Video stream and scene requirements for the Glow detector

Image requirements for the Glow detector

Hardware requirements for neural analytics operation

To configure the Glow detector, do the following:

  1. Go to the

...

  1.  Detectors tab.
  2. Below the required camera,

...

  1. click Create… → Category: Production Safety → Glow detector.

By default, the

...

detector is enabled and set to track light sources (lamps).

If necessary, you can change the

...

detector parameters. The list of parameters is given in the table:

Brightness threshold240Specify the sensitivity of the
detection tool
detector to changes in the state of the light source. You must select the required value empirically. For a dim light source, we recommend increasing the value of the parameter. The value must be in the range [0, 255]
Decoder modeAutoSelect 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

Sensitivity99Specify the sensitivity of the
detection tool
detector as a percentage. You must select the required value empirically. The higher the sensitivity, the greater the probability of a false

event. The lower the sensitivity, the greater the probability of missing an event. The value must be in the range [0, 100]
Time delta between frames100Specify the time interval between two measurements of light indication in seconds. The value must be in the range [0, 10000]

In To ensure that you receive accurate events from the detector, in the preview window , set you can specify one or several more detection areas with using the help of anchor points Image Modified (see Configuring the Detection Zone)a detection area). Detection areas must be located on each light source (lamp) and their dimensions must match the dimensions of the light sources.
