Our top pick for the best home security system, SimpliSafe is both easy to install and easy to use—we also like this option for its overall affordability and style. This Shield kit, a Best Buy exclusive, includes a base station, keypad, two motion sensors, key fob, and six entry sensors. Simplisafe supports Amazon Alexa, Google Assistant, and August Smart Locks (but not Apple HomeKit), though its “smart” integration is limited. Typically selling for more than $250 for this 11-piece kit, this deal offers another great drop to $160 if the components work for your home setup. Like all security systems, expect additional monthly costs for active monitoring.
