SECRUI Wireless Door Open Sensor Chime - Adjustable Volume, 400ft Range, 52 Chimes (M508+D7)
Ever wanted a little heads-up when someone opens your door or window? The SECRUI Wireless Door Open Sensor Chime has got your back, blending security with a touch of personal flair. Choose from 52 chime options—because why settle for boring? Plus, crank it up or tone it down with adjustable volume (0-110 dB), because sometimes you need a whisper, and other times, a shout.
Here’s the lowdown on what makes this gadget a must-have:
- Volume control? Check. Five levels mean you’re the boss of how loud it gets.
- With 52 chimes, including the classic "Ding Dong," you’re spoilt for choice. (Pro tip: Pick a tune that won’t drive you nuts by the third day.)
- It remembers your last pick—melody and volume—so no resetting every time.
- Boasts a 400ft wireless range in open spaces. That’s like, really far.
- Installation’s a breeze: plug in the receiver, stick or screw the sensor, and you’re golden.
- LED indicators give you a visual nudge, because why not?
Ideal for homes, offices, stores, and pretty much anywhere you don’t want surprises. Just a heads-up: wooden doors and mailboxes? Not this gadget’s jam.
