The Philips Avent Premium Nanny Video Monitor provides peace of mind with clear picture and sound quality. It features a 3.5-inch display, 4X magnification for a closer look, and night vision for round-the-clock monitoring. The two-way sound allows you to soothe your baby from another room, and the built-in lullabies can help them drift off to sleep. It also includes a room temperature sensor to ensure a comfortable environment for your little one.
