Answers
Answer:
Kite flies in Oscillatory motion.
Explanation:
But sometimes it may also be linear motion.
Answer:
Explanation:
Motion is able to process images from many different types of cameras. The following is brief overview of the process to set up the Motion software.
Determine the type of camera
v4l2 devices which are most webcams
Composite capture cards
Network or IP cameras
The PI camera
Static movie files.
Specify the camera in the configuration files.
Start Motion from a terminal via the command line
Review the messages to ensure camera was found and press cntrl-c to exit
Specify a target_dir in the configuration file.
Enable the web stream in the configuration file
Specify a stream_port
Optionally turn off stream_localhost if you want to view the stream from a different computer
Enable the web control in the configuration file
Specify a webcontrol_port
Optionally turn off webcontrol_localhost if you want to view the webcontrol from a different computer
Specify which parameters to show on the webcontrol via webcontrol_parms
Optionally specify a stream_preview_method
The above should allow users to get Motion running and being able to view images via the stream. The next steps refine and finish a basic setup.
Refine how the image is captured with the image processing parameters
Specify the motion detection parameters
Execute scripts, Save pictures or movies.
The most difficult step in the above process will be the motion detection settings and specifying them to minimize the false positives. To assist this process, Motion provides the stream_preview_method option 3 which allows users to see side by side images of where the motion is occurring next to the regular image.
Specify stream_preview_method 3
Specify webcontrol_parms 2
Start Motion and in a web browser navigate to the webcontrol port
Try adjusting the threshold, noise_level, despeckle_filter and smart_mask_speed
Make sure to write configuration to file in order to save any changes.
Motion also includes a setup_mode which provides more values reported on the motion images and in the log to assist the setup.
The following are some additional topics which may be of interest during the initial setup.
Run automatically at start (Run as service)
Remove depreciated parameters warnings (Remove Depreciated)
List/include all possible configuration parameters (All parameters)
Video4linux devices must be installed per the requirements of the camera. It is out of the scope of this document to tell you how to do this and it depends on which type of camera. Once the camera is installed it will have the device name(s) of /dev/video0, /dev/video1, /dev/video2...
FreeBSD has a different naming scheme for pci devices that use the bktr subsystem. The bktr subsystem will report devices using a naming scheme of /dev/bktr0, /dev/bktr1, etc. These device may also need to use the other special device for the tuner. The tuner will need to be specified with the tunerdevice option as /dev/tuner0.
USB cameras take a lot of bandwidth. A USB camera connected to a USB2 port or hub consumes virtually all the bandwidth that the port can handle. Even with a small framesize and low framerate you should not expect to have more than one camera per USB controller. If you need more than one USB camera it is possible to add extra USB PCI cards to your computer. It is also possible that your computer has more than one controller for different USB slots. For example, if the computer has six USB ports, the three on the left may be on controller A versus the three on the right may be on controller B. In this situation, connecting two cameras to ports only on the left would not work due to excessive bandwidth. However connecting one camera to port on the right and the other to the port on the left may work since they are on different controllers.
Motion permits the use of video cards that have discreet input channels. Since USB cameras do not have input channels, the option input must be set to the value -1 for USB cameras.
Network cameras are set up via the netcam_url parameter. The latest versions of Motion support rtsp format which many cameras now stream. Some users have requested a list of the network cameras that will work with Motion. Since Motion can now process RTSP streams, almost all cameras are supported. Simply review the specifications of the camera and validate that RTSP or RTMP is listed. The cameras that will not work are those specifically sold to be integrated into proprietary software monitoring systems. When determining cameras, consider carefully before selecting a wireless camera. Cameras require a solid consistent signal and use a lot of bandwidth. Inconsistencies in the wireless signal can result in a poor user experience so the use of a hardwired camera is recommended.
