“I have used Ollie at Third eye installations for loads of my properties. The customer service and professionalism is second to none. I would highly recommend this company.”

Russell Carter

“Alarm and three cameras Ollie did a great installation with clear instructions for use on phones via the app etc. The after service has been great and ongoing support for silly questions, battery changes etc has been second to none. Would not hesitate to recommend.”

Nick Scott
