CCTV Installation
I didn't use this contractor, as a member of my staff,s boyfriend is an installer and did it for me. But I was delighted with SDN enthusiasm in contacting me. Had I not found the installer I used through a staff member I most certainly would have contacted SDN as I was impressed with what I seen. Adrian More...

Burglar, Security & Intruder Alarm Installation
Colin contacted me shortly after making an inquiry on-line using a search engine to obtain an alarm installer in the Belfast area. He was very pleasant to deal with and fully explained the type of alarm which would meet my needs. The price he quoted for the supply and installation of the new home alarm was very competitive and he's coming the day after tomorrow to fit the new alarm. From my dealings with Colin so far I've been very impressed and would highly recommend this company. More...
