Event Management

When something happens on the camera site, such as someone walks by, the door opens or

closes, a fire breaks out or the sun goes down

– these are all Events. Events which occur in

the environment or were preprogrammed in the camera may be used as Triggers. Triggers

cause the device to react with Responses. The link between trigger and response is governed

by Event Rules. Event rules become active or inactive based upon a weekly Schedule. Each

event rule detects one specific trigger and may initiate multiple responses. An example rule

would be for the NVR server to send emails to alert the supervisor (Response 1) and trigger

alarm (Response 2) when motion detection from camera is triggered (Trigger) during the

event handing active period (Schedule).

How Does NVR Handle Events

In NVR 3.0 system, each device can be involved in several event rules. As different device

models have different capabilities, the supported event trigger types would vary. For example,

a PIR built-in camera can execute a PIR-triggered event rule, while this option is not provided

for other models without this feature; similarly, the supported response types would vary by

device models, such like Go-to-Preset behavior can only be executed by PTZ devices. The

below chart shows the NVR server supported Trigger types and Response types. Once a

device is added to the NVR server, the server would create empty rules with compatible trigger

types for you to configure.
