In addition our engineering department continually monitors the latest technical advances looking for ways to improve and enhance our existing products.

We encourage our customers to utilize our toll free “800” number for information requests, placing orders, checking order status, or technical support. Dortronics Systems field sales staff are independent manufacturer’s representatives, specializing in access control products for the Security industry. This group provides sales coverage for all fifty states; International sales are handled through the main office. Our marketing philosophy is to involve everyone from the top to the bottom. Both our inside sales staff and the field sales representatives are providing feedback from our customers as to what they want. From this information we develop new products and market programs. Dortronics exhibits the latest innovations in electronic security hardware at major security trade shows and seminars throughout the year.
