🚪 Stay Alert with Every Entry - Ever had that moment when you're deep in a Netflix binge and someone sneaks in? The SanJie Wireless Door Sensor Chime has your back, pinging you the second a door or window cracks open. Perfect for keeping tabs on your space, whether it's for security, curious kids, or making sure grandma doesn't wander off.
🔊 Customizable Alerts - With 26 chimes to pick from and volume control that goes from 'whisper' to 'can't ignore', you'll know what's up without jumping out of your skin. (Because who needs that kind of stress?)
🏠 Easy Installation - Stick it, screw it, and you're done. No tech degree required. Plus, it's ready to go right out of the box—because waiting is overrated.
📶 Long-Range Coverage - 500 feet means it'll reach you even if you're hiding in the backyard pretending to garden. (We won't judge.)
💡 LED Indicators & Memory Function - Lights to catch your eye and a memory that sticks, even when the power takes a nap. Handy, right?
🔄 Expandable System - Got more doors than a hotel? Add as many sensors as you need, each with its own tune, so you'll know exactly where the action's at. No guessing games here.
