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.

Hallelujah… finally, I found the right pillow!!!
Size: Queen (Pack of 1), Color: White
I have spent a lot of money searching for the right pillow. I recently tried to Tempur-pedic that cost twice with this pillow cost. Tempur-pedic flattened out. I’ve had this pill for a few weeks now and it works wonders. I am a paraplegic. You can have a lot of neck problems. I love the fact that this pillow is adjustable. I immediately saw it was too stuffy and took a bunch out. It works perfect so glad I didn’t spend money on a $200 purple pillow. I read a lot of reviews and there were a lot of complaints about the odor. Mine did smell funny when it came out of the box. I immediately threw it in the dryer with a few bounce fabric sheets came out smelling fine. Pillows are a very individual thing, but I think for 40 bucks this pillow is worth a try. I’m really enjoying mine about one of those silk pillowcases to go over it and it sleeps cool and comfortable. Best wishes in your search for the right pillow. Update: I’ve been using this pillow several months and it continues. Give me a good night rest pain-free.. well worth the money. UPDATE: I have been using this pillow for three months and it still works great. It does not flat out or get hot..

Soft comfortable very good pillow
Size: King (Pack of 1), Color: White
I really love my new pillow it's great and comfortable. Yes, it has a little smell, but if you wash the pillowcase and put the pillow on the window for a day you won't notice anything anymore.

Best place for head
Size: Queen (Pack of 1), Color: White
Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes
