Grandpa is in poor health and doesn't want to live with the children. Is there any way to know his health and safety at any time?

1, the traditional way, the younger generation calls more, visits more, or visits in turn, or asks the neighbor's neighborhood Committee to take care of more;

2. The new method is to use some intelligent hardware products, such as Harmony Smart Camera, to monitor the elderly for 24 hours (although this word is not appropriate), and to keep abreast of the living conditions of the elderly through mobile phones. In case of special circumstances, the target camera will make its own judgment and send an early warning to your mobile phone. If it is inconvenient for the elderly to use the phone, they can also make two-way calls through the camera, which is much more convenient.
