GREENCYCLE Motion Doorbell, Door Chime for Business Entry, Store Welcome Buzzer Monitor, Motion Detect Alarm, Caregiver Reminder for Elderly, Visitor Bell - 1 Receiver 2 Sensors

This motion sensor alarm 100% solved an issue I had with folks walking into an unauthorized area at work. Installed and set up in under 10 minutes, no issues. Some users say that the 'Alerts' (chime, voice announcement, alarm siren sounds, etc.) are too loud, and can't be set to a comfortable volume. (Maybe the manufacturer has fixed this in an update), but I found the (4, or 5) volume levels on the main unit to include a volume low-enough to be perfect in a quiet office environment. Plus, you can set the main (larger) unit to *only* flash its (incredibly bright) LED without making any sound whatsoever, if desired. Note that the LEDs on both the Motion Detector head, and the Main Unit on the one I received are not RED — but a pleasant, bright blue color. Each component has a 'Mini USB' port which I'm assuming gives you the option for external power, but for now I'm just using the 'AA' Battery option in each device and getting really great results. Both the Motion Detector, and the main Receiver Unit have their own power switch so you can turn them off when not needed. Very happy with this unit.

I purchased this to alert me when my cats wanted back inside. It works great! I initially wanted to install the sensor inside but discovered it does not sense motion through glass. A small bit of two sided sticky velcro tape solved this. The alert is loud and I can hear it anywhere in my house. It does take a lot of batteries (6) but it's well worth it.

Product works and we’ve found an angle where it works great in the shop. It just takes a while to find the right place to put it because the sensor is sensitive and will go off randomly if not placed correctly.

I recently added the Greencycle Motion Sensor Doorbell to my store, and I'm thoroughly impressed. Its sensitivity in detecting motion ensures that every entry is acknowledged, making it an invaluable tool for enhancing customer service. The flexibility it offers, serving not just as a business tool but also as a caregiver reminder, showcases its versatility. This product has seamlessly integrated into our daily operations, providing both security and a warm welcome to every visitor.

Bought this for my store works great even has different languages

We really like the product. I got one for work because I can’t see when someone enters the office. And my cousin in rehabilitation facility because he would wake up to the nurse or aide at his bedside. Now he’ll awake before they get to him. And other patients just walk in his room. It has a remote control so he can turn it off and on whenever he likes. It is worth every penny.

I love this thing, and I have 3 of them. At first, i simply used 1 to alert me when someone came through front door at work. Then, one night my work van got burglarized at a jobsite, and i had an idea -- put one in my van while it's unattended at work and home.At home, work or remote jobsite i strategically place motion detector in van, and keep alarm near me. Test range, but so far i haven't exceeded it.One night, alarm sounded around 3:30AM. I ran off 2 burglars that had just barely got my van's door open. I know they heard alarm inside building because it is incredibly loud and piercing, and they were already scattering when i arrive after 30 seconds. They might have stolen my van or tools without this thing. My car alarm didn't notify we til 3 minutes later! And it's just a notification on my phone. No good.I have burglar alarm that texts me, beeps the clicker, etc., but you can miss those if asleep or working in noisey place. NO MISSING THIS ALARM!! It is loud and piercing. Now, it has lots of settings for different tones, songs, greetings and volume. It even has a white light that stays on 2 minutes if you need temporary illumination in a dark hall or tiolet. And it has silent alarm if you just want lights to flash. You can have more than one in same area and they will work independently. Instructions say i can pair more than one motion detector to single alarm, but i haven't tried it.The possibilities are unlimited what you can do with this, AND ITS SO QUICK & INEXPENSIVE! Don't want kids in garage -- hello. On a jobsite: put 1 in van and one in toolbox while you go into ceiling -- If any dirtbag opens YOUR van or tool box to snoop, SURPRISE. Maybe you have a shed out back and neighbor borrows tools? Set this up in 2 minutes and next time anyone enters that shed, you know it (if you are home to hear alarm).Of course, true alarm systems can call, text and email you, but this is a quick and easy problem solver if you are within range.You can even prank your friends & family, or scare HALLOWEEN munchkins by placing them in fun places. Put one behind shower curtain or inside kitchen cabinet and scare the wife. Sounds like a YouTube video waiting to happen. ENJOY.

I got this so I could tell when my cat was outside. It works great. The chine is a little annoying and there is no reason to play the entire song

Works well, good volume control. No fuss to set up with the sensor adjustment being excellent. Like the idea of being able to wire it via USB cable so I don't have to worry about batteries.

doorbell works well

Works great, showed up on time
