About
Turn your iPhone into a smart motion and sound alarm.
Vigil detects approaching people, vehicles, bicycles, movement, and unusual sounds—and alerts you when something needs your attention.
Whether you’re working a night shift, watching an entrance, protecting equipment, traveling, camping, or staying somewhere unfamiliar, Vigil gives you an extra layer of awareness using the iPhone you already have.
**SMART MOTION DETECTION**
Vigil can detect:
• People
• Vehicles
• Bicycles
• General movement
Point your iPhone toward the area you want to monitor and let Vigil watch for activity. When motion is detected, Vigil can trigger a loud alarm to get your attention.
Adjust the detection sensitivity to match your environment and reduce unwanted alerts.
**SMART SOUND DETECTION**
Vigil doesn't simply listen for noise. It first learns the normal sound baseline around you.
During setup, Vigil records the surrounding ambient sound level and uses it as a reference while monitoring. It then looks for sounds that stand out from the normal environment and can alert you when something unusual happens.
Sound detection is designed to filter common environmental noise, including birds and other recurring background sounds, helping reduce unnecessary alerts.
This gives you another way to detect activity—even when something happens outside the camera's view.
**WATCH ZONE**
Focus motion detection on the area that matters most.
Set a Watch Zone around an entrance, gate, doorway, walkway, vehicle, equipment, or any other part of the camera view you want to monitor.
**DETECT FROM A DISTANCE**
Vigil is designed for situations where you need to monitor an area from farther away.
Place your iPhone where it has a clear view and let Vigil watch for approaching activity.
**LOUD, IMMEDIATE ALERTS**
When Vigil detects motion or an unusual sound, it can trigger a loud alarm to get your attention.
You don't have to stare at your phone screen throughout your entire shift or monitoring session.
**PRIVACY-FIRST MONITORING**
Your camera feed stays on your iPhone.
Vigil does not require cloud video storage or uploading your camera feed to a server. Detection is performed on your device, helping keep your monitoring private.
**USE IT WHEREVER YOU NEED A WATCHFUL EYE**
• Security guards and night shifts
• Entrances and gates
• Construction and work sites
• Hotel rooms and hostels
• Camping and tents
• Luggage and personal gear
• Vehicles and equipment
• Temporary security monitoring
• Situations where you need to know when someone approaches
**DISCREET ALERTS**
Connect Bluetooth headphones or earbuds when you want to receive alerts discreetly without broadcasting an alarm to everyone nearby.
**SIMPLE SETUP**
1. Point your iPhone at the area you want to monitor.
2. Let Vigil learn the surrounding sound baseline.
3. Choose your detection and sensitivity settings.
4. Start monitoring.
5. Get alerted when Vigil detects movement or an unusual sound.
No dedicated security camera required. No extra hardware required.
Vigil turns the iPhone you already have into a smart motion detector, sound detector, alarm, and personal sentry.
Stay alert. Know when something is approaching.
