The motorized barrier is the most common component at campsite entrances. However, in most facilities it operates independently of the management system: staff open it manually, or the guest has a fixed remote control. This means no access log, no automatic reservation verification, and no possibility of self-service access.
The three methods for integrating with the management system
1. Dry contact (the simplest)
All motorized barriers have a clean-contact input (dry contact) that, when closed for 100–500ms, simulates pressing the opening button. By connecting an IoT controller-controlled relay to these two terminals, you can open the barrier via software without modifying anything in the existing system. It is 100% compatible with FAAC, CAME, BFT, Roger Technology, and any other barrier with this functionality.
2. RS-485 / Proprietary protocol
Higher-end barriers (FAAC B680H, CAME GARD G6000, Roger MC200) support RS-485 serial communication with proprietary or standard Wiegand protocols. This allows you not only to open/close the barrier, but also to read passage logs, set access time windows, manage RFID tags on a blacklist, and receive alerts (barrier hit, motor error, low battery).
3. IP integration via API
More modern systems such as FAAC Connect or CAME Connect offer REST or WebSocket APIs for direct integration over an IP network. This is the simplest method to implement on the software side, but it requires the barrier to be connected to the campsite network (wired or WiFi).
Typical integration diagram
| Component | Role | Protocol |
|---|---|---|
| FAAC B614 barrier | Physical actuation | Dry contact or RS-485 |
| IoT controller with relay | Interface between barrier and network | MQTT to management system |
| MQTT broker (Mosquitto) | IoT message hub | MQTT 3.1.1 |
| Ovvo Camping | Business logic (reservations) | Internal API → MQTT publish |
| Management app (web/mobile) | Manual opening from reception | WebSocket → MQTT |
Access control logic
When a vehicle approaches the entrance (detected by a magnetic loop or presence sensor), the system checks:
- 1Is there an active reservation associated with the detected license plate (if ANPR is available)?
- 2Is the arrival date today or the previous day (authorized early check-in)?
- 3Does the time fall within the facility's check-in window?
- 4Has the guest paid, or do they have a reservation with payment on arrival authorized?
If all checks pass → relay closed → barrier opened → log recorded. If any check fails → barrier remains closed → alert sent to reception staff.
For nighttime, it is possible to configure a 'night mode': any vehicle registered as a guest can exit freely (exit always open for residents), while entry requires the RFID tag on the guest wristband.
