New in V8.0
New advanced options for alarm mitigation.
Some encoder models have built in analytics. The ability to configure an encoder will depend on the model version, an available licence and user permissions.
Enabling & Sensitivity
Enter the analytics configuration from the Change analytics option from the settings menu.
Enable will turn the analytics on and off.
Analytics can only be enabled on physical inputs and if there is an available licence.
Detection sensitivity can be adjusted to either minimise false alarms or increase detection. As a starting point set the sensitivity to the middle (5) and adjust as required.
Analytic licensing
Analytics are a licensed feature. A licence is required for every input required. If there are no licences available the message No licence available will be shown. Licences can easily be moved between inputs by disabling the analytics on an input that is no longer required.
Physical and virtual inputs
Analytics can only be enabled on physical inputs, i.e. a single camera feed. Virtual inputs, such as Quad views and Picture in picture can not have analytics enabled. If the currently selected input can not have analytics enabled, the message Select an input to configure will be displayed.
Configuring analytics wizard
Select CONFIGURE to step through the analytics wizard.
If the camera is currently being VPTZ (Virtual Pan, Tilt and Zoom) the analytics cannot be configured. Reset the VPTZ on the encoder to allow configuration.
1 - Set a minimum object size
To set a minimum object size, adjust the area on screen by dragging the corners of the square. Objects that are smaller than the minimum height and width of the area will be ignored.
2 - Set a maximum object size
To set a maximum object size, adjust the area on screen by dragging the corners of the square. Objects that are larger than the minimum height and width of the area will be ignored.
1 - The detected object is too big and will not alarm
2 - The detected object is too wide and will not alarm
3 - The detected object is too small and will not alarm
4 - The detected object fits within the square. This will trigger an alarm
The location of the detection size is only for indication and does not affect detection.
3 - Detection region
Drag the corners of the region to mark an area. Objects within that area will trigger an alert. To detect the entire area, drag the corners to fill the video.
The region not shaded will alarm, in the above example only objects moving through the doorway will alert.
The region can be inverted to exclude an area from alarming.
Advanced options
The Advanced option is only available on selected encoders.

False alarm mitigation
Headlights/vehicles in scene : Enabling can mitigate false alarms in scenes containing vehicles, headlights or headlight effects, such as reflections. Adding headlights mitigation may reduce performance under normal conditions.
Insect/droplets on lens : Will filter out any insects or droplets on the lens that may cause false alarms. Adjust the sensitivity as required. A higher sensitivity can degrade detection performance.
Detection
Detect motion : Detect moving objects within the scene
Detect stationary : Detect objects that have stopped within the scene
Activation
Minimum presence : How long must an object be detected before triggering an alert.
Viewing analytic data
On receiving an alarm the object detected will be highlighted on the live video.
Objects outside the detection region will still be detected and will show as grey squares. If the object moves into the detection region it will alert.
