Sentry turns a phone you already own into a motion-triggered camera that works in the dark. Set it down, arm it, and walk away. When something moves, it records. When the movement stops, it stops. The clips land in your photo library, ready to review whenever you want. It records for you to watch later. It is not a live video feed โ€” you are not watching a stream, you are collecting what happened while you were not there. WHAT IT IS FOR Find out what your dog does to the sofa while you are out. See which animal has been visiting the garden after dark. Watch how a sleeping cat actually gets from one end of the room to the other. Point a spare phone at the garage overnight and check the footage in the morning. BUILT FOR THE DARK Most cameras give up when the light does. Sentry changes how the sensor reads a dark scene: it picks a binned format that gathers far more light per pixel, extends the shutter ceiling, and lets the frame rate drop so the shutter has time to stay open. The result is usable footage in rooms where the standard camera returns noise. The screen stays dark while it runs. Monitoring goes on for hours, often overnight, and a bright display would waste battery and light the room you are trying to film. RECORDING IS ALWAYS VISIBLE A red dot sits in the corner of the screen for as long as recording lasts. There is no setting to turn it off, because there should not be one. Photos play the standard iPhone shutter sound. NOTHING LEAVES THE DEVICE No account. No sign-up. No cloud. No subscription. Sentry contains no networking code at all โ€” recordings are written straight to your photo library and stay there. It works with the phone in airplane mode. HOW IT WORKS 1 tap โ€” photo 2 taps โ€” start recording 3 taps โ€” arm motion detection, which begins after 5 seconds and stops 1 second after movement ceases Swipe up โ€” cycle the rear lenses Swipe down โ€” front camera Two fingers, 3 seconds โ€” stop Shake โ€” settings Long sessions are saved in chunks as they record, so a flat battery costs you minutes rather than hours. RESPONSIBLE USE Record only where you have the right to. Laws on recording people vary by country and by state, and some places require the consent of everyone present. Sentry shows a recording indicator that cannot be disabled and plays the shutter sound on photos, so anyone who looks at the device can tell it is capturing. REQUIREMENTS iPhone and iPad running iOS 18 or later. Extended recording and motion detection use significant battery โ€” keep the device on a charger for long sessions. Video files are large, so check free space before a long run.

About

HyperSharp Camera

Read full description

HyperSharp Camera combines the physical 0.5x ultra-wide and 1x main rear cameras into one detailed wide-angle photo. The 1x image strengthens the center of the ultra-wide composition while keeping the wider field of view. Everything is processed privately on your iPhone. One shutter press. Two physical cameras. One fused result. KEY FEATURES - Simultaneous 0.5x + 1x physical-camera capture - Real detail from both camera images - Automatic alignment, color matching, and feathered fusion - High-resolution HEIF output - Full Wide Fusion and a seam-safe 4:3 Detail Crop - Clear on-screen guide for the 1x detail coverage area - Optional 3- and 10-second capture timers - Rule-of-thirds composition grid - Pinch, drag, and double-tap result inspection - Direct sharing for either selected result - No generative AI - No accounts, analytics, ads, or tracking - All processing happens on your iPhone - Unlimited capture and export, completely free HyperSharp requires an iPhone with physical ultra-wide and main rear cameras running iOS 17 or later. Camera support is checked on device at launch. The standard iPhone 15 is the current validated reference device. For the best result, start with a well-lit, mostly static scene and keep the main subject inside the detail coverage frame. Very close subjects, fast motion, and low light can reduce alignment quality.
