Got my alarm system fitted by Lenz and absolutely over the moon with it. I can set and disable my alarm from my phone and call the police if needed. Very competitive price compared to other firms and the service is second to none.
Would definitely recommend plus I know they do camera systems which can be integrated with the app you can get on the phone. It all works with your wifi and is easy to setup. They work very efficiently and have helped me move my alarm system from one house to another completely hassle free and at short notice. 10/10
