YBJ YB-108-4GUS-D Alarm System for Home Security: No monthly fee with free app control
This YBJ alarm system is designed for homeowners who want reliable protection without monthly fees. Perfect for families who need to secure their home while at work or traveling, it gives you control from your smartphone.
Unlike basic security systems, this kit offers dual-network reliability. The 4G backup keeps you connected even during power outages, so you never miss an alert. The motion detectors can sense movement from across a room, and the app sends notifications faster than you can check your phone.
Setup takes minutes with no wiring. You can expand the system with up to 200 sensors as your needs grow. Use voice commands with Alexa or Google Assistant to arm the system hands-free. The loud alarm and instant alerts provide real security, not just features.
Features
- Easy to install with no wiring required
- Supports WIFI and 4G dual network
