Third Eye are a friendly family company in ~London, an efficient and professional company to deal with. Had a visit from an engineer this morning (Alex) and his approach to customer service and relationships is outstanding. He is obviously very knowledgeable and goes to great lengths to answer questions and ensure that I understand how the system works (had a new panel fitted). I have no hesitation to recommend Third Eye. #Alarm​, #CCTV​ and #Security​ Systems London
