Buyers Guide to Home Security Systems

Security systems are an important addition to any home. But how do you know which choices are right for your needs? Here’s a quick breakdown of what you need to know before choosing your home security systems Nashville.

Types of Home Security Systems

Security systems need to send out signals. These signals either go from one unit to another, to the security company itself or maybe even right to your phone. The way these signals are transferred has changed over time. Now, you have choices as to how this process happens.

But what’s the difference?

Landline Security Systems

These systems are hardwired between the sensors and the main unit. The whole system is then wired into the phone line for the house. These systems are very reliable although prone to sabotage. Since everything is hard-wired, it’s susceptible to a simple wire snip.

Landline systems are the cheapest form of security. As previously stated, this doesn’t mean the system is unreliable. Hard-wiring the system means signal transference is very reliable. However, landlines are quickly becoming less popular as more households move toward cellular phones. This advancement in technology also means many of these systems are becoming obsolete.

Wireless Security Systems

Wireless systems are pretty much just what the name says: Sensors and detectors connect to the control panel without the help of wires. They make use of GSM or CDMA networks (these are networks generally used by cell phones) to connect with the monitoring station.

These systems are more expensive than their hard-wired counterparts. They remove the major vulnerability in landline systems since there are no wires to cut. The signal is quicker than that of landline systems as well. However, the signal is dependent on the strength and stability of the network. Battery backups are always installed to make sure power loss doesn’t knock out your system.

Internet Security Systems

This is another means of connecting a wireless system. Internet systems have all of the same advantages of wireless systems connected by cell phone networks. They are quick and they are not susceptible to simply having the wires disconnected. However, if the internet source loses connectivity, so does the security system. Although, measures can be taken to continue coverage through an outage.


Installation is the first step after figuring out which type of system will work best for you. But the options aren’t done. You can now choose between installing the system yourself or enlisting the help of a professional. Each has its advantages and disadvantages, so it’s important to learn which will better suit your needs.

Professional Installation

A security professional will come to your house and install all the necessary components. This is the best way to ensure everything is done correctly. A professional has the knowledge and expertise needed to properly install everything the first time. However, should there be a problem with the equipment, they will be available for troubleshooting and routine maintenance.

DIY Installation

Many security features on the market right now can be installed on your own. This saves the homeowner money on the front end. However, this opens up vulnerabilities in the possibility something is installed incorrectly. It could also mean there are holes in your security coverage. You can never be completely sure everything is working in the manner it should without the help of a professional. But, if only a small level of security is needed, DIY installation is worth looking into.


There are many options to customize your system to your particular needs. Perimeter alerts are just the beginning of home security. Here are a few more options to ensure your property remains safe.

Smart Security

These systems compound upon the wireless capabilities of your security system. Alerts can be received through applications on your phone. Automation can turn your lights on and off at scheduled times to make it seem like you’re home when you’re not. Automatic door locks can lock your doors even when you forget. Incorporating new technology in your security system helps keep your home safe in ways that weren’t possible until now.


Security cameras are some of the best tools you can have when something out of the ordinary is happening. The technological advancements are able to record clear images. This can be used to know when a package arrives at your front door. It can also be used as evidence if something goes wrong. These cameras are often water-resistant and capable of recording images in the dark of night.


These detectors alert you as soon as something out of the ordinary occurs. They are great tools to keep you and the ones you love safe by acting as another set of eyes. You can’t always be there to make sure your home stays safe. That’s why these items are essential in ensuring crime and danger don’t make it into your house. These items include:

  • Smoke Detector

  • Glass Break Detector,

  • Motion Detector

  • Door/Window Contact
