This project involves designing a network system for a 3-floor building with various devices and security features. The network connects 33 computers, 13 switches, motion detectors, CCTV cameras, servers, access points and other devices. The ground floor contains a parking area with security doors and smart lights. The first and second floors contain offices, training rooms, and a server room. All devices connect through switches to servers that provide DNS, DHCP, email, FTP and IOT functions. The total cost of the project is estimated at 2,426,755 Taka using a combination of star and hybrid network topologies with routers, switches and servers to maintain security.

2. Project Details
In this Project, I’m trying to develop basis network system and
give high security and use some modern devices.
Device:Computer, Printer, Switch, Router, Wire Cable, Some
digital devices like smart door lock,smart light etc . I’m using
some sensor like motion sensor, smoke detector,siren,fire
monitor etc. I also use a CCTV camera for security .
Device Works and Price (each device):Every device works for
every work. I’m describing each device part by part here.
Computer: I’m using a computer in informationzone , server
room ,training room, manager room, all the rooms for
communicatingeach room to another room . Every Computer
connected to a server. If anyone wants to give mail or transfer
files that person can transfer files or mail one computer to
another computer. This project, I’m using two types of
computer desktop computer and Laptop computer. Computer
Specificationis 21 inches monitor -10000tk, Power Supply700v-
1200tk, casing-2500tk, ram: DDR4 8 GB-3500tk, SSD 500 GB-
7000tk, Power cable-80tk. Other cable-100tk, Processor: core

Motherboard:GIGABYTE X299 UD4-40000tk. Full Computer Set
price= 114830tk.

3. Switch: A network switch (also called switching hub, bridging
hub, and is networking hardware that connects devices on a
computer network by using packet switching to receive and
forward data to the destinationdevice. In this project I’m using
Cisco SF300-24PP-K9 24-Port POE ManagedNetwork Switch.
Price 12800tk per piece.
Router: A router is a networking device that forwards data
packets between computer networks. Routers perform the traffic
directing functions on the Internet. Then, using information in
its routing table or routing policy, it directs the packet to the
next network on its journey. In this project work, I’m using Asus
ROG Rapture GT-AC5300 router- 29325tk.
Motion Detector: A motion detector is an electrical device that
utilizes a sensor to detect nearby motion. Such a device is often
integrated as a component of a system that automatically
performs a task or alerts a user of motion in an area. In this
project, I’m using Square Wall Recessed PIR Motion Detector-
500tk.
CCTV Camera: This camera only for monitoring. It givehigh
security. In this project, I’m using Dahua HAC-HFW1400D
4MP HDCVI IR Bullet Camera-3500tk.
Server: Network Server is a computer in Network that is
designated to provide one or more network service. For example
file server, database server etc. In this project, I’m using Dell
EMC PowerEdge R740 2U Rack Server- 620000tk and use

4. some ftp Dell EMC PowerEdge T140 Intel Xeon E-2134 16GB
Tower Server-135000tk.
AC: An air conditioner is a system or a machine that treats air in
a defined, usually enclosed area via a refrigeration cycle in
which warm air is removed and replaced with cooler air. In
construction, a complete system of heating, ventilation, and air
conditioning is referred to as HVAC. In this project, I’m using
Walton WSN-RIVERINE-24B Split AC - 1.5 Ton-56900tk.
Smart Light: In this project, I’m using Smart LED Light-
Sonoff B1 Dimmable E27 LED Lamp RGB Color Light Bulb
for Smart room. Every room has one smart light. Price- 1100tk.
Smart Door Lock: A smart lock is arguably the most important
part of a truly smart, connected home. Not only will it allow you
to come and go as you please, it will also monitor who is
entering and leaving your home while you're away. Some
models simply let you use your phone to open and close doors.
Price-17500tk.

Server details:In this project .I’m using
DNS,DHCP,FTP,EMAIL,IOT those 5 server
DNS sever:
A DNS server is a computer server that contains a database of public IP
addresses and their associated hostnames, and in most cases serves to
resolve, or translate, those names to IP addresses as requested. DNS

9. servers run special software and communicate with each other using
special protocols.
.

10. DHCP Server: A DHCP Server is a network server that
automaticallyprovidesand assigns IP addresses, default
gateways and other network parameters to client devices. It
relies on the standard protocol known as Dynamic Host
ConfigurationProtocol or DHCP to respond to broadcast
queries by clients.

11. Email Server: A mail server (or email server) is a computer
system that sends and receives email. Mail servers send and
receive email using standard email protocols. For example, the
SMTP protocol sends messages and handles outgoing mail
requests. The IMAP and POP3 protocols receive messages and
are used to process incoming mail.

12. FTP Server: The File Transfer Protocol is a standard network
protocol used for the transfer of computer files between a
client and server on a computer network. FTP is built on a
client-server model architecture using separate control and
data connectionsbetween the client and the server.

13. IOT Server: IoT Data Server is a "Data Integration
Controller" consisting of high reliable industrial computer and
non-programming data integration software. ... These functions
will help the data management in various scenes from the
production cell system to production line, factory, cloud system.

In this project work. I’m trying to give full effort to make this
project properly. I’m facing some problem. Then I take help
from Google and YouTube. At last, I can do this project
properly.
Topology:
In this project I am using star and hybrid topology. Star topology is
used to ease the probabilities of network failure by connecting all of
the systems to a central node. This central hub rebroadcasts all
transmissions received from any peripheral node to all peripheral
nodes on the network, sometimes including the originating node. The
advantages of a star network are: it is very reliable – if one cable or
device fails then all the others will continue to work. it is high-
performing as no data collisions can occur.
A hybrid topology is a type of network topology that uses two
or more differing network topologies. These topologies can
include a mix of bus topology, mesh topology, ring topology, star
topology. It is a type of network expensive. Design of a hybrid
network is very complex. There is change hardware in order to connect
topology with another topology. Usually hybrid architectures are
usually larger in scales so they requires a lot of cables in installation
process.

17. This Networks Topology Security System:
1.Routers use to maintain data security.
2.switch for protecting our data.
