First, alleviate the loneliness of the elderly.
Nowadays, the social rhythm is extremely fast, and people are always busy, especially young people, who are not only busy with work, career and study, but also have no place to work. Young people in rural areas, in particular, are traveling from south to north, or far away from home in the east or west, living without a fixed place and working hard in other places. This makes many old people miserable. Walking in front of my hometown in the countryside, I can see the old man's face at a glance. They stayed at home and spent their old age alone. Chatting is between old people. Children and grandchildren are full, but they can't linger and ask for warmth. Then, if there is monitoring, wanderers far away from home can see the dynamics of the elderly in time. When they are free, they can often watch the elderly chat and say a few warm words to each other to report peace.
In this way, the loneliness of the elderly in their hometown will be greatly reduced. With spiritual comfort, they will be happier, richer in their old age, in a good mood and in good health.
Second, you can see the physical health of the elderly in time so as to contact the doctor in time.
Old people in rural areas are sickly (when they are young, they exert great efforts, resulting in physical overdraft) and are prone to illness. And away from the hospital, with monitoring, you can better observe the physical condition of the elderly, so as to contact the doctor as soon as possible. Isn't it? Many old people in the countryside died of illness within a few days at home, and no one knows.
Third, leave evidence of swindlers or thieves.
Now there are many swindlers or thieves (many in the city) who specialize in door-to-door deception and door-to-door theft of the elderly. With monitoring, we can leave strong evidence and images of these people, which is more conducive to law enforcement officers to quickly detect cases.
