In the shower? On the Toilet? Want to avoid pesky sells people? The new iDoorCam ($127) lets you answer your door from your iPhone. You can see, hear and speak to the person at the front door from your mobile device. The camera is functional in the day or night, includes a speaker, microphone and a motion sensor. The iDoorCam does replace a current doorbell and works off of the voltage provided by the doorbells power source, so if you don’t currently have a doorbell an alternative power source will be required.
