Turn your own iPhone, iPad, or Mac into a private home security camera. Set an old device to watch a room and its screen dims to a discreet dark monitor view β€” one that always shows a clear recording indicator, so it is never hidden β€” while it detects motion, saves event clips, and streams live to your other devices. Wake it any time with a press-and-hold. PRIVATE BY DESIGN Unlike typical CCTV apps, SentryBlack has no company servers watching your home. Your video stays on YOUR devices and YOUR own private iCloud β€” never our cloud, and never a third-party cloud you did not choose. β€’ Live view goes device-to-device and is end-to-end encrypted. β€’ If your network blocks a direct connection, you can optionally add a relay server of your own β€” the video through it stays end-to-end encrypted and the relay cannot decrypt it. SentryBlack provides no relay server, and this setting is off unless you fill it in. β€’ Cameras, motion alerts, and clips sync only through your private iCloud. β€’ No account, no sign-up, no tracking. USE ANY DEVICE AS A CAMERA β€’ The screen dims to a dark monitor view with an always-on "REC" indicator and timer β€” discreet and power-saving, but never blank. β€’ On-device motion detection saves a clip and snapshot of every event. β€’ Press and hold to wake the screen. MONITOR FROM ANYWHERE β€’ On another device signed into the same iCloud, tap Monitor to see all your cameras. β€’ Get instant push alerts with a snapshot the moment motion is detected. β€’ Watch live video β€” fastest on the same Wi-Fi, and end-to-end encrypted everywhere. SENTRYBLACK PRO The free version records with motion detection, sends cross-device alerts, and streams live on your Wi-Fi (with a small banner ad on non-camera screens; iPhone and iPad only β€” the Mac app has no ads). SentryBlack Pro adds: β€’ Cloud clip backup to your own iCloud β€’ Unlimited event history β€’ HD live view β€’ Person detection & motion zones β€’ Multiple cameras β€’ No ads Pro is an auto-renewing subscription (monthly or yearly) with a 3-day free trial. One subscription works on iPhone, iPad, and Mac. Payment is charged to your Apple Account; it renews automatically unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in Settings. Note: because Apple stops the camera when an app is in the background or the device is locked, a camera device must stay on and in the app while on duty β€” keeping it plugged in is recommended. Please use SentryBlack only to monitor your own property and spaces.
