The sent a text and called my phone saying an alarm went off. I was in the shower and couldn't answer. They Sent the fire department. I'm trying to follow up with them to find out what is wrong and they dont answer their phone. Pushed every button. No answer. How is that possible that they dont have the man power to take calls? Its not the first time. It is outrageous. Ive also had a really bad experience with their billing. Once you sign the annual contract, you are NOT allowed to cancel your service without paying the full contract. And that was despite them changing my monthly rate and over charging me. They have done a good job buying all of the competition and terrible awful service.

It does excellent work from top to bottom, starting with my salesperson, Bob Haff. I can reach him right away & he's so helpful. Other great folks there are Mark, the tech, Curtis, the owner, Jose, a manager, and office staff who always get back to me promptly. To me, Systems Design is the premier alarm company in the Southampton area. In many homes you need both wired alarms and wired cameras and this company does it all. Systems Design provides customer peace of mind, great service & trust, a first for me.

I had a security camera system installed by Michell over 10 years ago and I recently started having…read moreissues with the recording and playback. He suggested we troubleshoot over the phone before sending a technician to my house. Since the equipment is old, he had to send a technician after all. While I was waiting for the technician to arrive, I fiddled with the settings and ended up resolving the issue on my own. What really stood out to me was the honesty--both Mitchell and the technician could have easily said I needed new equipment or upgrade or unnecessary work, but instead they were supportive and completely upfront. Very fair, trustworthy, and refreshing to deal with a company that operates with integrity. Highly recommend for your security needs!
