It’s nice that Ajax Systems moved their focus to the outdoor defense, because generally we can say that they have done its best indoors. New Ajax DualCurtain Outdoor is a fantastic device with an amazing feature set, and our favorite – exclusively fine-tuning, controlled on the back of the device.
Ajax DualCurtain Outdoor = 6x Curtain Motion Detector
How It Works in a Nutshell
Perimeter protection, infrared beams – nothing new. You get 2 invisible infrared beams coming out from the left and right sides of the sensor up to 15 meters away, and if the person crosses them at once, you get a triggering and the alarm signal subsequently. Although what matters more is the quality of how the basic technology was implemented, and there are things to say here.
How Is it Different
Instead of the traditional approach, when 2 separate parts, the IR transmitter and receiver, are installed at a particular distance away from each other while facing each other, creating 2 direct infrared beams between them. So instead of that, Ajax Systems made a single part. And the trick here is that these 2 areas on the sides are the parts from which the IR beams come out in 2 directions, the left and right relative to the device. That allows the Ajax DualCurtain Outdoor to cover around a 30 meters in length line, and on both sides, you can also see the anti-masking sensors, allowing the device to not get blinded by spray-paint or disabled by putting obstacles in front of it and go unnoticeably after that. Meaning it notices the change quite instantly. So these are the active elements themselves, and of course, there is the tamper button behind the bracket to prevent someone from taking it off the wall.
The Features
The next thing to talk about is the features and the fine-tuning. Taking the bracket off, you’ll get access to different toggles to adjust the distance and the direction of IR beams, the left and right sides, respectively. So these 2 in the middle are beam direction switches, and by switching these, the view zone of the optical system is able to shift 3 degrees horizontally, allowing us to adjust the correct view angle so that the detector’s field of view is not blocked by a column or downpipe and etc. Below there is the 5-step detection range scrollbar, respectively, from the near 4 meters to 5, 7, 12, and 15 meters away.
And these final 2 are here for a so-called Near Area Detection technology, which is an interesting one, and is designed to protect windows primarily. So the Ajax DualCurtin Outdoor emits a one more very narrow beam, directed 40 degrees down against the main sector, allowing detectors on both sides to spot movement closely to the detector’s body, addressing the typical problem of the blind spot, so common among such sensors.
1 / 2
The body was made to match an IP54 protection rate, operating temperature ranges supported are from -25 to +60 Celsius, with up to 95% humidity, so don’t worry, leaving it outside, it’s designed for that. The declared battery life is up to 4 years, which is quite a lot, compatible with even older Hub Plus, Hub 2, Hub 2 Plus, and Ajax Rex. The signal transfer range is 1700 meters in open space.
Activation and Use
The activation and use are as simple as they were with Ajax – you’ve got the Ajax Hub activated under your account, the Ajax app on your phone, you’ve got the device, and the device has a QR code on its back. So you go into the app, press the “add device” button, naming it the way you want, typically that’s the area it is protecting and scanning it, selecting a room and the group, and OK. Now you have 30 seconds to press and hold the power button next to the QR code, and you have it in your account.
The bottom line
Is that Ajax DualCurtain Outdoor literally outruns most similar modern detectors by a number of characteristics, is a great device for outdoor protection, and will do a perfect job if combined with the Security Camera.
