The easy-to-set-up and use KX-HN3001W Baby Monitor is designed with the same powerful Dect technology built into Panasonic's long-range home telephone systems for a clear, secure and interference-free signal strength up to 1500 feet*. More than the length of four football fields and twice the range of comparable monitors. Anywhere in or outside the home you can clearly and continually keep tabs on the child. The KX-HN3001W Baby Monitor system includes a bright 3.5-in. color monitor and controls that sync to the wide-angle, wall-mountable monochrome night vision camera in the baby's room (the KX-HN3001W system is expandable up to four cameras). The camera can be controlled to pan, tilt and zoom the camera right from the monitor to look in on the child anytime. A long-life, built-in rechargeable battery in the monitor stores power for up to 13 hours of standby time and up to 5 hours of power for continuous use. Sensors for motion and sound can alert you when the child is awake or stirring, and when they are talking or crying. Smart sensor options make it easy to customize sound and motion notifications to suit parent needs and preferences. Another sensor alerts parents automatically when the baby's room environment goes above or below temperature. Microphones and speakers in both camera and monitor enable 2-way talk with the child. Gentle, soothing sounds calm and relax the baby with a choice of lullabies and five types of white noise.
