CameraSentry can detect motion automatically and perform several actions to warn about possible intruders.
Motion Tracking can be enabled/disabled for all cameras at once, by using two commands in the Cameras menu: Start Motion Tracking for All Cameras and Stop Motion Tracking for All Cameras.
Also, it can be enabled/disabled for each camera by using the button on the camera toolbar.
The Motion Tracking response is configured in the Motion Tracking Tab in the Camera Settings window.
Motion Tracking Setup
Different actions can be performed after Motion is detected in a scene:
- Record Video: A video will be recorded.
- Sound Alarm: An audible alarm will sound. The default alarm sound will be used unless a different one is selected in the General tab. It must be a .WAV sound file.
- Send Email Notifications: A email message will be send, along with an image showing the motion, to the email address specified in the Email tab.
- Upload video to FTP Server (only enabled in the full version). This option works only if Record Video is checked.
There are three settings that configure motion detection.
- Threshold: Movement will be detected when the Threshold value is reached. If movement is not detected with minimum Threshold values (1), either increase the Sensitivity (move the trackbar to the right) or decrease the Object Size.
- Object Size: When the Threshold is reached, the Object Size (the moving one) will be computed, it the specified size is reached movement will be detected. The Object Size depends of the camera resolution, a 640x480 pixels camera will have far less pixels than a HD camera. To detect motion when the Threshold is reached, without checking the Object Size, set it to 0, this will speed-up motion processing, but may generate more false positives.
- Sensitivity: The Sensitivity trackbar goes from low (left side) to high (right side). In most scenes, low sensitivity is the best option, but if motion is not properly detected you may want to increase it. Notice that Motion Frame Size will change the camera resolution (only for motion detection purposes). If the video feed has a lot of noise, as happens when the light is not good, high sensitivity may trigger a lot of false alarms.
Usually, the best way to configure properly Motion Detection settings is to play a bit with them until motion is detected properly. The main setting is Threshold. If Object Size = 0, the Object Size will not be taken into account, only Threshold and Sensitivity will determine when Motion is detected.
There is an option in the General tab, called Show Motion Info. If this option is checked, the Threshold and Object Size values will be shown over the camera video feed. That helps users to see the values generated by different scenes, and configure the cameras appropriately.
