Seeking a new security system? This bundle from Costco includes the Base Station, Keypad, Motion Sensor, Panic Button, Keyfob, four Entry Sensors, an HD Security Camera, and three free months of 24/7 interactive monitoring. After the free trial, you can choose between a $15/month standard monitoring plan (24/7 monitoring and a cellular connection), continue the $25/month interactive monitoring plan (standard features plus phone app control, push and email alerts, and 30-day event footage), or choose “no monitoring.” We recommend at least the standard plan.
