Uncompromised, Multi-Layered Entry Protection
Secure your property with the AJAX DoorProtect Plus, a next-generation wireless detector that offers three layers of security for any door or window. This device instantly detects opening, vibration, and changes in tilt, providing immediate notification of the first signs of an intrusion. It protects your home even when windows are left open for ventilation, thanks to its advanced accelerometer that registers changes in vertical slope, bangs, and any vibration, sending an instant alarm to the hub. Ready to operate straight out of the box, the battery is pre-installed for an effortless setup that takes just minutes.
Core Features of the DoorProtect Plus:
- Triple-Sensor Detection: Combines a high-end magnetic opening contact (reed switch) with a sensitive shock and tilt sensor (accelerometer) to guard against various intrusion methods.
- Advanced Accelerometer: Registers vibrations, impacts, and changes in vertical slope angle greater than 5°, making it ideal for protecting windows left open for ventilation.
- Jeweller® Wireless Technology: Ensures secure, long-range communication with the Ajax hub up to 1,200 meters in open space. The encrypted, two-way communication prevents jamming and device forgery.
- Exceptional Battery Life: Operates for up to 5 years on the pre-installed CR123A battery, minimizing maintenance and ensuring long-term reliability.
- External Detector Input: Features an external contact for connecting third-party wired detectors, allowing you to easily expand your security system's coverage.
- Effortless Installation: No need to disassemble the detector. It connects to the hub with a single click in the Ajax mobile app and mounts in minutes using the included SmartBracket.

Thin, Light, Very Functional - Fantastic tablet
Color: Gray, Size: 256 GB, Style: Tab A11+, Color: Gray, Size: 256 GB, Style: Tab A11+
First off you only get a tablet, an USB-C to USB-C cable, quickstart instructions and Sumsung care info. That's it. No charger, no nothing else. Even the screen doesn't come with a protector, the tablet itself comes in a fabric/paper like bag.
So advice: Buy a screen protector and/or case for this tablet! It's very thin and light weight!
The tablet itself is fantastic. It plays all the games so far I threw at it, even the graphic intense ones. Compared to some Chinese ripoffs, this shines like a champ. The 256 gigs of space is plenty and 8 gigs of ram help alot! Truly the tablet is great for my use - Playing games and watching videos.
I'm a little upset for the fact that it doesn't come with any charging device, but my phone's charger works fine. The USB-C to USB-C cable may come in handy (but my old PRO12 tablet uses the older usb port).
Overall I'm very pleased with it. The games I played on my Moto G phone play fantastic on the A11+ plus it can play much more. Also I don't stream so I put videos on the tablet. My old tablet I had to convert them to make the compatible. The A11+ and Android 16 shines here. It can play most all my videos without conversion, even 4k HDR videos natively! And the sound it great with four speakers as well!
Only downfall is the warranty. When I registered the tablet says something about the country of origin so I don't have warranty for the tablet.
Just remember to have a charger for it, screen protector and I recommend a case!

Quality but leaves something to be desired
Color: Gray, Size: 128 GB, Style: Tab A11+
The speed and the storage capacity are fantastic. It is not user friendly in terms of being intuitive where certain functions are as compared to the old galaxy. I\nWaste a lot of time searching for where various commands and functions are. They have decided to move them around.\nAnd there is no good search function

All you need in retirement
Color: Gray, Size: 256 GB, Style: Tab A11+
Great purchase in comparison with Fire and the Tab S. Does everything I need it to do: read books, email, pay bills, chat, etc. The price was right and it's a good solid tablet without too much complications. I have a Samsung Galaxy smartphone so both are complementary to each other. One comment, Samsung does not provide an actual plug, just the cable...not the best customer service act for sure but seems like all of them are doing it now. Otherwise, I'm pleased with it.
