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.

Spray lid didn't work
Size: 5 Fl Oz (Pack of 2), Style: SPF 70
One of the bottles didn't sprayer didn't work. it was so hard to push, we follow the instructions on the top of what to open or close it. The other bottle did work and was easy to push and spray. Disappoint with the product. I was out the country and I was needing the sunblock due to my husband skin cancer and the hotel didn't have sun-blocker.

Reliable protection that stays put during workouts!
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I’ve tried many expensive name-brand sunscreens, but this Amazon Basics version performs just as well, if not better. It’s become my go-to for morning runs and trips to the beach because it actually stays on even when I’m sweating. Why I gave it 5 stars: Non-Greasy Formula: Unlike other sport sunscreens, this one absorbs quickly and doesn't leave that heavy, sticky film on my skin. Actually Water Resistant: I’ve used it for laps in the pool and long hikes; as long as I reapply as directed, I haven't had a single sunburn. No "Sting": One of the best things is that it doesn't run into my eyes and sting when I start to sweat—a huge plus for runners. Great Value: You get a generous 8-ounce bottle for a fraction of the price of "premium" brands. The fact that it’s formulated without Oxybenzone is an added bonus for peace of mind. If you’re looking for effective, no-frills sun protection for an active lifestyle, you can't beat this. It’s a staple in my gym bag now!
