In lieu of a cost-effective, consumer-friendly home automation standard being available, products like the D-Link 3G Door Phone have emerged to address ad hoc automation needs. This suped-up, waterproof doorbell allows home owners to monitor the front door over a 3G cellphone or PC via the unit's integrated 0.1 megapixel camera, SIM card, speaker, and mic. Home owners can then see the visitor as a snapshot or over one-way 3G video while interacting over a two-way voice call. Unfortunately, it won't allow you to remotely unlock your door; for that you'll need something like a Schlage lock and a fussy Z-Wave network to go with it. Alternatively, devices like the Siemens Gigaset HC450 intercom has the option to control your electronic door lock from your home landline
