Matthew Poole, Iknaia’s Director of Technology, Connector of Objects and Systems Architect, has published his first book.

Written in an easy-to-follow conversational manner, it will show you how to build your own sophisticated modular home security system using the popular Raspberry Pi board.

 

 

 

About This Book

  • This book guides you through building a complete home security system with Raspberry Pi and helps you remotely access it from a mobile device over the Internet
  • It covers the fundamentals of interfacing sensors and cameras with the Raspberry Pi so that you can connect it to the outside world
  • It follows a modular approach so that you can choose the modules and features you want for your customized home security system

Who This Book is For

This book is for anyone who is interested in building a modular home security system from scratch using a Raspberry Pi board, basic electronics, sensors, and simple scripts. This book is ideal for enthusiastic novice programmers, electronics hobbyists, and engineer professionals. It would be great if you have some basic soldering skills in order to build some of the interface modules.

What You will Learn

  • Understand the concepts behind alarm systems and intrusion detection devices
  • Connect sensors and devices to the on-board digital GPIO ports safely
  • Monitor and control connected devices easily using Bash shell scripting
  • Build an I/O port expander using the I2C bus and connect sensors and anti-tamper circuits
  • Capture and store images using motion detectors and cameras
  • Access and manage your system remotely from your mobile phone
  • Receive intrusion alerts and images through your e-mail
  • Build a sophisticated multi-zone alarm system

In Detail

The Raspberry Pi is a powerful low-cost credit card sized computer, which lends itself perfectly as the controller for a sophisticated home security system. Using the on-board interfaces available, the Raspberry Pi can be expanded to allow the connection of a virtually infinite number of security sensors and devices. The Raspberry Pi has the processing power and interfaces available to build a sophisticated home security system but at a fraction of the cost of commercially available systems.

Building a Home Security System with Raspberry Pi starts off by showing you the Raspberry Pi and how to set up the Linus-based operating system. It then guides you through connecting switch sensors and LEDs to the native GPIO connector safely, and how to access them using simple Bash scripts. As you dive further in, you’ll learn how to build an input/output expansion board using the I2C interface and power supply, allowing the connection of the large number of sensors needed for a typical home security setup.

In the later chapters of the book, we’ll look at more sophisticated topics such as adding cameras, remotely accessing the system using your mobile phone, receiving intrusion alerts and images by email, and more.

By the end of the book, you will be well-versed with the use of Raspberry Pi to power a home-based security system that sends message alerts whenever it is triggered and will be able to build a truly sophisticated and modular home security system. You will also gain a good understanding of Raspberry Pi’s ecosystem and be able to write the functions required for a security system.

Building a Home Security System with Raspberry Pi, is now released and available to purchase on Amazon and also on the publishers Web Site.

 

Iknaia Launches Airscan with Colas

AirScan-App-and-HardwareOne of Highways England’s key objectives is to provide road users with information that is relevant to their journeys. Smart motorways are an obvious example and now, thanks to pioneering work from leading transport infrastructure specialist Colas Limited, information on travel times through roadworks is also available in real time. This means drivers are better informed, improving their experience and thereby reducing the risk to road workers of hazardous driving.

Automatic number plate recognition (ANPR) can often be utilised to track the progress of vehicles, but with diversion routes that may vary in location and route on a nightly basis, its use is not always practical nor cost effective. Colas has worked with wireless systems technology experts Iknaia to develop a system that allows the real time active management of diversion routes without recourse to ANPR technology.

Airscan is a new system developed jointly by Colas and Iknaia which uses anonymous Wi-Fi and Bluetooth signals transmitted by visible devices in passing vehicles. Data is collected by sensors and relayed to variable messaging signs (VMS) which then advise road users in advance of potential delays and allow for strategic checks by maintenance teams. As part of the system, Traffic Management (TM) teams are also issued with Bluetooth Low Energy (BLE) tags that can be used to monitor the location of teams by checking in staff as they pass sensors on their route.

26.10.2015_prRyan Wood, Colas Technical Manager, is key contact for the project and has been responsible for its initial trial at Highways England’s M3 smart motorway upgrade, for main contractor Balfour Beatty. “We are committed to delivering innovation on our highways projects and, through our work with Iknaia, we believe that Airscan is a solution that will not only benefit road users through real-time updates on traffic, but will also assist in improving the safety of our road workers.”

This approach to active management of diversion routes will continue to operate on the M3 smart motorway project and will be rolled out across other Highways England schemes to complement Intelligent Transport Systems strategies across the UK.
