Available Options
This 7-piece wireless smart alarm system is designed for renters or homeowners in a 1-2 bedroom space who want reliable security without long-term contracts. It's perfect for monitoring entry points and common areas, giving you control over your home's safety from anywhere.
Think of it not just as a home security system, but as a flexible tool that grows with your needs. You can start with the included sensors and easily add more later, like extra door sensors for a new room or motion detectors for a garage. The dual-network support keeps it online even during Wi-Fi outages, so you get instant app alerts without delays—often before you'd even notice something's off.
Use the mobile app to arm or disarm the system remotely, and integrate with Alexa for hands-free voice commands. With no subscriptions or monthly fees, it offers peace of mind without the ongoing cost, making security accessible and adaptable to your lifestyle.
