1. Go to the configuration panel for the Partition Of Control object.
   
2. Click the Add button (1). A dialog box for adding a sensor appears.
   
3. In the Type drop-down list, select the type of sensor from the sixteen types described previously (1).
4. In the Name field (2), enter the text that will be sent to Server of controlControl together with the alarm message. This text will be overlaid on the video during the captioning process.
5. In the ID drop-down list, select a Sensor object that has been previously created in the Axxon PSIM device tree (3).
6. In the Assignment to camera drop-down list, select a video camera from which the video frames or video clips should be requested (4).

7. To enable sending video frames to Server of controlControl when a sensor is activated, select the Transmit snapshots check box (5).

8. If you want for a video fragment to be sent to Server of controlControl when a sensor is triggered, select the Transmit video check box (6). 
9. In the Post-alarm time (s) field, enter the time delay between when a sensor is triggered and the time of access to the video archives, in seconds (7). The default value is 20 seconds. This parameter is necessary for guaranteed recording on camera.
10. In the Pre-alarm time (s) field, specify the amount of time for which you want to pre-record before sensor triggering, in seconds (8). This allows obtaining video frames depicting not only the very moment at which an alarm occurs, but a short time before.
11. If the Transmit snapshots check box was selected:
    1. In the Number of frames drop-down list, select the quantity of video frames to be transferred when a sensor is triggered (9).

    2. In the Interval (s) field, enter the length of time, in seconds, between video frames if more than one frame is to be sent (10). Thus when an alarm occurs, it is possible to send to Server of controlControl an entire sequence of frames that represent different points in time, which increases the chance of viewing the most valuable frames.

       Note
       title Attention!
       For snapshots transmitting more, as well as for video clips transmitting, it is necessary to create a script for stopping video recording on camera (see Sample script for stopping camera recording).

       
       

       Note
       title Attention!
       When specifying the Pre-alarm time (s), Number of frames, and Interval (s) settings, keep an eye on the configuration of the camera from which video frames are to be sent, and particularly on the Pre-alarm record setting... (s) setting. Pre-alarm record... (s) time on camera have to be greater or equal to Pre-alarm time (s) value in sensor settings.

       

12. If the Transmit video checkbox check box (1) was selected:

    1. In the Length (s) field (2), specify the length of the video fragment to send.

       

       Note
       title Attention!
       If the Not used value is selected in the Export to avi parameter (3), then the Length (sec.s)  parameter will be unavailable. In this case, the length will be determined by the size of the video fragment file in the video archive. To limit the length of the video fragment to be sent, use a script to stop recording on the camera (a sample script is found in the Sample script for stopping camera recording).

       
       

    2. In the Rate (Kbyte/s) field, enter the transmission rate for the video fragment (3).

    3. The Export to avi parameter (4) allows you to select the format and codec of the requested video clip:

       • Not used− the video clip will be exported as an archive with a set of directories and files from the VIDEO folder.

       • Initial format − the video clip will be exported to an AVI-file without transcoding.,

       • Xvid − the the video clip will be exported to an aviAVI-file with the Xvid codec.,

       • DivX − the the video clip will be exported to an aviAVI-file with the DivX codec.,

       • x264 − the the video clip will be exported to an aviAVI-file with the x264 codec.

         Note
         title Attention!
         The export to an avi-file with the specified codec is performed on the Agent Of control side using the AviExport.run module. The AviExport.run module version used on the Agent Of control should be no lower than 4.10.5.3776, and the required codec should be installed. Otherwise, an error Frame or video clip is not found (archive export error) will be received.

         Info

         title	Note

         If the Agent Of control version is lower than 11.0.1520, then the value of the Export to avi parameter will be automatically set to Not used without the possibility of changing it

         .

13. If it is necessary to overlay captions on video when a sensor is triggered, select the Captioning check box (11). In the Assignment to camera field, specify the camera on whose video you want to overlay captions (4).
14. In the Show for (s) drop-down list, select the amount of time for which you want captions to be displayed on video, in seconds (12).
15. Click OK (13).
