Page History

The system supports use of four fixed sensors (vibration sensor, lock sensor, temperature sensor, and additional sensor) as well as 12 expansion sensors. There is also a separate additional device, "temperature array".

To configure the list of sensors in use:

1. Go to the configuration panel for the Partition Of Control object (Fig. 4.3 – 4.3—5).

2. In the Type drop-down list, select the type of sensor from the sixteen types described previously (see Fig. 4.3 – 4.3—6, 1).
3. In the Name field, enter the text that will be sent to Server of Control Server together with the alarm message. This text will be overlaid on the video during the captioning process (Fig. 4.3 – 4.3—6, 2).
4. In the ID drop-down list, select a Sensor object that has been previously created in the Intellect device tree (see Fig. 4.3 – 4.3—6, 3).
5. In the Attach Assignment to camera drop-down list, select a Camera object that has been previously created in the Intellect device tree (see Fig. 4.3 – 4.3—6, 4).

6. To enable sending video frames to Server of Control

   Server

   when a sensor is activated, select the

   transmit

   Transmit snapshots check box (

   see Fig. 4.3 – 4.3—6,

   Attach

   Assignment to camera field, specify the camera from which you want video frames to be sent (

   title Note.
   The settings for sending video frames and for sending video fragments are different.

   
   

2. If you want for a video fragment to be sent to Server of Control Server when a sensor is triggered, select the transmit Transmit video check box (seeFig. 4.3 – 4.3—6, 6). In the Attach Assignment to camera field, specify the camera from which you want video frames to be sent (see Fig. 4.3 – 4.3—6, 4).
3. In the Post-alarm time (sec.) field, enter the time delay between when a sensor is triggered and the time of access to the video archives, in seconds (see Fig. 4.3 – 4.3—6, 7). The default value is 20 seconds. This parameter is necessary for guaranteed recording on camera.
4. In the Pre-alarm time (sec.) field, specify the amount of time for which you want to pre-record before sensor triggering, in seconds (see Fig. 4.3 – 4.3—6, 8). This allows obtaining video frames depicting not only the very moment at which an alarm occurs, but a short time before.
5. In the Number of frames drop-down list, select the quantity of video frames to be transferred when a sensor is triggered (for video frame transmission mode) (see Fig. 4.3 – 4.3—6, 9).

6. In the Interval (sec.) field, enter the length of time, in seconds, between video frames if more than one frame is to be sent (

   see Fig. 4.3 – 4.3—6,

   10). Thus when an alarm occurs, it is possible to send to Server of Control

   Server

   an entire sequence of frames that represent different points in time, which increases the chance of viewing the most valuable frames (for video frame transmission mode).

2. In the Rate (KB/sec.) field, enter the transmission rate for the video fragment (for video fragment transmission mode) (see Fig. 4.3 – 4.3—8, 2).
3. To overlay captions on video when a sensor is triggered, select the captioning Captioning check box (11). In the Attach Assignment to camera field, specify the camera on whose video you want to overlay captions (see Fig. 4.3 – 4.3—6, 11).
4. In the Show for (sec.) drop-down list, select the amount of time for which you want captions to be displayed on video, in seconds (see Fig. 4.3 – 4.3—6, 12).
5. Click OK (see Fig. 4.3 – 4.3—6 , 13).
6. To perform monitoring to ensure that temperatures do not deviate from an allowed range, select the Temperature arraysensor set check box (see Fig. 4.3 – 4.3—5, 3). A set of DS18S20-type temperature sensors is used for temperature monitoring. Temperature sensors are connected via a two-wire MicroLAN to a MicroLAN network adapter, which in turn connects to the COM port of the computer on which Agent of Control is installed. The MicroLAN network adapter can be connected to the USB port of the computer on which Agent of Control is installed, by adding a RS232–USB adapter.
