Screen 47 went blank

You found out on Monday.
Zentari gives your NOC team a single view of every screen, terminal and kiosk across your estate — so you know the moment connectivity degrades, not when a client calls to complain.
Three things that go wrong when SIM connectivity is an afterthought.
The screen your client pays for goes blank. For days.
Digital OOH and in-store campaigns are sold on guaranteed uptime. When a single-network SIM drops in a location with poor coverage from that carrier, the screen goes dark. Without real-time monitoring, it can stay dark for days before anyone notices — and by then the SLA conversation is already uncomfortable.
The till that can't process payments during a Saturday rush.
A POS terminal that loses its SIM connection can't reach the acquiring bank. Every contactless tap, every card insertion, returns a decline. The queue builds. Staff scramble. Customers leave. The fix — a SIM that automatically fails over to a second network — is simple. Not having it isn't.
The kiosk that needs a field engineer for a problem a SIM command could fix.
Self-service kiosks in retail parks and transport hubs are expensive to visit. Without fixed IP addressing and remote access, every connectivity-related fault requires a physical callout. With Zentari, your team can reboot the connection, run diagnostics and push a SIM command from the portal in under a minute.
One SIM estate.
Every device type you operate.
Retail and out-of-home operators typically run a mix of device types across their estates — high-bandwidth signage players, low-data POS terminals, and always-on kiosks — each with different connectivity profiles. Zentari manages all of them in one pooled estate so your most data-hungry screens don't push low-consumption devices into overage.
Activate SIMs at the pace of your rollout. New store opening? Activate its SIMs on fit-out day via the portal or API. Closing a location? Suspend them instantly — billing stops immediately.
Digital Signage Players
High-bandwidth 4K content delivery, remote content pushes, and uptime monitoring. Pooled data absorbs burst usage during content update windows.
POS & Payment Terminals
Low-data, always-on payment processing over a private APN. Routing card data off public internet infrastructure can simplify your PCI DSS scope.
Self-Service Kiosks
Fixed IP for remote diagnostics and firmware management. Reboot a stalled kiosk from the Axis Portal without dispatching a field engineer to the site.
Interactive & Wayfinding Displays
Touchscreen directories, interactive retail displays and wayfinding units in high-footfall locations. Multi-network resilience keeps them responsive when the building's shared WiFi is overloaded.
Managing 500 devices shouldn't take five times the work of managing 100.
Live Estate View
See the connection status of every device across every location in a single dashboard. Filter by site, device type, or network.
Instant Alerts
30-minute usage polling flags connectivity changes before they become outages. Get email alerts the moment a screen degrades — not after a client complaint.
Remote Commands
Send SIM commands, reboot connections, and run diagnostics directly from the portal. Most connectivity faults resolved without a site visit.
CMS Integration via API
Connect SIM lifecycle events to your content management system. Automate activation on new store openings and suspension when locations close.
One pooled data plan across your entire estate.
High-bandwidth signage players consuming gigabytes per month are offset by low-data POS terminals. One shared pool with Watchdog auto-suspend means your per-device cost stays flat as your estate grows — whether you operate 50 screens or 5,000.
