This motion-sensitive door chime helps bring 23rd-century “Star Trek” gadgets to the 21st-century world.
Modeled after the communicator panels from The Original Series, the Star Trek Electronic Door Chime alerts you when someone crosses the threshold. Mount it next to your door on whichever side you prefer and choose from two sound settings: Door Opening or Red Alert. Push the button on the front to activate the Communicator Whistle sound.
The Star Trek Electronic Door Chime is currently $17.99 as part of ThinkGeek’s Black Friday sale, so head over to their website to purchase.
