A number of years ago I had Dytronix install a camera system for me. It has been working very well and the inital installation went flawlessly. I have been very happy with the system Dytronix installed. I have recently needed some help & called Dytronix support center. All I can say is that the experience was great, Dytronix support staffs were very helpfull and solved my problem right away. I just wanted to thank you for Dytronix great customer service.
