Testimonials

  • Good service and fairly priced, plus what he does works! Chris has given us expert advice on security systems and installed and maintained those systems over a number of premises.

    Rick Flay, Property and Business Investor
  • We chose Crism for our security camera because we know and trust the owner Chris Mortimer. On the day of installation the team arrived on time, consulted us where the camera and the hard drive were to be situated and then got stuck in. There was a bit of drilling to insert cables but any dust was cleaned up. The camera is not obtrusive and gives a good picture.

    We are delighted with the end result and would be very happy to recommend Crism to others who are considering making their home more secure.

  • As we are expanding our business we have built a large new fitting bay to the rear of our existing property. We therefore needed a new security alarm system for this area.

    Chris at CRISM was recommended to us by our insurance agent (the best recommendation you can get really!) Chris at CRISM and his guys were fantastic, great at answering our questions and fitting our new system.

    We certainly feel safe and secure knowing that our building is protected by a first class security system. We would recommend CRISM every time.
