The Philadelphia Connection

Philadelphia has featured in our perimeter security blog several times over the years. Our Technical Director Andy Moon has made several business trips to the city and has always returned with fabulous photos and interesting stories. Usually there's a historical link - we here at Advanced Perimeter Systems love our history!

Here are two previous posts about Philly which have a history bias:

Joan of Arc Statue
William Penn Statue

It's safe to say that Philadelphia made a big impression on Andy, so imagine the excitement when we discovered yet another relevant and meaningful link with the city. What is it? Bose.

Electronics has been a passion of Andy's since an early age when he built his first crystal radio set (age 14). It appears that a similar passion developed for a boy from Philadelphia during the 1930's. His name was Amar Gopal Bose.

At the age of 13 Amar would spend hours dismantling and fixing radio sets. Every day after school he would repair radios in order to help his father's struggling business. He studied at the famous Massachusetts Institute of Technology, achieved a PhD in Electrical Engineering and, as Dr. Bose, became a Professor there.

In 1964 he went on to found the Bose Corporation.

He once said that his aim had never been to make money, but by 2007 (aged 78) he was one of the richest people in the world. It was always his passion for research, learning and improvement that drove his ambition.

The first 50 years of the Bose Corporation makes for great reading - click here to access the page and scroll down to the second video clip where you can watch Dr. Bose talking about his childhood love of electronics. If you like train sets and tinkering with electronics you will love to hear the story :)

Stirling Castle In The News With A Royal Visitor

If you are a regular reader of this perimeter security blog, then you will already know that here at Advanced Perimeter Systems Limited we all share a passion for our homebase of Stirling. With a colourful and unique history and some wonderful surrounding landscape, there is something for everyone here. Two of our previous posts about Stirling feature some interesting detail if you want to read them:
Perimeter Security People With A Passion
Security For William Wallace

It is not every day that our beloved city features in the news headlines but this last week saw one such day. HRH Prince William (the Duke of Cambridge) visited Stirling and, in particular, Stirling Castle.

Here is Stirling Castle photographed by one of our staff on their way to work last winter

The purpose of Prince William's visit was to launch the Thin Red Line Appeal to raise funds for the Argyll and Sutherland Highlanders Regimental Museum as it faces an insecure future. It is hoped that the Museum's target of £4 million can be reached by 2019 in order to fund its redevelopment.

The Museum is located at Stirling Castle, hence why the Prince flew in there by helicopter to meet a variety of local people including schoolchildren and various dignitaries.

The Prince was clearly delighted to have been made patron of the Appeal and you can read more about his involvement on the Royal website here.

Not far from Stirling Castle across the River Forth and within sight of our own Head Office stands the Wallace Monument which was built as a memorial to William Wallace. Anyone who visits Stirling usually makes time to see the Monument. Prince William proved no exception!

Even though he did not have time in his schedule to see the moument on foot, the helicopter carrying him back home after his visit to the Castle made a point of flying right past it. Undoubtedly, the Prince enjoyed his 'bird's eye' view :)

Kilovolts & Kilohertz To Kuala Lumpur

Today we progress our 'A-Z of Perimeter Security' series and consider the letter K.


How the term relates to perimeter security needs a little explanation. First of all, a Kilovolt is equal to 1,000 Volts. A volt is the derived unit for electric potential and was named after 18th century Italian physicist Alessandro Volta who invented the first chemical battery. For a more detailed, scientific description and definition please click here.

In order to operate correctly, an electric security fence has to carry a voltage. Our Electro-Fence™ has a maximum voltage of 10Kv (10,000 Volts) which is pulsed once per second.

Electro-Fence™ 10Kv electric security fence
 This high voltage pulse actually lasts for less than one thousandth of a second and our specially manufactured Electro-Fence™ Controllers (manufactured to exceed worldwide standards: BS EN ISO 60335-2-76 and BS1722 part 17) ensure premium, safe performance. As a result our electric security fence system has an impeccable safety record.


Kilohertz is a measure of frequency equivalent to 1,000 cycles per second. When it comes to perimeter security, we make most reference to the term when talking about another of our products: Microguard™ microwave detection sensors. Microguard™ has a modulating frequency of 1.0kHz, 1.28kHz, and 1.324kHz. More technical information is available on the Microguard™ pdf download.

Kuala Lumpur

Moving away from the scientific and technical arena, we thought Kuala Lumpur deserves to be mentioned in this part of our A-Z of Perimeter Security. Over the years, our Technical Director has visited Malaysia a number of times and on each occasion has brought back with him some memorable photographs. Many of them have been featured in this blog with accompanying stories. Here are a two of our favourites ....
