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.

Amazing product!

Kudos for the product and the app! This app is seriously awesome! Would have given a 5 star if I was able to control with Siri and/or homekit. But I have upvoted this feature on the website. Great work guys!

Good app, poor Outdoor MotionProtect performance

The Ajax alarm is a great concept. The Jeweller radio system connecting the detectors and the hub works well and the software is easy and intuitive.

However, I was very disappointed with the MotionProtect Outdoor sensors. They did not work nearly as well as the much older Optex VX40 outdoor sensors that I previously had.

The MotionProtect Outdoor readily give false alarms for plants moving in the wind and anti-masking alarms when it rains. Ajax has now introduced a hood to prevent rain causing an anti-masking false alarm. This is welcome, but it is disappointing that existing customers do not get these hoods for free, but have to spend more money to solve a defect of Ajax’s product. It is also disappointing that it was a problem in the first place - the sensor was designed to be outdoors.

I am a fan of the concept and think Ajax have done a great job. It is also great that they are introducing smart home functionality. However, an alarm system needs to be good at its core job in the first instance - detecting intrusion and distinguishing between intrusion and environmental factors. An alarm that is either switched off or with sensors bypassed to avoid false alarms is not much use, regardless of how easy and user friendly the system is to operate.

Great reliable product.

Well done to the team for creating such an awesome reliable product. Been using it for two months now and my only comment is that it would be nice to connect an external gsm antenna to the hub for better signal. The signal is only bad because I live in a area with poor signal, also a external antennal output would be useful when the fibre internet goes down.
