This Nuclear Doorbell triggers a very loud siren, flashing yellow light and ‘booming voice’ whenever anyone presses your doorbell button. Yeah, so you’re probably not going to get a lot of repeat visitors after installing this sucker, which you may think is A Good Thing. Your postman, on the other hand, may not. £15.95.
Stick the buzzer to the outside of your front door and the doorbell to the inside and wait. The deafening siren, flashing yellow light panels and booming voice will put everyone in the area on full Red Alert. Doorbell ringing will never be the same again!!
