What to know about home security systems

How home security systems work

Home security systems use several innovative elements to protect your home from potential burglars and alert you in the event of someone trespassing onto your property. Most home security systems are fitted with motion sensors to detect movement, triggering an alarm and sending you a notification. 

Home security systems work with a control panel that allows you to arm and disarm the system depending on your needs. Newer models include voice-activated control panels and key fobs. You can set your home security system up to alert local authorities or an alarm monitoring company if there is a security breach.

Advantages of home security systems

When you have a home security system installed, you have extra peace of mind that your home is secure and protected. If you choose to opt for a professionally monitored home security system, your home will be monitored around the clock, even when you’re not there. 

There’s a home security system out there for everyone, whether you want security cameras or shock sensors. Most systems can be personalized with add-ons to allow you to tailor your security preferences.

Over 80% of burglars check for a home security system before trespassing onto someone’s property, with 60% deliberately avoiding homes with a security system. The best way to protect your home is to take the proactive step of installing a security system.

What to consider when buying a home security system

High-decibel siren/alarm

When most security alarm systems are triggered, they set off a high-decibel siren or alarm to deter your intruder from hanging around your property. It’ll alert you or your neighbors to a security breach. Depending on your system, you could have your alarm system connected to an alarm monitoring company or the local authorities.

Glass breakage detectors

If an intruder is going to come into your home, they’ll rarely take the front door. A glass breakage detector feature will allow your home security system to recognize the noise of glass being broken.

Control panel

The control panel is perhaps the most critical factor in your home security system. It’s at the heart of the system and the element you’ll be dealing with the most. With some of the latest security systems, you can add voice commands and key fobs for added practicality. You can personalize nearly every element of your control panel to meet the needs of your property.

How much can you expect to spend on a home security system?

You can expect to pay in the range of $100-$500 for your home security system. It all depends on what kind of model you choose. It’s worth noting that most security systems will require you to add other services like alarm monitoring and maintenance. 

Home security systems FAQ

Will my pet trigger my home security system?

A. The majority of home security systems are ‘pet-immune,’ meaning that the monitor sensors will recognize it’s your pet instead of an intruder. This feature works by taking into account the movement, speed and mass of the object to identify a pet. If you’ve got pets that roam freely around your property, you’ll want to double-check that your system is pet immune.

Can I use a home security system in a rental property?

A. Wireless home security systems are ideal for rental properties as they can be easily installed, set up and removed with ease. You don’t have to worry about making any alterations to your property or leaving the system behind when you move out.
