I first met Andy Ayers on a call out to fix my security alarm, that was supplied by another company, that kept going off in the middle of the night. He came out within 30 minutes and fixed it for me. While he was there I asked him to quote me for a new CCTV system to replace the ageing setup I already had.His quote was good so I said yes and he professionally installed new cameras which I am very pleased with. I can honestly say Andy is the most polite, well mannered and helpful tradesman I have met and that's quite a few after building two houses and a Barn conversion. I can thoroughly recommend Trojan Technologies. Barry S. Lower Woidrow, Melksham, Wilts.
