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.

Finally a ball my power chewers cannot destroy
Size: Medium
I have two dogs, an American Bully and an American Pit Bull Terrier, and both of them love to chew. Most balls last a very short time around here before they are shredded or missing big chunks. This one has actually held up. They chase it, tug on it and sit and chew on it, and it is still in one piece with no pieces breaking off.
One of my favorite things is being able to put food inside. I add some kibble or small snacks, and they will happily sit and work on it for a long time. It keeps them busy, gives them something safe to chew, and they get a little reward while they play. When they are done, I just rinse it out and it is ready to go again.
If you have strong jawed dogs that usually destroy toys, this ball is worth trying. Mine really enjoy it and I feel better knowing they finally have a ball that can keep up with them.

My dog LOVES this ball
Size: Medium, Size: Medium
Does your dog destroy tennis balls in seconds?
Yes? Then your dog NEEDS this ball!
It's squishy like a tennis ball, fits in ball launchers (even the cheap ones) and bounces when it hits the ground.
My dog has been literally playing with this ball all day and not a single mark on it!
The only bad thing is that it does not float.
Definitely worth the money!
Put it in your cart!

Perfect for ball demolishers
Size: Medium
The dogs love the chuck it brand. I don’t know what it’s made of but they go crazy over them. Will not play with another ball. Wonder if it’s “laced” with an addictive scent. Have pits. Very durable. Not able to chew to pieces. Last for about 6 months before there is a small break. I keep a back up because when the ball goes missing the house is in chaos. 😆 🤪

Chuckit medium rebound balls
Size: Medium
My 8 month old German shepherd dog loves these balls. They are easy to throw, they bounce great, they are very chewable! She keeps one in her mouth most of the time. It satisfies her need to chew and she does not chew other things. She drops it in the water and lets the hole fill up and drinks that way. The only problem that has caused is suction in her mouth and difficulty in dislodging it for her. However, she would be lost without it!
