Introduction
Wireless security cameras are closedcircuit television (CCTV) cameras that
transmit a video and audio signal to a
wireless receiver through a radio band.
Many wireless security cameras require at
least one cable or wire for power; "wireless"
refers to the transmission of video/audio.

Camera
Any IP camera can be made wireless with the
addition of an external antenna or transceiver.
IP cameras come in an incredibly varied
selection with options for fixed, PTZ, indoor,
outdoor, day/night, and more.

Power Distribution Board
A distribution board (also known as panel board,
breaker panel, or electric panel) is a component of
an electricity supply system that divides an electrical
power feed into subsidiary circuits, while providing a
protective fuse or circuit breaker for each circuit in a
common enclosure.

Network Video Recorder
NVRs are responsible for video monitoring and
storage. NVRs capture video streams from remote IP
cameras and store the footage on a hard disk.

Antenna
An antenna is a specialized transducer that converts
radio-frequency (RF) fields into alternating current
(AC) or vice-versa. There are two basic types: the
receiving antenna, which intercepts RF energy and
delivers AC to electronic equipment, and the
transmitting antenna, which is fed with AC from
electronic equipment and generates an RF field.

Switches
A switch is a device in a computer network that
electrically and logically connects together other
devices. Multiple data cables are plugged into a
switch to enable communication between different
networked devices. Switches manage the flow of
data across a network by transmitting a
received network packet only to the one or more
devices for which the packet is intended.

Surge Suppressor
The surge protector has only one job: detect excess
voltage that may travel through an Ethernet cable
and divert the extra electricity into the grounding
wire before . This is why all surge protectors will
have a grounding pin and all surge protectors must
be plugged into a properly grounded outlet for
them to work as intended.

Introduction of ANTENNA
An antenna or aerial, is an electrical device
which converts electric power into radio waves,
and vice versa. It is usually used with a radio
transmitter or radio receiver.
Antennas can be designed to transmit and receive
radio waves in all horizontal directions equally
(omnidirectional antennas), or preferentially in a
particular direction (directional or high
gain antennas)
Types of Antenna
Directional antenna
Directional and semi-directional antennas focus radiated
power into narrow beams, adding a significant amount
of gain in the process.
Antenna
properties
are
also
reciprocal.
The
characteristics of a transmitting antenna, such as
impedance and gain, are also applicable to a receiving
antenna.
This is why the same antenna can be used for both
sending and receiving. The gain of a highly directional
parabolic antenna serves to amplify a weak signal; this
is one reason why this type of antenna is frequently
used for long distance links.
Types of Antenna
Sector antenna
Sector antennas are another type of semi-directional
antenna. Sector antennas provide a pie-shaped
(sector) radiation pattern and are usually installed in
what is known as a sectorized array. Beamwidth for
a sector antenna can be between 60 to 180
degrees, with 120 degrees being typical.
Types of Antenna
Mode of Operation
Access Point (AP)
An access point is a station that transmits and
receives data (sometimes referred to as a
transceiver). An access point connects users to
other users within the network and also can serve
as the point of interconnection between the WLAN
and a fixed wire network.
Mode of Operation
Subscriber Module (SM)
The Subscriber Module (SM) is the subscriber
termination unit. It consists of a single transceiver.
Mode of Propagation
Point-to-Multipoint (PMP) Radios
Point-to-multipoint communication (P2MP,
PTMP or PMP) is communication which is
accomplished via a distinct type of one-to-many
connection, providing multiple paths from a single
location to multiple locations.
Mode of Propagation
Point – to – Point (PTP)
Point-to-Point Radios are configured in pairs and are
used to communicate between two nodes or
endpoints.
The strengths of PTP Radios include simplicity of
installation, secure wireless connection, long range,
and above all cost effectiveness in transmission of
data.
