Detect doorbell and the wireless vibrator Pocket Vib work together to notify you when the doorbell rings. When visitors press the button on Detect Door, the signal is wireless transmitted to Pocket Vib which vibrates and lights up so that you are certain to be notified. 

PocketVib is wireless and can be carried around the home. Detect Door and PocketVib can be placed up to 75 metres apart. When the doorbell rings, PocketVib produces a powerful vibration and four LEDs are activated.
