I have an 8 month old and my baby monitor has broken im looking to find a camera one, however my 6yr old has started sleep walking so I'm looking for a dual camera (they're in separate rooms) so I can keep notified when they both wake up during the night. Has anyone found a reliable one... I need the battery to last all night on the cameras/Monitors would prefer them all to be wired so I don't have to replace batteries. Can charge throughout the day if needed.
