 Why Choose Us?

Marnies offers a professional, personal approach to alarm systems and maintenance and we are proud of our enviable reputation for great service.

Great value – we install high-tech, easy-to-use burglar alarms, CCTV, access control and gate automation, as well as many other specialised security systems without fuss and unobtrusively. We have custom-designed security systems for homes and business premises; large corporates, multi-million rand luxury homes to granny’s little cottage in the back garden.

We also specialise in alarm servicing and maintenance contracts. Many of our customers prefer Marnies to service and maintain their alarm systems.


Whether you need home security or for your business, talk to someone whose first priority is your security. Our free, no-obligation site surveys are carried out by a security expert – not a salesman.

After discussions, we will recommend the best system for your particular application. Call us for a free, no-obligation quote.


 Home security must be taken seriously, especially given today’s crime statistics. As people get desperate and some turn to crime, it leaves our homes, businesses and families easy targets. Take action and be pro-active. Marnie’s can help, from our courteous and knowledgeable support staff to our well-trained, permanently employed technicians. It is owner run by Tony and Lee Marnewick.
