While they may enjoy the job a lot, the one task that parents have to contend with keeping watch of their babies. Actually this is not a difficult job but only if they do not have to do anything else at home. There are other chores to attend to, from those that involve the use of the kitchen to cleaning the home.
When there are more cameras that are used to monitor a baby the parent can naturally see more angles of their baby who is left in his room. A couple of cameras, on the other hand would be needed if the parents would like to have views of two children in separate rooms or locations. However, most baby video monitor sets only have one camera included.
