ZX SN11 WiFi Alarm Siren: Loud 110db alarm sound
This alarm system is for the busy homeowner who wants simple, reliable security without a monthly fee. While many focus on deterring intruders, it gives you peace of mind by letting you check on your home from anywhere, like verifying a package delivery or ensuring the kids turned off the alarm after school.
The 110db siren is loud enough to startle a potential intruder, but the real value is in the app. You get instant alerts on your phone when a sensor triggers, so you can act fast. The system supports up to 50 wireless sensors, so you can easily expand coverage to doors, windows, and motion areas. It works with Alexa for voice commands, making it a seamless part of your smart home setup.
