Motion Detector is a stand-alone surveillance tool for your iOS devices. Motion Detector automatically takes consecutive photos using the device's camera and performs sophisticated mathematics for motion detection. When motion is detected, Motion Detector can start automatic recording and/or Email notification, so you will have physical records of what has happened.

The app also supports sound detection using the device's microphone. The app will alert you when the microphone picks up a sound above a specified sound level.

If you have a paired Apple Watch, you can remotely view the motion detector camera from your watch. For example, you can set your iPhone in the living room, and remotely monitor and control motion detector from the bedroom.

Cumbersome to use and misses the mark

Starts recording immediately when you launch the app as soon as it detects motion. There should be a start stop function. It doesn't record as long as it detects motion, you need to set a record length. This doesn't seem well thought out. If I'm trying to catch an animal that goes in the detection area quickly, it seems it will record for the set record length until it detects motion again. I find it too difficult to use to be useful at this time.

Mr. Photo Addict ,

Motion detector doesn't work on my 10.2 iPhone.

Great ideas for features, but couldn't get it to work on iPhone 10.2. I tried selecting the area for motion, but it rises up 10% on the detection screen. So I made it lower to compensate for that. Only records or sounds alarm when I move the phone. Reset motion to whole image and restarted. It seems to detect motion in the levels, about 30%, but won't record unless I move the phone. Also, why isn't there an on-off activation button to arm/disarm the recorder? The only way I can stop it from triggering and recording while I'm trying to work on the settings is to shut down the app and restart.
Requests: if a working version gets updated, I would like the ability to record less than 1 minute, and the ability to have more than 3 sensitivity levels. Maybe just a line to let us enter the variable ourselves.



This app requires entering one’s personal email and the email password to get to one’s actual email server, such as Google, in order to send messages, and it doesn’t allow you to do that via the secure GMail protocol!

This is a serious data risk and utterly not fine by app developers!
