Description
audio door phone, this Wired Doorbell Security System can let you hear a person calling at your door before you open it. The Doorbell Intercom Security System all appears to be ingenious. When a visitor–wanted or unwanted–approaches a house on foot or in a vehicle the motion-detecting sensor unit of this warning device sends a signal to the receiver indoors which chimes an alert.
The Non-visible Doorbell Security System makes it easy to replace your home’s generic doorbell ring with a chime tune that better fits your individual style.
You’ll love this Wired Doorbell Security System.
