About Us

Intruder Alert Systems Limited specialise in providing high quality security services including intruder alarms, CCTV, access control and off-site monitoring with guarded response; both on a temporary and permanent basis.


The original company on which we’re based started back in 1975, so 2015 is our 40th year in the Security Industry.

Our business has stayed in the same family during that time, so although we now employ experts in various fields, at the core we are still a family business striving to provide the best possible service to our customers.

Our roots are in the Thames Valley, but several years ago we opened a branch in Southampton and now have customers across Great Britain and the Channel Islands. We love helping businesses both close to home and further afield.

Our team is made up of a variety of experts who are passionate about what they do. Find profiles of some of our key team members below:

Meet the team

  • Managing Director

Daniel Moseley

Managing Director

Dan is our ideas guru. 

With over 18 years of experience in the security industry under his belt, Dan decided to come back to the family business and head up Intruder Alert Systems.

It's his genuine interest in people that makes him so good at designing security solutions - he always takes into account what the customer needs. As well as completing industry training, he knows the industry through and through, so can always pick the best and most cost-effective products to use in a system. 

At home, Dan loves spending time with his three gorgeous kids and is a quiet chef on the side.

  • Engineering Genius

Chris Ball

Head of Engineering

Chris is a true electronics geek. 

Chris heads up our team of engineers, and with all his experience, is great at training our new recruits. He's completed his Tavcom training in Intruder Alarms (our industry standard) as well as having an Edexcel BTEC award in Intruder Alarms. He's got BFPSA BS5839 in installation and testing of fire alarms, fire detection design and fire alarm maintenance. Chris has also got various certificates in the operation and application of different products, so he understands our systems inside and out. And he can install and maintain everything safely, having passed the Construction Skills Health and Safety test. 

What our customers' love about Chris is that he's a perfectionist - you won't see neater wiring.

When he's not installing security solutions, Chris loves spending time with his family and enjoys bike rides.
