Secure Your Perimeter with Unmatched Precision

Introducing the AJAX DualCurtain Outdoor, a state-of-the-art wireless motion detector designed to provide a formidable, invisible barrier around your property. This device offers precise, bi-directional perimeter control without interfering with the movement of people already inside. Two independent optical systems with narrow viewing sectors allow you to meticulously adjust a detection zone of up to 30 meters (15 meters in each direction), effectively guarding windows, doors, archways, and fences while excluding common sources of false alarms.

Intelligent False Alarm Filtration

At the core of the DualCurtain Outdoor is the unique ELSA (Extended Live Signal Analysis) software. This advanced digital algorithm analyzes signals from two independent PIR sensors within each optical system. An alarm is triggered only when both sensors on the same side simultaneously detect human motion, effectively screening out false triggers from pets up to 80cm tall, swaying trees, and other natural interferences. This ensures that you are only alerted to genuine threats.

Eliminate Blind Spots with Near Area Detection

A common vulnerability in perimeter detectors is the blind spot directly beneath the device. AJAX solves this with its patented Near Area Detection technology. When enabled, the upper PIR sensor gains an additional narrow viewing sector angled 40 degrees downward, ensuring any attempt to cross the perimeter close to the detector's body is instantly identified.

Advanced Anti-Sabotage Protection

The DualCurtain Outdoor is engineered to resist tampering and sabotage. An integrated tamper alarm will trigger if the device is detached from its mount. Furthermore, advanced anti-masking sensors immediately detect attempts to obstruct the view by painting, covering, or placing obstacles in front of the lenses. The system also features protection against device forgery and detects communication loss with the hub in seconds.

Robust, Weatherproof, and Long-Lasting

Built to withstand the elements, the DualCurtain Outdoor operates flawlessly in a wide temperature range from -25°C to +60°C and is housed in an IP54-rated enclosure, protecting it from dust and splashes. It is powered by two pre-installed CR123A batteries that provide up to 4 years of autonomous operation, offering you long-term, reliable security.

Effortless Installation and Remote Management

Installation is made simple with the SmartBracket mounting panel, which allows for setup without disassembling the detector's body. Connecting to your AJAX hub is as easy as scanning a QR code with the app. All settings, including sensitivity and detection zones, can be configured and tested in real-time through the app, with the ability to reconfigure parameters remotely at any time.

This is a must-read for all those who are seeking answers.
Format: Paperback
If you can read only one of Robert Monroe's 3 books ("Journeys Out of the Body," "Far Journeys" and "Ultimate Journey"), "Ultimate Journey" is the one to read. Monroe's books chronicle his amazing learning experiences as his ability to travel out of the body develops and his capability to remember and to put these odysseys into words increases. Without laboring over material covered in the first two books, Monroe sums up his earlier adventures and then writes about his most recent and significant discoveries on this, his spiritual journey to understanding. If you have ever wondered if there is a God, why the Bible says that God is Love and in another place, shows God to be a vengeful being who orders the killing of many people, "Ultimate Journey" and the lessons taught to Monroe in his out-of-body state will help to clear up these questions. To say that "Ultimate Journey" will give you a whole new perspective on life, death and what lies beyond is an understatement. This is a must-read for those who are seeking answers! And, if at all possible, read all 3 books in order. "Far Journeys" is definately the most difficult to read, since much of it reflects Monroe's efforts to translate non-verbal communications from non-humans into English. But the information in that book is voluminous and well worth the effort to read it. Happy reading, fellow seekers!

YOU can actually LEARN to do this!
Format: Paperback
"Eavesdropping on Animals” by George Bumann really was a welcome break for me as I spend so much time outside in Nature. George is also amazing at being able to read Nature in a way I had never seen before. His insight via really listening & paying attention to everything around him, is so precise - he can literally know where animals are without seeing them. I got this book mainly because HE wrote it & I knew it would be interesting. The thing that surprised me was he actually teaches you how to do what he does (ie: know exactly where a wolf pack is traveling by hearing a certain coyote call & knowing the terrain). I started simply by really paying attention to all of the bird songs going on outside my window very early each morning & could finally hear ones that were repetitively there & was able to figure out what they meant by getting outside & sitting on my patio as I drank my tea. If you LOVE NATURE, you would so get into this book. It’s a great teaching guide, plus his stories are so cool! Entertaining & informative to read.

Will forever change your experiences in nature!
Format: Hardcover
I am an instructor in animal language in the wildlife ecology department at two leading universities and I can attest that George is an expert animal whisperer/linguist. I've had the pleasure of knowing him and hearing his stories, and this book is an outstanding gateway into understanding the behavior of animals. It will reveal a whole new world to you every time you step outside, whether you live in an urban area or next to a wilderness.
