About Wireless Home Security Systems
There’s no doubt that all of the products on the market today make it easier than ever to protect your family and valuables. So how do these systems actually work? First, let’s take a look at the components involved in a wireless home security system.
- The hub or control panel: this is the main component of your wireless security system and functions as the brain of the operation. Professionally monitored cellular systems and some DIY security systems will have a traditional or touchscreen control panel. If you opt for a setup that combines security with a home automation system, you’ll have a hub which you control from a mobile app.
- Sensors: these include door and window sensors, and sometimes indoor/outdoor motion sensors to alert you when there’s unexpected activity inside your house.
- Cameras: a wireless security camera gives you the ability to see what’s going on in real time indoors and/or out, and also allows you to record and store video.
- Alarm or siren: this feature is one of the most important parts of a wireless security system in terms of scaring off intruders. It can also alert neighbors to a problem if you’re not at home.
You may also have yard signs, window stickers, and key chain sensors which allow you to arm and disarm your system. Of course, with a smart security system, you will also be able to connect devices like door locks, lights, and more.

Cellular Security Systems
You have a few options when it comes to taking advantage of cellular technology in security systems. Some companies provide exclusively cellular monitoring, without the need for a phone line. This includes:
- Vivint
- Frontpoint
- SimpliSafe (this company also offers a self-monitoring option)
You can also choose a hardwired or DIY wireless security system with cellular backup in case the phone line or the internet is cut or goes down:
- ADT – two top-tier packages include cellular backup
- Protect America – cellular monitoring is optional and costs more than traditional
- Iris by Lowe’s – self-installed smart security system with optional cellular backup
A few companies offer broadband monitoring as well, although experts generally recommend hardwired or cellular monitoring over broadband because they’re more reliable.
