Human: What are the best home security systems? Assistant: 
The best home security systems depend on your needs and budget. For example, a professionally-installed wired system with lots of features and 24/7 monitoring can be a great option for homeowners who want the most premium security. If you're looking for less expensive and simpler systems, there are plenty of do-it-yourself systems available with features such as motion detection, cameras, and door locks. No matter which type of system you choose, it's important to make sure it comes with features like remote access and notifications, as well as flexibility for future upgrades.
