Secure Your Space with Intelligent Glass Break Detection

Introducing the AJAX GlassProtect Jeweller, a sleek and sophisticated wireless detector that provides an essential layer of security for your home or office. This compact device is engineered to instantly detect the sound of breaking glass from up to 9 meters away, ensuring that any potential intrusion through windows or glass doors is immediately identified. Its advanced technology distinguishes it from the noise of everyday life, offering you peace of mind without the inconvenience of false alarms.

Advanced DualTone False Alarm Prevention

At the core of the GlassProtect Jeweller is the innovative DualTone two-factor detection algorithm. The device's sensitive electret microphone listens for two distinct sounds in sequence: the low-frequency sound of an impact followed by the high-frequency sound of shattering glass. This intelligent analysis ensures the detector only triggers for genuine threats, ignoring common sounds like thunder, barking dogs, or passing traffic that can cause false alarms in other systems. You can adjust the sensitivity through the Ajax app to perfectly tailor it to your environment.

Unrivaled Wireless Reliability with Jeweller Technology

The GlassProtect operates on AJAX's proprietary Jeweller radio technology, guaranteeing a secure and reliable connection to the hub at a distance of up to 1,100 meters. This encrypted, two-way communication is protected against jamming and forgery, providing a tamper-proof link that you can depend on. The system provides instant notifications directly to your smartphone and your security company in the event of an alarm.

Effortless Installation and Extended Battery Life

Designed for convenience, the GlassProtect Jeweller is ready to work straight out of the box. The battery is pre-installed, and connecting it to your Ajax hub is as simple as a single click in the mobile app. The included SmartBracket mount allows for quick and easy installation without needing to disassemble the detector. With an impressive battery life of up to 7 years, this detector offers a truly set-and-forget security solution.

A must-read for OBE enthusiasts
Format: Paperback
Projection of the Astral Body I recently read The Projection of the Astral Body by Sylvan Muldoon and Hereward Carrington, and it’s a captivating classic! Published in 1929, Muldoon’s firsthand accounts of out-of-body experiences (OBEs) are vivid and pragmatic, detailing his involuntary projections from age 12 and experiments thereafter. His explanations of the astral cord, travel sensations, and the hypnagogic state are clear, avoiding excessive mysticism. Carrington’s scientific editing adds credibility. My only critique: the dated language can be dense, and the small font in some editions strains the eyes. A must-read for OBE enthusiasts

Basic Fundamentals of Astral Projection
Format: Paperback
This book is full of great information about Astral Projection that is presented in a straightforward manner. I have read many books and articles about this subject over the past 10 years. Many are full of scraps of insight that are glued together with abundant amounts of repetition and babble. Mr. Sylvan Muldoon, like many of the great occultists from the early 20th century, has created a work that will refresh the weary, "would-be" traveler by keeping his explanations short and concise. His theory on the astral body being ruled by the subconscious conveys why auto-suggestion is extremely important when attempting separation. He provides the traditional method of maintaining the hypnagogic state via the raised forearm of which Robert Monroe echoes in his own exercises 40 years later. His "Dream True" method is unique to any of the techniques that I have read about in the past. I cannot recommend this book enough for anyone who is attempting the art of Astral Projection.

Good book, quite through
This was quite an in depth analysis on the subject which the author writes from his own experiences, and it seems quite obvious that he is not making any of it up. His explanations can be tedious at times, but this is in an effort to present the information as scientifically as possible, trying to answer any and all doubts and questions that would arise to the skeptical minded person. If you are interested in astral projection, I have never read a more revealing book on the subject.

Astral Projection From A Century Ago
Format: Kindle
This book is roughly a century old. With that comes a slightly different language but not one too difficult to follow. Some of the things that stuck out for me were: * The astral cable or “silver cord.” * The subjects of possession and the demonic. * The detailed suggestions for astral projection. This book could have used some editing ( there is the occasional “I” out of place) in spots but it remains very readable and helpful for understanding what astral projection is and different facets of it.
