Recording / Analysis

This tab allows you to configure the recording of videos if this is done by Ethotrack with a webcam connected to the computer:

It also allows to program the sequencer which triggers the start and end of the analysis.

The sequencer is made up of events and actions connected by links. These links are represented by arrows, the direction of which indicates the chronological order of the progress of the various stages.

The events :

An event blocks the flow of the program until the condition defined in the event is true. When the condition is true, the sequencer can proceed to the next steps. The following steps which are actions are carried out and the following steps which are events are in turn tested until their condition is verified.

The event conditions are:

Immediately.

After a certain period.

When the animal is in motion for a certain time. Note: the animal is considered to be in motion if it remains motionless for less than the duration of immobility defined in the 'General' tab of the protocol.

When the animal is motionless for some time.

When the animal enters a zone for a certain period of time.

When the animal enters a zone one or more times. Note: The presence of the animal in the zone during the first evaluation of the event is counted as an entry if the option "Consider the presence of the animal in the zone during the first evaluation as an entry" is selected.

When the animal leaves a zone for a certain period of time.

When the animal leaves a zone one or more times. Note: The presence of the animal outside the zone during the first evaluation of the event is counted as an exit if the option "Consider the presence of the animal outside the zone during the first evaluation as an exit" is selected.

The actions :

actions are:

Start analysis.

Stop analysis.

In the example above the recording of the animal's position starts when it enters the zone 'Center' for the second time, and continues for a duration of 5 minutes.

Maximum duration:

It is possible to set a maximum duration from the beginning of the video. When this duration is reached, the analysis is stopped, whether the stop condition defined by the sequencer is reached or not.

Pre-saved configurations:

Select an item from the list to recall a pre-stored standard configuration.

Immediate start : The analysis starts immediately at the beginning of the video and continues until the end of the video.

Start after delay : The analysis starts after a certain delay and continues until the end of the video.

Start after delay, end after delay : The scan starts after a certain delay and ends automatically after a certain time.
