Fix of alarm system
We had an alarm go off on an unused burglar alarm system due to a dead battery. Colin came out, put on a new control panel, re-wired and re-configured the system and zones and spent some time with us going through the instructions.
Excellent and professional service and at a great price considering that it was a time-consuming job.
I love my new cameras. I feel more relax being away from home knowing I can view my property through my phone! The cameras have a great picture day and night, and the prices are so reasonable! Overall I am so pleased with the serivces I received, highly recommended!
I will know be able to go on holiday and relax as i know i will be able to view my house from a mobile phone or a tablet. I was given one to one information from the installer on the workings of the cctv software which was really helpful. The quality of the picture day and night is very clear. Overall a great friendly and professional service. Highly recommend
SDN have provided me with an excellent and professional service, leaving me with added security and piece of mind. I dealt with Colin who was incredibly knowledgeable and went out of his way to ensure that my system was tailor made to suit my needs. I am more than impressed with not only the quality of the service but also the quality of the system! The CCTV camera images are incredibly clear and I can even remotely view them via my phone or computer which is just what I wanted. I'm not the most technically minded person in the world but even I found it all a breeze once Colin had finished explaining how everything worked, I regularly find myself checking in on my property when I'm away from home which is great for piece of mind. It was a very tidy and professional installation and I would definitely recommend SDN to homeo
