Instant Intrusion Detection for Every Entry Point

Secure your home or office with the AJAX DoorProtect, a sophisticated wireless opening detector designed to be your first line of defense against intrusion. This sleek black device instantly notifies you of the first signs of a break-in through a door or window. It utilizes a high-end, British-made reed switch, tested for over a million openings, to reliably detect when an entry point is breached. Ready to operate straight out of the box with a pre-installed battery, it can be set up in minutes and connected to an Ajax hub with a single click in the mobile app.

Uncompromising Wireless Security

The DoorProtect operates on the proprietary Jeweller radio technology, ensuring a secure and reliable connection to the Ajax hub up to 1,200 meters away in open space. This two-way communication protocol features block encryption and protection against jamming and forgery, making your security system virtually impenetrable. The system regularly checks detector status, with polling periods as frequent as every 12 seconds, to ensure constant protection. With an incredible battery life of up to 7 years, you can enjoy peace of mind without the hassle of frequent battery changes.

Versatile and Tamper-Proof Design

The AJAX DoorProtect is engineered for versatility and resilience. The set includes two different-sized magnets (a small one for gaps up to 1 cm and a large one for up to 2 cm), allowing for flexible installation on various types of doors and windows, including those with metal frames. An integrated tamper alarm will immediately notify you of any attempt to dismantle or detach the detector from its mounting panel. For expanded security, an external terminal is available to connect a third-party wired detector, effectively turning the DoorProtect into a versatile transmitter module.

Key Features:

  • Detects door or window openings via a high-sensitivity reed switch.
  • Long-range Jeweller radio technology for stable communication up to 1,200m.
  • Exceptional battery life of up to 7 years from a pre-installed CR123A battery.
  • Tamper-resistant body that alerts on attempts to detach or open the device.
  • Includes two magnets for installation on different frame types and gap sizes.
  • External input for connecting third-party wired detectors.
  • Simple, tool-free installation with the SmartBracket mount.
  • Easy configuration and control through Ajax mobile and desktop apps.

Soft and Smooth!
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
This product feels fantastic when you put it on. A little goes a very long way so you get a lot for your money. It does work great after just lightly drying your face. There isn’t much of a smell, which I prefer. I have very sensitive skin and this is so soothing to use. I’m also in my late 40’s so the soft, plump and smooth look achieved after using this is so nice. If it makes your skin greasy at all you are using too much.

Buy!! Worked well for my eczema
Love love love this product!! It’s AMAZING for my winter skin. The consistency is thick enough to deeply moisturize and keep my skin hydrated all day long. It made my skin super clear, smooth, and healthy-looking. It also really helped clear up my eczema, especially the eczema and dry patches on my face. My dry spots became so much smoother and less irritated after using this consistently. The jar lasted me a good while, which I loved since I use moisturizer constantly. There’s no fragrance, the application is super easy, and the consistency feels sooo nice on the skin. It absorbs really well and leaves my skin feeling soft and glowy. It honestly worked so well that I didn’t even need to use primer before my makeup anymore 😭 that’s how good this product is!! I will always repurchase, especially during the winter 💕

Buying more!!!
I recently tried Tele Honeyball Face and Body Moisture Cream, and I’m honestly impressed. From the first use, it felt incredibly rich without being greasy, which is a hard balance to find. It absorbs quickly and leaves my skin feeling soft, smooth, and deeply hydrated all day. What I really love is how versatile it is—I’ve been using it on both my face and body, and it performs beautifully in both areas. My skin tends to get dry, especially with changing weather, and this cream has made a noticeable difference in keeping everything moisturized and healthy-looking. The texture is luxurious, and a little goes a long way, so it feels like a great value too. If you’re looking for a reliable, high-quality moisturizer that actually delivers on hydration, this one is definitely worth trying.
