We have found A.D.A. security to provide an excellent service both during and after the installation and any upgrades have been carried out in a discreet and very professional manner. Their workmen were neat, polite and always willing to explain the whole process or any problems associated with it. We would have no problem recommending them to any prospective clients.”

CCTV system in Killorglin


“…ADA installed a CCTV system in Killorglin in 2009 and have maintained, cleaned and serviced the cameras and control system since then. They initially trained the voluntary group of people who manage the system on behalf of the community. The KCCCTV Consortium have assisted the Gardai in many investigations by facilitating the requested for images to be download onto CD-Roms. Having dealt with them personally over the years I am delighted to endorse ADA as a dependable company and good communicators (it is easy to make contact and they are good at responding to queries and calls).”

Town Centre CCTV in Kanturk Co. Cork


ADA Security Systems installed extremely high tech security cameras in the town of Kanturk. This was a huge initiative for the town to undertake and we were very thorough on the company we wanted to secure this business as we were aware of the funds being invested were community funds. However, following consultation with ADA there really was only the one company we wanted to do business with. Their systems are of the highest spec. Their professionalism and enthusiasm is second to none and their willingness to help you and educate you on the system we have spent so much hard raised community money on is invaluable. All their engineers are extremely helpful and when installing the cameras in the streets of Kanturk it was done is a timely and neat fashion.”
