How smart should it be?
This depends on the situation
Would you like to retrofit an existing property or do you manufacture for new constructions?
In an existing property, wireless sensors are suitable for monitoring. The advantage is that they are easily retrofittable, quick and cost-effective, hardware independent and do not require structural changes.
In new construction, you have every possibility. Wired solutions are suitable here. Whether drives for automatic operation or wired sensors for window and door monitoring – these require power connections to deliver their power transmission. They need to be planned in advance before walls are plastered. Of course, you can also combine wired hardware solutions with wireless sensors.
