Good so far. Would love more integration with other devices. Also no Wear OS app is annoying.

App not working at Ulefone armor 18t android 13. Every time when i want to enter must restart phone, and don't get burglary notification!

3 ★, on 2025-03-13
would be better if there was a WearOS app. other than that it's a good as the iOS version.

5 ★, on 2025-03-12
App works as intended, layout is good and simple, adding components is super easy. I would have one functional request: to add a widget with single elements (e.g. just disarm, just arm ...)

5 ★, on 2025-02-24
Great app. I have some proposals: 1. Allow scenarios for temperature senzors to use a step of 0.1, e.g: trigger for 20.5 2. Allow devices reordering 3. Add android widgets to display temperature without accessing the app 4. Add android witdget to start/stop buttons or sockets

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. You and the security company will know what happened at the facility within just a few seconds.

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 Jeweller notifies users of a pipe break, a washing machine leak, or an overflowing bathtub. WaterStop Jeweller automatically shuts off the water if LeaksProtect Jeweller or a third-party water leak detector is triggered. Control WaterStop Jeweller and check its status from anywhere in the world via the Ajax app. 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. Activate ventilation, simulate home activity, or switch off potential ignition sources.

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.
