Alarm settings ■ Using the Alarm Setup Menu Display the alarm setup menu from the setup menu to configure alarm settings. First, display the alarm setup menu. 1. Display the setup menu (page 24), move the cursor to ALARM O, and then press the CAM (SET) button. This will display the alarm setup menu. **ALARM SETUP** MOTION DET OFF PRESET ALM OFF ALARM IN/OUT q e w RET TOP * The following sections numbered q to e explain how to use each of the alarm setup menu items. (1) Motion Detector Setting (MOTION DET) 1. Move the cursor to MOTION DET, and then tilt the joystick left or right to toggle it on and off. OFF :Turns off the motion detector. MODE 1 :Alarm signal is output when motion is detected in the image. Selecting MODE 1 and pressing the CAM (SET) button displays the mode 1 setting menu, which can be used for configuring detailed settings. MODE 2 :Alarm signal is output when the camera is covered by cloth, a lid, spray paint or something. Motion Detector The motion detector divides the screen into 48 blocks and monitors changes in the luminance in each block. When it detects any change (movement) in the image, it outputs an alarm signal. When a change (movement) in the image is detected while in the auto mode, the alarm signal is output and the camera stops at the preset position for a specified amount of time. Important: Conditions for Mode 2 Monitoring might not be possible in the following situations. • If only one part of the screen is not covered, or if the covering is translucent Also, false detection might occur in the following situations. • When extreme changes in lighting occur, such as turning lights on an off • If pedestrian or vehicle traffic is heavy Note: If you want to set a motion detector for each preset position, do the scene file setting. ● Configuring Detailed Motion Detector Settings for MODE 1 1. Move the cursor to MASK SET O, and then press the CAM (SET) button. This will display the mask setting screen. **MODE1** LEVEL DWELL TIME •••I•••131 - + 2S DISPLAY MODE ALARM OFF MASK SET RECOVER TIME OFF RET TOP 2. Mask the areas of the screen that you do not want the motion detector to monitor for movement. To mask screen areas, use the same procedure as step 5 under "SUPER-D 3 (Super Dynamic 3)" on page 28. After configuring mask settings, press the MON (ESC) button to return to the motion detector setting menu. 3. Move the cursor to ALARM, and then tilt the joystick left or right to toggle demo mode (see step 5) alarm output on and off. ON : Turns on alarm output in the demo mode. OFF : Turns off alarm output in the demo mode. 4. Move the cursor to DISPLAY MODE, and then press the CAM (SET) button. This activates the demo mode. Demo Mode The demo mode divides the screen into 48 blocks and monitors changes in the luminance in each block. It also masks any part of the picture where there is a change in average luminance that exceeds the currently specified detection sensitivity level. The demo mode results can be used to determine the optimum detection sensitivity level (step 5) and the areas of the screen that need to be masked (step 1). 5. Move the cursor to LEVEL, and then tilt the joystick left or right to set the detection sensitivity level. Shifting the setting towards the + side increases sensitivity, while shifting towards the - side decreases it. Repeat steps 4 and 5 until the optimum sensitivity level is obtained. Detection Conditions Object Size : The moving object must be larger than one of the screen blocks (1/48 of the total screen area). Subject Contrast: The contrast ratio between the background and the moving object must be at least 5 % (at the maximum LEVEL setting). Object Speed : The allowable time range for the object to pass from one edge of the screen to the other is 0.1 second to 0.8 second. Movement that is faster or slower than this cannot be detected. Important: Size and speed limitations are relaxed somewhat when the contrast ratio between the background and the moving object is large. -44-
