Sentry Motion Detector Camera vs PhoMeter

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 — 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 — recordings are written straight to your photo library and stay there. It works with the phone in airplane mode. HOW IT WORKS 1 tap — photo 2 taps — start recording 3 taps — arm motion detection, which begins after 5 seconds and stops 1 second after movement ceases Swipe up — cycle the rear lenses Swipe down — front camera Two fingers, 3 seconds — stop Shake — 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 — keep the device on a charger for long sessions. Video files are large, so check free space before a long run.

PhoMeter is a simple white balance meter for photographers, videographers, and creators. Use your iPhone camera to estimate the color temperature of your lighting in Kelvin and get a practical Tint indication for green/magenta correction. PhoMeter helps you choose a better white balance setting before shooting photos or videos. Point your camera toward a neutral surface or grey card, wait for the reading to stabilize, then lock and save the measurement. Main features: Live color temperature reading in Kelvin Tint indication for green/magenta white balance correction Stability indicator for more reliable readings Lock measurement before saving Add an optional note to each saved reading Measurement history Clean and fast interface for on-set use Useful for: Photo shoots Video productions Interviews Product photography Studio lighting setup LED light comparison Checking mixed lighting environments PhoMeter is designed as a practical white balance reference tool. It is not a professional spectrometer and does not measure CRI, TLCI, SSI, or full light spectrum data. For best results, measure using a neutral grey card or matte white reference under the light you want to evaluate.
