Motion Detection. This special and extremely important function is independently programmable for each individual camera. By defining masking zones and sensitivity levels and thus optimising the analysis and recording stages and employment of the hard drive, only the images characterized by the actual presence of motion detected within the preset areas will be recorded and static images shall be discarded as insignificant. Moreover, this feature allows you to proactively manage the alarm, activating a warning to the Control Center, from which you can acquire images directly and decide on the possible intervention of on-site personnel.
Motion Detection. The ExacuTrack One uses a motion sensor to detect if the unit has been removed from a participant’s leg. When the tracking unit enters a motionless state, the ExacuTrack One reports the last valid location point to the central monitoring computer and generates a “No Motion” event.

Motion Detection. DetectMotion method Return the number between 0 and 100, reflecting the change detected in front of the camera. Call this method every second or two and check the result it Return. If the result is greater than 30, there is something moving in front of the camera. Experiment with this to see which value to use. Example Sub Timer1_OnTimer() If DNVideoX1.DetectMotion>30 then Beep MsgBox “Where are you going?” End If End Sub Text captions on video (time-stamp, etc.) To set date-time stamp in top-left corner on video, use: DNVideoX.SetTextOverlay 0, ”TIME”, 0, 0, ”Arial”, 14, RGB(255,0,0), -1 Sending video frames through network See also: Upload image to web server using FTP Properties: ServerMode Set this to TRUE to accept connections ServerPort Specify IP port number for connection ServerPassword Specify password for received frames Methods: ReceiveFrame Connect and get frame from remote server Events: ConnectionRequest This is invoked on a server when client connects At server side, use these steps:
Motion Detection. Device List Lists of all NVR and cameras Motion Detection Enable List Cameras with motion detection enabled and configured Video Preview Video preview of the selected camera from the above list Configuring Motion Detection The program can be configured to alert users when detecting motions in video streams recieved from one or more cameras. The user is able to define an area in a live video where motions in this area will trigger the program and send out alerts. An example of this can be to have a camera pointing to the doorway where no one comes through dur- ing the day. You can then define an area with the door included. This tells the program that any mov- ing object shows up in this area (a person walking in through the doorway) is considered abnormal and an alert should be sent to user for further action. To enable motion detection to certain cameras, drag a camera from the device list and drop it on to the motion detection enable list. The camera will then show up in the motion detec- tion enable list. You can then set sensitivity of the motion detection. Click “Set” to display the video in the video preview window in which you can define an area for motion detection. Chapter 6 Motion Detection Users and Groups Users and Groups Configuration The section allows users to add new users and cus- tomize each of their access privilege by assigning them to different user groups. The purpose of this function is to limit the number of people to have ac- cess to the program, hence, having access to view live videos, playback videos or altering settings of the program. Once you add users to the program, you will be prompted to enter the username and password of a valid user account. * There is no user account configured for the program by default. The privileges of the “Admin” and the “Guest” groups are not configurable and the “Guest” account is configured with the “view only” privilege”. Add a New User To add a new user, simply click on the “add new user” button available at the upper-right hand corner in the “User/Group Config” page. Add a new user This opens up a new window for you to enter the detail information of the user you are creating. * The “Username”, “Password” and “Confirm Password” fields are re- quired when creating a new user account. The rest of the fields are optional. * You can click the “Check” button to check if the username you are cre- ating for the new account has been used by another account. A “+” will appear next to the group indica...
Motion Detection. This allow user to enable motion triggered alarm. When this box is checked, a snapshot with selectable zones will appear below the setting. You can mark areas of interest (representing in red), the IPC will then record and send back video clip to NVR or other platform if the objects in picture changes or motion activities detected. IPC with alarm enabled will save you storage space and ease up searching for video file.
Motion Detection. This section describes a fairly simple procedure for tracking and recording patient movements during a PET scan. See Figure 2.2 for an illustration of the tracking device mounted on the rear of the scanner gantry and the reference tool mounted inside the scanner.
