1. adhesion between targets if shooting horizontally and cause false alarm and failed alarm If using non WDR camera make sure there is no sky arising in the field of view it may cause part of image being too bright and dark which is not good for detection Try to make the direction between camera optical axis and target movement as vertical as possible which is to make the target displacement more obvious and more convenient for detection such as perimeter protection the camera should be installed along the perimeter direction The height of camera indoor installation is no lower than 3 meters and the height of outdoor installation is advised to be 5 10 meters 1f it is applied to the fence scene then the camera installation height has to be higher than the fence The camera should be installed firmly which is to avoid analysis result due to shaking The camera installation should avoid backlighting it is advised to use housing during outdoor application When it needs compensation light make sure the compensation light is uniformly distributed Pay attention to the distance between the compensation light and the camera it is advised to keep the distance of more than 2 meters the light is easy to attract mosquitoes if the 4 distance is too close it may increase the interference from rain and snow which may cause false alarm 2 3 2 Face detection installation requirement There are some factors which influence th2. if there is any similarity if not it will generate alarm pay attention to the following points about video scene change function A Avoid the scene with big difference of image brightness when turning on and off the light Image with light on Acceptable effect after light Unacceptable effect after off light off 20 B The scene needs to include some reference area which is not blocked by moving object and is changeless with some clear details See the scene in the left figure below it is not suitable for scene change detection because the moving crowd occupies most part of the image and there is no fixed area for reference which is easy to generate false alarm See the scene in the right figure below there is fixed area such as ceiling and wall for reference besides moving crowd which is suitable for detection analysis Unreasonable Reasonable C Avoid application in the tunnel and places with severe disturbance of vehicle lights Function Description Scene change is to detect if the video scene is changed due to external factors such as turning camera angle by people to change camera scene and it can activate record snapshot and alarm according to the judgment results It will generate alarm when the whole monitoring image changes due to the situations that the camera is blocked moved or strong light change ELLE Camera Network gt Video Detect gt Audio Detect gt gt Face Detect g
