How IoT helps in Law Enforcement

Crime was present earlier and is prevalent now as well. So, what has changed? Cyber crimes have become extremely frequent now with the the internet being sabotaged to obtain sensitive data. So, what we created in the first place to make our lives easier have come back to bite us.

But, what if I told you that the same technology could be used to keep track of these crimes, be it cyber or your day-to-day thefts, wouldn’t you be surprised? With IoT now, even that problem will be solved now.

So what is IoT?

According to Webopedia, IoT is short for Internet of Things. The Internet of Things (IoT) refers to the ever-growing network of physical objects that feature an IP address for internet connectivity, and the communication that occurs between these objects and other Internet-enabled devices and systems.

So, when every Internet-enabled device can talk about its surrounding through sensing (sensors) and then utilizing that information to add value to the use case, identifying crimes become easier.

In the IoT sense, “devices” can refer to a wide variety of devices such as heart monitoring implants, biochip transponders on farm animals, electric clams in coastal waters, automobiles with built-in sensors, DNA analysis devices for environmental/food/pathogen monitoring, or field operation devices that assist firefighters in search and rescue operations. With such varied use , why not use IoT for law enforcement.

Let us look at the various places where IoT can prove beneficial.

Traffic Surveillence

In USA where you don’t have traffic cops at every junction, everything is digital. Cameras installed at street corners and street lights stop traffic violations by reporting everytime a rule is broken. Also, in delhi, during the Odd-Even rule it is practically impossible for traffic cops to survey each and every car to see violations of the rule. Therefore, a RFID tag on each car’s number plate and then RFID readers installed at traffic signal to detect and report violators.

Also, any accident (hit-and-misses for eg.) can be easily reported and taken care of immediately.

Preventing Theft

There was a time when cases of breaking-in at homes was popular but that has all changed now with Smart door locks and camera systems that identify whenever an unidentified person tries to enter, at the same time alerting the nearest police station. Home cameras which are internet enabled can also allow you to monitor your home remotely.

Also, most devices today have an associated IP address which can be easily tracked so if anytime a cyber crime like hacking into a personal system or a sophisticated bank software is detected, the device through which the same has been done can be estabilished.

Moreover, black money laundering is the one of the most prominent crime in today’s time. Through Smart Money, Black Money can be tracked easily. This was the idea behind Modi’s Demonetisation scheme. Also, bribes can be detected by tracking the movement of money that is programmed to reach a specific person. If the money does not reach the specified person, it alerts the sender.

Moreover, nowadays smart pendants or other forms of wearables for women with SOS button have become popular whenever the need to alert the authorities in case of danger arises.

City Surveillance

In this era where mass community lynching, protests , murders and vandalism prevail, IoT technology can help keep a check on this. Smart cameras installed at critical locations and street lights and important VIP junctures can enable in real time city surveillance using high end video analytics. The cameras have become smarter with technology such as fog computing or edge computing enabling the edge devices which notify local authorities when any mass protests or similar happen.


Even though the technology that we developed to make our lives easier is being sabotaged to create havoc, the same technology can be used to restore the law and order. Concluding on the same lines, IoT is the way forward for law enforcement.
