Intercom & doorbells
Wireless doorbell kits: range and interference
Wireless doorbell kits fail when range claims ignore walls and interference. Set expectations and stock reliable pairings.
Range realism
Publish typical indoor range, not empty-field marketing metres.
Concrete and metal doors reduce performance.
Pairing and power
Battery types and push-button IP rating should be clear.
Offer plug-in chimes where needed.
Merchandising
Sell as complete kits; spare buttons are useful add-ons.
NMF packs kits to survive parcel and container handling.
