Public IP access can be convenient, but VPN and private access are normally safer for cameras, routers, BMS panels and gateways.
The practical answer
The right choice depends on the application, security requirement, support model and site conditions. Avoid one-size-fits-all decisions. Build the network around the equipment and the people who need to support it.
What to compare
- Reliability and uptime
- Security and remote access
- Installation complexity
- Data usage and SIM behaviour
- Long-term support and management
