The GCXONE mobile app gives you secure, on-the-go access to your security monitoring platform. From your smartphone you can view live camera feeds, check site and device status, manage arm/disarm states, isolate devices, and monitor audio intervention activity — all from a single application.
This guide walks you through every screen of the app so you can get up and running quickly.
The GCXONE mobile app is available for Android and iOS. Search for NXGEN in the Google Play Store or Apple App Store and install it on your device.
Opening the app for the first time presents the Welcome screen. Login takes two steps:
Enter your sub-domain name — this is the unique identifier for your organization’s GCXONE environment. Tap Proceed when done.
You will be redirected to the secure login page. Enter your email address and password, then tap Continue.
Tip: Your sub-domain name is provided by your system administrator. If you are unsure what to enter, contact your support team.
After logging in you land on the Home screen. This is your monitoring overview — a quick snapshot of your entire estate at a glance.
Home dashboard showing customer count, armed/disarmed status, isolated devices, and audio interventions.
The Home screen displays:
Customers: total number of sites and customer accounts you have access to.
Armed / Disarmed: how many of your sites are currently in an armed or disarmed state, shown at a glance with colour-coded labels.
Isolated Devices: the count of any devices currently in isolation mode.
Audio Interventions (24 Hours): the number of audio intervention actions taken in the past 24 hours.
Use the bottom navigation bar to switch between Home and Site views at any time.
Tap Site in the bottom navigation bar to see a full list of all sites you have access to. Each site is displayed with its name. Use the Search Site field at the top to filter by name if you manage a large number of locations.
Site list — tap any site to open its detail view. Use the search bar to filter by name.
Tapping a site opens its overview screen, giving you a summary of everything configured at that location.
Site detail — Live Grid View, Total Events, Devices, and Schedules at a glance.
From the site overview you can access:
Live Grid View: tap to open the live camera feed for all cameras at this site.
Total Events (24 hrs): shows how many alarm events have occurred in the last 24 hours, plus a count of audio interventions.
Devices: the number of devices configured at this site.
Schedules: the number of active arm/disarm schedules set for this site.
Tapping Live Grid View from the site overview opens the camera selection screen. Here you can choose a layout and select which cameras to watch.
Live Grid View — choose a 2×2, 3×3, or 4×4 layout. Camera thumbnails show a preview of each feed.
At the top of the screen, four layout options are available: 2×2, 3×3, and 4×4 grids. Select the layout that works best for the number of cameras you want to monitor. Tap Fill the Grid to automatically populate the selected layout with all available cameras at the site.
Each camera tile shows a still preview image and the camera name. Tap the play button on any tile to begin streaming that camera. You can also tap the edit icon on a tile to adjust settings, or the delete icon to remove it from the current layout.
Tapping the play button on a camera tile opens the View Live screen, which streams that camera feed in real time. The fullscreen button (purple icon, bottom right) expands the view to fill the entire screen for a clearer picture.
View Live — tap the fullscreen icon to expand the stream to full screen.
Tip: If the stream takes a moment to load, wait a few seconds. Stream availability depends on your device's network connection and the camera's online status.
Within a site, tapping on any device from the Devices list opens the Device Details screen. This screen shows the device name, its active sensors, and the current arm state.
Device Details showing active sensors (RGB and Thermal cameras), the Isolate button, and a Swipe to Disarm banner.
Each sensor is listed with its name and type. A green Active badge confirms the sensor is online and functioning. Two actions are available directly from this screen:
Swipe to Disarm: when a site is armed, a green banner appears at the top of the screen. Swipe it to disarm the device. This is the quickest way to respond to an accidental trigger.
Isolate: tap the Isolate button to temporarily suppress alarm signals from this device. See the Isolation section below for details.
Isolation temporarily pauses alarm transmission from a device or an entire site for a set period of time. This is useful during maintenance, testing, or when planned activity at a site would otherwise generate false alarms. Disarm stops alarms from being received by the device.
To isolate a device:
From the Device Details screen, tap the purple Isolate button.
The Isolate dialog appears. Enter the duration in the Time field (for example, 15 min).
Tap Start. The device will be isolated for the specified time and will not send alarm signals during that period.
To isolate an entire site at once, scroll to the bottom of the Site overview screen and tap the Isolate button there. The same time-selection dialog appears and applies to all devices at the site simultaneously.
Tip: Isolated devices are counted on the home dashboard under Isolated Devices, so your monitoring team always has visibility of which devices are currently suppressed.
The table below summaries the main screens and what you can do in each.
