One-time hardware
Controllers, border routers or bridges can be shared across many devices.
Recurring services
Cloud recording and premium features may add monthly cost.
Consumables
Battery-powered sensors create an ongoing maintenance and replacement cycle.
Lifecycle cost
A product with longer support and good interoperability can be less costly over time than a cheaper isolated device.
Keep in mind. Compatibility is not permanent. Confirm the current manufacturer, platform and certification information before purchasing, resetting or migrating a device.
