Technically speaking, a burglar alarm consists of just the skeleton sensors necessary to detect an intrusion door, window, and motion and notify the homeowner with an audible noise. An alarm system extends this to also include fire and smoke detectors. Taking it a bit further, a home security system also can include monitoring by a central station, home security cameras, remote control via your smartphone, and home automation options such as automated lighting and door locks. With all the tech options today, you probably want to choose this more comprehensive security system to best meet your needs. For most home alarm options, yes. Some burglar alarms are “do it yourself”, or self installed. It sounds scarier than it is. In fact, it can be very easy since this usually involves simply attaching sensors to your doors and windows using sticky peel and stick adhesive tape which is also provided. Most of the national security system companies have professional install options available if you prefer, but they can add to the cost and could involve drilling holes in your walls. So with wireless technology, more companies including Frontpoint, SimpliSafe, and Link Interactive are relying on a “Do It Yourself” model. DIY allows you to save money on installation and moving costs down the road.
