IoT consists of several functional components: data collection, transfer, analytics, and storage. Data is collected by sensors installed on mobile, end-user hardware like phones, robots, or health monitors.

Then, the mobile data is sent to the central cloud server for analytics and decision-making, such as if a machine requires proactive maintenance to prevent unexpected breakdown or if a patient needs to come in for a check-up.


According to the Boston Consulting Group, by 2020, companies will be spending around 310 billion USD a year on the Internet of Things, with much of this spent in the manufacturing, energy and transportation industries.

By integrating all of our modern day devices with internet connectivity, the IoT market is on pace to grow to over $1102.6 Billion annually by 2026.

The smart city is derived from the “Smart Earth” theme report released by IBM in New York in 2008, meaning that a new generation of information technology is used in various industries.

A smart city is an urban area that uses different types of electronic Internet of things (IoT) sensors to collect data and then use insights gained from that data to manage assets, resources and services efficiently.

Smart city spans a wide variety of use cases, from traffic management to water distribution, to waste management, urban security and environmental monitoring.

Its popularity is fueled by the fact that many Smart City solutions promise to alleviate real pains of people living in cities these days.

IoT solutions in the area of Smart City solve traffic congestion problems, reduce noise and pollution and help make cities safer.

Blockchain at its core is a cryptographically secured, distributed ledger that allows for the secure transfer of data between parties.

Traditional IoT systems are dependent on a centralized architecture. Information is sent from the device to the cloud where the data is processed using analytics and then sent back to the IoT devices.

Smart contracts in blockchain networks will allow devices to function securely and autonomously by creating agreements that are only executed upon completion of specific requirements.

Finally, with a centralized network, the risk of a single point of failure disabling an entire network is a very real possibility.

By harnessing the power of IoT for your security and surveillance solutions, you enable building owners, organization managers, and security professionals to:

  • Manage and control surveillance devices remotely to monitor all aspects of a facility.
  • Make smarter decisions about the best course of action to take based on real-time security conditions.
  • Determine when there is a false alarm without having to physically inspect the location or unnecessarily dispatch law enforcement.
  • Collect and analyze data to make important improvements to security processes and systems.


The IoT and robotics communities are coming together to create The Internet of Robotic Things (IoRT).

The IoRT is a concept in  which intelligent devices can monitor the events happening around them, fuse their sensor data, make use of local and distributed intelligence to decide on courses of action and then behave to manipulate or control objects in the physical world.
