Streetwise Door Stop Alarm – 120 dB Portable Wedge

Add instant protection to any room—no tools, no setup. Slide the Streetwise Door Stop Alarm behind an inward-opening door and the wedge design both blocks the door and triggers a piercing 120 dB siren the moment pressure is applied. Adjustable High/Medium/Low sensitivity helps reduce false alarms whether you’re at home, in a dorm, or traveling. A simple ON/OFF switch, compact footprint (≈5.5" × 2" × 1.5"), and 1-year warranty make this a reliable, go-anywhere security upgrade. Requires one 9-volt battery.
