Who we are
As the SOLE System brand and Gray Teknoloji Sistemleri Danışmanlık San. ve Dış Tic. Ltd. Şti., it has always been our vision to keep pace with advancing technology and to continuously follow customer demands in order to offer the most suitable product and price for their needs. Building long-term relationships with our customers through quality service and a friendly approach is our primary company goal.
Structured around broad knowledge, experience and accumulated expertise, our company chose specific areas of specialisation and, over the years, has focused exclusively on these fields — achieving a number of firsts both in Turkey and in projects abroad. Gray Teknoloji Sistemleri holds all official distribution and installation rights for the Sole System brand across Turkey.
By the numbers
Our areas of expertise
For many years we have stayed focused, working only on vehicle identification and access control technologies. Today our areas of expertise are:
Vehicle License Plate Recognition Systems
Automatic plate-based vehicle identification, authorisation and barrier integration for parking facilities, factories, residential sites and public buildings.
Boom and Rising Bollard Barrier Systems
24V/220V boom barriers, rising bollards, sliding gate operators and field control panel solutions.
Public Transport, Smart Card and City Card Systems
Electronic fare collection, smart card and city card infrastructure for buses and public transport vehicles.
HGS / OGS Vehicle Identification
Tag reading at motorway and parking transits, with hybrid setups that work alongside license plate recognition when required.
Card-Based Time Attendance and Access Control
In-building access management with staff time-attendance tracking, card-operated turnstiles and door access systems.
Fingerprint Time Attendance and Access Control
Staff tracking and authorised-area access using biometric fingerprint verification.
AI-Powered Custom Software
AI-based recognition and reporting software developed through years of work to meet real field requirements in Turkey.
Our vision
Our vision is to closely and continuously monitor developments in our sector, so that our customers can reduce their company costs through correct and timely technology investments — and see those investments return to them as fast, timely information.
Our working principle
In line with our company principles, rather than simply supplying the device a customer asks for, our expert team determines the device, software, equipment and price that will genuinely suit that customer best. Our aim is not to sell a product but to deliver a complete system solution matched to the real needs of the site — so that you get the full value of your investment.
The products we use and our quality approach
Every component we deploy in the field is selected to run continuously for years in outdoor conditions. Alongside our own Sole System product range (24V/220V Mass Pro, TekPlus and MTC series boom barriers), we also choose globally recognised brands such as the Italian BFT Moovi and GIOTTO barriers where a project calls for it.
In our control panels we use professional hardware such as industrial or semi-industrial PCs, uninterruptible power supplies (UPS), PoE switches and relay cards, bringing every field device together on a single TCP/IP network. Systems that have run without interruption for 3-4 years in Gebze and for 7 years in Istanbul are the field proof of these hardware and architecture choices.
Technical support and service
It is extremely important to us that our technical support and service staff — each an expert in their field, with knowledge continually refreshed through training — reach our customers quickly and on time to ensure satisfaction. From pre-sales consulting through to post-commissioning, you continue working with the same team.
