Over the past few years, Colin at SDN CCTV has fitted two CCTV systems and several security lights for us. He is prompt, professional, and courteous, and we have been very happy with the system and his service.

After moving to Northern Ireland I was anxious about finding a new dentist. My wife recommended Mullan Gallagher, so I joined the practice and am very happy I did. The staff are friendly and professional, the facilities are top-notch, and my dentist and the assistants I've seen have been excellent.

We contacted SDN CCTV to inquire about having a small (4-camera) CCTV system and motion light fitted. The quoted price was very reasonable, they arrived on-time and fitted everything as planned, and there were no surprises. I'm very happy with the end result and can recommend SDN with absolutely no reservations -- I will use them again if the need should ever arise. From start to finish, they were very easy and pleasant to deal with.
