Best Budget: Thustar Home Alarm System
Some of the more high-tech DIY security systems can cost several hundred dollars, and if you’re just looking to test some of the technology, you might not want to make that large commitment.

There are a number of ways you can arm and disarm the system, including with a pass code, with a Nest tag, or via the Nest app. The tags are great for families in detail, as they save children from having to remember a pass code, and you can sync up to 10 of them with your system. The Nest Detect Sensors are designed to sense motion up to 15 feet away, so you can point them at doors or windows, and if the system isn’t disabled, they’ll trigger the alarm.
Reviewers love that this system is both comprehensive and easy to use. Plus, you can set it up with other Nest devices, such as the brand’s popular indoor and outdoor security cameras.

Best Landline-Compatible: Fortress Security Store Wireless Home Security Alarm System
Most wireless security systems connect to your smartphone, but if you don’t want to rely on your phone, a product like the Fortress Security Store Wireless Home Security Alarm System, which can be set up with a landline. This security kit comes with the main panel, two motion sensors, five door/window contact sensors, two key tags, a panic button, two remote fobs, and a plug-in siren.

The system also includes multiple arming modes, such as “Away Alarmed” and “Home Alarmed,” so you won’t accidentally set off the motion detectors when you’re in the house.
What to Look for in a Home Security System
Some home security systems add extra peace of mind by offering an additional monitoring service. The upside is that if there is an intruder, the service can intervene quickly and call the police if necessary. On the downside, you can expect to pay an additional monthly fee for monitoring and it often (but not always) means signing a contract for a year or more. Other home security systems skip professional monitoring in favor of features such as smartphone alerts and self-activated sirens.
Smart Home Compatibility
Many of today’s home security systems are built with tech integrations that allow the system to work with popular smart home platforms such as Google Home, Nest, and Amazon Alexa. Taking advantage of smart home compatible security systems can boost your confidence that your home is safe and secure and allow you to automate certain functions of your home’s security protocol.
With a video-enabled security system you will get a live look at your home anytime and from anywhere, or receive real-time alerts when your home security system detects an unusual event. Some cameras will continuously record surveillance footage and upload it to a cloud server, while others save battery life and storage space by only recording motion-triggered events.
