Serious about business security

If you are serious about business security talk to us, we have been providing turn-key solutions to our customers for over 25 years and always take a long term view in ensuring the equipment we offer is robust with an acceptable life cycle.

CSS do not operate in the cheap and cheerful market; the products we source from our supply chain must be rigorously tested and be of a substantially high quality. In fact there are hundreds of our systems that are over 20 years old and still in good working order.

Providing quality security for your home

CSS are the market leader in the supply and installation of new generation intelligent security systems for both the business and domestic markets in Scotland.

Most new generation intelligent CSS security systems link to our 24h hour alarm receiving centre. When we receive a confirmed alarm we will notify the Police service and a nominated key-holder to attend your home.
