To configure the Water Level Detectionlevel detector, do the following:
- Go to the
Detection Tools tab- Detectors tab.
- Below the required camera,
click - click Create… → Category: Production Safety → Water
Level Detection- level detector.
By default, the detection tool detector is enabled and set to detect the water level in the frame.
If necessary, you can change the detection tool detector parameters. The list of parameters is given in the table:
| Parameter | Value | Description |
|---|
| Object features |
| Record mask to archive | Yes | By default, recording of the water level indicator to the archive is enabled. To disable it, select the No value |
| No |
| Video stream | Main stream | If the camera supports multistreaming, select the stream for which detection is needed. Selecting a low quality video stream reduces the load on the Server |
| Other |
| Enable | Yes | The |
detection tool | detector is enabled by default. To disable the |
detection tool the value Level Detection detection tool | detector name or leave the default name |
| Decoder mode | Auto | Select a processing resource for decoding video streams. When you select a GPU, a stand-alone graphics card takes priority (when decoding with NVIDIA NVDEC chips). If there is no appropriate GPU, the decoding will use the Intel Quick Sync Video technology. Otherwise, CPU resources will be used for decoding |

| Number of frames processed per second | 10 | Specify the number of frames that the |
detection tool will process | detector processes per second. The value must be in the |

| Frame size change | 1920 | The analyzed frames are scaled down to a specified resolution (1920 pixels on the longer side) by default. The following algorithm is used: - If the longer side of the source image exceeds the value specified in the Frame size change field, it is divided by two.
- If the resulting resolution falls below the specified value, the algorithm stops and this resolution will be used further.
- If the resulting resolution still exceeds the specified value, it is divided by two until it is less than the specified resolution.
| Info |
|---|
| For example, the source image resolution is 2048*1536, and the specified value is set to 1000. |
|
In In this case, the source resolution will be halved two times (512*384), as after the first division, the number of pixels on the longer side exceeds the specified value (1024 > 1000). |
|
If If detection is performed on a higher resolution stream and detection errors occur, we recommend reducing the compression. |
|
| Neural network file |
| Select a neural network file. The standard neural networks for different processor types are located in the C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroSDK directory. |
You You don't need to select the standard neural networks in this field, the system will automatically select the required one. If you use a custom neural network, enter a path to the file. | Info |

| For correct neural network operation on Linux OS, place the corresponding file in the /opt/AxxonSoft/DetectorPack/NeuroSDK directory. |
| Note |
|---|
| If you use standard neural network (training wasn't performed in operating conditions), we guarantee the overall accuracy of 80-95% and the percentage of false positives of 5-20%. |
|
| Basic settings |
| Maximum top value | 20 | Specify the maximum top value of the measuring scale. The value must be in the range [-1000, 1000] |
| Minimum bottom value | 0 | Specify the minimum bottom value of the measuring scale. The value must be in the range [-1000, 1000] |
| Neural network | Yes |
If If the water in the frame is transparent and the |
detection tool detector cannot correctly identify its level, |
use use Neural network: - If the No value is selected, the
|
detection tool - detector will work based on the algorithm without using the neural network on the CPU, ignoring the value specified in the Neural network file field.
If the Yes value is selected: If no value is selected in the Neural network file field, the system will automatically select the required standard neural network for the device specified in the Neural network mode field. If a custom neural network is selected in the Neural network file field that corresponds to the device specified in the Neural network mode field and is a water level neural network, a
|
detection tool detector with a neural network algorithm based on this neural network will be created.
| Note |

| If the neural network file is not specified correctly, the |
|
detection tool detector will not work. The neural network algorithm will recreate itself every 20 seconds. |

The water level indicator is displayed in the lower left corner. If the indicator is green, the water level is below high and critical marks. If the indicator is orange, the water level is at high mark, but below critical mark. A red indicator means that water level is above critical mark. |

Configuring Configuration of the Water Level Detection is level detector is complete.
When you have created the detection tooldetector, you can see a sensor on the layout in the Surveillance window.
If the sensor icon is green 
Image Modified, the water level is lower than both critical and high marks. If the icon is orange 
Image Modified, the water level is above the high mark, but below the critical mark. A red icon 
Image Modified means that the water level is above the critical mark.
You can also add a numerical value of the water level to the Surveillance window (see see Configuring display of water level detectionsensor).
