Protecting your home isn’t a simple task. And the plethora of options available for the consumer doesn’t make it any easier.
From comprehensive 24/7 security systems to simple, self-managed and self-monitored options, there are a variety of system types on the market today.
With different devices, companies, services, and products, the question is:
How many types of security system are there?
While there are many security system types, we believe you can break things down into 10 main categories. We are arguing that there are ten security system types prevalent today.
This guide goes into brief detail about the 10 types of home security systems, helping you understand their basic features and how they contribute to home safety.
Alarm New England has been an expert in the region for 50+ years, so if you have any questions our local and family-owned security company is happy to get things started for you.
So, without further ado, let’s get into the home security system list:
1. Burglar Alarm System With 24/7 Monitoring

Monitored burglar alarms are connected to a professional monitoring center where a trained operator will handle any and all signals. When triggered, the operator will contact the homeowner or any designated contacts on the account. If it’s an emergency, or if there is no response, the operator will then quickly dispatch emergency responders to deal with the situation. These systems are the safest because they are monitored by a live person day and night. They leave no room for error, and you can feel good having your home under watchful protection with 24/7 monitoring. A professionally monitored burglar alarm system eliminates stress for the homeowner and allows for a fast response in any emergency.
2. Unmonitored Burglar Alarm System

Unmonitored burglar alarms sound a loud siren or alarm when triggered. It’s simply noise, there is no live person on the other end monitoring the system. An unmonitored system can be effective, but it’s not a sure fire response in any scenario. These systems rely on the noise to deter intruders and alert neighbors. Because of this, there are no monthly monitoring costs, but this can lead to major regrets in a real emergency situation, especially if you are far away from home.
3. Home Security Cameras

Cameras are the eyes and ears of your property. If you want visibility into your living space when you are not there, cameras are the simple answer. Security cameras record video footage, allowing homeowners to monitor their property in real time or review past events if the system has the memory needed to store footage. Many smart cameras systems store video in the cloud that’s easily reviewable from a mobile device. Modern home camera systems might offer features like motion detection, night vision, video analytics, and smartphone integration.
4. Smart Locks

Smart locks let users lock and unlock doors remotely using a smartphone or a keypad. They enhance convenience and allow homeowners to control access without physical keys. Smart locks are slowly becoming the new standard. Soon, we’ll no longer need to remember our keys, and the security threat of lost keys will become a thing of the past.
5. Smart Thermostats

Smart thermostats manage home temperature settings even when the user is away from the property. Lower your heat when you are not home, and then walk into a heated house when you get home from work by setting the heat remotely. Forgot to turn off the air conditioner? Don’t fret, because you can simply switch it off via your phone with a smart thermostat. These home temperature systems aren’t just convenient, they improve energy efficiency and help you save on your bill.
6. Home Doorbell Cameras

Doorbell cameras combine video recording and two-way audio. They allow homeowners to see and speak with visitors from a smartphone app, allowing for the utmost in security and convenience, even when away from home. They are even convenient when you are at home. See and speak to whoever is at the door without even needing to leave your chair!
7. Home Fire Alarm Systems

Fire alarm systems detect smoke or heat and alert occupants to evacuate. Some systems connect to monitoring services for immediate emergency response. Most homes have a smoke detector requirement, so you are probably familiar with a system like this.
8. Home Carbon Monoxide Alarms

Carbon monoxide alarms detect the presence of carbon monoxide gas, which is colorless, odorless, and dangerous. They sound an alert to protect occupants from poisoning.
9. Flood Sensors

Flood sensors detect water leaks or rising water levels. This system type helps homeowners prevent extensive water damage by alerting them to issues early. Water damage is costly and difficult to fix, so these types of flood sensing systems can be very important when called upon.
10. Medical Security Pendants

Medical pendants are wearable devices that allow users to call for help in emergencies. They are ideal for elderly individuals or those with medical conditions that might be a hindrance to calling for help in an emergency situation. Medical pendants take some of the worry away from leaving an elderly or disabled loved one unsupervised for periods of time. If an emergency arises, they can simply press the button to access assistance quickly. These systems are also often called “personal alarms” or “panic buttons.”
