Solutions¶
Solutions are processes for detecting incidents.
Click the Solutions menu on the left sidebar for this view.
Before you start¶
Please make sure that all Cameras are registered and activated in IRIS+ Essential.
When registering Solutions, make sure to take into account the Analysis Slots they would take up.
Analysis Slots¶
Each registered Solution uses a specific amount of resources. The number of Solutions able to be registered is limited by the hardware IRIS+ Essential is running on; see the table below for reference.
| Hardware | Number of resource slots |
|---|---|
| Nvidia Jetson NX | 1000 |
| x86-64 | 7000 |
Resource usage is indicated by a dark grey (so-called "Analysis Slots") bar in the upper right corner of the Solutions screen as well as on the New/Change Solution screens. Click the indicator to see how many free slots you have.
NOTE: If the dark grey indicator fills up, you will have reached your limit and cannot add another Solution.
One camera stream is able to handle multiple types of detections. Certain combination of solutions using that same camera do not increase resource usage.
Supported Solutions¶
Intrusion¶
An Intrusion alarm is triggered whenever a person or ground vehicle is detected in a restricted area. It has high accuracy and low false alarm rate even at long range and with different light conditions.
Multi Object Detection¶
A Multi Object Detection alarm is triggered whenever people or vehicles (ground, air and watercraft) are detected within a set time frame or location. It has high accuracy and low false alarm rate even at long range and with different light conditions. This method of detection is ideal for specialised use cases that require the detection, classification and filtering of objects, to determine if the following is true:
| Person or Vehicle is: | Use case example |
|---|---|
| at the wrong place | Truck blocking an emergency exit |
| at the wrong time | A vehicle is detected at night in a daytime-only parking lot |
| of the wrong type | Motorcycle occupying a bicycle parking spot |
Crowd¶
A Crowd alarm is triggered whenever the number of currently visible people reaches or exceeds a specific number. Multiple cameras can be associated with a single Crowd alarm, in which case the sum of the people triggers the alarm. This use case is ideal for detecting the extreme size of a queue or for detecting a potentially dangerous situation in a safety zone. Recommended for well lit areas.
Zone Crossing¶
You can use Zone Crossing to notify you if an object (a person or any one of the 8 vehicle classes) enters an unauthorised area from a certain direction. Detections from any other type of movement will be ignored and will not generate alarm notifications. This type of Solution is most useful if you would like to prevent access to an area from only certain directions but allow authorised employees leaving the office, for instance.
The zones and the direction from which entry should trigger alarms are configured via regions of interest by using the Camera Editor.
| Object movement | Will trigger alarms? |
|---|---|
| An object leaves the Target area (in any direction). | X |
| An object, coming from outside both areas, enters the Target area. | X |
| An object is is detected inside the Target area. | X |
| An object, coming from the Source area, enters the Target area. | ✓ |
Loitering¶
Loitering alerts you when an object (a person or any one of the 8 vehicle classes) has been staying in an area of your choosing for a specified amount of time.
Stopped¶
A Stopped alarm is triggered if a person or vehicle stays motionless for an amount of time set by the user. The level of motion for an object being considered as "stopped" is also configurable. As the detector requires a minimum object size of 110, it is recommended to use such alarms within medium-to-short-range to ensure accurate detection of objects.
Wrong Direction¶
Wrong Direction utilises object tracking to trigger an alarm if a person or vehicle is not moving in the direction set by the user in a given area. The direction and the area dimensions are configurable, as well as the degree above which objects are considered to be going in the wrong direction.
The zones and the direction(s) that are considered to be "right" are configured via regions of interest, by using the Camera Editor.
PPE (Personal Protective Equipment)¶
The personal protective equipment, or PPE detection triggers an alarm if the person(s) detected are not wearing either a protective helmet, a visibility vest, or both - you may check the lack of either or both types of equipment to be detected.
Hazardous Area¶
Hazardous Area may be used to trigger an alarm if a person or ground vehicle is detected in a hazardous or unsafe area. It has high accuracy and low false alarm rate even at long range and with different light conditions.
Fall Detection¶
[Fall Detection] is a tool for the monitoring and prevention of injury suffered by people tripping, slipping or otherwise falling to the floor and remain lying for an amount of time configured by the user.
Multi Object Counter¶
Multi Object Counter is a tool for classifying and measuring the amount of the chosen type(s) of objects. Multiple cameras can be associated with a single Multi Object Counter - This enables the measurement of different object classes, as well as a single object type in two or more separate locations (such as counting the sum of cars in two parking lot areas) as well.
The data produced by Multi Object Counters can be accessed in IRIS+ Essential, in the Events screen.
Traffic Counting¶
Traffic Counting measures the amount of people or vehicles entering, exiting and being inside a user-defined area; the number of objects inside being the result of subtracting the number of exiting objects from the number of entering ones. These values may be scheduled to reset to a configurable value in order to mitigate counting errors. Multiple cameras can be associated with a single Traffic Counting - This enables the measurement of different object classes per camera instance, as well as a single object type in two or more separate locations (such as counting the traffic going through multiple exits) as well.
The data produced by Traffic Counting can be accessed in IRIS+ Essential, in the Events screen.
