We often find illegal immigrants moving from one

Abstract
—We often find illegal immigrants moving from one 
country to another. By means of land these illegal immigrants 
move over the fence cut the border wires and moves to the 
other part of the land. What do you think our soldiers are not 
doing their job? It is not that actually. It is very difficult to 
watch consistently over the border. Soldiers have a limited 
vision to check around the whole land mass. So for them we 
have come up with a solution that we have built a device that 
will sense the presence of an intruder (illegal immigrant). This 
device will be installed over the fences. When an intruder 
passes over the fence this device will transmit the signal to the 
soldiers Smartphone app (BLYNK app). The soldier will be 
notified with the signal and after receiving the signal, the 
soldier can switch on the alarm and the emergency lights via 
the app. By this the soldiers in the camp will be alerted and can 
take their respective positions and arrest the intruder which 
was passing the border illegally. By this device we can alert the 
soldiers in the border to take more safety precautions to keep 
our country safe.

Description 
In Villages and in the areas near the border of a country 
people and the citizen of our country literally face many 
problems regarding security issues. People of different 
tribes of the other side of the border do come inside the 
border and attack our own civilians. Mostly they do a lot of 
harassment and they dominate over this people. They come 
and steal expensive items from the civilians. An estimate 
made in the year 2000 placed the total number of illegal 
Bangladeshi immigrants in India at 1.5 crore, with around 3 
lakhs entering every year. The rule of thumb for such illegal 
immigrants is that for each illegal person caught four get 
through. While many immigrants have settled in the border 
areas, some have moved on, even to faraway places such as 
Mumbai and Delhi. The trip to India from Bangladesh is 
one of the cheapest in the world, with a trip costing around 
Rs.2000 (around $30 US), which includes the fee for the 
“Tour Operator”. As Bangladeshi are cultural similar to 
the Bengali people in India, they are able to pass off as 
Indian citizens and settle down in any part of India to 
establish a far better future than they could in Bangladesh, 
for a very small price. This false identity can be bolstered 
with false documentation available for as little as Rs.200 ($3

there is fancy or boundary for the safety purpose but it’s not 
enough for security. The main purpose of the project is to 
enhance the border security electronically with automation 
and with that to reduce this kind of problems.

Solution 
And Using this concept we can easily identify if any 
strangers entering the border. And by this system we can 
make our border soldiers more alert. We are here with a 
solution that will help them to stay more alert regarding the 
intruders entering over the border. We will provide a device 
which will be there across the pillars of the border to detect 
the presence of any intruder entering the country. If any 
intruder is found entering the system will alert the soldier to 
take action. And automatically a buzzer will turn on to alert 
the soldier base camps.

EVIEW
Many analysts have been working on IOT and wireless 
sensor zones to provide the best security component. In this 
segment, we described different intrusion detection systems 
which are proposed in recent years. We have experienced 
different research papers and found what a were different 
security measures were used and what different strategy and 
thoughts overcome the problems.
