Building automation system integrator protects continuous data flow with TOSIBOX®

OTI is currently integrating a series of new building constructions in Mexico City for an ambitious developer and property manager. One mixed-use building project includes a 22-story high rise office building with an offset, integrated 3-floor shopping center, and 12 floors of underground parking.

With the new building construction, the developer wanted building operations management to be fully integrated using the best equipment available on the market today. Systems needed to be scalable and long lasting as the IoT evolves and expands. Since it was a new building construction, the integrated building management system needed to be installed before IT was available on premise.

Most advanced controls today are IP-connected, and those IP addresses change frequently. Having dedicated public IP addresses in Mexico is expensive, typically upwards of $500 per month. And changing IP addresses can be difficult for Cisco-type IT systems to handle. Adding a layer of complication, since OTI is a U.S.-based company, it needed secure remote access to all of the building’s control systems.


Building automation systems integrators can now connect buildings with cybersecurity confidence and ease.

OTI created an integrated building automation management system fiber backbone that includes HVAC control system, electrical power monitoring, access control, water, and a unified user experience for monitoring and control using standardized technologies. In addition, CCTV and various other systems were to be integrated to the network infrastructure.

To solve the security and connectivity issues the OTI team came up against in Mexico City, the master system integrators utilized various TOSIBOX® products.

The TOSIBOX® Virtual Central Lock is installed in OTI’s cloud environment to provide the highest level of secure VPN access for building data to transfer to the Tier 4 data center, which contains distributed servers for redundancy, failover and additional security measures. The TOSIBOX® Virtual Central Lock also allows for agility and scalability as building data grows with building occupancy.

OTI is also using TOSIBOX® Lock 200s as endpoints for secure remote connections. Devices throughout the integrated building management system connect into the Lock 200s and can then be securely accessed over the Internet through a safe VPN.

Finally, TOSIBOX® Keys are used to complete the secure cycle of connection between building automation devices, computers and data centers.

In addition to the ease of use, TOSIBOX® provides award-winning cyber security for OTI and their customers at a level previously unseen in the building automation industry. From end-to-end communication to two-factor authentication, no fixed or public IP address and the latest encryption technology, Tosibox provides a complete cybersecurity solution for the OTI customer base. Finally, building automation systems integrators can connect buildings with cybersecurity confidence and ease.

”TOSIBOX® has allowed our team to work faster and more securely across international lines. Before using TOSIBOX® products, we were sending technicians to Mexico City once or twice per quarter just for routine maintenance. Now we can do all of that remotely without exposing our client or their data to any security threats, and we only have to transport technicians in cases of major problems, which thankfully hasn’t happened yet. The product line is versatile and up-time has been excellent.”

  • Routine maintenance can now be done remotely, reducing transportation costs of sending OTI technicians to Mexico City.
  • Commissioning in stages allowed some tenants to occupy the building while further commissioning was completed.
  • Scalable and future-ready solution ensures optimal efficiency for the long term.
  • OTI is providing the most secure solution available to clients.
  • Network availability and uptime has been excellent.
