Security solution for home

[richbanks]

Hi everyone,
Hope everyone's doing okay.
I have got a problem that is bugging me. I work in a private firm and I live with my grandma. Sometimes I have to work late and we have a nanny here to help my grandma. My grandma is old but healthy. So the nanny would help her do all the works and look after her when I am not at home. But now I am thinking of installing a home security system from Toronto so that I would get alerts on my phone in case of any emergency.
What are your suggestions on this? Any insight on this would be great.
Thanks in advance!
