I'd second David's point, I've been using a video sender for about a year - it has good days and bad days for no apparent reason, but is generally watchable/listenable: However, some of my cottage walls are 3 ft. thick, which doesn't help.

The one I have is, One-For-All: I previously tried one that appears in the UK under a number of brands with a saucer like aerial - that didn't work at all well (But was half the price).

The phones don't cause a problem, but certain functions on my Linksys wireless network interfere with it: It's hard to define what, but it seems to be for fairly short periods, so I put up with it.

I also have wireless doorbells, and the curiosity is that one of them rings when I reboot one of my P.C.s! - A problem at 4.00 a.m.
