CORE

The CORE object is the global static object realized methods used to control state and to manage system objects of the Axxon PSIM software package. The extended possibilities for working with the CORE object are given when using scripts on JScript programming language – see the Programming Guide (JScript).

The CORE object sends events presented in the table. Procedure is started when the corresponding event appears.

Format of events procedure for the CORE object:

OnEvent("CORE","_id_","_event_")

Event	Description
DO_REACT	Event triggers reaction of some object in the system. Description of action which is to be performed is forwarded in the action parameter of this event. Examples of values of action parameter: SET_MARKRECT – sends when face recognizing on the video image; DEL_MARKRECT – sends when face disappearing from the video image. Can be other parameters of the event which can be monitored using the Debug window (see Programming Guide (JScript), section The Debug window). For example, if value of action parameter is SET_MARKRECT than number of camera on video image of which face is recognized is forwarding in the param5_val parameter. It shows name of parameter forwarded in the param5_name parameter. For the DEL_MARKRECT value the camera number is forwarding in the param0_val parameter.
SLAVE_CHANGED	Event is generated when Failover becomes active. It consists of the following parameters: old_slave_id – ID of the Computer object where cameras are moved from. new_slave_id – ID of the Computer object where cameras are moved to. CAM<n1, n2, ... > – where n1, n2, etc. are IDs of cameras moved to another parent Computer object. For example, CAM<4,6,7> – move cameras with IDs 4, 6, 7.
CREATE_OBJECT	Event triggers creation of an object. Parameters: objtype<> – object type, e.g. objtype<PERSON> for user creation. parent_id<> – identification number of the parent object. service_photo<> – when a user is created, the base64-encoded binary image of user photo can be put to this parameter. This is necessary for adding user photo immediately whet creating user in Access Manager.

Example.

When a face appears in the frame show the video from corresponding camera on the Monitor 2. When the face disappears – hide video from corresponding camera on the Monitor 2.

    {
        [ 
        Wait(2); 
        DoReact("MONITOR","2","REMOVE","cam<"+param0_val+">"); 
        ]
