Review on Wireless Caregiver Pager Smart Call System - 2 SOS Call Buttons/Transmitters, 2 Receivers - Nurse Calling Alert for Patient Help - Home/Personal Attention Pager with 500+ Feet Plugin Receiver by Eric Webbie

This is a security product that allows the patient to communicate with the caregiver remotely. Call buttons are battery operated. However, I have not been able to find out how the nurse knows that the batteries in the call buttons need to be replaced other than that they no longer work. It would be like a fire alarm that wouldn't tell you to change the batteries and you'll know when the house is on fire and the alarm won't go off! Even a random check from time to time does not solve the problem. Since you can't know when the batteries are low, it may work well one week and not the other. It's not safe. The patient can signal that there is a problem without the caregiver being aware of it.
