The communication system is a system which describes the information exchange
between two points. The process of transmission and reception of information is called
communication. The major elements of communication are the Transmitter of
information, Channel or medium of communication and the Receiver of information.
Telephone system is a communication system that transmits sound between distant
points. phone system. transmission line, cable, line - a conductor for transmitting
electrical or optical signals or electric power.
TELEPHONE, CABLE TV & VIDEO SYSTEMS
Cable television is a system of delivering television programming to consumers via
radio frequency (RF) signals transmitted through coaxial cables, or in more recent
systems, light pulses through fibre-optic cables. This contrasts with broadcast television
(also known as terrestrial television), in which the television signal is transmitted over-
the-air by radio waves and received by a television antenna attached to the television; or
satellite television, in which the television signal is transmitted over-the-air by radio
waves from a communications satellite orbiting the Earth and received by a satellite dish
antenna on the roof.
Video System means a video, physical or other mechanical, electronic, digital, or
wireless system or device that enables continuous or periodic video recording,
observing, or monitoring of individuals in public spaces or within Township operated
An intercom system is a two-way communication electronic device that contains
circuitry for the purpose of transmitting and receiving audio and/or video transmissions.
With the advent of cellular communication, digital telephone systems, and other
communication devices, the use of intercoms has declined. However, there are still lots
of applications where these devices still work better than anything else. There are a very
wide variety of systems available as defined below:
Wireless Intercoms: In applications where wires cannot be run, a wireless system is
used. There is a broad spectrum of two-way wireless communication devices that
include such devices as handheld radios, outdoor wireless callboxes, as well as
traditional desktop devices. The range these units will transmit varies widely based on
the wireless technology used.
Wired Intercom Systems: When you can run wires between locations, a wired system
can give you a little more privacy and eliminate possible interference from neighboring
systems. There are different wire types such as 2-wire shielded or Cat-5/6 that can be
INTERCOM & PA (PUBLIC ADDRESS)
used with these systems. If you are considering a video system, a wired unit may be the
Video Intercom: These typically have a unit that has a camera, speaker, and a push
button that goes at an entrance door, and an internal monitor unit that can
communicate with the entrance unit. Some systems can have multiple video monitors
internally. Given the difficulty of sending video over the airwaves at very much distance
without interference, most available units are wired.
Apartment Intercoms: This type of system has a door unit at an entrance door and
then each apartment or flat has either one or multiple units that can speak to the door
and possibly see the visitor, or the door unit rings a landline or cellular telephone
number. A visitor simply presses the correct button for the apartment they want to
speak to, and the tenant can speak back and then press a button to unlock the door.
A public address system (or PA system) is an electronic system comprising
microphones, amplifiers, loudspeakers, and related equipment. It increases the apparent
volume (loudness) of a human voice, musical instrument, or other acoustic sound source
or recorded sound or music. PA systems are used in any public venue that requires that
an announcer, performer, etc. be sufficiently audible at a distance or over a large area.
Typical applications include sports stadiums, public transportation vehicles and facilities,
and live or recorded music venues and events. A PA system may include multiple
microphones or other sound sources, a mixing console to combine and modify multiple
sources, and multiple amplifiers and loudspeakers for louder volume or wider
High technology (high tech), also known as advanced technology (advanced tech) or
exotechnology, is technology that is at the cutting edge: the highest form of technology
available. It can be defined as either the most complex or the newest technology on the
market. The opposite of high tech is low technology, referring to simple, often
traditional or mechanical technology; for example, a slide rule is a low-tech calculating
device. When high tech becomes old, it becomes low tech, for example vacuum tube
HIGH TECHNOLOGY SYSTEMS
BUILDING AUTOMATION SYSTEM(BAS)
A building automation system (BAS) allows an operator to access, control, and monitor
all connected building systems from a single interface. With BAS technology, you can
gain centralized control over your building’s systems via networked electronic devices.
In the past, fine-tuning HVAC, lighting, power, and access control systems required
extensive manual effort. With new building automation solutions, you not only integrate
these historically siloed systems, but you also gain visibility and control over them from
a single view. That streamlines decision-making and saves you time.
Another key benefit of building automation is that it resolves the long-standing
competition between more comfort versus more efficiency. With reams of new data, you
can make informed decisions about how to best reduce or eliminate energy waste. For
example, if rooms are unoccupied, you can turn the lights off or reduce HVAC output
until the occupants return. And when they do return, occupants gain greater control
over their living spaces via app-based room controls. The result is lower costs and
Robotics is an interdisciplinary branch of computer science and engineering. Robotics
involves design, construction, operation, and use of robots. The goal of robotics is to
design machines that can help and assist humans. Robotics integrates fields of
mechanical engineering, electrical engineering, information engineering, mechatronics,
electronics, bioengineering, computer engineering, control engineering, software
engineering, mathematics, etc.
Robotics develops machines that can substitute for humans and replicate human
actions. Robots can be used in many situations for many purposes, but today many are
used in dangerous environments (including inspection of radioactive materials, bomb
detection and deactivation), manufacturing processes, or where humans cannot survive
(e.g. in space, underwater, in high heat, and clean up and containment of hazardous
materials and radiation).
Intelligent buildings are facilities that leverage complex automated systems to maximize
operational efficiency and the well-being of occupants. Historically, the term often
referred to structures built for sustainability instead of smart technology.
CHARACTERISTICS OF INTELLIGENT BUILDING
Reliable internet connectivity
All intelligent buildings need internet access to leverage the IoT capabilities of devices in
their networks. Simply adding WiFi routers isn’t enough designers need to maximize
coverage, avoid building materials that block signals and have contingencies in place for
emergencies. For these reasons, Ethernet cables are the most reliable infrastructure for
bringing various systems together.
When something breaks down in an intelligent building, facility managers need to get it
running as quickly as possible. these systems can use preventative maintenance tools to
monitor performance and recommend inspections in advance. In addition, building
designs should include easy maintenance access to hardware and software assets across
the entire structure.
The most common energy waste occurs from everyday inefficiencies, such as always-on
lights or overactive air conditioning. Intelligent buildings can automate this usage to
reduce costs and promote sustainability. For example, the facility might adjust climate
controls based on the number of occupants in each space. Workspace lighting may
activate when a desk is in use and switch off once everyone leaves. These efficiencies
add up over time, reducing operating expenses.
Automated and personalized services
Both intelligent and smart buildings have similar features that combine IoT devices,
online connectivity, and energy efficiency. One key difference is automation while smart
buildings offer interfaces to control facility operations, intelligent buildings manage
them automatically. Advanced networks use sensors to detect tenant locations and
predict where they will be before optimizing the building environment accordingly.
