500.000 people in 90 countries around the world already secure their homes and businesses with Ajax!

Ajax security system is:

Detectors will notice any motion, door and window opening, glass-breaking. The moment someone enters protected area, MotionCam takes their picture. You and your security company will know what happened — no need to worry over nothing.

In case of emergency, press the panic button in the app, on the keyfob, or the keypad. Ajax instantly notifies all system users about the danger and requests help from the security company.

Fire detectors react to smoke, quick temperature rising, or dangerous amounts of the unnoticeable carbon monoxide in the room. If something’s wrong, the loud sirens of the detectors will wake up even the heaviest sleepers.

With Ajax, you won’t flood your neighbors. Detectors will let you know about the overflowing bathtub, washing machine leaks, or burst pipes. And a relay will immediately activate the electric valve to shut off the water.

Watch the security cameras in the app. Ajax supports quick integrations of the Dahua, Uniview, Hikvision, Safire equipment. Other IP cameras can be connected over RTSP.

Ajax Scenarios make your security system go beyond detecting threats and begin to resist them actively. Configure Night mode security schedule or turn off the lights automatically when you arm the space. Program your outdoor lights to spot the trespassers when they set foot on your property, or configure a flood prevention system.

Control gates, locks, lights, heating, and electric appliances from the app or with Button’s click.

Scan a QR code to connect a new device to the system. Mount the detector without opening its body. Cover facilities of any size using two-way radio communication at a distance of up to 2000 meters and 0 wires on the walls.

You can always trust Ajax. Hub operates on OS Malevich, a proprietary real-time operating system immune to viruses and resistant to cyber-attacks. Two-way Jeweller radio communication can resist jamming. The system operates even during the blackouts or loss of Internet connection in the building thanks to the back-up power supply and multiple communication channels. Accounts are protected with sessions control and two-factor authentication.

Ajax earned Grade 2 — the highest reliability grade available for the wireless security systems — after testing in five independent laboratories.

1150 alarm response companies around the world react to the Ajax security system alerts. And this number continually grows. Connect to an alarm response company right in the app.

Unusable Apple Watch app. Hard to use on iphone

Let me say first that I do like Ajax product for its reliability (battery and SIM card for hub), variety of sensors, ease of installation and price.

However the apps for phone and especially watch are written with utter disregard for usability. Cryptic error messages, very small font, very bad icons (a circle with a small opening, grey on white - impossible to see on small screen or without reading glasses). No explanation what night mode is. Errors when one locks (or unlocks) twice.
A font used is hard to read on My large Xr.

Apple Watch app is most problematic. It seem to require a phone nearby. I often go outside with watch on my hand and my main phone at home, while I approach the door, my watch senses wifi from inside and my phone too, still, it blinks
“Connecting..” message and cannot unlock. I had to resort to calling my girlfriend to unlock, or a remote control :)

And the watch app does require “hard press” on screen, which is totally non-intuitive. Also, it does not confirm locking and unlocking action by distinct text or sound - only that “broken” circle.

There are standard icons for On and Off status, or Locked/Unlocked. Why reinvent the wheel?

Developer Response ,

Good day!
Thank you for your interest in Ajax Systems!
Night mode is a mode that you can use to arm your perimeter and stay inside the house without any alarm triggers. More about Night Mode in the article:

The app on Apple Watch does not receive the information about the system state if the application on the smartphone was dumped off from the memory of the phone (when you swipe away the app in the task manager), thereby currently to properly transfer the states to the app on Apple Watch you should not dump off the app from the memory of the iPhone, leaving the app running in background.

At the moment, the timing of the implementation of a separate application for the Apple Watch is still unknown.

If you have any other problem with the application on Apple Watch - please contact our technical support

Thanks for the app

For now everything is stable. It would be great to have a control for turning security on/off with watch

Designed for unreadability?

I simply can’t believe the terrible UI design choices in this app. The combination of TINY font size and zero contrast of faint grey colored letters and numbers on an off-white background makes the notifications list unreadable without magnification. I literally have to screenshot the page, save it to photos, then open the image and use a spreading gesture to enlarge the image in order to read it. Horrible
