A home security system generally functions by installing different types of sensors, including motion sensors around different areas of your house. The control panel will arm or disarm the system and will sound an alarm if a security spot is triggered. Most reputable home security companies offer 24/7 around-the-clock monitoring and in the event that an alarm is triggered, they will first contact you and then the proper authorities.

There are a range of different types of home security systems that are worth looking into. The main difference between them is the monitoring, whether they are monitored or unmonitored. Unmonitored security systems often cost less and give you the ability to install and monitor them yourself, making them a cheaper option. Monitored systems are perhaps the more convenient option although more costly. They are monitored by a professional home security company who keeps an eye on your home 24/7 and will automatically provide emergency services in the case of an incident. Therefore, you can leave your home and head out for the day with peace of mind that your belongings are safe and secure.

When deciding which home security system is the one for you, you should determine if you'd like a professional to install your system or if you prefer to go the DIY route. With a professionally installed system, you don't have to worry about installing it incorrectly because a trained security professional will come to your house, install it, and usually will show you how to use the system. They tend to be higher quality and more reliable than DIY systems. However, professionally installed systems tend to cost more because most providers charge an installation fee plus it can take more time as you will have to wait for a professional to come to your house when they have availability.DIY systems tend to be less expensive as you don't have to pay an installation fee; you can install it as soon as you get the system. You can also build your system gradually and add pieces as needed and they tend to be easier to move from one home to another. However, DIY systems are harder to install in large, multilevel homes and are harder to maintain as your provider might not have a professional to repair it.

Generally wireless home security systems are more advanced due to their flexibility and customization. They allow you to easily connect different devices to your home security system via Bluetooth or Wi-Fi. However, it has often been said that wired systems are more reliable as they are not dependent on internet or cellular connectivity.

The short answer, yes. In recent years there has been a significant increase in the number of burglaries taking place meaning that more and more people have started to look into purchasing home security systems. Although they can be pricey to install, in the long term, having a home security system can actually save you money by helping to reduce your homeowner's insurance. It is certainly safe to say that home security systems are the most effective way to deter intruders from entering your home.
