Hi folks, I am the mother of 2 children. My elder child is a mentally retarded child. He is 15 years old. My younger kid is just 3 months. Unlike before I don't get enough time to take care of my elder child. Now he started to move out of the house opening the door. The main problem is that our house is situated in the city. Since it is a very busy road, the chance of getting accident is very high if we carelessly walk on the road. Last day he went out of the house and entered the road. Due to gods grace, our maid saw him and took him back. I think it's high time to nstall a home security system. I'm planning a security system with the doors having deadlock protection. Since I haven't installed a security system before, I am a novice in this field. Has anyone installed it sometime recently? What would be the installation charges? Please do share your views. Thanks in advance. Spam link removed by mod team.
