Video Intelligence

Overview

The NVR provides server based Video Intelligence for all cameras. Video Intelligence is a licenced

add-on for the NVR. Hardware-based (camera-based) Video Intelligence is not supported by the

NVR. The NVR supports two Video Intelligence features:

• Video Intelligence Search - a victor c

lient can search recorded video for a specific type of event.

• Video Intelligence Alerts - you can define V

ideo Intelligence settings that can be used to set up

Video Intelligence rules.

There are several types

of Video Intelligence rules available. These include:

• O

bject Detection - Used to detect people or objects moving into a region of

interest. This search is similar to a motion search, but only detects people or

objects on entry of the region of interest i.e. they will not be continuously

detected if they remain within the region of interest. If the object leaves the

camera view and returns, the search will detect them again. A separate event is

generated for each object that enters the region, even if the objects move into

the region at the same time, unlike motion detection that generates one event.

• Object Direction

- Used to detect objects moving in a certain direction through

a region of interest, for example, a car travelling the wrong way on a road.

• Objec

t Linger - Used to detect objects lingering in an area of interest. An object

is lingering if it is mostly stationary.

• Object Enter -

Used to detect objects entering a camera view through a region

of interest, for example, a doorway or threshold.

• O

bject Exit - Used to detect objects exiting a camera view through a region of

interest, for example, a doorway or threshold.

• Obje

ct Abandoned/Removed - Used to find changes to the background of a

scene in a region of interest, for example, use it to detect when a stationary

object was placed, moved or removed.

The Video Intelligence settings allow

you to define the parameters which will initiate an alarm (an

alarm rule). This will reduce the number of unwanted alarm events. The parameters available are

dependent on the type of Video Intelligence rules which are defined.

Video Intelligence provides us

eful information only if recording is enabled on the camera. Your

camera should be configured with Only Record on Alarm or Recording Always with Alarm On

recording modes. For further information on camera recording modes refer to Table 8-1 Recording

Statuses on page 107.

Video Intelligence events will create entries in the v

ictor site manager database. If required you

can use the Reports feature in victor unified client to retrieve event information.
