The Alecto DVM-75C is an extra camera for the Alecto DVM-75 baby monitor. You expand the baby monitor with up to 4 cameras. This way you can monitor 4 different spaces (or children) simultaneously on 1 screen. You place the camera in the best position manually to keep an eye on your little one. The camera has an integrated thermometer so that you can easily read the temperature in the room on the screen.
