Success! - I recently started using an indoor doorbell-style motion sensor as a deterrent in my multi-cat household, and it has been a game changer. With several cats, occasional marking and unwanted behavior can become a challenge. This simple device has worked surprisingly well to stop the problem before it starts. The sensor is easy to set up and sensitive enough to detect when a cat approaches the problem area. When triggered, it makes a noise that can be adjusted in volume. The sound is not harmful or harsh, but it’s unexpected enough to startle the cats just enough to make them back away. I’ve noticed they quickly associate the area with the sound and choose not to go near it anymore. What I like most is the adjustability. In a home with multiple cats, I needed something effective but not overly stressful for them. Having the ability to fine-tune the noise means I can use the lowest level that still does the job, which keeps the atmosphere calmer. Overall, this has been a safe, effective, and humane solution for deterring marking indoors. I highly recommend it for anyone with multiple cats who is looking for a low-stress way to prevent unwanted behaviors. Review: GREAT Stand-Alone Motion Sensor Alarm - Perfect for what I was looking for: A SMALL, STAND-ALONE, NON-WIFI REQUIRED, LOCAL Alarm that is super easy to set up. Slap 3x AAA batteries in it, turn volume down, select tone and re-adjust volume, turn it on and point it where you need it. It is "locally" loud, but not Super Loud; it would definitely wake you up if you're within an unimpeded 100'. The hinge allows approx 240 degree range in approx 20 degree increments, all the way to approx 30 degrees below parallel in either direction. Setting this on a stair run pointing down the stairs is stable and works great to cover the stairs too. Range is short- 10-15'. Smallest configured Size: approx: 2.5x3x3" Great little motion sensor alarm for anywhere you need. Great to enhance security at Hotels, BnB's, even camping! ## Features - ♫ Brief Introduction: Combined with motion detection, 90db alert and flashing red light, 2-6M detection range in open area, this standalone, all-in-one chime alarm plays an important role in informing you of intruder or visitor.
