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.

After 4 weeks using the app on a Samsung s23 some good and bad things. Biggest issue is that notifications speed is random. I set all the settings everywhere to ensure the app does not sleep etc. etc. but still sometimes it takes seconds and sometimes minutes. This is not great for the Ajax doorbell.

Ajax Awesome. Ajax app okay, but missing features: 1 - The ability to order devices how you want them. 2 - The ability to set the automations screen as the default instead of zones 3 - The ability to change device ordering on the automations screen. It would be great to give the use the ability to group items/hide items here as well. 4 - The ability to change the default device image. For example, a building with 20 relays, visually sees 20 relays and not what the relays control. 5 - &more...

Nearly perfect! My main suggestion is regarding the 'Arm' shortcut created from the home screen (via long-pressing the app icon and dragging 'Arm'). If the alarm fails to arm due to open sensors, the app currently doesn't provide a notification. It would be a significant improvement if, in such cases, the app automatically opened to display the open sensors, similar to its behavior when arming from within the app itself
