SW-D7000U, 9CH. COLOR VIDEO MULTIPLEXERJVC PROFESSIONAL, IMAGING PRODUCTS 63In the ACTIVITY/INTRUSION sub-menu you may select by camera number the intended use ofmotion detection. (The factory default for each camera is ACTIVITY DETECTION.) This selectionwill result in different SETUP PARAMETERS for either INTRUSION DETECTION or ACTIVITYDETECTION.SETUP PARAMETERSActivity Parameters SetupThe menu for ACTIVITY PARAMETERS SETUP appears as:Activity Parameters SetupCamera : 01Sensitivity : 05Record Rate : 4XRelay Output : 02[CANCEL] [OK]Sensitivity:The motion detection sensitivity on each camera can be set to levels of 1-10. This setting is set on acamera-by-camera basis, and applies to all the ENABLED zones in any particular camera scene.Each of the 256 zones (16 x 16 grid) stores 256 grey levels of discrimination, averaged over thezone’s area. Changes in the 256 grey levels in a zone can be set as follows:" 1 = least sensitive setting = detect change of 100 of 256 grey levels in a zone, averaged overa zone." 10 = most sensitive setting = detect change of 5 of 256 grey levels in a zone, averaged overa zone.NOTE: The highest sensitivity of 10 is only reasonable if the video signal has extremely lownoise. (The factory default sensitivity setting is 5, for all cameras.)Recommendations:When setting sensitivity, choose the highest setting that does not result in very frequent ‘false’ motiondetections. The higher the sensitivity, the more likely it is that incidental movement will be detectedas motion, so if motion is indicated without apparent cause, reduce the sensitivity.When setting high sensitivity, such as 8, 9 or 10, it is important to ensure that sources of falsemotion, such as trees and bushes which may move in the wind, or windows which can reflect flashesof light, are eliminated from detection if possible. To do this, DISABLE the corresponding zones asdescribed above in SETUP ACTIVE ZONES.Sensitivity Scope:Refer to the description under SETUP ACTIVE ZONES sub-menu for further information on settingsensitivity.
