Let me start by saying this CPVAN alarm system is a game-changer for home security. The 120-decibel siren is no joke—it's loud enough to make intruders think twice and alert you immediately via smartphone notifications. I tested it in my garage, and even with doors closed, the sound was unmistakable.

The setup was surprisingly easy. The SmartLife/Tuya app guided me through connecting all 9 pieces (1 motion sensor, 6 door/window sensors, and 2 remotes) in under 15 minutes. The adhesive strips on the sensors held firmly to my windows and doors—no drilling required!

I particularly love the three modes: Away (full protection), Home (motion sensors disabled), and Disarm. The remote controls are handy when I'm too lazy to use the app. Pro tip: The 'welcome chime' feature in Disarm mode is perfect for knowing when family members arrive without scaring them with the full alarm.

Now for the cons: Battery life is indeed short—about a week with frequent use. I solved this by using rechargeable AAs. Also, while the system works without WiFi (using backup batteries), you lose app notifications during outages.

Compared to expensive monitored systems, this DIY kit delivers excellent value at no monthly fees. It's given me peace of mind knowing my tools and shed are protected day and night.
