safe sleep environment to reduce all infant deaths [9] . The recommendations include supine positioning, use of a firm sleep surface, breastfeeding, room-sharing without bed-sharing, routine immunizations, consideration of using a pacifier, and avoidance of soft bedding, overheating, and exposure to tobacco smoke, alcohol and illicit drugs. Although no cause has been determined for SIDS or ”cause unknown” deaths, accidental suf- focation and strangulation in bed is known and is somewhat able to be monitored. Furthermore while monitoring cannot be proved to prevent death from SIDS and cause unknown monitoring certainly will not harm the infant and may prevent the infants death. Knight’s Wireless Baby Monitor will help ensure some of the sleep- ing environment hazards are brought to the attention of the immediate caregiver through monitoring. The monitor will also protect the child by alerting a caregiver within seconds if the baby stops breathing. This new design will combine features offered by individual wireless baby monitors into one compact self-contained monitor located at the head of the babies crib. The monitor will incorporate video, audio, temperature and motion monitoring to combat accidental suffocation and strangulation in bed. Any significant deviation from a normal parameter will set off the alarm alerting the immediate caregiver and alert the parents by text messaging their smart phone, the latter being a feature not commonly available in today’s monitors. Video, audio and the temperature of the infant will be accessible through the smart phone. The smart phone application will also control the monitor remotely allowing the system to be turned on and off. The system will further allow constant surveil- lance of the infant through web-enabled smart phone technology irregardless of the parents location. This device should bring peace of mind to any parent that uses it. This project includes research of baby’s sleeping habits, physical activity during sleep, and monitoring development specifically for the safety for
