Alarm Systems

6938 listings

Alarm kits run from simple DIY door/window setups to expandable panels with keypads, sirens and sensors. Decide between self-monitored (alerts to your phone, no monthly fee) and professionally monitored, and check whether the system is wired or wireless and how many zones it supports. Confirm the kit includes everything pictured and that any pre-owned panel isn't locked to a former owner's account.
