Homeowner Using Security System with App

Both technicians were kind and knew what they were doing. Asked for all our needs and upgrades. Travis Wood and Luis Vega, great job.

Richie Crouch

We just upgraded our system and we are so pleased. Travis W. was extremely professional, personable, paid attention to detail, and was patient while training us how to use the system’s multiple features (many of which we didn’t realize were available). Travis went above and beyond not just yesterday during the initial upgrade, but also when he came back today to help us fix an issue and provide additional training. His quality was first-rate, and the customer support and service teams were also helpful. I would highly recommend NWOSS.

Angela Nickel

The technicians arrived promptly at scheduled time. Both introduced themselves, explained what they were going to do. Noah and Travis were very professional, courteous, answered all of our questions and didn’t leave until we were familiar with and understood the new system. Thank you!!

Amazing job by Travis and Luis. I was very pleased with their professionalism. They made sure I was comfortable with the system and functions and answered any questions I had promptly. If they needed to double check on something they did immediately so I had accurate answers. I will definitely recommend Northwest Security to anyone in the market for a premier security system.

Noah and Travis were professional and caring. The staff at Northwestern Ohio Security Systems are amazing. We had questions after the installation, and everyone was so willing to answer all our questions. We are so glad we chose NWOSS!

We just had a security system installed with doorbell camera. Kevin is really nice and explained everything and was so good in getting the install done perfect! We are happy to have chosen a local security company that has the best equipment and service! Thanks Kevin and Northwestern Ohio Security for everything!!

R. Hall

Kevin is a very nice, respectful, and friendly technician that is really knowledgeable about his job. He took his time to explain everything to my husband and I so that we understood the new unit that was installed. He showed us how to operate it step by step and answered any questions that we had.


We have had Northwest for many many years and needed to upgrade. Kevin worked with us on a system perfect for our needs. And very affordable! He was professional and kind and patient with our question over the new technology. We have always been pleased with the service we have received over the years. Always a fast response to any issues we have had. And they are a local business! Highly recommend them and love this new system!

Just a note of praise for salesman/technician Kevin, who is a phenomenal representative for your company. As a salesman, he is knowledgeable, organized and gently persuasive. As a technician, he is competent and confident. He creates a culture of trust. I found it very comfortable to work with him and greatly appreciate his communication skills and his expertise.
