      Great effort today to have this installation finished and handed over In a day. Always going that extra step to make the job neater and discreet. Again choosing the correct colour cameras for the surface they are mounted on, same for the alarm door contact. Using a grey case on grey. Also digging and burying the cables in containment. All in all customer very happy with the teams efforts and work. ... See MoreSee Less

      Some of our feedback!


      "Very pleasant. Gave us some options and a very fair, competitive and realistic estimate. Cost was exactly as quoted. Really respectful of our property. Arrived on day and time expected. Worked very hard all day. Cleared up after themselves. Delighted with the quality of work done." - Customer in Enfield July 2020

      "Sam and Jack were very knowledgable in their trade. Fitted my new CCTV cameras within a few hours and they did an amazing job. I will be recommending them to friends and family, and will be using them in future. They even went out of their way to come back on a separate visit to show me how the app works on my phone. Thanks CSI!" - Customer in Chigwell June 2020

      "Fantastic service from both Jack and Sam at CSI can’t fault their workmanship. Excellent communication and took the time to describe exactly what they were doing and they advise on what would be best for our property and requirements. The quote for the work was great and no hidden costs added. Time was taken to explain the setting and unsetting of the alarm and the settings on the CCTV system. Cannot recommend CSI enough. Thank you" - Customer in Hoddesdon June 2020

      "This is the second time we have used CSI - at our last property to install CCTV and at our new property for CCTV and an alarm. Both times they were quick to respond to queries, were professional and friendly on the day and carried out high quality work in good time. As mentioned, we have already used them twice so wouldn’t hesitate to recommend or using them again ourselves if we needed to." - Customer in Witham May 2020
