Enhanced Signal Antenna: After market research, we found that the signal antenna of many products on the market is built inside the product, and the antenna is too small to penetrate obstacles, resulting in limited transmission distance. Our external antenna, anti-interference ability is stronger, the transmission distance is farther, the signal is more stable and not easy to fall off.
Flood probes with wires: Do you have extreme corners or narrow crevices where there is no way to place a detector? In order to make the detector more adaptable to all kinds of extreme and narrow environments, we use wired probe wires instead of the cost-saving method of making detection probes directly on the detector.
Advanced Integrated Functions: Compared to other water alarm kit, our host can connect up to 30 wireless sensors with a frequency of 433MHz. If you need to add more devices, such as motion sensors/door sensors/ siren, etc., you can satisfy more of your usage requirements.
Customize your needs: In addition to adding more different types of devices, our APP also has more customizable features: including setting different alarm ringtones, alarm duration, delayed alarms, alarm volume, and other different features to choose from!
Ready to Use: Download the app, connect the devices to the app via the 2.4 GHz Wi-Fi network (incompatible with 5 GHz). When a water leak is detected, the main unit alarm goes off and pushes the information to your cell phone so you can receive the alert quickly even if you are not at home; you can also share the device with your family so they can also check the status of the device anytime, anywhere.
