Loud and Clear: High-Decibel Alarm with Outdoor Siren
Powerful Sound That Demands Attention
At the heart of the KERUI Home Security System is its loud siren, capable of reaching up to 110 decibels. That’s louder than a motorcycle engine or car horn and enough to alert neighbors and frighten away intruders immediately. It’s a reliable deterrent that doesn’t rely on subtlety—once it’s triggered, the entire block will hear it.
Weatherproof Design for Outdoor Placement
What sets this system apart from other budget home security kits is its weather-resistant siren, allowing you to place it outside the home where it’s most effective. The siren is built to withstand rain, snow, wind, and UV exposure—ensuring 24/7 readiness in all conditions.
This is especially important for properties with detached garages, garden sheds, or accessible outdoor entry points. Your perimeter is protected rain or shine.
Door and Window Sensors: First Line of Defense
Wireless and Easy to Install
The system comes with wireless magnetic contact sensors for doors and windows, which are often the first entry points targeted during a break-in. Each sensor is battery-powered and attaches using strong adhesive or included screws—making them suitable for both permanent homes and rental spaces.
Real-Time Intrusion Detection
Once armed, the system monitors the contact points. If a door or window is opened unexpectedly, the sensor triggers the siren within milliseconds. You can also pair multiple sensors to cover multiple zones, such as front and back entrances, bedroom windows, or basement doors.

Customizable and Expandable Setup
Supports Multiple Accessories
The KERUI Home Security System is more than just a one-size-fits-all solution. It can be expanded to support up to 99 wireless zones, including:
- Motion sensors (PIR)
- Smoke detectors
- Remote control keyfobs
- Additional door/window sensors
- Vibration or glass break sensors
This flexibility allows you to create a security setup that grows with your property or changing needs. Whether you start with a basic 3-piece system or build a full home-wide perimeter, KERUI makes expansion simple and budget-friendly.
Remote Controls and Easy Arm/Disarm
Wireless Keyfobs for Convenience
The system includes remote control keyfobs that allow you to arm or disarm the system at the touch of a button. You can also switch between “Home,” “Away,” and “Emergency” modes depending on whether you’re inside the house or heading out.
These remotes are especially useful for kids, elderly family members, or anyone who doesn’t want to use a smartphone or keypad interface.

Indoor and Outdoor Coverage in One Kit
Full Spectrum Monitoring
Most DIY home alarms are either indoor-only or require complex setup for outdoor functionality. With KERUI, you get indoor and outdoor coverage right out of the box. Install sensors inside to monitor entries and place the siren outside to startle intruders before they even open the door.
This dual-layer approach ensures you don’t just detect intrusions—you actively prevent them.
No Wi-Fi? No Problem
Standalone Security System
The KERUI Home Security System does not require Wi-Fi or a cellular connection to function. This is a huge advantage for cabins, garages, storage units, or homes with unreliable internet. The entire system operates independently using radio frequency signals between the sensors and the siren.
No router pairing, no app configuration, and no cloud dependency—just solid, old-school security with modern reliability.

No Monthly Fees or Subscriptions
One-Time Purchase, Lifetime Protection
Unlike many modern smart alarm systems, KERUI has no hidden costs. You won’t need to pay monthly fees, sign a contract, or rely on cloud servers to get the full functionality.
This makes it perfect for users who value privacy and prefer to keep control local rather than handing over their home data to third-party platforms.
Use Cases: Who Is This System For?
Homeowners
Protect doors, windows, sheds, and even driveways with a customizable alarm solution. It’s easy to expand the system with additional sensors over time.
Renters
No drilling is needed for installation, and the system can be taken with you when you move. Wireless sensors are ideal for apartments and condos.
Small Business Owners
Install the outdoor siren above your storefront or warehouse entrance, and add sensors to key doors or display cases. Deter after-hours break-ins without investing in commercial security contracts.
Vacation Homes or Cabins
Since it doesn’t require Wi-Fi or cellular, this system is ideal for remote locations with limited connectivity. Keep your getaway secure all year long.
