Every home has a blind spot—the gate your two- or four-legged Houdini tests when you're at work, the sliding glass door that guests never latch properly, or the attic hatch that pops open on windy days. The Contact King Alert System targets that single access point with precision monitoring that transforms uncertainty into instant awareness. The 40-inch cable that provides flexible placement— whether monitoring your mailbox from inside, tracking a crawlspace entry, or knowing when the outdoor storage box gets opened. It's the one spot where you need to know even if you don't see Spot run. Combined with the Temperature and Humidity Sensor, you're not just monitoring access—you're maintaining environmental awareness too. Start with one critical location now, expand your system whenever you're ready. 3-PACK SET offers Peace of mind, three sensors at a time.
