Intrusion Detection Detect when a person or moving object crosses a specified area. This can be used to detect actions such as when someone climbs over a barrier and enters a restricted area in a museum, etc. This determines that an object is entering when the decision point of the object detection frame enters the detection area and the specified duration has elapsed. Detection begins when the decision point enters the detection area. Intrusion Detection Frame Detected 4 Setting Page Decision Point Background Video Generated Video Changes Analysis Intrusion Detected  Audio Detection Detects audio input to the camera. These are set with [Event] > [Audio Detection] (P. 150), not with [Intelligent Function]. [Volume Detection]: Detects when volume level exceeds or falls below a reference volume. Notes on Intelligent Function Settings and Operations • When setting the Intelligent Function, do an actual detection test to confirm that detection will be performed correctly. • If a sudden change in lightness or darkness occurs within the entire screen, proper detection may not be possible for up to five minutes. • Detection will not be performed while the Intelligent Function is restarting. • If the camera is operated while configuring or using the Intelligent Function, [Restarting intelligent function. Please wait.] is displayed and the Intelligent Function will restart. • If the display switches between Day mode and Night mode, [Restarting intelligent function. Please wait.] is displayed and intelligent function will restart. • If [Basic] > [Video] > [All Videos] > [Video Size Set] settings on the Setting Page are changed, be sure to change the preset position settings ( S30VE S910F ) and Intelligent Function settings, and check operations. The Intelligent Function may not operate, depending on the settings. S30VE S910F • When the image is zoomed in (telephoto), detection may not work as expected. • Please set the Intelligent Function again if the angle of view has changed through camera operation, or the preset/home position has changed. • If [Status] in [Detection Settings] has [Enabled] when the camera position is fixed, control privileges cannot be obtained by the Viewer connected by the user without privileges for privileged camera control or RM Viewer. • If you use a preset registered with the digital zoom, the camera position at registration may not be able to be reproduced with a high degree of accuracy. Therefore, it is recommended that you use a preset registered in the optical zoom area for the intelligent function.  Difficult-to-Detect Subjects The following subjects may not be detected, or may result in erroneous detection. • Objects or areas where there is little contrast in color or brightness with the background may not be detected. • Small objects and changes on the screen may not be detected. • Partial or entire changes in brightness on the screen may trigger detection. 157
