Sentry Motion Detector Camera vs Technicam by TetsuoLab

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.

See what happens when you’re not watching. Technicam turns your iPhone into an intelligent observation camera built for monitoring a scene, detecting activity and capturing the moments that are easy to miss. Point it at the sky, a distant horizon, your garden or any fixed scene. Technicam can watch continuously, react to movement and build a record of what happened. FOUR WAYS TO CAPTURE VIDEO Record directly with quick access to the camera controls you need. MOTION DETECTION Arm Technicam and let it watch for you. When meaningful movement appears, Technicam can automatically capture the event. Choose scene profiles for different conditions, then fine-tune sensitivity, focus, exposure and advanced detection controls when you need more precision. SLOW SHUTTER Go beyond ordinary frames. Slow Shutter combines information across time to reveal light trails, movement and details that a normal photo may miss. Different processing modes create genuinely different results, from visible motion trails to cleaner low-light observations. TIME LAPSE Compress a long observation session into something you can review in moments, with flexible capture controls for different subjects and conditions. BUILT FOR OBSERVATION • Automatic motion-triggered capture • Day, night, sky and custom detection profiles • Manual focus, shutter and ISO controls where supported • Motion tracking and detection regions • Ignore areas to reduce unwanted triggers • Slow Shutter processing modes • Time Lapse controls • Capture Log for reviewing events • Event previews, notes and classifications • Motion-trail images • Reports and export tools • Video and audio capture where available • Location information for captured events when enabled • Tools designed for fixed-scene and night observation SIMPLE ON THE SURFACE. POWERFUL UNDERNEATH. Technicam 2.0 has been redesigned around a camera-first interface. Swipe between Video, Motion Detection, Slow Shutter and Time Lapse.
