Home Security: Choosing the right system
Depending on your needs you can go with a system that you monitor yourself, or pay a subscription fee to have your home surveilled 24/7 by professionals who will contact your local fire and police departments when alarms are triggered. Of course, the more coverage you have, the more you can expect to pay.
If you're not ready for a dedicated security system there are plenty of individual devices available that let you monitor your home from anywhere using your phone or tablet, including indoor and outdoor security cameras, video doorbells, and smart locks. A smart home security system connects to your home Wi-Fi network so you can monitor and control your security devices using your smartphone and an app. Entry-level systems typically include a couple of door and window sensors, a motion detector, and a hub that communicates with these devices using one or more wireless protocols such as Wi-Fi, Z-Wave, ZigBee, or a proprietary mesh network. You can add extra door, motion, and window sensors to provide coverage for your entire house and build a comprehensive system that includes door locks, garage door openers, indoor and outdoor surveillance cameras, lights, sirens, smoke/CO detectors, water sensors, and more.
