My mother is the one who takes care of my kids when I and my wife goes for the job. But recently she had undergone a major heart surgery and is advised by the doctor to take rest for few months. Hence I have appointed a nanny to take care of my kids. But the nanny stays at home only up to evening after which my mother and kids are alone. I and my wife will reach only the late night after the work. At this point of time, I am little scared to leave my kids alone at home as my mother is not well. So I thought of installing a security system with the help of a residential security company. Can someone suggest me the recent technologies involved in security systems? Which are the security companies that provide such services in case of emergency? Do share your suggestions as it would be of great use.
