Hmm, a doorbell clock doesn’t exactly ring a bell in our books (pun not intended), but we guess there was enough research done to justify the existence of the Remote Visual Doorbell Clock. What does this $39.98 device do anyways? Regardless of whether it is powered by either an AC adapter or a quartet of AAA batteries, it will provide additional notice whenever someone is at your door step (an alert watchdog would do equally well, but at least you don’t have to clean up after the clock). Each time the doorbell is pressed, the clock will play one out of 32 selectable tunes, lighting up and flashing crazily away for 10 seconds to boot just in case it is late into the night and you are listening to your favorite relaxation tunes with a pair of noise-isolation earphones. Works great as long as you remain within a 50 foot radius from the doorbell.
