Unseen Protection, Uncompromised Security

Secure the perimeter of your home or business with the AJAX MotionProtect Curtain, a sophisticated wireless indoor motion detector finished in a sleek black. Designed to create an invisible curtain of protection, this device is your first line of defense against intrusion through windows, doors, and other entry points. Its narrow-beam technology ensures that you can move freely within your space while the perimeter remains under vigilant watch. If an intruder attempts to breach the secured area, the system will instantly trigger an alarm.

Proprietary Optical Technology for Pinpoint Accuracy

At the core of the MotionProtect Curtain lies an advanced optical system featuring two passive infrared (PIR) sensors and a multifaceted mirror. This innovative combination allows the detector to gather double the information about its monitored zone, ensuring a rapid and accurate response to human presence while minimizing false alarms. Whether an intruder is running or moving stealthily, this detector is engineered to react instantly.

Reliable, Long-Range Wireless Communication

The MotionProtect Curtain communicates with an Ajax hub over the proprietary Jeweller radio protocol, ensuring a secure and reliable connection at a distance of up to 1,700 meters in open space. This two-way, encrypted communication is protected against jamming and tampering, providing you with constant and dependable security. Enjoy peace of mind knowing your system is always connected and protected.

Effortless Installation and Pet-Friendly Design

Setting up your MotionProtect Curtain is remarkably simple. The detector connects to your security system through the Ajax mobile application by scanning a QR code, and it can be mounted in minutes using the included SmartBracket. For households with pets, the detector can be installed in an inverted position to intelligently ignore animals, ensuring that your furry friends won't trigger false alarms.

Good quality
Color: Black
Have used the frother 5 days in a row. It comes already charged. Fingers crossed no issues when I eventually have to charge it. I love everything about it. It’s worth a little bit of extra money as you can control the blending power from slow to fast. Easily held with both hands to coordinate. Today for a change I elected to just add a touch of bourbon caramel syrup to my oat milk -an excellent choice! They give you two attachments which is helpful. I’m not hard on my kitchen appliances but it’s good to know I have an immediate back up if needed. I rinse frother attachment out immediately in a cup of warm water and air dry on a towel. At this point, I highly recommend. My next adventure in the kitchen will be Matcha tea. I will use the bamboo whisk for the actual tea. If I decide to add oat milk to the top,(such as for a cold latte) I will use this frother.

Higher quality then I expect, very satisfied
Color: Gray
High quality overall, very high powered. It looks really fancy and elegant. The adjustable speed knob on the top is really great. The stand looks really nice but isn't the best design because it is easy to knock over when you take it out, that's my only issue with it.

Mixes my protein shake powder
Color: Blue
My husband and I both drink protein shakes daily. We have vortex mixers that work great, but they are plastic and getting old, and really needed to be replaced. In an effort to reduce microplastics in our lives, I am trying to use less plastic mixing cups. I couldn't find anything small enough (other than regular blenders) with glass and metal parts that would work well for us. During my search on here, several frothers showed up. This one caught my eye because of the amount of sales, quick delivery, and of course, decent pricing. Some of the reviews had me a little skeptical, and time will tell regarding the longevity, but so far I am pleased. My protein powders are on the heavy side, but this little frother really gets the job done. Instead of having to use separate mixing cups (saving me on dishwashing), I just use my morning coffee cup (it's big enough) to mix my protein shake in. My husband just uses a regular glass. Neither of us can believe the power this little thing has. We are getting smooth shakes! Here is what I really like about it: It is powerful and mixes well; the frother is metal and not plastic; it cleans extremely easy; after making several shakes the battery has not died; can be used in glasses, coffee cups, even disposable cups (when we buy donut shop coffee); and I love the little stand which takes up barely any counter space. Less plastic, less clean-up, dependable (so far), and small, making it convenient even for travel. I'm really glad I got this, and hope it will last. One last thing, do not turn it on while cleaning under running water. (Yes, you can laugh.)

Powerful frother with a long rechargeable battery life
Color: Black
After purchasing three of the battery operated frothers. I finally found this amazing frother. It is very powerful so you do have to be careful not to slosh liquid out of your cup when you’re using it. But I have found it helps if you rotate the frother in a stirring motion while you are using it. That really helps keep the liquid from overflowing out of the cup. It has a sleek design and is rechargeable and the charge less about two weeks.I love this one so much. I take it with me when I travel. I actually left my original one at my mother’s house the last time I visited her and have ordered another one for my house. Highly recommend.

Great Power and Creamy Foam
Color: White
This frother is amazing and has really good power. It creates creamy, smooth foam in seconds and works perfectly for iced lattes, cappuccinos, and matcha. I love that it’s rechargeable and lightweight, but still feels strong and high quality. As someone who loves coffee, this has become one of my favorite tools for making café-style drinks at home. Easy to use, easy to clean, and looks beautiful on my coffee station.
