Ever wished your front door could give you a heads-up when someone's coming? Meet the Bistee Wireless Door Alarm Contact Sensor—your new best friend in home security. It's not just loud; it's got 58 chimes and 5 volume levels (from whisper-quiet 0 dB to wake-the-neighbors 110 dB), so whether you're throwing a party or just trying not to startle your cat, it's got you covered. And with a 600 FT range, it's like having eyes in the back of your head—even if you're upstairs binge-watching your favorite show.
Thinking bigger? The expansion system lets you turn your humble abode into Fort Knox by adding more sensors for every door and window. Setup? Easier than assembling flat-pack furniture—just plug in, stick on, and you're done. Plus, it remembers your preferences after a power outage, because who has time to reset things?
And because we're not monsters, it comes with lifetime customer service. Oh, and it's FCC, CE, and RoHS certified, which is basically the tech world's way of saying 'this thing won't let you down'.
