24HR OVERRIDE
Shutter or home. The first call is always yours.
The moment a sensor fires — on a shutter or at home — VoidStar calls, texts, emails or pushes an alert to your phone. Pick a GSM line with no subscription, or a cloud line with a portal, app and full event log.
Two questions, four devices. Pick both, see yours.

2:14 AM, a break-in in progress
Here's exactly what happens.
Watch it play out on loop below, or trigger the break-in yourself. Same three steps whether it's a shutter forced at 2am or a door tried while you're asleep upstairs.
01
Armed & quiet
Status LED glows steady green — shutter or wall-mount, same signal. Nothing to do but watch.
02
Break-in detected
Sensor fires the instant it's forced — shutter or door. LED flips red, siren sounds on-site.
03
Owner called, instantly
Phone rings — full-screen, past silent mode if it's a 24hr alert. Owner wakes, sees exactly what triggered it.
Two problems, one hardware family
Guarded shutters. Guarded homes. Standalone or cloud-connected.
Every VoidStar device wakes on a sensor event and gets word out within seconds. Choose GSM-only hardware that needs no subscription, or a cloud-connected line with a web portal, mobile app, and per-event logs.
Shutter Security
Mounts on any shutter. GSM calls & SMS, WiFi email, alarm siren, DND, 24hr override.

Two alert paths
Choose how the alert reaches you
Standalone hardware talks straight to a SIM card. Cloud hardware talks to VoidStar's servers, which fan the alert out across call, SMS, email and app — and keep a log of every event.

Why VoidStar
Built for shops, warehouses and homes that can't afford a missed alert.
No guard shift covers every hour. VoidStar hardware does — with a battery that runs for days on the standalone line, weeks on the cloud line, and a low-battery LED so you're never caught off guard.
