Corded Summer video monitors are being recalled because of two strangulation deaths. There doesn't seem to be any specific issue that's unique to these monitors, and the recall doesn't correct anything really, just adds a new warning about placement of the monitor. More than causing concern about Summer monitors specificaly, this recall is a good reminder not to put anything with a cord too close to a crib.
