Our neighborhood is well known for burglary. The police have been catching burglars for many years, but still incidents of housebreaking and robbery continue. Every house in the neighborhood has their homes installed with security alarms because of which there is a decrease in the episodes of theft. We also installed security alarms in the house long back, I think, it is time to upgrade it. But we had built the house with the wires integrated into the walls. Is that a problem? Is it possible to change the alarm systems to wireless? I have heard about alarm systems which instantly messages to the owner and the concerned officials in case of a breach. Even one of my neighbor has installed such a system. He did it from a company specialized in alarm system services in Hamilton. He was installing that for the first time. So I was wondering whether the old system is any roadblock in the installation of the new system. I don't have any backup generators in my home. Does the wireless alarm system consume a lot of power? Please do provide me with suggestions. Thank you.
