Advanced 3-in-1 Protection for Every Entry Point
Secure your home or business with the AJAX DoorProtect Plus Jeweller, a sophisticated wireless detector that offers three layers of security for any door or window. This device instantly detects opening, shock, and changes in tilt, providing comprehensive protection against intrusion. Its advanced sensors are designed to protect even windows left open for ventilation, as the built-in accelerometer will register vibrations, impacts from attempted force, or any change in vertical angle. Housed in a sleek black casing, it seamlessly blends with your interior while offering powerful, professional-grade security.
Key Features:
- Triple-Sensor Detection: Combines a high-end reed switch for opening detection with a sensitive accelerometer that registers shock, vibration, and tilt. The tilt sensor's activation threshold is adjustable from 5° to 25°.
- Jeweller Wireless Technology: Employs Ajax's proprietary Jeweller radio technology for secure, encrypted two-way communication with the hub at a distance of up to 1,200 meters in open space. It features frequency hopping to prevent jamming and ensure reliable alarm delivery.
- Adjustable Sensitivity: The shock sensor has three adjustable sensitivity levels, allowing you to fine-tune the detector to your specific environment and prevent false alarms.
- External Detector Input: Includes a terminal for connecting a third-party wired detector with a normally closed (NC) contact type, expanding your security system's capabilities.
- Long Battery Life: Operates for up to 5 years on the pre-installed CR123A battery, minimizing maintenance. The system will notify you well in advance when the battery needs replacing.
- Effortless Installation: Ready to work straight out of the box. The SmartBracket mount allows for quick, easy installation without disassembling the detector's body. Connecting to an Ajax hub is as simple as scanning a QR code with the app.
How It Works
The DoorProtect Plus consists of two parts: the detector and a magnet. The opening is detected by a British-made reed switch when the magnet moves away from the sensor. Simultaneously, the integrated accelerometer stands guard against forced entry attempts by detecting vibrations and impacts, or if an intruder tries to open a window that is tilted for ventilation. In case of any event, an alarm signal is sent to the Ajax hub in just 0.15 seconds.

Definitely a good surprise
Size: 12.5, Color: A Black
Absolutely the most comfortable shoes I have ever had. Extremely lightweight true fit. They are very breathable. They are not a running sneaker.
They seem to be very durable as I wore them everyday of vacation while walking around Las Vegas.
I would definitely buy them again. Very good buy for the price

Didn't fit my narrow feet, but still excellent shoes at a great low price
Size: 11, Color: A Black
These are some of the lightest shoes I've ever seen, but the build quality appears to be excellent. They're tongue-less, like slip-ons, but unlike some, you can adjust the tightness with the laces. The body of the shoe is a mesh-like fabric, which allows good breathability and overall comfort, and the soles are a molded rubbery material with nice treads for grip.
I've been wearing a name-brand shoe made very similarly for a couple of years, and these are a very good likeness of them, at a much lower price. I like them because of the light weight and the fabric, which make them feel almost like you're barefoot.
Unfortunately for me, I have narrow feet, and these fit more like a D width shoe, with more room in the toe box than I can handle. I'm returning them for that reason. For people with "normal" feet, these make really nice, stylish and comfortable shoes. I don't know how well they would hold up to sports or running, but for walking and day-to-day wear, they're great.
I suppose I could grade them down because they don't fit my feet, but I find lots of shoes don't, and many makers use D width as the default for men's shoes. So I'm still rating them as 5 stars.

In a pinch they're worth it.
Size: 12, Color: D Grey
I got the dark gray color. They came exactly as pictured and are decently comfortable but as far as packaging it's very poor. They come in a small plastic bag all squished and deformed so you have to wear them a few times before they take shape again. For the price it's a great buy for some generic work shoes or something, the bottom tread doesn't last long at all though if you're expecting them to last a long time as it will be gone in a week or two if you wear them frequently. Buy them if you don't feel like spending a lot of money on shoes but want a new pair cheap.

Ladies, don't be afraid. Buy 'em. Trust me
Size: 9.5, Color: A Black
My elderly mother adores these. She had to have breathable awesome shoes for post-surgery and these fit the bill (and her feet!)
So i got some for me. Whoa. Comfort! And I love the slip-on ease, b/c sometimes I just need to go, go, and go some more. Love them in black, haven't had long enough for durability, but helpful for my mom in her physical therapy and they're holding up to the worst she can do to them.

Good overall shoe, great for basic needs
Size: 12, Color: A Black
These are nice shoes. I put $40 arch support insoles in mine, so I like them even more, but they were fairly comfortable even without. They fit well, though slightly large, and seem to hold up well. No real complaints, though made a bit cheaply.
