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. Features: * Motion detection using sophisticated mathematical models. * Sound detection. * Automatic Email notification. * Automatic trigger recording of subsequent photos. * Custom motion area selection. * Recording playback. * Remote viewing from Apple Watch. ## Key features - Motion detection with mathematical models - Sound detection - Automatic email notifications - Triggered photo/video recording - Custom motion area selection - Remote Apple Watch viewing ## Recent user reviews (10 of 30) All indexed reviews: https://appshunter.io/ios/app/motion-detector/id331443079/reviews.md ### 1/5 — Trying to scam you *2020-03-30, version 5.0* If you bye The app it may be done but DO NOT ENTER ANY OF YOUR ICLOUD OR EMAIL INFO THEY ARE TRYING TO SCAM YOU AND STEAL YOUR MONEY!!!! ### 1/5 — SECURITY RISK FOR PHISHING *2019-04-19, version 5.0* 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! I WAJT A FULL REFUND NOW! ### 2/5 — Cumbersome to use and misses the mark *2017-09-05, version 5.0* 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. ### 3/5 — Motion detector doesn't work on my 10.2 iPhone. *2017-02-01, version 5.0* 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. ### 2/5 — Not good for monitoring *2016-04-04, version 4.3* It works as concept but far away from my need. Even if I set high sensitivity it won't detect small moving objects at all ### 5/5 — Just what I needed!! *2015-09-30, version 4.2* I was looking for a cheap way to find out which one of my three cats was urinating on the carpeting. I wanted to be able to catch them in the "act". I didn't want to spend a lot of money on surveillance cameras so I was really happy when I found this app that allowed me to use my iPad as a camera. I wanted motion detection because I didn't want to go through hours of video tape. It even sent me still photos by email whenever the camera detected some motion. Then I could go back to the iPad and view the video that it took if it was one of the cats in the still photo. So simple to use. I highly recommend this app if you just need some photos and video caught by motion detection. It also has an option to start videotaping when there is a sound. But I didn't need that. Filled the bill for me! ### 5/5 — Really good *2013-11-24, version 3.0* It works exactly as it should be lots of settings, just need to add arm button so it doesn't record as soon as it starts up xD ### 3/5 — Ok *2013-08-04, version 2.2* Not sensitive enough. ### 1/5 — It's Junk *2013-07-24, version 2.2* No matter which combinations of settings are used, this app does not work on an iPad 3. There is no way to contact the company that made this app as the support email address on their website doesn't accept mail. Clicking on the Report a Problem link takes you to an advertisement for another of their products. What a waste of money. Run away! Run away now! ### 1/5 — Review *2013-06-09, version 2.2* Not worth $1.99. Actual motion detection is not very sensitive even with high sensitivity on. Email is .JPG only not .MP3. One minute recording wastes a lot of memory space and creates many dead videos. ## Frequently asked questions about Motion Detector ### What does the Motion Detector app do?
