# The MOBOTIX Activity Sensor **Avoid false alarms simply and efficiently** The **[MxActivity Sensor](https://www.mobotix.com/en/mxactivitysensor)** from MOBOTIX is an advanced video motion detection technology specifically designed to drastically reduce the number of false alarms. Here are some key features: 1. **Motion detection** : The sensor specifically registers the movement of people and objects and ignores irrelevant changes in the image, such as changes in lighting or the swaying of trees in the wind. 2. **Reduction of false alarms** : Targeted detection of relevant movements can reduce the number of false alarms by up to 90 %. 3. **Simple configuration** : The sensor is quick and easy to configure. All you have to do is define the desired image areas and directions of movement that trigger an alarm. 4. **Robustness** : The MxActivity sensor delivers reliable results even in the event of external interference, such as heavy rain or moving objects. 4. **Integration** : The sensor is integrated in MOBOTIX cameras and works with firmware version 4.1.6 or higher. This technology is particularly useful for applications where precise and reliable motion detection is required, such as monitoring car parks or buildings. **Video explaining the basic settings in the browser:** [![](https://canada1.discourse-cdn.com/flex030/uploads/mobotix/original/2X/0/0eeacac7a1a8ab63b0fa507600530c0ee882ac35.jpeg "Setting Up Your First MOBOTIX Camera Activity Sensor") ](https://www.youtube.com/watch?v=-FcBN6XueNw) The settings can also be changed using the [MOBOTIX MxMC](https://community.mobotix.com/t/mxmc-since-version-2-0-advanced-config/6059) durchführen.

It specifically recognises relevant movements and ignores irrelevant changes in the image. (as described above) ### MxActivity Sensor 2.0 Version 2.0 of the MxActivity sensor takes the relative size of the detected object into account. The parameterisation of object size near and far can be defined separately. This prevents small objects such as animals in the vicinity from being recognised as persons: - Increased precision\*\*: Improved motion detection algorithms that distinguish even more precisely between relevant and irrelevant movements. - **[Introductory video](https://www.youtube.com/watch?v=5cJM9p0Y9EU)** - Activity Sensor 2.0 in Action: [![](https://canada1.discourse-cdn.com/flex030/uploads/mobotix/original/2X/2/2bf2361664049ee9c6722a6c7f9b1e47b0006645.jpeg "MxActivitySensor 2.0 by MOBOTIX - Dach (Demo Video)") ](https://www.youtube.com/watch?v=vCXw8q8zxuw) ### MxActivity Sensor 2.1 Version 2.1 builds on the improvements of version 2.0 and offers additional functions: - Reduced false alarms\*\*: Further optimisations that reduce the number of false alarms in dark and “noisy” images. The most important points during configuration: - The **detection range** of the activity sensor should cover the area to be monitored (not too small) - Define **exclusion areas** : Mark areas that could generate false alarms (e.g. road, long swivelling branch in the field of vision, flags, etc.) with a rectangle; these areas are then ignored with an exclamation mark in front of them. - Define **object size** for objects **close** to the camera - Define **object size** for objects **far** away - **[Video](https://www.youtube.com/watch?v=ALWFxQXdbVc)** shows the definition of near and far. Please also note the practical tip - > **Practical tip:** For people, always set the window slightly smaller than the person themselves (approx. torso with head without arms and legs); this was not taken into account in the video! - Set **dead time** sensibly This is what it looks like when it is configured correctly: [![](https://canada1.discourse-cdn.com/flex030/uploads/mobotix/original/2X/4/4e3dfe4ee629c523ef944b2c83b3d3bb17139448.jpeg "MxActivitySensor 2.0 by MOBOTIX - Perimeter (Demo Video)") ](https://www.youtube.com/watch?v=5H884YjNgz4) ### MxActivity Sensor AI The latest version, the [MxActivity Sensor AI](https://www.mobotix.com/en/mobotix-certified-apps/activity-sensor-ai), integrates artificial intelligence for motion detection: - **AI-supported detection** : Use of AI for even more precise detection of relevant movements and further reduction of false alarms. **Self-learning systems** : The sensor can adapt to different environments and conditions and continuously learn to improve detection. > **Available in the MOBOTIX ONE camera as an APP!** **Configuration in the camera explained in detail:** > [@Setup ActivitySensor ONE-App in the MxMC - EN](https://community.mobotix.com/t/setup-activitysensor-one-app-in-the-mxmc-en/9713): > > Support for the MOBOTIX ActivitySensor ONE app in the MxMC Powerful search filters support the reliable and intelligent event detection of the ONE camera In the forensic search (Smart Data Search) of the MxMC, the results data from the MOBOTIX ActivitySensor ONE app is supported and the user can conveniently optimise the results list with the help of search filters and parameters and find the desired incident more quickly.
