Smart monitoring for secure fuel storage
Always-on connectivity for fuel storage sites, so tank sensors, cameras and access control report to a central team.
The challenge
Fuel storage has to be watched all the time: tank levels, leaks, temperature, cameras and who opens which gate. Many depots are outside towns, where wired links are slow to arrive or unreliable.
If the link drops, the monitoring team loses sight of the site, which is a safety and a loss-prevention risk.
How Nexapp solved it
Cellular links that stay up
Instaroute 4G and 5G routers with dual-SIM failover between two operators, and outdoor IP65 units that mount where the signal is best.
Speaks the site's protocols
RS232/RS485 serial ports, a Modbus RTU/ASCII/TCP gateway, DNP3, IEC 60870-5-101/104 and MQTT, so existing controllers and meters connect without replacement.
Cameras and sensors kept apart
Zone firewall and VRF segmentation keep CCTV, sensors and office traffic in separate zones, so one compromised device cannot reach the others.
One console for every site
Instaroute SDWAN Lite 2.0 shows the health, signal and data usage of every router, with zero-touch set-up and canary firmware rollout, wave by wave.
What changed
- Tank, sensor and camera data reaches the central team continuously.
- A failed SIM or operator no longer means a blind site.
- Sites are added without an engineer configuring each router.
Planning something similar?
A Nexapp engineer can walk you through this deployment and map it to your own sites, links and devices.
