Configuring motion detection To set up motion detection, click on Setup button, and then select the Alarm tab. (Note: motion detection may not be properly for an outdoor area where light changes.) Alarm settings Trigger the alarm if there're over x % changes The software triggers the alarm actions if the percentage of changes between the scenes (pixel changes) exceed the value. You can use the percentage change indicator in the software as a reference to adjust this setting. Mark motion detected areas Check this box if you wish Watchdog to mark the motion detected areas. Ignore light switch or camera shift NetCamCenter won't see light switching as an intruding event if you turn this on. Activate alarm after x minutes You may want to set up the delay time to avoid alarm being activated when you leave. Enable pre-alarm, buffer for x seconds Check this box to enable pre-alarm. Enter how many seconds of video should be kept in buffer for prealarm. (Note: audio is not supported with pre-alarm recording.) Please note pre-alarm does not come for free. Software has to temporary store the images on the hard drive and this consumes other computer resources as well. The longer the pre-alarm time you set, the more hard drive space is needed. Reset alarm status after x seconds The software will be set to non-triggered status after no motion for x seconds. Delete alarm log To delete the alarm log, click Delete alarm log. Motion detection rate x frame/sec Adjust motion detection speed. The faster the better response, but higher CPU load. Sensitivity Use sensitivity settings to tell Watchdog how it should decide if a pixel on the video has changed. If set to high, the software decides the pixel has changed even with a slight change on the pixel reading from the video device. Adjust the value based on camera quality and the scene. Motion detection areas Creating motion detection areas You can select multiple areas where Watchdog should watch for motion detection. To add a motion detection area, click "Add area". Click and drag the mouse to draw around the area you wish to enable motion detection. To remove the last added area, click Clear last added area. To erase all areas, click Clear all areas. (Note: you may need to restart Watchdog after you change the settings.) Show masks You can set a privacy mask for a camera. If you select show masks, only the select areas will be displayed and recorded in the video. Exclusive mode Use this instead of "Add area" if you want to enable motion detention on the whole image except some small areas. E.g. to block the window. When alarm is triggered You can instruct Watchdog to do the following when motion is detected. Record the video Check this box if you would like Watchdog to record video while motion detected. Email notification When motion is detected, Watchdog can alert you by emailing you the captured images. To enable email notification, simply check the box and type in your email address correctly. Please make sure you have set up a MAPI compatible email software like Microsoft Outlook Express, Microsoft Outlook or Netscape Communicator to enable Watchdog sending the emails. Click here if you wish to send email without configuring MAPI compatible software. Play a sound If you want a sound played when motion is detected, check the Play a sound box. Click the Browse button to select a sound file. Two sample .wav files are included for your convenience. Motion detection status After activating motion detection, you can see the motion meter changes on status bar of the video window. When alarm is triggered, you will see the motion meter turns red. Note: It is not recommended using motion detection for outdoors or areas that constantly have objects moving (e.g. convenient stores). The sudden change of sunlight may generate false alarm. Avoid using motion detection around window, with bad cameras or wireless cameras, dark area, or places that the lighting changes constantly. You may get false alarm when using motion detection in these areas.
