Shutter-mount
- 01 Clips onto the shutter's bottom rib — fits any level, any width
- 02 Status LED, visible from outside the shutter
- 03 Removable battery cell — pull it, charge it, slot it back in
- 04 Sealed housing, no wiring to the premises
From sensor to phone, in seconds
Two devices. Two ways the alert reaches you.
Both lines start the same way — a sensor fires and the device wakes up. What happens next depends on whether you're running the standalone GSM line or the cloud-connected line.
GSM Path
Shutter Security & Home Security
01
Sensor firesShutter movement or door/window interrupt wakes the device.
02
Device dials out over GSMCalls and texts the configured numbers directly through its own SIM — works even without WiFi.
03
Email over WiFi (if available)If the device also has WiFi configured, an email alert goes out alongside the call.
04
Siren + LEDThe on-device alarm sounds and the status LED shows the trigger state.
05
DND / 24hr checkCalls are suppressed during your configured Do Not Disturb window — unless the event is flagged 24hr, in which case it rings through regardless.
Cloud Path
Shutter Cloud Security & Home Cloud Security
01
Sensor firesDevice wakes and connects to your configured WiFi network.
02
Device authenticates to the cloudA layered check confirms the device is genuine before anything else happens.
03
Cloud classifies the eventThe backend reads what kind of event this is and which device it came from.
04
DND / 24hr checkThe cloud checks your DND schedule. Events flagged 24hr always ring through, DND or not — DND only ever suppresses calls, never email.
05
Every channel, at onceCall, SMS, email and app push all go out to every configured contact; the event is written to your log immediately.
Real numbers, not marketing rounding
What "instant" actually means
The ESP32 inside every VoidStar device has a wake window of roughly 2.2–3.4 seconds — that's the hard constraint the whole system is built around, not a marketing estimate.
0.0s
Sensor trips — shutter forced or door/window interrupt fires.
~2.2–3.4s
ESP32 wakes from deep sleep and connects — to GSM or to WiFi, depending on the line.
Seconds later
Call, SMS, email or app push reaches you — every configured contact, every enabled channel.
Two mounts, same device internals
Shutter-mount or wall-mount — you're choosing where it lives, not what it does
Wall-mount
- 01 Fixes to a wall or doorframe near a socket
- 02 Status LED, same signal language as the shutter unit
- 03 Mains power lead, with battery for automatic backup
- 04 No manual charging — it switches over on its own
Two settings buyers ask about most
DND schedule & 24hr override, in plain terms
DND Schedule
Set quiet hours — say, your own sleep hours — during which the device won't ring your phone for routine events. Email alerts still go out during DND; only the call is held back.
24hr Override
Mark specific alert types as 24hr-priority and they'll ring through at any hour, DND or not. Meant for the events you'd want to know about even at 3am — an actual break-in, not a routine sensor check.
