 Audio Detection Detects audio input to the camera. There are two types of detection. These are set with [Event] > [Audio Detection] (P. 152), not with [Intelligent Function]. [Volume Detection]: Detects when volume level exceeds or falls below a reference volume. [Scream Detection]: Detects screams or cries from people. 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 shown 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 ( HM4x S30 S31 ) and Intelligent Function settings, and check operations. The Intelligent Function may not operate, depending on the settings. HM4x S30 S31 • When the image is zoomed in (telephoto), detection may not work as expected. HM4x S30 • 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 [Enable] 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. Also, the preset tour will no longer run. HM4x • 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. HM4x S30  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. • When there are multiple overlapping objects, there may be a change in detection. For example, objects passing may either not be detected or the timing of detection may be incorrect. • When there are large numbers of objects in the scene, objects may not be properly detected. Registering Presets HM4x S30 S31 It is strongly recommended that you register the camera angle as a preset in advance and lock the camera to that position when using video detection. It is also recommended that the angle of view that captures targeted objects at a larger ratio be used. For details on preset registration, please refer to "[Camera] > [Preset] Registering Presets" (P. 118). 160
