Do you want an additional camera for your baby monitor? Yes, that is indeed very practical! The Alecto DVM-781 expansion camera can be used in conjunction with the Alecto DVM-78 baby monitor. The baby monitor comes with one camera unit, but you may want to install multiple cameras in the nursery so that you can keep an eye on your child from all angles and corners. In that case, the Alecto DVM-781 is an excellent solution. You can monitor different cameras on the parent unit of your baby monitor with a single display, either sequentially or simultaneously. This is extremely convenient if your child occasionally sleeps elsewhere and you don't want to set up the baby unit each time. An additional device can also be useful if you have multiple bedrooms in your home. Most parents purchase an extra baby unit because they have siblings with their own bedrooms that they want to keep an eye on. The camera can be manually adjusted and is powered by an included power supply.
