SECURITY SYSTEM ON THE WRIST— AJAX APP FOR WEAR OS SMARTWATCHES
With Wear OS smartwatches, Ajax makes essential security features accessible to a wider audience.
Instant access to spaces, security mode management, notifications, panic alarm — and more, all from the watch.
The Ajax app for Wear OS smartwatches (except for login) works independently of the phone, as long as the watch is connected to the internet via Wi-Fi or mobile network.

BUILD YOUR OWN SECURITY AND COMFORT SYSTEM WITH AJAX DEVICES
INTRUSION PROTECTION
The detectors instantly capture an intruder on your property, doors or windows opening, and glass breaking. As soon as a person enters a protected area, they will be captured by a detector from the MotionCam series, an Ajax camera, or a third-party camera.
VIDEO SURVEILLANCE IN THE SMARTPHONE
Ajax cameras, powered by proprietary video streaming technology, offer an integrated and efficient surveillance solution. Synchronized with system events, they grant users access to video data and enable customizable scenario-based recordings.
The video wall provides real-time views across large areas or multiple sites without system overload.
ONE CLICK, AND HELP IS ON THE WAY
In case of an emergency, press the panic button on the app to immediately transmit the event and smartphone coordinates to the security company.
FIRE DETECTION
Fire detectors notify of smoke and temperature spikes and promptly alert about dangerous carbon monoxide (CO) concentrations, which have no color, smell, or taste. Configure programmable actions for ManualCallPoint to open electric locks, cut power to devices, and activate ventilation with a simple press.
FLOOD PREVENTION
LeaksProtect notifies users of a pipe break, a washing machine leak, or an overflowing bathtub. WaterStop automatically shuts off the water if LeaksProtect or a third-party water leak detector is triggered. Create a scenario to shut off the water at a specific time or when arming the system.
AUTOMATION SCENARIOS
Change security modes according to a schedule, program outdoor lighting to turn on when strangers are detected on your property, or implement an anti-flood system. Manage gates, electric locks, lighting, heating, and electrical appliances.
PROFESSIONAL LEVEL OF RELIABILITY
The hub runs on OS Malevich, which is protected from failures, viruses, and cyberattacks. Thanks to the backup battery and communication channels, the system is resistant to power outages or the lack of Internet connectivity. The account is protected by session control and two-factor authentication. Ajax devices were tested for compliance with various requirements, rules, and regulations and have been rated as Grade 2 and Grade 3.
CONNECTING TO THE SECURITY COMPANY MONITORING STATION
The largest alarm receiving centers in 187 countries work with the Ajax security systems.

Very good security system, easy to set-up. When you get rid of the fob image in the app and use regular buttons instead, and add dark mode to the app as the horrible white is killing my eyes, it will be five stars. Edit: After 14 months of waiting, it finally happened. Thank you for making the app better. Update: It would be awesome if there was a simple app for Android watches with only basic features: (dis)arming, status, alarms.
App works fine, would be nice to be able to activate or deactivate the time schedule(s) from within the app, editing is fine in the pro app, but enabling/disabling should be possible from the regular app (with the correct permissions of course). Regarding the alarm itself, the displays unfortunately never light up when closeby (only within 1 or 2cm), and I can't get bluetooth phone arming/disarming to work.
The widget keeps losing the "space" and just reports "No spaces". Why does the app send "armed by..." adn "disarmed by..." notifications to the same user who performed the action? It is unnecessary and just noise - I know I just armed the system. At least five med an option to disable it, so I only get notifications when other users arm or disarm.
1) Lack of features - scenarious have very pure UI, I can't setup a lot of automations. Tuya app for example has a lot of smart home flexibilities. 2) when I am in elevator I can't leave offline requedtto disarm once connection is back (after 20 seconds) I can't enqueue any actions - if I am in offline they all go to dev null
Impossible to read Ts&Cs, privacy policy - there are no scroll bars. Got a notification from Play that Ajax now share location data with third parties No idea who or why, no way to find out. Even though notifications are on, there is an annoying popup that tells you Android can block them, check later or Learn More... it always comes back.
