Baby Monitors Tested for Range and Interference
Three video monitors checked room-to-room through walls and near common household interference sources.
Signal range through multiple walls varied more than spec sheets suggested across three video monitor units tested in the same two-story house.
One model dropped connection consistently near the household's wireless router, pointing to channel interference rather than a hardware defect — moving the receiver base resolved it.
Battery condition on the portable receiver units degraded differently across brands, with one holding a usable charge through a full overnight period and another needing a mid-night top-up by month six.
