Outstanding Support

We're known for our direct relationship with our customers. Our support staff is second to none in providing live, ongoing, individualized support for each of our clients. SSI support is first facilitated by a sales engineer who will answer all your questions and educate you about the entire installation and system implementation process. Once a solution is in place we make sure you know how to use it effectively through our training, service, and even a post-sale follow up to be sure you are completely satisfied with the solution we've implemented.

We have a reputation for not leaving until we're told to, affirming our commitment to ensuring the client is fully competent in operating the system they have chosen.

Expert Staff

We employ only the most qualified candidates for positions here at Security Source. Even our sales staff are fully certified in the products we carry and service. Because of their unique certifications we call them Sales Engineers as that title is the most accurate description of what they do. When you speak to a Sales Engineer you can be confident that you're speaking with someone who can address all of your questions and concerns however technically specific or vague they are from pricing, to logistics, to planning, installation, and more.

Quality Above All

At Security Source we don't volume sell or try to get you to purchase more or less than the design plan calls for. We believe in providing our clients with the highest level of support and the solutions that best fit their needs. System Integration is a key component of our offerings. Regardless of the existing environment as it relates to existing hardware, software, or other infrastructure, our goal is to maximize and integrate every resource available to design a system that provides the exact solution you need. We know that migrating to a new system can sometimes be a hurdle to operator efficiency. That's why we make sure you and your staff are educated in all end-user capabilities of your new system thus maximizing performance and operator efficiency.
