiver. Examples Are:

    Networking Media
    Ethernet Cables (Cat5, Cat5e, Cat6, Cat6a)
    Token Ring Cables (Cat4)
    Coaxial cable
    optical fiber cable; see fiber-optic communication
    Telecommunications Cable ( Cat2 or telephone cord)
    Data Cabling is a broad term which describes the running of data cables for a computer network environment, telecommunications equipment such as an office phone system, or other types of cable such as coaxial cable. Data Cabling can be subdivided into, and is often synonymous with, Network Cabling and Fiber Optic Cabling, since “Data” is a general term which may include networks and fiber optics.
