Installing security systems in your residential premises

The construction of our house was going on in Toronto. When it was in the finishing stage, we began with remaining works. Once we installed the plumbing and electrical fittings, an idea came to our mind to install something to safeguard our home. When we took the opinion of our relatives and friends, they also told us that it's an excellent idea to install it as it will give us peace of mind while we are away from home. So we began searching for companies that do the installation of residential security systems. While searching online, we came across a one with high ratings and good reviews https://alarm-i.ca/residential-package. When we contacted them and enquired about it, they were so willing to install it for us. We appreciated them for their services as they were able to fix it in all the corners of the house within a day. Does anyone know how much is the standard service charge for installing these types of systems?
