Have a look at this
review which describes a remote control for your DSLR camera, but unlike most wireless remote controls, it also provides you with live video from your camera's viewfinder.
This works for DSLR’s that do not have Live View as well as those that have it. No wires to trip the shutter, or trip over, as well as the capability to view the live image on a small monitor.
