My beautiful daughter was home alone when two years ago she had her seizure. Previously she was able to call for help but not that time. She survived but she is paralyzed and not able to speak. To keep her safe I have to always keep an eye on her, including her sleeping next to me. Then I learned about SEMi device and since it arrived it has become my best helper. The camera works wonderfully, I can adjust settings to alert me day and night. Through the monitor, I am watching my daughter resting and I am able to do things in the house that I wasn't able since she is paralyzed. It's a wonderful device and I am deeply grateful for the developers of that system. It's a life-saving device and I highly recommend it to anyone who has to deal with epilepsy to acquire SEMi.
