− 35 −Function Descriptions[13] Auto Pursuit FunctionDetects movement on the screen and calculates thelevel of movement.Subject pursued: Walking personArea:1x Zoom, object = a person at 8m distanceSpeed: 4km/hour - 6km/hourMotion detection: Uses the motion detection functionDetection area: 16 x 12, total of 192 blocksDetection conditions: Continuous movementdetection areaAuto Pursuit ON/OFF SettingSets auto pursuit to ON/OFF.Command: A0 34 00 0p CS FFp: OFF: 0、ON: 1Auto Pursuit Sensitivity SettingSets the sensitivity to brightness variation whendetecting motion.Higher sensitivity increases motion detection throughless brightness variation.Command: A0 34 01 0p CS FFp: 1-F (High sensitivity – Low sensitivity)Note:・When auto pursuit is set to ON, the ALARMMOTION setting is forcibly set to OFF.・Pursues the largest moving subject when severalmoving subjects are detected within one angle.・For Day/Night models, when the IR cut filter is inoperation the moving subject is not pursued.・When the zoom lens, focus lens are in operation, themoving subject is not pursued.。・When the PAN/TILT information is changed, themoving subject is not pursued・When LONG SHUTTER, SENSE UP is set, autopursuit cannot be set to ON.Moving Distance Query CommandReturns the distance to the distance derived from thecenter of gravity of the moving subject. This valuerepresents the distance. Calculate the PAN/TILTdistance adequately using this value.Command: 80 4A 07 CS FFResponse: C0 4A 07 0p 0q 0r 0s 0t 0u CS FFParameter description:p: Movement direction (Lateral) (1: Right, 2: Left)q: Movement direction (Vertical) (1: Up、2: Down)rs: Lateral movement distance (%)tu: Vertical movement distance (%)Up: 100%CenterRight: 100%Left: 100%Down: 100%Example: when p = 0x01, q = 0x01, rs = 0x64, tu =0x64, the PAN/TILT moves right: 100%,up: 100%. Control the PAN/TILT movingdistance so that the subject in the top rightcorner is in the Center.The minimum transmission interval of movementdistance query command is 150msec.
