SentryBlack
Read full descriptionHide full description
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.

BlackShisa
Read full descriptionHide full description
BlackShisa gives a spare iPhone a job: watching over your parked car. It works two ways, and the first one is free. SECURITY LIGHT β FREE, NO CAMERA, NO PURCHASE A blinking LED tells anyone looking that the car is not unattended. BlackShisa turns your iPhone's light into that deterrent. The camera is never opened, so there is no recording and nothing to manage. - Set how long the light stays on and how long it stays off - Adjust brightness on devices that support it - Set a battery floor so the light stops before your phone dies, or ignore it while charging - Set a maximum run time - Dim the screen so only the LED shows This part of the app costs nothing and needs no account. EVIDENCE RECORDING β SUBSCRIPTION When you want proof rather than deterrence, start monitoring. BlackShisa watches for trouble and saves video around the moment it happens, aiming for footage where a plate or a face is readable. - Motion, sound and impact are watched independently, each with its own sensitivity - Recording starts BEFORE the trigger: the seconds leading up to an event are kept, not just the aftermath - Choose clip length: roughly 10, 33 or 60 seconds - Record at high resolution, up to 4K - Portrait or landscape, whichever way the phone sits on your mount - The same recorder works as a plain dashcam while you drive IF YOU WANT TO KNOW WHILE YOU ARE AWAY - Connect Gmail and BlackShisa emails you when something triggers, with the detection photo attached so you can judge it at a glance - Cap how many emails an hour, so a windy day does not fill your inbox - Connect Google Drive and clips upload on their own Both are optional, off until you turn them on, and use your own Google account. Drive access uses the drive.file scope, so the app can only touch files it created itself. BEFORE YOU START On iPhone, monitoring and recording run only while BlackShisa is open on screen. They pause when the phone locks or the app goes to the background. Keep the screen on and the app in front, use a mount, and give it power for long sessions. To stay discreet, you can switch the camera preview off while recording continues, or dim the display. The Security Light is not affected by this β it is meant to be left running. Available in English, German, Spanish and Japanese. THE SUBSCRIPTION, IN PLAIN TERMS - BlackShisa Monthly. Auto-renewing, one month per term. - Price depends on your country or region. In the United States it is US$6.99 per month. Your exact price is shown before you confirm. - New subscribers get a 7-day free trial. Nothing is charged during the trial. Your Apple Account is charged when it ends, unless you cancel at least 24 hours before that. - Without a trial, payment is taken when you confirm the purchase. - Renewal happens automatically within the 24 hours before the term ends, unless auto-renew is switched off at least 24 hours earlier. - Manage or cancel any time in your Apple Account settings. - The Security Light stays free whether or not you subscribe.

Verdict
The clearest difference is ads: BlackShisa at none against SentryBlack's shown. BlackShisa also leads on update cadence (daily vs fortnightly) and iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
