How Wireless Security Systems Work?

A wireless security system operates by networking the monitoring devices so that they transmit information back to the receiver, control panel or other receiving device. Depending on the devices that are included in your system, you may have to choose your placement carefully. The devices used in a wireless security system usually have a “range of effectiveness”, in which they are able to easily transmit information back to the receiver.

For example, your security system may have a wireless door sensor that activates when a door is opened. However, in order for the signal to be able to transmit from the door sensor to the monitoring device, it needs to be placed within a range radius. This allows the signal to be accurately received and converted by the monitoring device into an “alert” in the system. If the wireless door sensor is placed outside of this range, it may not be able to effectively transmit a signal back to the monitoring device.

Advantages of Wireless Security Systems

Wireless security systems are rapidly increasing in popularity, due to the many advantages they have over traditional wired security systems. Some of the advantages of wireless security systems are:

Easy Installation.

Since a wireless security system does not require the use of long extension wires, behind-wall wire installation, or other procedures, it is fairly easy to install. Even if you do not have any technical experience, it is still possible to install most wireless security systems without assistance. Many wired security systems need to be installed by trained experts, which may sometimes result in an additional installation fee.


With a wireless security system, you are not restricted to place the devices of your system within the range of their wires. This means that you have more freedom to place your devices in a way where they will be most effective in monitoring your home.


After installing a wireless security system, you have the ability to easily take that system with you when you move. With a wired security system, it can be very difficult to reinstall the system in a new home, especially if you need to pay the installation fee again. Wireless security systems are highly portable, and can be moved to a new residence with fairly little difficulty.

Disadvantages of Wireless Security Systems

Like with any electronic device, a wireless security system does come with a few disadvantages over wired security systems. Here are the most important disadvantages that you need to be familiar with.


Wireless security systems tend to be a bit more expensive (for the cost of the system components) than wired security systems. This is mainly because each device in your system needs to have the ability to transmit wireless signals back to the receiving device.


Due to the range of effectiveness of a wireless system’s signal, devices that are placed near the edge or outside of this range may not be able to easily transmit back to the receiving device. This can result in the wireless devices not being able to function properly to effectively monitor your home’s security.

Installing a Wireless Security System

Installing a wireless security system on your own is a fairly straightforward process, as long as you are familiar with your system and its devices. Here are some quick tips for proper wireless home security system installation.

Choose Your System.

Before beginning installation, it’s best if you first choose a system package that will fit the security needs of your home. Many home security companies have customizable wireless security packages, which can be modified to suit your preference.

Plan Your Placement.

With wireless security systems, placement of your devices is essential. Each device has a specific distance range, which designates how far it can be placed from the control panel or receiving device. It’s best to choose the placement of your receiving device based on its proximity to where you need to place your monitoring devices.

Use the Proper Tools.

If you purchase a wireless security package from a home security company, you may only need a minimal amount of tools to correctly install the system and devices. However, if you are designing your own wireless security system, you may need to make modifications, which will require the use of different tools.

Landline vs. Cell Monitoring

In past years, landline monitoring was the only option for a security system to monitor a home. Today, there are more options, which can be used with your wireless security system.

Landline Monitoring

Landline monitoring is the traditional method that some security systems use to monitor the security of your home. This method requires the system to be plugged in to a landline phone line, so that it can transmit an emergency signal to the monitoring company that is in charge of your system.

CellGuard® Monitoring

Since many people today use cell phones as a semi-exclusive form of voice communication, more people are choosing not to install a landline telephone in their home. However, many wireless security systems are now designed to use an internet connection to monitor a home. If an emergency is detected, the control panel or receiving device will send a signal through the internet connection in order to alert of an emergency.
