Testimonials

The guys arrived on our agreed day/time, were very punctual, extremely polite and professional. Once all the camera were installed (in surprisingly quick time) the cleaned away quickly so they could explain very careful how to operate the camera system. Installed the system and included an app on phones for use too. They are very competitive on price, very professional, extremely good at what they do!!! Wouldn’t hesitate to recommend them to anyone!

There is nothing like putting a security system to the rest by having some ****s ram raid your business property…yup that’s what happened and the test was passed with flying colours.

Alert time was excellent and the siren was so loud they just left pretty much empty handed. Home system next and get the family protected please guys

Highly recommend.

We've been using Lenz for the servicing and line monitoring of our security system of a public building in the town centre for about 2 years. Having just had a visit today to tweak the system I was moved to write how professional, responsive and friendly the service is - as well as jargon free. They are also a very honest bunch; we mistakenly paid an invoice twice and the overpaid money was back in our account with about half an hour of letting them know.

Really nice bunch of guys who are very responsive. Installation was seamless (very inventive in hiding cables) and then follow up really good. Cameras have been up for over 2 years now and I still look at them every day.

Lenz security recently took over the management of our home alarm system. They improved on the current set up, adding additional sensors, which were not covered by the original installation. In addition, they consulted on and installed a CCTV system. All of this was connected to secure apps so we can access and control the system from anywhere. Their approach and communication has been excellent throughout the process. We felt sure that they were knowledgeable, and attentive to our requests, explaining everything we needed to know. There installation went smoothly, and was free of mess. The new cameras and sensors are discrete. What's better is that they installed the additional features for less money, with more equipment than the original company offered. Their ongoing support package is significantly cheaper than the original company. Overall, a great service from a local company.

Lenz security installed a system in our new build house. Andrew gave clear and well-explained advice about what would be appropriate, considering our lifestyle and family arrangements in his guidance. He took time to explain how to manage the system, and even came back to tweak the settings when asked. Polite, professional and helpful, I would happily recommend this company. Great service. Since being installed, I have been equally impressed by Andrew’s aftercare, which has proven even better than his excellent initial service. On a couple of occasions I have contacted Andrew with small queries, all of which have been answered almost immediately, no matter what the time of day or night. Lenz Security should be rightly proud of its 24 hour service.
