Configuration Variables

Each device has a number of configuration variables that can be adapted to particular scenarios. They are sent to the device as a response to the next update request sent from the device. These variables can be configured from the configure menu available under the device listing on the dashboard.

Name	Default Value	Purpose
uuid	Device Dependent	How the device is identified with the server. Never change to get reliable connection
frequency	20	How often the device sends updates over the network
image_quality	25	The JPEG compression quality. 100 indicates lossless transmission.
model	dnn/yolov3.weights	Path to the file including weights for the neural network (darknet).
config	dnn/config.cfg	Path to the configuration file describing the neural network.
confidence	0.2	Percentage of how sure we need to be to flag a human. Increase this if there are false detections.
nmsThreshold	0.1	How close bounding boxes need to be before they are considered the same person, expressed in normalized total box area
skipFrames	5	Number of frames to skip between detections when using the tracking subsystem
imageWidth	320	Width of the captured image. Influences tracking performance.
imageHeight	240	Height of the captured image. Influences tracking performance.
useOpenCL	1	Whether to use OpenCL acceleration for neural net computation on supported platforms
useCSRT	0	Whether to use KCF (default) or the more accurate but slower CSRT tracker
neuralNetQuality	416	Pixel dimensions of the neural net. No need to change under normal circumstances
maxDisappeared	50	Time in frames before a person is considered 'lost' from its marker
searchDistance	50	Area to search for a person around the original marker for subsequent detections
useTracking	1	Whether to use the slow but nice-looking tracking subroutine. Not available on IoT platforms
