I was tasked to compile advice on CCTV systems for a range of individual properties on our estate... From the outset, CSN impressed with the prompt initial contact from their office, followed-up with informative face-to-face meetings with an engineer, and even installed a demonstration system on my own house to show any other interested residents what could be achieved. No other company came close to this level of involvement. As a result, several residents sought detailed quotations for CCTV to their individual specifications, and not only did we subsequently install a CSN system on our own property, but to my knowledge 3 other residents at this time have also elected to install CSN systems. CSN staff provided technical advice in a friendly and supportive manner and recommended equipment to meet our requirements at a price that was competitive. Their installations were carried out to a high standard on an agreed timetable. I therefore have no hesitation in recommending them.
