    Overall Satisfaction

    I purchased the Serene Innovations CentralAlert CA-PX Receiver/Pager
    HC-CAPX along with 2 Serene Innovations CentralAlert CA-AX Audio Alarm Sensor
    HC-CAAX and 1 Serene Innovations CentralAlert Notification System CA-BX Baby Cry Sensor
    HC-CABX I would not recommend this system to even a hearing person It is very inaccurate the pager has a very powerful vib lights noise which would be great if it was quick or had any form of accuracy by the time it picks up that your baby is crying they have been crying for a while and have to reach screaming portions for there gry s to be picked up no matter what sensitivity you set it on problem is baby call monitor gives false alarms bay crys shows house alarm house alarm goes off sometimes shows sometimes does not .
